text-align: center;
padding: 20px;
background: lightblue;
}
.arrow {
position: absolute;
top: 50%;
transform: translateY(-50%);
background: #333;
color: #fff;
border: none;
padding: 10px;
cursor: pointer;
z-index: 1000;
}
#prev {
left: 10px;
}

### JavaScript
document.addEventListener('DOMContentLoaded', () => {
const slides = document.querySelectorAll('.slide');
const tabs = document.querySelectorAll('.tab');
const prevButton = document.getElementById('prev');
const nextButton = document.getElementById('next');
let currentIndex = 0;
function updateSlider(index) {
const slider = document.querySelector('.slider');
slider.style.transform = `translateX(-${index * 100}%)`;
slides.forEach((slide, idx) => slide.classList.toggle('active', idx === index));
tabs.forEach((tab, idx) => tab.classList.toggle('active', idx === index));
}
prevButton.addEventListener('click', () => {
currentIndex = (currentIndex > 0) ? currentIndex - 1 : slides.length - 1;
updateSlider(currentIndex);
});
nextButton.addEventListener('click', () => {
currentIndex = (currentIndex < slides.length - 1) ? currentIndex + 1 : 0;
updateSlider(currentIndex);
});
tabs.forEach((tab) => {
tab.addEventListener('click', () => {
currentIndex = parseInt(tab.getAttribute('data-index'));
updateSlider(currentIndex);
});
});
updateSlider(currentIndex); // Initialize
});
### Features
1. **Arrows:** Navigate left and right through slides.
2. **Tabs:** Clicking on a tab jumps to the corresponding slide.
3. **Responsiveness:** Adjust `slider-container` width in CSS as needed.
This implementation works as a standalone slider. You can integrate it into your project or modify it to suit your needs. Let me know if you need any adjustments!

– You can manage the slides directly from the WPBakery builder interface.
Let me know if you need further assistance!
### **1. Update the Shortcode**
Modify the `custom_slider_shortcode` function to handle images. You'll also need to update the way the slides are processed.
function custom_slider_shortcode($atts, $content = null) {
// Default attributes
$atts = shortcode_atts([
'slides' => '',
], $atts);
// Convert slides into an array
$slides = json_decode($atts['slides'], true);
// Generate the slider HTML
ob_start(); ?>
<div class="slider-container">
<div class="slider-wrapper">
<?php foreach ($slides as $index => $slide): ?>
<div class="slide <?php echo $index === 0 ? 'active' : ''; ?>">
<img src="<?php echo esc_url($slide['image']); ?>" alt="<?php echo esc_attr($slide['tab']); ?>" />
<div class="slide-content"><?php echo esc_html($slide['content']); ?></div>
</div>
<?php endforeach; ?>
</div>
<!-- Arrows -->
<div class="slider-controls">
<button class="arrow prev">❮</button>
<button class="arrow next">❯</button>
</div>
<!-- Tabs -->
<div class="slider-tabs">
<?php foreach ($slides as $index => $slide): ?>
<button class="tab <?php echo $index === 0 ? 'active' : ''; ?>" data-index="<?php echo $index; ?>">
<?php echo esc_html($slide['tab']); ?>
</button>
<?php endforeach; ?>
</div>
</div>
<?php
return ob_get_clean();
}
add_shortcode('custom_slider', 'custom_slider_shortcode');
### **2. Update the WPBakery Element Registration**
Update the WPBakery element registration to include fields for image upload and tab names:
add_action('vc_before_init', 'register_custom_slider_element');
function register_custom_slider_element() {
vc_map([
'name' => 'Custom Slider',
'base' => 'custom_slider', // Shortcode base
'category' => 'Content',
'params' => [
[
'type' => 'param_group',
'heading' => 'Slides',
'param_name' => 'slides',
'description' => 'Add slides for the slider.',
'params' => [
[
'type' => 'attach_image',
'heading' => 'Slide Image',
'param_name' => 'image',
'description' => 'Upload an image for this slide.',
],
[
'type' => 'textfield',
'heading' => 'Slide Content',
'param_name' => 'content',
'description' => 'Enter the content for the slide.',
],
[
'type' => 'textfield',
'heading' => 'Tab Name',
'param_name' => 'tab',
'description' => 'Enter the name for this tab.',
],
],
],
],
]);
}
### **3. Adjust the JavaScript File**
Ensure the JavaScript for the slider is correctly managing the tab clicks and slide transitions, as previously defined. You don't need to change the JavaScript unless you want to enhance functionality.
### **4. Usage in WPBakery**
1. Open a page in WPBakery.
2. Add the **Custom Slider** element.
3. Add slides by filling in the image upload, slide content, and tab name fields.
### **Result**
Now, when you add the custom slider in WPBakery, you can:
– Upload an image for each slide.
– Provide specific content for each slide.
– Define the name for each tab.
This allows for a more interactive and visually appealing slider that can be managed directly from the WPBakery interface.
### **Final Note**
Make sure your theme has the appropriate styles in the `custom-slider.css` file to handle the images and ensure the slider looks good. If you need further adjustments or features, feel free to ask!
Here's how to implement it:
### **1. Update the WPBakery Element Registration**
Replace the existing 'Slide Content' field with a WYSIWYG editor. You will use `wpb_map` to define the parameters for the slider. Here’s how to do it:
add_action('vc_before_init', 'register_custom_slider_element');
function register_custom_slider_element() {
vc_map([
'name' => 'Custom Slider',
'base' => 'custom_slider', // Shortcode base
'category' => 'Content',
'params' => [
[
'type' => 'param_group',
'heading' => 'Slides',
'param_name' => 'slides',
'description' => 'Add slides for the slider.',
'params' => [
[
'type' => 'attach_image',
'heading' => 'Slide Image',
'param_name' => 'image',
'description' => 'Upload an image for this slide.',
],
[
'type' => 'textarea_html',
'heading' => 'Slide Content',
'param_name' => 'content',
'description' => 'Enter the content for the slide. You can use formatting options.',
],
[
'type' => 'textfield',
'heading' => 'Tab Name',
'param_name' => 'tab',
'description' => 'Enter the name for this tab.',
],
],
],
],
]);
}
### **2. Update the Shortcode Function**
Make sure the shortcode function can handle HTML content from the WYSIWYG editor. The `content` parameter should already be properly processed. Here's how your existing shortcode function looks with the WYSIWYG integration:
function custom_slider_shortcode($atts, $content = null) {
// Default attributes
$atts = shortcode_atts([
'slides' => '',
], $atts);
// Convert slides into an array
$slides = json_decode($atts['slides'], true);
// Generate the slider HTML
ob_start(); ?>
<div class="slider-container">
<div class="slider-wrapper">
<?php foreach ($slides as $index => $slide): ?>
<div class="slide <?php echo $index === 0 ? 'active' : ''; ?>">
<img src="<?php echo esc_url($slide['image']); ?>" alt="<?php echo esc_attr($slide['tab']); ?>" />
<div class="slide-content"><?php echo $slide['content']; ?></div>
</div>
<?php endforeach; ?>
</div>
<!-- Arrows -->
<div class="slider-controls">
<button class="arrow prev">❮</button>
<button class="arrow next">❯</button>
</div>
<!-- Tabs -->
<div class="slider-tabs">
<?php foreach ($slides as $index => $slide): ?>
<button class="tab <?php echo $index === 0 ? 'active' : ''; ?>" data-index="<?php echo $index; ?>">
<?php echo esc_html($slide['tab']); ?>
</button>
<?php endforeach; ?>
</div>
</div>
<?php
return ob_get_clean();
}
add_shortcode('custom_slider', 'custom_slider_shortcode');
### **3. Enqueue the Necessary Scripts and Styles**
Ensure your theme or plugin enqueues any necessary CSS and JavaScript, as outlined in previous messages. Here’s a reminder of the script enqueueing process:
function custom_slider_assets() {
// CSS
wp_enqueue_style('custom-slider-css', get_template_directory_uri() . '/css/custom-slider.css');
// JavaScript
wp_enqueue_script('custom-slider-js', get_template_directory_uri() . '/js/custom-slider.js', ['jquery'], null, true);
}
add_action('wp_enqueue_scripts', 'custom_slider_assets');
### **4. Usage in WPBakery**
1. Open a page in WPBakery.
2. Add the **Custom Slider** element.
3. Add slides by filling in the image upload, slide content (using the WYSIWYG editor), and tab name fields.
### **Final Note**
This modification will allow users to format the content of each slide using the WYSIWYG editor, making it easier to add styled text, images, and other HTML elements directly in the slider. If you have any more questions or need additional features, feel free to ask!
Here’s how to customize the widths:
### **1. Add Custom CSS to WPBakery Editor**
You can add custom styles to the WPBakery editor by using the `admin_enqueue_scripts` action. Add the following code to your theme’s `functions.php` file:
function custom_wpbakery_editor_styles() {
// Add custom styles for WPBakery editor
?>
<style>
.vc_shortcode-param {
max-width: 100% !important; /* Set maximum width to 100% */
}
.wpb_textarea {
width: 100% !important; /* Full width for text areas */
min-height: 200px; /* Adjust height as needed */
}
.wpb_tinymce {
width: 100% !important; /* Full width for WYSIWYG editor */
}
.wpb_param_group {
width: 100% !important; /* Full width for param groups */
}
</style>
<?php
}
add_action('admin_head', 'custom_wpbakery_editor_styles');
### **2. Customize the Text Area Width**
If you want to specifically target the text area in the WPBakery settings, you can adjust its width and height in the CSS above. The `min-height` property can be adjusted according to your needs to give more room for editing.
### **3. Testing Your Changes**
1. Save your changes in the `functions.php` file.
2. Go to a page in the WPBakery editor where you have added your **Custom Slider** element.
3. Open the slide settings, and you should see that the WYSIWYG editor and text area now take up more space, making it easier to work with.
### **Final Notes**
– The styles added will only affect the WPBakery backend editor, not the frontend of your site.
– Make sure to test your changes in different browsers to ensure compatibility.
– If you want further customization, you can continue tweaking the CSS to match your preferences.
If you have any further questions or need additional modifications, feel free to ask!
set default width of opened widget box
Here's how to do it:
### **1. Add Custom CSS for the Widget Box**
Add the following code to your theme’s `functions.php` file. This code sets the width of the opened widget box for your custom slider element in the WPBakery editor:
function custom_wpbakery_widget_box_width() {
?>
<style>
/* Set default width for the opened custom slider widget box */
.vc_shortcode-param {
width: 600px !important; /* Adjust this value to set the desired width */
}
/* Ensure text areas and WYSIWYG editors are also full width */
.wpb_textarea, .wpb_tinymce {
width: 100% !important; /* Full width for text areas and WYSIWYG editor */
min-height: 200px; /* Adjust height as needed */
}
</style>
<?php
}
add_action('admin_head', 'custom_wpbakery_widget_box_width');
### **2. Explanation of the CSS**
– `.vc_shortcode-param`: This class is used for the parameters in the WPBakery shortcode settings. The width is set to `600px` (you can adjust this value as needed).
– `.wpb_textarea` and `.wpb_tinymce`: These classes ensure that the text areas and WYSIWYG editors occupy the full width of their parent container.
– `min-height`: This property for the WYSIWYG editor can be adjusted to ensure that there’s enough vertical space for content editing.
### **3. Testing Your Changes**
1. Save your changes in the `functions.php` file.
2. Go to a page in the WPBakery editor where you have added your **Custom Slider** element.
3. Open the settings for the custom slider. The widget box should now have the specified width when opened.
### **Final Notes**
– You can adjust the width in the CSS to suit your design preferences.
– This change will only affect the WPBakery editor in the WordPress admin area and will not affect the frontend display of your site.
– If you have additional styling needs, you can further customize the CSS as necessary.
If you have more questions or need further assistance, feel free to ask!
### **1. Modify the CSS for Your Custom Slider Element**
You can use a specific class associated with your custom slider element to set the width. Below is the updated code you can add to your `functions.php` file:
function custom_wpbakery_slider_box_width() {
?>
<style>
/* Set default width for the opened custom slider widget box */
.vc_shortcode-param.custom-slider-param {
width: 600px !important; /* Adjust this value to set the desired width */
}
/* Ensure text areas and WYSIWYG editors are also full width */
.vc_shortcode-param.custom-slider-param .wpb_textarea,
.vc_shortcode-param.custom-slider-param .wpb_tinymce {
width: 100% !important; /* Full width for text areas and WYSIWYG editor */
min-height: 200px; /* Adjust height as needed */
}
</style>
<?php
}
add_action('admin_head', 'custom_wpbakery_slider_box_width');
### **2. Update the WPBakery Element Registration**
When you register your custom slider element, add a custom class to the parameters that will allow you to target them specifically. Update the `vc_map` registration as follows:
add_action('vc_before_init', 'register_custom_slider_element');
function register_custom_slider_element() {
vc_map([
'name' => 'Custom Slider',
'base' => 'custom_slider', // Shortcode base
'category' => 'Content',
'params' => [
[
'type' => 'param_group',
'heading' => 'Slides',
'param_name' => 'slides',
'description' => 'Add slides for the slider.',
'params' => [
[
'type' => 'attach_image',
'heading' => 'Slide Image',
'param_name' => 'image',
'description' => 'Upload an image for this slide.',
],
[
'type' => 'textarea_html',
'heading' => 'Slide Content',
'param_name' => 'content',
'description' => 'Enter the content for the slide. You can use formatting options.',
],
[
'type' => 'textfield',
'heading' => 'Tab Name',
'param_name' => 'tab',
'description' => 'Enter the name for this tab.',
],
],
'class' => 'custom-slider-param' // Add this line to set a specific class for the parameter group
],
],
]);
}
### **3. Explanation of the Code**
– **CSS Specificity**: The CSS is now targeting only the parameters of your custom slider element by using the class `.custom-slider-param`. This prevents it from affecting other WPBakery elements.
– **Custom Class**: The `class` parameter is added to the `param_group`, allowing the custom styles to apply only to your slider element's parameter group.
### **4. Testing Your Changes**
1. Save your changes in the `functions.php` file.
2. Go to a page in the WPBakery editor where you have added your **Custom Slider** element.
3. Open the settings for the custom slider. The widget box should now have the specified width when opened.
### **Final Notes**
– Adjust the width in the CSS as needed.
– This change is specific to your custom slider and will not affect other elements in WPBakery.
– If you require further adjustments or features, feel free to ask!
### **1. Ensure Proper Registration of the `textarea_html` Parameter**
Make sure that you are correctly defining the `textarea_html` parameter in your `vc_map` configuration. Here's a sample code snippet:
add_action('vc_before_init', 'register_custom_slider_element');
function register_custom_slider_element() {
vc_map([
'name' => 'Custom Slider',
'base' => 'custom_slider', // Shortcode base
'category' => 'Content',
'params' => [
[
'type' => 'param_group',
'heading' => 'Slides',
'param_name' => 'slides',
'description' => 'Add slides for the slider.',
'params' => [
[
'type' => 'attach_image',
'heading' => 'Slide Image',
'param_name' => 'image',
'description' => 'Upload an image for this slide.',
],
[
'type' => 'textarea_html',
'heading' => 'Slide Content',
'param_name' => 'content',
'description' => 'Enter the content for the slide. You can use formatting options.',
],
[
'type' => 'textfield',
'heading' => 'Tab Name',
'param_name' => 'tab',
'description' => 'Enter the name for this tab.',
],
],
],
],
]);
}
### **2. Use `vc_param_group` for Proper Handling**
Ensure that you're using `vc_param_group` correctly to allow for saving the contents of the `textarea_html`. Here’s how you can modify the shortcode function to handle the content properly:
function custom_slider_shortcode($atts, $content = null) {
// Default attributes
$atts = shortcode_atts([
'slides' => '',
], $atts);
// Decode slides into an array
$slides = json_decode($atts['slides'], true);
// Generate the slider HTML
ob_start(); ?>
<div class="slider-container">
<div class="slider-wrapper">
<?php if (!empty($slides)): ?>
<?php foreach ($slides as $index => $slide): ?>
<div class="slide <?php echo $index === 0 ? 'active' : ''; ?>">
<img src="<?php echo esc_url($slide['image']); ?>" alt="<?php echo esc_attr($slide['tab']); ?>" />
<div class="slide-content"><?php echo wp_kses_post($slide['content']); ?></div>
</div>
<?php endforeach; ?>
<?php endif; ?>
</div>
<!-- Arrows -->
<div class="slider-controls">
<button class="arrow prev">❮</button>
<button class="arrow next">❯</button>
</div>
<!-- Tabs -->
<div class="slider-tabs">
<?php foreach ($slides as $index => $slide): ?>
<button class="tab <?php echo $index === 0 ? 'active' : ''; ?>" data-index="<?php echo $index; ?>">
<?php echo esc_html($slide['tab']); ?>
</button>
<?php endforeach; ?>
</div>
</div>
<?php
return ob_get_clean();
}
add_shortcode('custom_slider', 'custom_slider_shortcode');
### **3. Debugging the Save Process**
If the above steps don’t solve the issue, consider the following:
– **Console Errors**: Check your browser console for JavaScript errors that might prevent the saving process in the WPBakery editor.
– **Server Errors**: Check the server logs for PHP errors that may indicate issues in processing or saving the data.
– **Plugin Conflicts**: Ensure there are no conflicts with other plugins that might affect how WPBakery handles custom fields.
### **4. Testing the Changes**
1. After making these changes, go to the WPBakery editor.
2. Open your **Custom Slider** element and enter some content in the `Slide Content` textarea.
3. Save the page and check if the content persists after refreshing the editor.
### **5. Save and Load Content**
Make sure that your shortcode and any associated database entries properly handle the loading and saving of content. The `wp_kses_post` function is used to safely display content that may contain HTML formatting.
### **Final Note**
If you still encounter issues with saving the `textarea_html` content, it might be beneficial to check the version of WPBakery you are using or look for any updates that address this behavior. Additionally, if you need further assistance, please provide more details about the issue or any error messages you encounter.
// Default attributes
$atts = shortcode_atts([
'slides' => '',
], $atts);
// Decode slides into an array
$slides = json_decode($atts['slides'], true);
// Generate the slider HTML
ob_start(); ?>
### **1. Ensure Data is Passed Correctly**
First, confirm that the data is being passed correctly from the WPBakery Page Builder. In your `vc_map` configuration, make sure you have defined the `slides` parameter correctly as a `param_group`, and it includes the fields for images, content, and tab names.
Here's an example of how the `vc_map` should look:
add_action('vc_before_init', 'register_custom_slider_element');
function register_custom_slider_element() {
vc_map([
'name' => 'Custom Slider',
'base' => 'custom_slider',
'category' => 'Content',
'params' => [
[
'type' => 'param_group',
'heading' => 'Slides',
'param_name' => 'slides',
'description' => 'Add slides for the slider.',
'params' => [
[
'type' => 'attach_image',
'heading' => 'Slide Image',
'param_name' => 'image',
'description' => 'Upload an image for this slide.',
],
[
'type' => 'textarea_html',
'heading' => 'Slide Content',
'param_name' => 'content',
'description' => 'Enter the content for the slide.',
],
[
'type' => 'textfield',
'heading' => 'Tab Name',
'param_name' => 'tab',
'description' => 'Enter the name for this tab.',
],
],
],
],
]);
}
### **2. Check the Data in the Shortcode Function**
Next, ensure that the data is correctly decoded and accessed within your `custom_slider_shortcode` function. You can add debug statements to check if the `slides` data is being correctly passed. Here's the modified version of your shortcode function with debugging:
function custom_slider_shortcode($atts, $content = null) {
// Default attributes
$atts = shortcode_atts([
'slides' => '',
], $atts);
// Decode slides into an array
$slides = json_decode($atts['slides'], true);
// Debugging: Check if slides are being decoded correctly
if (empty($slides)) {
return '<div>No slides available.</div>'; // Temporary message for debugging
}
// Generate the slider HTML
ob_start(); ?>
<div class="slider-container">
<div class="slider-wrapper">
<?php if (!empty($slides)): ?>
<?php foreach ($slides as $index => $slide): ?>
<div class="slide <?php echo $index === 0 ? 'active' : ''; ?>">
<img src="<?php echo esc_url($slide['image']); ?>" alt="<?php echo esc_attr($slide['tab']); ?>" />
<div class="slide-content"><?php echo wp_kses_post($slide['content']); ?></div>
</div>
<?php endforeach; ?>
<?php else: ?>
<div>No slides available.</div>
<?php endif; ?>
</div>
<!-- Arrows -->
<div class="slider-controls">
<button class="arrow prev">❮</button>
<button class="arrow next">❯</button>
</div>
<!-- Tabs -->
<div class="slider-tabs">
<?php foreach ($slides as $index => $slide): ?>
<button class="tab <?php echo $index === 0 ? 'active' : ''; ?>" data-index="<?php echo $index; ?>">
<?php echo esc_html($slide['tab']); ?>
</button>
<?php endforeach; ?>
</div>
</div>
<?php
return ob_get_clean();
}
add_shortcode('custom_slider', 'custom_slider_shortcode');
### **3. Verify the Output**
1. **Debugging Output**: After making the changes, refresh the page where you are using the shortcode. If you see the message "No slides available," it indicates that the `slides` parameter is not being passed correctly. If you don't see this message and the slider is empty, check if the images and content are set in WPBakery.
2. **Check the `slides` Parameter**: If the `slides` parameter is empty, double-check your WPBakery setup to ensure you are correctly adding slides in the element settings.
### **4. Ensure Proper Enqueuing of Scripts and Styles**
Make sure you have the necessary JavaScript and CSS files for your slider functionality. If your slider requires additional JavaScript for functionality (like moving between slides), ensure you have that properly enqueued.
### **5. Final Testing**
After following these steps, make sure to:
– Save your changes in WPBakery.
– Refresh the front-end view of your site where the shortcode is used to see if the slider now displays correctly.
If you continue to have issues, please provide more details on how you're using the shortcode, or any specific messages or results you encounter during testing.
### **1. Check the WPBakery Element Configuration**
Ensure that you've correctly configured the `vc_map` for your custom slider element, especially the `param_group` that holds the slides. Here's the relevant code:
add_action('vc_before_init', 'register_custom_slider_element');
function register_custom_slider_element() {
vc_map([
'name' => 'Custom Slider',
'base' => 'custom_slider',
'category' => 'Content',
'params' => [
[
'type' => 'param_group',
'heading' => 'Slides',
'param_name' => 'slides',
'description' => 'Add slides for the slider.',
'params' => [
[
'type' => 'attach_image',
'heading' => 'Slide Image',
'param_name' => 'image',
'description' => 'Upload an image for this slide.',
],
[
'type' => 'textarea_html',
'heading' => 'Slide Content',
'param_name' => 'content',
'description' => 'Enter the content for the slide.',
],
[
'type' => 'textfield',
'heading' => 'Tab Name',
'param_name' => 'tab',
'description' => 'Enter the name for this tab.',
],
],
],
],
]);
}
### **2. Verify Adding Slides in WPBakery**
1. **Add the Custom Slider**: When you add your custom slider element in the WPBakery editor, ensure you are actually adding slides within the **Slides** parameter group. You should see an option to add items to this group.
2. **Fill Out Each Slide**: For each slide you add, make sure you:
– Upload an image in the **Slide Image** field.
– Enter content in the **Slide Content** field.
– Specify a name for the **Tab Name**.
### **3. Check the Data Passed to the Shortcode**
Next, we need to ensure that the data is being correctly passed and retrieved in your shortcode. The `slides` parameter should be a JSON-encoded string that contains the slide data.
1. **Check the Output of the `slides` Parameter**: You can log the output of the `slides` parameter to see what is being passed:
function custom_slider_shortcode($atts, $content = null) {
// Default attributes
$atts = shortcode_atts([
'slides' => '',
], $atts);
// Debugging: Log the slides attribute
error_log('Slides attribute: ' . print_r($atts['slides'], true));
// Decode slides into an array
$slides = json_decode($atts['slides'], true);
// Debugging: Check if slides are being decoded correctly
if (empty($slides)) {
return '<div>No slides available.</div>'; // Temporary message for debugging
}
// Generate the slider HTML
ob_start(); ?>
<div class="slider-container">
<div class="slider-wrapper">
<?php if (!empty($slides)): ?>
<?php foreach ($slides as $index => $slide): ?>
<div class="slide <?php echo $index === 0 ? 'active' : ''; ?>">
<img src="<?php echo esc_url($slide['image']); ?>" alt="<?php echo esc_attr($slide['tab']); ?>" />
<div class="slide-content"><?php echo wp_kses_post($slide['content']); ?></div>
</div>
<?php endforeach; ?>
<?php else: ?>
<div>No slides available.</div>
<?php endif; ?>
</div>
<!-- Arrows -->
<div class="slider-controls">
<button class="arrow prev">❮</button>
<button class="arrow next">❯</button>
</div>
<!-- Tabs -->
<div class="slider-tabs">
<?php foreach ($slides as $index => $slide): ?>
<button class="tab <?php echo $index === 0 ? 'active' : ''; ?>" data-index="<?php echo $index; ?>">
<?php echo esc_html($slide['tab']); ?>
</button>
<?php endforeach; ?>
</div>
</div>
<?php
return ob_get_clean();
}
add_shortcode('custom_slider', 'custom_slider_shortcode');
– This will log the value of the `slides` attribute to your server's error log (usually located in `wp-content/debug.log` if WP debugging is enabled). Check this log after adding the slider to see what is being passed.
### **4. Verify the Data Structure**
The `slides` parameter should be a JSON object structured like this after being processed by WPBakery:
[
{
"image": "image_id_1",
"content": "<p>Slide content 1</p>",
"tab": "Tab 1"
},
{
"image": "image_id_2",
"content": "<p>Slide content 2</p>",
"tab": "Tab 2"
}
]
Make sure that this format is being respected when you add slides in the WPBakery editor.
### **5. Final Check**
– **Re-save the Page**: After adding slides, make sure to save the page in WPBakery and refresh the front-end to see if the changes take effect.
– **Check for Caching**: If you have any caching plugins active, clear the cache after making changes to ensure you see the latest updates.
If after these steps you're still not seeing any slides, please provide more details on the steps you've taken or any specific behaviors you observe in WPBakery. This information will help in diagnosing the issue further.
### Step-by-Step Debugging Process
1. **Check the WPBakery Settings**:
– Ensure your custom slider element is properly registered in WPBakery. Check that the `vc_map` configuration is set up correctly, particularly the `param_group` for slides.
– When adding the slider in the WPBakery Page Builder, ensure you fill out all fields (image, content, and tab name) for each slide.
2. **Log Debugging Information**:
Modify the shortcode function to log more detailed debugging information. This will help you see exactly what data is being passed and if there are any issues with it. Update your shortcode function as follows:
function custom_slider_shortcode($atts, $content = null) {
// Default attributes
$atts = shortcode_atts([
'slides' => '',
], $atts);
// Log the slides attribute
error_log('Slides attribute: ' . print_r($atts['slides'], true));
// Decode slides into an array
$slides = json_decode($atts['slides'], true);
// Log the decoded slides
error_log('Decoded slides: ' . print_r($slides, true));
// Check if slides are empty
if (empty($slides)) {
return '<div>No slides available.</div>'; // Temporary message for debugging
}
// Generate the slider HTML
ob_start(); ?>
<div class="slider-container">
<div class="slider-wrapper">
<?php foreach ($slides as $index => $slide): ?>
<div class="slide <?php echo $index === 0 ? 'active' : ''; ?>">
<img src="<?php echo esc_url(wp_get_attachment_url($slide['image'])); ?>" alt="<?php echo esc_attr($slide['tab']); ?>" />
<div class="slide-content"><?php echo wp_kses_post($slide['content']); ?></div>
</div>
<?php endforeach; ?>
</div>
<!-- Arrows -->
<div class="slider-controls">
<button class="arrow prev">❮</button>
<button class="arrow next">❯</button>
</div>
<!-- Tabs -->
<div class="slider-tabs">
<?php foreach ($slides as $index => $slide): ?>
<button class="tab <?php echo $index === 0 ? 'active' : ''; ?>" data-index="<?php echo $index; ?>">
<?php echo esc_html($slide['tab']); ?>
</button>
<?php endforeach; ?>
</div>
</div>
<?php
return ob_get_clean();
}
add_shortcode('custom_slider', 'custom_slider_shortcode');
– This will log the raw `slides` attribute and the decoded `slides` array to the WordPress debug log. Make sure WP debugging is enabled by adding or verifying the following lines in your `wp-config.php`:
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false); // Set to false to avoid displaying errors on the front end
3. **Check the Debug Log**:
After adding your slider in WPBakery and viewing the page, check the debug log located in `wp-content/debug.log`. Look for the log entries corresponding to the slides attribute and the decoded slides. This should give you insight into what data is being passed.
4. **Verify the `vc_map` Setup**:
Ensure that the `vc_map` for your custom slider is correctly set up and reflects the expected fields. Here’s the complete example:
add_action('vc_before_init', 'register_custom_slider_element');
function register_custom_slider_element() {
vc_map([
'name' => 'Custom Slider',
'base' => 'custom_slider',
'category' => 'Content',
'params' => [
[
'type' => 'param_group',
'heading' => 'Slides',
'param_name' => 'slides',
'description' => 'Add slides for the slider.',
'params' => [
[
'type' => 'attach_image',
'heading' => 'Slide Image',
'param_name' => 'image',
'description' => 'Upload an image for this slide.',
],
[
'type' => 'textarea_html',
'heading' => 'Slide Content',
'param_name' => 'content',
'description' => 'Enter the content for the slide.',
],
[
'type' => 'textfield',
'heading' => 'Tab Name',
'param_name' => 'tab',
'description' => 'Enter the name for this tab.',
],
],
],
],
]);
}
5. **Manually Test the Shortcode**:
If the logs indicate that the `slides` parameter is empty or malformed, you can manually test the shortcode with a hard-coded slides attribute. Place the following shortcode directly in a post or page:
[custom_slider slides='[{"image": "123", "content": "<p>Slide 1 Content</p>", "tab": "Tab 1"},{"image": "456", "content": "<p>Slide 2 Content</p>", "tab": "Tab 2"}]']
Replace `123` and `456` with actual attachment IDs of images in your media library.
6. **Final Review**:
– **Ensure No Caching Issues**: If you are using any caching plugins, clear the cache to see your latest changes.
– **Check for Errors**: Look at the browser's console for any JavaScript errors that might prevent the slider from functioning properly.
### Summary
By following these steps, you should be able to diagnose why the slides are not appearing. The key points to focus on are the correct configuration in WPBakery, proper data being passed to the shortcode, and logging for deeper insights into the data flow.
If you continue to experience issues, please provide any relevant log entries from `debug.log`, the content of the `vc_map`, and any other information that may help diagnose the problem.
### 1. Update the Shortcode Function
Modify your `custom_slider_shortcode` function to ensure that the image is displayed in full width and the text content is positioned on top of the image.
Here's the revised function:
function custom_slider_shortcode($atts, $content = null) {
// Default attributes
$atts = shortcode_atts([
'slides' => '',
], $atts);
// Decode slides into an array
$slides = json_decode($atts['slides'], true);
// Check if slides are empty
if (empty($slides)) {
return '<div>No slides available.</div>'; // Temporary message for debugging
}
// Generate the slider HTML
ob_start(); ?>
<div class="slider-container">
<div class="slider-wrapper">
<?php foreach ($slides as $index => $slide): ?>
<div class="slide <?php echo $index === 0 ? 'active' : ''; ?>">
<img src="<?php echo esc_url(wp_get_attachment_url($slide['image'])); ?>" alt="<?php echo esc_attr($slide['tab']); ?>" />
<div class="slide-content">
<h2><?php echo esc_html($slide['tab']); ?></h2>
<div><?php echo wp_kses_post($slide['content']); ?></div>
</div>
</div>
<?php endforeach; ?>
</div>
<!-- Arrows -->
<div class="slider-controls">
<button class="arrow prev">❮</button>
<button class="arrow next">❯</button>
</div>
<!-- Tabs -->
<div class="slider-tabs">
<?php foreach ($slides as $index => $slide): ?>
<button class="tab <?php echo $index === 0 ? 'active' : ''; ?>" data-index="<?php echo $index; ?>">
<?php echo esc_html($slide['tab']); ?>
</button>
<?php endforeach; ?>
</div>
</div>
<?php
return ob_get_clean();
}
add_shortcode('custom_slider', 'custom_slider_shortcode');
### 2. Add CSS for Styling
Next, you need to add CSS styles to ensure the images are full-width and the text content is positioned on top. Here’s a sample CSS you can add to your theme’s stylesheet or the custom CSS section of your theme options:
.slider-container {
position: relative;
width: 100%;
overflow: hidden;
}
.slider-wrapper {
display: flex;
transition: transform 0.5s ease;
}
.slide {
position: relative;
flex: 0 0 100%; /* Each slide takes full width */
}
.slide img {
width: 100%;
height: auto; /* Maintain aspect ratio */
display: block; /* Remove extra space below image */
}
.slide-content {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
color: white; /* Change text color */
text-align: center;
background: rgba(0, 0, 0, 0.5); /* Semi-transparent background for better readability */
padding: 20px;
border-radius: 8px;
}
.slider-controls {
position: absolute;
top: 50%;
width: 100%;
display: flex;
justify-content: space-between;
transform: translateY(-50%);
}
.slider-tabs {
display: flex;
justify-content: center;
margin-top: 10px;
}
.tab {
background: #fff; /* Tab background */
border: none;
padding: 10px 20px;
margin: 0 5px;
cursor: pointer;
}
.tab.active {
background: #007bff; /* Active tab color */
color: white; /* Active tab text color */
}
### 3. JavaScript for Slider Functionality
Ensure you have JavaScript functionality to handle the sliding effect when navigating through the images and tabs. You can use a simple jQuery script or plain JavaScript for this purpose. Here’s a basic example:
document.addEventListener('DOMContentLoaded', function() {
const slides = document.querySelectorAll('.slide');
const prevButton = document.querySelector('.arrow.prev');
const nextButton = document.querySelector('.arrow.next');
const tabs = document.querySelectorAll('.tab');
let currentSlide = 0;
function showSlide(index) {
slides.forEach((slide, i) => {
slide.style.display = i === index ? 'block' : 'none';
});
currentSlide = index;
}
nextButton.addEventListener('click', () => {
let nextIndex = (currentSlide + 1) % slides.length;
showSlide(nextIndex);
updateActiveTab(nextIndex);
});
prevButton.addEventListener('click', () => {
let prevIndex = (currentSlide - 1 + slides.length) % slides.length;
showSlide(prevIndex);
updateActiveTab(prevIndex);
});
tabs.forEach((tab, index) => {
tab.addEventListener('click', () => {
showSlide(index);
updateActiveTab(index);
});
});
function updateActiveTab(index) {
tabs.forEach((tab, i) => {
tab.classList.toggle('active', i === index);
});
}
// Initialize
showSlide(currentSlide);
});
### Summary
With these changes, the images in your slider will fill the entire container, and the text content will overlay the images, making it visually appealing and user-friendly.
Make sure to test the implementation on the front end and adjust the CSS styles according to your theme’s design to ensure everything looks great. If you encounter any issues or need further adjustments, feel free to ask!
