Display ACF Field Below Post
Here's how you can achieve that:
1. **Using `the_content` filter**:
This approach will append the ACF field below the post content.
function display_acf_field_below_post_content($content) {
// Check if we're on a single post and a custom post type
if (is_singular('your_custom_post_type')) {
// Get the ACF field value (change 'your_acf_field' to your actual field name)
$acf_field_value = get_field('your_acf_field');
// Append the ACF field value to the content
if ($acf_field_value) {
$content .= '<div class="acf-field">' . esc_html($acf_field_value) . '</div>';
}
}
return $content;
}
add_filter('the_content', 'display_acf_field_below_post_content');This code will display the ACF field value below the post content in single custom post type pages. Make sure to replace `'your_acf_field'` with the actual field name you created in ACF.
2. **Using `wp_footer` or custom action hooks**:
If you need more control or want to display the ACF field in a specific area within the HTML structure (e.g., below the post details), you can use an action hook like `wp_footer` or define a custom hook in your theme:
function display_acf_field_below_post_content_action() {
if (is_singular('your_custom_post_type')) {
$acf_field_value = get_field('your_acf_field');
if ($acf_field_value) {
echo '<div class="acf-field">' . esc_html($acf_field_value) . '</div>';
}
}
}
add_action('wp_footer', 'display_acf_field_below_post_content_action');You can replace `wp_footer` with any other hook based on your theme structure or desired location (e.g., `the_content`, `loop_end`, or custom hooks).
### Method 1: Using `the_content` Filter (to prepend the ACF field before the content)
You can use the `the_content` filter to prepend the ACF field above the post content.
function display_acf_field_above_post_content($content) {
// Check if we're on a single post and a custom post type
if (is_singular('your_custom_post_type')) {
// Get the ACF field value (replace 'your_acf_field' with the actual field name)
$acf_field_value = get_field('your_acf_field');
// Prepend the ACF field value before the content
if ($acf_field_value) {
$content = '<div class="acf-field">' . esc_html($acf_field_value) . '</div>' . $content;
}
}
return $content;
}
add_filter('the_content', 'display_acf_field_above_post_content');### Method 2: Using Action Hook (for more flexibility)
You can also use an action hook to place the ACF field before the content. The `the_content` hook can be used if you want to output content in specific places like above the post content.
If your theme has a specific hook before the content starts, you can hook into it. Here's how to do it with a custom hook or `wp_head`:
function display_acf_field_above_post_content_action() {
if (is_singular('your_custom_post_type')) {
$acf_field_value = get_field('your_acf_field');
if ($acf_field_value) {
echo '<div class="acf-field">' . esc_html($acf_field_value) . '</div>';
}
}
}
// Use a hook before the content (depending on your theme, this could vary)
add_action('the_content', 'display_acf_field_above_post_content_action', 5); // Use priority to control orderIn both methods, make sure to replace `'your_acf_field'` with the actual field name you created in ACF.
Here's how you can retrieve and display both the custom post field and the ACF option field:
### Method 1: Using `the_content` Filter (to prepend both fields)
This method will prepend both your custom post ACF field and the ACF option field before the post content.
function display_acf_fields_above_post_content($content) {
// Check if we're on a single post and a custom post type
if (is_singular('your_custom_post_type')) {
// Get the custom post ACF field (replace 'your_acf_field' with your actual field name)
$acf_post_field_value = get_field('your_acf_field');
// Get the ACF option field (replace 'your_acf_option_field' with the option field name)
$acf_option_field_value = get_field('your_acf_option_field', 'option');
// Prepend both ACF field values before the content
$output = '';
if ($acf_option_field_value) {
$output .= '<div class="acf-option-field">' . esc_html($acf_option_field_value) . '</div>';
}
if ($acf_post_field_value) {
$output .= '<div class="acf-post-field">' . esc_html($acf_post_field_value) . '</div>';
}
// Prepend the fields to the content
$content = $output . $content;
}
return $content;
}
add_filter('the_content', 'display_acf_fields_above_post_content');### Method 2: Using Action Hook (for more control)
This method allows more flexibility and control by using an action hook. It will display both the custom post ACF field and the ACF option field before the content.
function display_acf_fields_above_post_content_action() {
if (is_singular('your_custom_post_type')) {
// Get the custom post ACF field
$acf_post_field_value = get_field('your_acf_field');
// Get the ACF option field
$acf_option_field_value = get_field('your_acf_option_field', 'option');
// Output the fields above the content
if ($acf_option_field_value) {
echo '<div class="acf-option-field">' . esc_html($acf_option_field_value) . '</div>';
}
if ($acf_post_field_value) {
echo '<div class="acf-post-field">' . esc_html($acf_post_field_value) . '</div>';
}
}
}
// Use a hook before the content (depends on theme structure)
add_action('wp_before_main_content', 'display_acf_fields_above_post_content_action'); // Adjust hook as needed### Explanation:
– **Custom Post ACF Field**: `get_field('your_acf_field')` retrieves the ACF field for the current custom post.
– **ACF Option Field**: `get_field('your_acf_option_field', 'option')` retrieves the ACF field from the ACF options page (make sure to replace `'your_acf_option_field'` with the actual field name you created in the options page).
The above code prepends both fields to the content, ensuring the option field is displayed above the post content. Adjust the hook (`wp_before_main_content`) based on your theme structure for the action hook method.
This is a radio also want value with option name
### Explanation:
– `get_field('virtual_or_in_person')`: This will return the selected value (the key of the selected option).
– `get_field_object('virtual_or_in_person')`: This will return the field object, which contains all the choices and labels.
– You can then match the selected value to get the label (option name) of the radio button.
Here is how you can achieve this:
### Example Code:
function display_acf_radio_value_and_label($content) {
// Check if we're on a single post and a custom post type
if (is_singular('your_custom_post_type')) {
// Get the ACF radio button field value (this will return the selected value, e.g., 'virtual' or 'in_person')
$acf_field_value = get_field('virtual_or_in_person');
// Get the ACF field object to get the choices
$field_object = get_field_object('virtual_or_in_person');
// Get the label based on the selected value
$acf_field_label = '';
if ($acf_field_value && isset($field_object['choices'][$acf_field_value])) {
$acf_field_label = $field_object['choices'][$acf_field_value];
}
// Prepare the output to prepend to the content
$output = '';
if ($acf_field_value && $acf_field_label) {
$output .= '<div class="acf-radio-field">';
$output .= '<strong>Selected Option:</strong> ' . esc_html($acf_field_label) . ' (' . esc_html($acf_field_value) . ')';
$output .= '</div>';
}
// Prepend the radio button field value and label to the content
$content = $output . $content;
}
return $content;
}
add_filter('the_content', 'display_acf_radio_value_and_label');### Explanation of the code:
1. **`get_field('virtual_or_in_person')`**: This retrieves the selected value of the radio button (e.g., `'virtual'` or `'in_person'`).
2. **`get_field_object('virtual_or_in_person')`**: This gets the full field object, which includes all the available choices for the radio button.
3. **Matching the selected value to the label**: We use the selected value (`$acf_field_value`) to find the corresponding label from the `choices` array of the field object.
4. **Display**: We display both the selected value and its corresponding label in the output.
Now, when the post is viewed, the selected radio button value and its corresponding label (option name) will appear above the content.
### Example Output:
If the value selected for `virtual_or_in_person` is `'virtual'`:
Selected Option: Virtual (virtual)If you want to modify the output further (e.g., show more formatting), you can customize the HTML structure inside the `output` variable.
