Form Submission Issues
### Possible Issues:
1. **Flush Buffer and Die Before Processing**: You're using `print_r($_POST); die;` which stops execution. This means your form isn't reaching the `wp_redirect()` part, thus causing a potential "Page Not Found" if your form is re-submitted.
2. **Redirection Issue**: The URL for redirection might not be set up correctly. WordPress's `wp_redirect()` function requires a proper URL, and sometimes `add_query_arg()` may not work as expected if not used properly.
3. **Email Address Undefined**: The `$email` variable is being used without being defined. This can cause errors when checking if the email exists.
4. **Nonce Verification**: If the nonce check fails, you're not redirecting or displaying any errors properly, which might also result in a blank or error page.
### Updated Code:
Here's a refactored version of your shortcode function:
<?php
add_shortcode('provider_add_listing', 'alaphasia_listing_form_shortcode');
function alaphasia_listing_form_shortcode() {
ob_start(); // Start output buffering
$message = '';
$listing_data = isset($_POST['add_listing_create_account']) ? $_POST : array(); // Retain submitted data for pre-filling
if ($_SERVER['REQUEST_METHOD'] === 'POST' && isset($_POST['add_listing_create_account'])) {
// Recaptcha Secret Key
$secretKey = '6LfO3YAqAAAAAF4f8GEpwu0Jh0-C3gRbA27Uvh2v';
if (isset($_POST['provider_add_listing_action_nonce'])) {
$nonce = $_POST['provider_add_listing_action_nonce'];
// Verify the nonce and make sure it's valid
if (wp_verify_nonce($nonce, 'provider_add_listing_action')) {
if (isset($_POST['g-recaptcha-response'])) {
$recaptcha_response = sanitize_text_field($_POST['g-recaptcha-response']);
$response = wp_remote_post('https://www.google.com/recaptcha/api/siteverify', [
'body' => [
'secret' => $secretKey,
'response' => $recaptcha_response,
'remoteip' => $_SERVER['REMOTE_ADDR'], // Optional: User's IP address
],
]);
if (is_wp_error($response)) {
$message = __('reCAPTCHA request failed.', '');
} else {
$response_body = wp_remote_retrieve_body($response);
$result = json_decode($response_body, true);
if (isset($result['success']) && $result['success']) {
// Define email properly
$email = sanitize_email($_POST['email']);
// Check if email exists
if (email_exists($email)) {
$message = __('This email has already been taken. Please register with another email.', '');
} else {
// Insert the post data
$post_data = array(
'post_title' => 'Provider submit application',
'post_content' => serialize($_POST),
'post_type' => 'apply_lising_front',
'post_status' => 'pending', // Set to pending for approval
);
$post_id = wp_insert_post($post_data);
// Send confirmation email to user
$subject_user = __('Thank You for Applying to List Your Services', '');
$message_user = "
<p>Dear " . sanitize_text_field($_POST['first_name']) . ",</p>
<p>Thanks for applying to list your services with the <strong>National Aphasia Association</strong>! We're reviewing your application and will notify you if it's approved.</p>
<p>Best regards,</p>
<p>The National Aphasia Association</p>";
$headers = array('Content-Type: text/html; charset=UTF-8');
wp_mail($email, $subject_user, $message_user, $headers);
// Send notification email to admin
$subject_admin = __('New Application For Provider Services', '');
$message_admin = "
<p>Dear Admin,</p>
<p>There is a new application for provider service. Please review it in your admin console.</p>
<p>Best regards,</p>
<p>The National Aphasia Association</p>";
wp_mail(get_option('admin_email'), $subject_admin, $message_admin, $headers);
// Redirect after successful submission
$current_url = home_url(add_query_arg(array(), $_SERVER['REQUEST_URI']));
$redirect_url = add_query_arg('submission', 'success', $current_url);
wp_safe_redirect($redirect_url);
exit;
}
} else {
$message = __('Recaptcha validation failed.', '');
}
}
} else {
$message = __('Recaptcha response missing.', '');
}
} else {
$message = __('You are unauthorized to perform this action.', '');
}
}
}
// Include the form template
$form_template = get_stylesheet_directory() . '/templates/custom-listing-form.php';
if (file_exists($form_template)) {
include($form_template);
} else {
echo '<p>Form template not found.</p>';
}
if (!empty($message)) {
echo '<div class="form-message">' . esc_html($message) . '</div>';
}
return ob_get_clean(); // Return the buffered content
}### Key Changes:
1. **Removed `print_r()` and `die` statements**: These were stopping the form processing.
2. **Defined `$email`**: Ensured the `$email` variable is defined correctly.
3. **Added `wp_safe_redirect()`**: More secure redirection.
4. **Handled error messages gracefully**: Displayed any issues as part of the form output.
5. **Proper Sanitization**: Ensured all user inputs are sanitized before usage.
Try using this updated code and see if it resolves the "Page Not Found" issue. Make sure to clear your WordPress cache if you're using any caching plugins.

### Possible Issues
1. **Form Method Mismatch**: The form might not be using the `POST` method.
2. **Incorrect Form Field Names**: The `name` attribute for your form fields might not match what you are checking in PHP.
3. **Form Action Attribute**: The form's `action` attribute might not be set correctly.
4. **WordPress Caching/Nonce**: Caching or nonce issues could prevent form submission data from being recognized.
### Debugging Steps
1. **Check HTML Form**: Ensure your form is using the correct method and field names.
2. **Print `$_POST` Array**: Add debugging code to check if any data is being submitted.
### Sample Form HTML
Make sure your form looks something like this:
<form method="POST" action="">
<?php wp_nonce_field('provider_add_listing_action', 'provider_add_listing_action_nonce'); ?>
<input type="text" name="first_name" placeholder="First Name" required>
<input type="email" name="email" placeholder="Email" required>
<!-- Add the hidden field to indicate the form was submitted -->
<input type="hidden" name="add_listing_create_account" value="1">
<!-- reCAPTCHA widget -->
<div class="g-recaptcha" data-sitekey="your-site-key"></div>
<button type="submit">Submit</button>
</form>### Add Debugging Code
Before the `if` statement, add a debugging print to see what data is coming in:
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
echo '<pre>';
print_r($_POST);
echo '</pre>';
die;
}### Things to Check
1. **Ensure Form Fields Are Correct**: Verify that your form field names (`add_listing_create_account`, `provider_add_listing_action_nonce`, etc.) match exactly what you are checking in your PHP code.
2. **reCAPTCHA Script**: Make sure the reCAPTCHA widget is properly loaded by including this in your “:
<script src="https://www.google.com/recaptcha/api.js" async defer></script>3. **Disable Caching**: If you have a caching plugin enabled, clear the cache or temporarily disable it to ensure it's not interfering with your form submission.
### Revised PHP Code
To handle the debugging and ensure everything is set correctly:
add_shortcode('provider_add_listing', 'alaphasia_listing_form_shortcode');
function alaphasia_listing_form_shortcode() {
ob_start();
$message = '';
// Debugging: Check if data is being posted
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
echo '<pre>$_POST data: ';
print_r($_POST);
echo '</pre>';
}
if ($_SERVER['REQUEST_METHOD'] === 'POST' && isset($_POST['add_listing_create_account'])) {
echo '<p>Form submission detected!</p>'; // Debugging line
$secretKey = '6LfO3YAqAAAAAF4f8GEpwu0Jh0-C3gRbA27Uvh2v';
if (isset($_POST['provider_add_listing_action_nonce'])) {
$nonce = $_POST['provider_add_listing_action_nonce'];
if (wp_verify_nonce($nonce, 'provider_add_listing_action')) {
// Continue your processing
$message = 'Form processed successfully.';
} else {
$message = 'Invalid nonce.';
}
} else {
$message = 'Nonce not set.';
}
}
// Display the message if set
if (!empty($message)) {
echo '<div class="form-message">' . esc_html($message) . '</div>';
}
$form_template = get_stylesheet_directory() . '/templates/custom-listing-form.php';
if (file_exists($form_template)) {
include($form_template);
} else {
echo '<p>Form template not found.</p>';
}
return ob_get_clean();
}### Try This:
– Ensure the `form` HTML is correct.
– Use the debugging lines to see what's being captured in the `$_POST` array.
– Adjust your PHP code based on the debugging output.
This should help you pinpoint why your form submission is not reaching the expected condition.
