To properly call an AJAX URL in WordPress, follow these steps:
- Register your AJAX action in the theme's functions.php file or in a custom plugin. Use the wp_ajax_{action} for logged-in users and wp_ajax_nopriv_{action} for non-logged-in users. Here's an example:
1 2 3 4 5 6 7 8 |
add_action( 'wp_ajax_my_ajax_action', 'my_ajax_function' );
add_action( 'wp_ajax_nopriv_my_ajax_action', 'my_ajax_function' );
function my_ajax_function() {
// Handle AJAX request
wp_send_json_success( 'Success!' );
wp_die();
}
|
- Enqueue the AJAX script in your theme's functions.php file or in a custom plugin. This makes sure WordPress is aware of the AJAX request. For example:
1 2 3 4 5 |
function enqueue_ajax_scripts() {
wp_enqueue_script( 'my_script', get_stylesheet_directory_uri() . '/js/my_script.js', array( 'jquery' ), '1.0', true );
wp_localize_script( 'my_script', 'ajax_object', array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) );
}
add_action( 'wp_enqueue_scripts', 'enqueue_ajax_scripts' );
|
- Create a JavaScript file, my_script.js, in your theme or plugin folder. Here's an example of how to make an AJAX call:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
jQuery(document).ready(function($) {
$('#my-button').click(function(e) {
e.preventDefault();
$.ajax({
type: 'POST',
url: ajax_object.ajax_url,
data: {
action: 'my_ajax_action'
},
success: function(response) {
console.log(response);
},
error: function(errorThrown) {
console.log(errorThrown);
}
});
});
});
|
- Lastly, create the element triggering the AJAX call in your theme or plugin template file. For example:
1
|
<a href="#" id="my-button">Send AJAX Request</a> |
This setup ensures that when the button with ID my-button is clicked, it triggers the AJAX request to the registered AJAX action my_ajax_action, which then executes the callback function my_ajax_function.
