Plugin Accepting Ajax?

Hello,

would you please be more specific about how exactly are you “trying to run this with ajax”? You can also share the custom code you’re trying to add with the plugin and is related to “trying to run this with ajax”.

On the first sight that code should work alright.

There is one small error that might break the code: the ‘ajax-script’ code is localized under the “my_ajax_object” variable, but the JS code tries to send the POST data to the “cu_ajax_object.ajax_url” URL instead of “my_ajax_object.ajax_url”.

Also, the hook name in the first “add_action” function call is named “wp_ajax_my_action_hook” instead of “wp_ajax_my_ajax_hook”.

The following works alright on my side:

jQuery(document).ready(function($){
    $('.filter-option').change(function() {
      $.ajax({
        url: cu_ajax_object.ajax_url,
        type: 'POST',
        data: {
            post_details : 'abc',
            action: 'my_action_hook'
        },
        error: function(error) {
                console.log('error', error);
        },
        success: function(response) {
                console.log( 'success', response );
        }
    });
  });
}); 

and

add_action('wp_ajax_my_action_hook', 'my_function');
add_action('wp_ajax_nopriv_my_action_hook', 'my_function');

add_action( 'wp_enqueue_scripts', 'my_enqueue' );
function my_enqueue() {
    $upload_dir = wp_upload_dir();
    wp_enqueue_script( 'ajax-script', $upload_dir['baseurl'] . '/custom-css-js/152152.js', array('jquery') );
    wp_localize_script( 'ajax-script', 'cu_ajax_object',
            array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) );
}

function my_function() {
    wp_send_json( 'return from the AJAX' );
    wp_die();
}

Please copy/paste the code snippets exactly and see if you get an answer from the server. Afterwards you can fill in the my_function() function and the “data” method of the AJAX object, so you can send the degreetype, areainterest, programlocation variables

Would you move the PHP snippet in the theme’s functions.php file and the JS simply added at the end of one of the theme’s JS files? If you’re still getting the 400 error, then it’s not because of the Code Snippets or the Simple Custom CSS and JS plugin, but it’s because of the actual code.

I cannot debug your code at the distance. And obviously it was harboring enough errors to begin with. Once you get the code working alright directly from the theme, then you can try moving it in the Code Snippets and the Simple Custom CSS and JS plugins and see if you get additional issues there.

On my test website last snippets work alright. So the short answer to your initial questions is: yes, the plugin accepts AJAX. But only under the assumption that the JS/PHP code is correct.
