    Hi, I have the following ajax call that does not return a value when I add it in my snippet.

    $.ajax({
    url: ‘/wp-content/themes/astra/functions.php’,
    type: ‘POST’,
    data: {data_x: 4},
    success: function(data) {
    alert(‘yes’);
    alert(data);
    }
    });

    Alert yes does work but alert data doesn’t it is just blank. Here is the code where I send it to in the same snippet at the very top of the snippet.

    if (isset($_POST[‘data_x’])) {
    echo ‘hallo’;
    }

    So if everything is working, alert data should return hallo. I suspect that the ajax url is incorrect but I have no idea where else to send the call to or where the snippet saves the code. Please help!

    You can use admin_url( 'admin-ajax.php' ) to find the AJAX url using PHP, or if this code is running in the admin area then you can use the built-in ajaxurl variable:

    $.ajax({
    url: ajaxurl,
    type: 'POST',
    ....

    Hi

    I have tried that, but lo luck, alert yes and alert data doesn’t return any values. Here is the code.

    $.ajax({
                        url: '<?php echo admin_url('admin-ajax.php') ?>',
                        type: 'POST',
                        data: {
                            quantity: quantity,
                            action: 'dynamic_price'
                        },
                        success: function(data) {
                            //var price = data;
                            alert('yes');
                            alert(data);
                        }
                    });

    You should use wp_send_json_success to send the price back to your script instead of just echoing it.

    Will you be able to send me an example please, never used it before.

    instead of

    echo $price;

    you should use:

    wp_send_json_success( $price );

    Still did not work, even alert yes does not work. Usually alert yes works, good indication that ajax is working but in this case alert yes does not work. Is there maybe a test that we can do to see if ajax is working fine and the path is correct?
