通过Ajax获取短代码值 - wordpress

Question

I'm new in wordpress and I don't know two much about this.

Situation There is plugin that generate shortcode [unread_messages].
plugin path is wp-content/plugin/chat/ I create a php file under wp-content/custom/messages.php

messages.php

 <?php

  echo do_shortcode('[unread_messages]');

 ?>

And I call request through AJAX like providing url wp-content/custom/messages.php But this php file gives an error call undefined function do_shortcode

How can I access the value of shortcode through which is not a part of plugin.

You Can't get call AJAX call like this first you need to register AJAX call and then send request to admin-ajax.php

Check out this.

add_action('wp_ajax_nopriv_unread_messages', 'unread_messages');
add_action('wp_ajax_unread_messages', 'unread_messages');
function unread_messages(){
        $output['response'] = do_shortcode('[unread_messages]');
        wp_send_json( $output );
}   

After then call AJAX like this.

jQuery.ajax({
        url : 'yourwebsite/wp-admin/admin-ajax.php',
        type : 'post',
        data : {
            action : 'unread_messages'
        },
        success : function( response ) {

        }
    });
