wp_send_json_success WordPress function

Function Name: wp_send_json_success

If you want to send a JSON response to an AJAX request, then wp_send_json_success() function is a great option. This function packs the data you want to send into a JSON object and sends it back, along with a ‘success’ flag to indicate that the request was successful.

This function is used to send an AJAX response containing a JSON success message with arbitrary data, and then terminates execution by calling wp_die(). By default, it returns a 200 response code, but you can change it if you need to.

Here’s an example usage code:

function my_ajax_function() {
  // perform some action here
  $data = array(
    'message' => 'Success!',
    'data'    => array(
      'name'    => 'John Doe',
      'email'   => 'johndoe@email.com',
      'phone'   => '555-555-5555'
    )
  );
  wp_send_json_success($data);
}
add_action('wp_ajax_my_ajax_function', 'my_ajax_function');

In this example, we define a function that performs some action and creates a data array. We then pass this array to wp_send_json_success() function, which sends back a JSON success message with the data array. This function can be used in any AJAX request where you need to send back JSON data.
