WP_Ajax & Namespaces

I’m trying to make use of WP_Ajax but having problems while testing and I think it could be related to the functions Namespace. Pointers are really appreciated. Maybe is just that I’m lost…

The $.ajax call is returning 0.

What I don’t know is if the function is actually being called.
If that was the case, how would I call the function for its namespace on js within data : {action: 'action_name'} ?

Ajax call:

$.ajax({
	url : wpadmin.adminAjax,
	data : {
		action: 'action_name'
	},
	success: function(response) {
		console.log(response);
	}
});

Function:

add_action( 'wp_ajax_action_name', __NAMESPACE__ . '\\action_name' );
add_action( 'wp_ajax_nopriv_action_name', __NAMESPACE__ . '\\action_name' );
function action_name() {
    return 'stuff';
    die();
}

Nothing to do with Namespaces, the function it’s being called but it should echo instead of return for the purpose of this test.

add_action( 'wp_ajax_action_name', __NAMESPACE__ . '\\action_name_callback' );
add_action( 'wp_ajax_nopriv_action_name', __NAMESPACE__ . '\\action_name_callback' );
function action_name_callback() {
    echo 'stuff';
    die();
}

Thanks for following up with your own solution. It makes maintaining the forum so much easier. :thumbsup:

you have to call admin-ajax.php but which path did you use?

  function my_enqueue() {
    wp_enqueue_script( 'ajax-script', get_template_directory_uri() . '/assets/scripts/main.js', array('jquery') );
    wp_localize_script( 'ajax-script', 'my_ajax_object',
      array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) );
  }
  add_action( 'wp_enqueue_scripts', __NAMESPACE__ .'\\my_enqueue' );

I find the way to do it, you have to open Ajax in setup.php

function my_enqueue() {
  wp_enqueue_script('sage/js', Assets\asset_path('scripts/main.js'), ['jquery'], null, true);
  wp_localize_script( 'sage/js', 'my_ajax_object',
    array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) );
}
add_action( 'wp_enqueue_scripts', __NAMESPACE__ .'\\my_enqueue' );
