Also thank you for your explanation regarding the use of Classes and how to call the functions inside them. Again, you saved my day! | |

When I use $this->loader->add_action( 'wp_ajax_myplugin_ajax_function', $plugin_admin, 'myplugin_ajax_function' ); I get a 500 error on the admin-ajax.php file in the console. When I use $this->loader->add_action( 'wp_ajax_myplugin_ajax_function, 'wp_ajax', array( $plugin_admin, 'myplugin_ajax_function' ) ); I get the same result (0) as I did before.

Or use $this->loader->add_action( 'wp_ajax_myplugin_ajax_function', $plugin_admin, 'myplugin_ajax_function' ); ? (note the 2nd parameter)

Actually, there were 2 issues in your original code in question - 1) the AJAX action, and 2) the AJAX callback (the 3rd parameter for $this->loader->add_action()); and now you've corrected the 1st issue, but the 2nd one is still there - use array( $plugin_admin, 'myplugin_ajax_function' ) like in my answer, and not just 'myplugin_ajax_function'. Or was that also another typo in the question only? 🤔

| Jul 12, 2022 at 12:16 | comment | added | DeltaG | Yes, you are right about that mistake. Thanks for pointing it out. I think I've copied it wrongly in here, in my live code it was indeed the function name instead of the name of the script. I've updated my question with the correct action name. | |
