Hook for URL Request

Actually, my recommendation would be to do things a bit differently. You can add a custom rewrite endpoint to WordPress to handle these files specifically. For example, the URL http://site.com/download-xml/the_filename would automatically download the specified file as an attachment. First, you need to add a custom rewrite endpoint to set this up: function add_endpoint() { … Read more

Send data to 3rd party api with wp_remote_post on wp_login

The ‘body’ needs to be an array, not including the ‘json_encode($user)’ piece. $response = wp_remote_post( ‘myapp.com/endpoint’, array( ‘method’ => ‘POST’, ‘headers’ => array(‘Content-Type’ => ‘application/json; charset=utf-8’), ‘body’ => $user ) ); I have this in my function since I also had issues with the body being an object: if (is_object($user) && !is_array($user)) $user = json_decode(json_encode($user), … Read more

How to check if which hook triggered the call to a function?

I found the magic code you need. Use current_filter(). This function will return name of the current filter or action. add_action(‘my_test_hook_1′,’my_test_callback_function’); add_action(‘my_test_hook_2′,’my_test_callback_function’); add_action(‘my_test_hook_3′,’my_test_callback_function’); add_action(‘my_test_hook_4′,’my_test_callback_function’); function my_test_callback_function(){ $called_action_hook = current_filter(); // ***The magic code that will return the last called action echo “This function is called by action: ” . $called_action_hook ; } For reference: https://developer.wordpress.org/reference/functions/current_filter/
