How to use admin_head-media-upload-popup action in WordPress

admin_head-media-upload-popup action

Fires when scripts enqueued for the admin header for the legacy (pre-3.5.0) media upload popup are printed.

To use admin_head-media-upload-popup action, first you have to register it using add_action. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

We at WePlugins always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function weplugins_execute_on_admin_head-media-upload-popup_event and we registered it using add_action. The first parameter admin_head-media-upload-popup is the name of the hook, the second parameter weplugins_execute_on_admin_head-media-upload-popup_event is the name of the function which needs to be called, the third parameter is the priority of calling the hook if the same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometime, you have to remove a registered hook so you can use remove_action to remove admin_head-media-upload-popup action.
