How to use manage_this-screen-id_custom_column action in WordPress

manage_this-screen-id_custom_column action

Custom columns are registered using the ‘manage_application-passwords-user_columns’ filter.

To use manage_this-screen-id_custom_column 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 execute_on_manage_this-screen-id_custom_column_event which takes 2 parameters and we registered it using add_action. The first parameter manage_this-screen-id_custom_column is the name of the hook, The second parameter execute_on_manage_this-screen-id_custom_column_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.

Sometimes, you have to remove a registered hook so you can use remove_action to remove manage_this-screen-id_custom_column action.
