How to use doing_it_wrong_trigger_error filter in WordPress

doing_it_wrong_trigger_error filter

Filters whether to trigger an error for _doing_it_wrong() calls.

To use the doing_it_wrong_trigger_error filter, first you need to register it using add_filter. You can place this code into the functions.php of your activated theme or in a custom WordPress Plugin. WePlugins always prefer creating a custom WordPress Plugin while using hooks, so nothing breaks when you update your WordPress Theme in the future.

In the example below, we’ve defined a function weplugins_modify_doing_it_wrong_trigger_error_defaults which takes 4 parameters and is registered using add_filter. The first parameter doing_it_wrong_trigger_error is the name of the hook, the second parameter is the name of the function 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 need to remove a registered hook, so you can use remove_filter to remove doing_it_wrong_trigger_error filter.

Parameters

Below are the 4 parameters required to use this hook.

• $trigger : (bool) Whether to trigger the error for _doing_it_wrong() calls. Default true.
• $function : (string) The function that was called.

            $trigger = false;
        }
        return $trigger;
    }
    add_filter( "doing_it_wrong_trigger_error", "weplugins_modify_doing_it_wrong_conditionally", 10, 4 );
