How to use deprecated_file_trigger_error filter in WordPress

When working with WordPress, you’ll often come across various hooks that can be a bit confusing at first. But don’t worry, with a bit of practice, you’ll be using them like a pro! Today, we’ll dive into the deprecated_file_trigger_error filter. It’s used to control whether an error should be triggered for deprecated files. Let’s explore this hook and see how it can be implemented in your WordPress site.

Example 1: Modifying the Default Trigger

In this example, we will define a function that modifies the default behavior of the deprecated_file_trigger_error hook. You can adjust the $trigger variable according to your requirements.

    function weplugins_modify_deprecated_file_trigger_error_defaults($trigger) { 
        // Update the $trigger variable according to your website requirements.
        return $trigger; 
    }
    // add the filter
    add_filter( "deprecated_file_trigger_error", "weplugins_modify_deprecated_file_trigger_error_defaults", 10, 1 );
    

Example 2: Removing the Hook Callback

Sometimes, you might need to remove a registered hook. Here’s how you can use remove_filter to remove the deprecated_file_trigger_error filter.

    remove_filter( "deprecated_file_trigger_error", "weplugins_modify_deprecated_file_trigger_error_defaults", 10, 1 );
    

Ensure you provide the same callback function name, priority, and number of arguments when removing the hook callback.

Example 3: Applying the Filter

Below is how you can apply the deprecated_file_trigger_error filter. This example demonstrates the basic use of the hook.

    apply_filters( 'deprecated_file_trigger_error', bool $trigger )
