How to use deprecated_argument_trigger_error filter in WordPress

To use the deprecated_argument_trigger_error filter, you first need to register it with add_filter. You can place this code in the functions.php file of your active theme or, even better, in a custom WordPress Plugin. At WePlugins, we always recommend creating a custom plugin to ensure your changes remain intact during theme updates.

Here’s a quick look at the parameter involved:

• $trigger: (bool) Whether to trigger the error for deprecated arguments. Default is true.

Now, let’s see some live examples to get a clearer picture.

Example 1: Applying the Filter

This example shows how to apply the filter.

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

Example 2: Removing the Filter

If you need to remove this hook, you can do so with the following code.

    remove_filter( "deprecated_argument_trigger_error", "weplugins_modify_deprecated_argument_trigger_error_defaults", 10, 1 );
    

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

Example 3: Conditional Logic with the Hook

You can also apply conditional logic to decide when to trigger the error.

    function weplugins_conditional_trigger($trigger) {
        if(some_condition()) {
            $trigger = false; // Prevent error trigger based on a condition
        }
        return $trigger;
    }
    add_filter("deprecated_argument_trigger_error", "weplugins_conditional_trigger", 10, 1);
