How to use do_redirect_guess_404_permalink filter in WordPress

do_redirect_guess_404_permalink filter

So, you’re diving into WordPress hooks, eh? Well, the do_redirect_guess_404_permalink filter is one you might find pretty handy. This filter is all about whether WordPress should try to guess a redirect URL when a 404 error pops up. If you return false from this filter, it simply stops the URL guessing game and doesn’t perform a redirect. Nice and simple, right?

To get this filter working, you need to register it using add_filter. Now, you can throw this bit of code into the functions.php file of your active theme or, better yet, in a custom WordPress Plugin. At WePlugins, we always suggest creating a custom plugin for this kind of stuff. That way, when you update your WordPress theme, everything stays intact.

And hey, if you ever need to remove a registered hook, remove_filter is your friend.

Live Example 1: Modifying the Default Behavior

            // You can modify the $do_redirect_guess variable conditionally too if you want.
            return $do_redirect_guess; 
        }
        // add the filter
        add_filter( "do_redirect_guess_404_permalink", "weplugins_modify_do_redirect_guess_404_permalink_defaults", 10, 1 );
