How to use network_by_path_segments_count filter in WordPress

Hey there! If you’re diving into WordPress development, you might have come across hooks. These little pieces of magic allow you to customize and extend WordPress without hacking core files. Today, we’re talking about the network_by_path_segments_count filter. It’s a handy tool when you need to control how many path segments WordPress should consider when searching for a site. Let’s break it down with some examples.

Example 1: Basic Usage of network_by_path_segments_count

To use the network_by_path_segments_count filter, you need to register it with add_filter. Place this code in your theme’s functions.php file or a custom plugin. Here, we’ll modify how many path segments are considered. Check it out:

    function weplugins_modify_network_by_path_segments_count($segments, $domain, $path) { 
        // Customize the $segments variable as needed.
        return $segments; 
    }
    // Add the filter
    add_filter("network_by_path_segments_count", "weplugins_modify_network_by_path_segments_count", 10, 3);
    

Example 2: Conditional Modification

Sometimes, you might want to change the number of path segments based on certain conditions. Here’s how you can do it:

    function weplugins_conditional_network_by_path_segments_count($segments, $domain, $path) { 
        if ($domain == 'example.com') {
            $segments = 2; // Example condition
        }
        return $segments;
    }
    // Add the filter
    add_filter("network_by_path_segments_count", "weplugins_conditional_network_by_path_segments_count", 10, 3);
    

Example 3: Removing the Hook

If you need to remove a filter, use remove_filter. Just ensure you use the same function name, priority, and number of arguments as when you added it.

    // Remove the filter
    remove_filter("network_by_path_segments_count", "weplugins_modify_network_by_path_segments_count", 10, 3);
