How to use list_pages filter in WordPress

Example 1: Basic Usage of list_pages Filter

Here’s a basic example demonstrating how to use the list_pages filter to modify the page title.

    function weplugins_modify_list_pages_defaults($title, $page) { 
        // Update the $title variable according to your website requirements.
        return $title; 
    }
    // add the filter
    add_filter("list_pages", "weplugins_modify_list_pages_defaults", 10, 2);
    

Example 2: Conditional Title Modification

In this example, we show how you can modify the $title conditionally based on the page data.

    function weplugins_conditional_modify_list_pages($title, $page) { 
        if ($page->ID == 42) { // Just an example condition
            $title .= ' - Special Page';
        }
        return $title; 
    }
    add_filter("list_pages", "weplugins_conditional_modify_list_pages", 10, 2);
    

Example 3: Removing the filter

There might be scenarios where you need to remove a registered hook. Here’s how you can do it.

    remove_filter("list_pages", "weplugins_modify_list_pages_defaults", 10, 2);
    

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