Feature Request: Add a filter link for Search-Excluded pages

Replies: 0

Hi,

I would like to make a Feature Request. Basically just a simple filter function. I build an extension that works for me, but it would be nice to have this natively built into the plugin.

Here is the code I used:

<?php
/**
 * Add a filter link for Search-Excluded pages in the admin area
 */
function add_excluded_pages_filter()
{
    // Only run on the pages list screen
    $screen = get_current_screen();
    if ($screen->id !== 'edit-page') {
        return;
    }
 
    // Get the settings from the Search Exclude plugin
    $settings = get_option('qlse_settings', array());
 
    // Check if we have excluded pages
    $excluded_pages = array();
    if (isset($settings['entries']['page']['ids']) && is_array($settings['entries']['page']['ids'])) {
        $excluded_pages = $settings['entries']['page']['ids'];
    }
 
    // Count the excluded pages
    $excluded_count = count($excluded_pages);
 
    // Get the current filter status
    $is_excluded_filter = isset($_GET['search_excluded']) && $_GET['search_excluded'] == '1';
 
    // Only show if there are some excluded pages
    if ($excluded_count > 0) {
        // Inject the link with JavaScript after "Cornerstone-Inhalt (0)"
    ?>
        <script type="text/javascript">
            document.addEventListener('DOMContentLoaded', function() {
                // Create the URL in JavaScript instead of PHP to avoid encoding issues
                var adminUrl = '<?php echo admin_url('edit.php'); ?>';
                var isFiltered = <?php echo $is_excluded_filter ? 'true' : 'false'; ?>;
 
                // Build the URL directly in JavaScript
                var excludedUrl = adminUrl + '?post_type=page';
                if (!isFiltered) {
                    excludedUrl += '&search_excluded=1';
                }
 
                // Find the .subsubsub element
                var subsubsub = document.querySelector('.subsubsub');
                if (subsubsub) {
                    // Create a text node for " | "
                    var separator = document.createTextNode(' | ');
 
                    // Create our excluded link
                    var excludedLink = document.createElement('a');
                    excludedLink.href = excludedUrl;
                    excludedLink.innerHTML = '<?php echo esc_html__('Excluded', 'search-exclude') . ' (' . $excluded_count . ')'; ?>';
                    <?php if ($is_excluded_filter): ?>
                        excludedLink.className = 'current';
                    <?php endif; ?>
 
                    // Append our elements to the end of .subsubsub
                    subsubsub.appendChild(separator);
                    subsubsub.appendChild(excludedLink);
                }
            });
        </script>
<?php
    }
}
add_action('restrict_manage_posts', 'add_excluded_pages_filter', 100);
 
/**
 * Modify the query when the excluded filter is selected
 */
function filter_pages_by_search_excluded($query)
{
    // Only run on admin page listings
    if (!is_admin() || !$query->is_main_query()) {
        return;
    }
 
    // Make sure we're on the pages screen
    $screen = get_current_screen();
    if (!$screen || $screen->id !== 'edit-page') {
        return;
    }
 
    // Check if our filter is active
    if (isset($_GET['search_excluded']) && $_GET['search_excluded'] == '1') {
        // Get the settings from the Search Exclude plugin
        $settings = get_option('qlse_settings', array());
 
        // Get excluded page IDs - access the correct structure
        $excluded_pages = array();
        if (isset($settings['entries']['page']['ids']) && is_array($settings['entries']['page']['ids'])) {
            $excluded_pages = $settings['entries']['page']['ids'];
        }
 
        // Make sure we have excluded pages to filter
        if (!empty($excluded_pages)) {
            // Set the post__in parameter to show only excluded pages
            $query->set('post__in', $excluded_pages);
        } else {
            // If no pages are excluded but the filter is active, show no results
            $query->set('post__in', array(0)); // This will return no posts
        }
    }
}
add_action('pre_get_posts', 'filter_pages_by_search_excluded', 10);

Result:
