Customize URLs Automatically Purged by FlyingPress

When you publish, update, or delete content, FlyingPress automatically purges the affected pages to ensure fresh content is served. You can modify this behavior using the flying_press_auto_purge_urls filter to add or remove URLs from the auto-purge list.

Where to add this code

You can place the filter in:

Your theme’s functions.php file
A custom plugin
A plugin like Code Snippets

Example: Add custom URLs to the purge list

add_filter('flying_press_auto_purge_urls', function ($urls, $post_id) {
    $urls[] = 'https://example.com/your-page/';
    $urls[] = 'https://example.com/another-related-page/';
    return $urls;
}, 10, 2);

This ensures additional URLs are purged when the specified post is updated.

Example: Remove URLs from the purge list

add_filter('flying_press_auto_purge_urls', function ($urls, $post_id) {
    $remove_urls = [
        'https://example.com/do-not-purge/',
    ];

    $urls = array_diff($urls, $remove_urls);
    return array_values($urls);
}, 10, 2);

Notes

$urls is an array of full URLs scheduled for purge
$post_id is the ID of the post being saved or deleted
Always return the full modified $urls array
Matching should be exact (including protocol and slashes)
