    Hi There,

    Because i have some pages Updated with news every week on same time, I would like to Auto Purge them by cron Job. Is this Possible? I found this 

    add_action( 'save_post', 'my_custom_clear_cache', 10, 1 );

function my_custom_clear_cache( ) {
    $post_id = 123;
    $GLOBALS['quick_cache']->auto_purge_post_cache($post_id);
}

    I was put this into a Plugin, but it outputs my just some error messages.

    Any Idea?

    Thanks in Advance
    regards adrian

    It outputs me this message:

    add_action( 'save_post', 'my_custom_clear_cache', 10, 1 ); function my_custom_clear_cache( ) { $post_id = 123; $GLOBALS['quick_cache']->auto_purge_post_cache($post_id); }

    It looks like you forgot to add the opening <?php and closing ?> PHP tags to your plugin… 

    <?php
add_action( 'save_post', 'my_custom_clear_cache', 10, 1 );

function my_custom_clear_cache( ) {
    $post_id = 123;
    $GLOBALS['quick_cache']->auto_purge_post_cache($post_id);
}
?>

    Also note that this should be a Must-Use Plugin, not a normal WordPress plugin (more code is necessary for that). Otherwise, you can paste the code (without the <?php and ?> tags) into your theme’s functions.php file.
