zxb2I am by no means a PHP expert, but what I would like to do is manually refresh a certain posts cache when a comment is inserted.
I realize Wp-cache already does this. However, my comment system is separate from WordPress and is integrated into a forum.
Looking at the WP-cache source I saw this function:
function wp_cache_post_change($post_id) {
global $file_prefix;
global $cache_path;
global $blog_id;
static $last_processed = -1;
// Avoid cleaning twice the same pages
if ($post_id == $last_processed) return $post_id;
$last_processed = $post_id;
$meta = new CacheMeta;
$matches = array();
wp_cache_writers_entry();
if ( ($handle = opendir( $cache_path )) ) {
while ( false !== ($file = readdir($handle))) {
if ( preg_match("/^($file_prefix.*)\.meta/", $file, $matches) ) {
$meta_pathname = $cache_path . $file;
$content_pathname = $cache_path . $matches[1] . ".html";
$meta = unserialize(@file_get_contents($meta_pathname));
if ($post_id > 0 && $meta) {
if ($meta->blog_id == $blog_id && (!$meta->post || $meta->post == $post_id) ) {
unlink($meta_pathname);
unlink($content_pathname);
}
} elseif ($meta->blog_id == $blog_id) {
unlink($meta_pathname);
unlink($content_pathname);
}
}
}
closedir($handle);
}
wp_cache_writers_exit();
return $post_id;
}Basically can I just give that function a post ID and it'll update the cache for the specified post?
I'm going to setup a local server and try it, but I wondered if anyone here did the same and could guide me on this.
