Someone asked how he could delete all the transients from a WordPress multisite, as I wrote the code for him, thought to share it here for everyone 🙂

if ( is_multisite() ) { global $wpdb; $all_sites = $wpdb->get_results( "SELECT * FROM $wpdb->blogs" ); if ( $all_sites ) { foreach ($all_sites as $site) { $wpdb->set_blog_id( $site->blog_id ); $wpdb->query( "DELETE FROM `{$wpdb->prefix}options` WHERE `option_name` LIKE ('_transient_%')" ); } } } |
Greetings, Thank you for the code. It works perfect. I added a couple more conditions to get rid of the new “nextgen gallery” crap.
Cheerz
get_results( "SELECT * FROM $wpdb->blogs" );
if ( $all_sites ) {
foreach ($all_sites as $site) {
$wpdb->set_blog_id( $site->blog_id );
$wpdb->query( "
DELETE FROM
{$wpdb->prefix}optionsWHERE
option_nameLIKE ('_transient_%')or
option_nameLIKE ('_site\_transient\_%')or
option_nameLIKE ('displayed\_galleries\_%')" );
}
}
}
