Add this to your plugin !
-
Hello !
I suggest you to add this option in your awesome plugin :
“Delete expired transients” because some expired transient can always exists even if their lifetime is outdated.This is the query to run :
$wpdb->query( "DELETE FROM $wpdb->options WHERE option_name IN (SELECT CONCAT('_transient_',SUBSTRING(option_name,20,44)) FROM $wpdb->options WHERE option_name LIKE '_transient_timeout_%' AND option_value < UNIX_TIMESTAMP() AND LENGTH(option_value)=10 UNION SELECT CONCAT('_transient_timeout_',SUBSTRING(option_name,20,44)) FROM $wpdb->options WHERE option_name LIKE '_transient_timeout_%' and option_value < UNIX_TIMESTAMP() AND LENGTH(option_value)=10)Thank you !
