Pikachu2000 Posted December 1, 2010 Share Posted December 1, 2010 The query is failing. Echo the query string and mysql_error() right after checking the number of rows. That should shed some light on it. Link to comment https://forums.phpfreaks.com/topic/220303-php-search-functionality-not-working/#findComment-1141603 Share on other sites More sharing options...
