Опитвам се да филтрирам резултатите от търсенето на моята MySQL база данни, искам да филтрирам резултатите, като избирам стойности от две падащи полета, като първото поле е Клуб, а второто е Дивизия, за да мога да филтрирам резултатите по Дивизия и Клуб .
Проблемът ми е, че когато направя селекция в клубното поле, нищо не се случва, мога да избера от полето Дивизия и резултатите ще покажат избраната дивизия, но нищо не се случва, когато избирам по клуб.

АКТУАЛИЗАЦИЯ: Промених следния код от това:
if ($_REQUEST["club"]='') {
$search_string = " AND (club LIKE '%".mysql_real_escape_string($_REQUEST["club"])."%' OR (division LIKE '%".mysql_real_escape_string($_REQUEST["division"])."%')";
}
до това:
if ($_REQUEST["club"]<>'') {
$search_club = " AND (club LIKE '%".mysql_real_escape_string($_REQUEST["club"])."%' OR (club LIKE '%".mysql_real_escape_string($_REQUEST["club"])."%')";
}
и сега ще ми позволи да филтрирам по клуб и дивизия, но все още не мога само по клуб!
