It's all in the query and is not as hard as it seems. :) Basically, you need to write a query that selects all of the options that the user selected.
For example, if the user selects
rooms=2
city=New York
Your query would look something like:
Code:
$query=mysql_query("SELECT * from TABLE where (field_rooms='".$_POST['rooms']."') AND (field_city='".$_POST['city']."')"); That should give you enough to go on if you have basic mysql and php knowledge. If you don't know much about mysql and php, you should use a pre-packaged system.
