If Condition

i am creating a kind of search using dropdown boxes to search the database. I have got two dropdown boxes one called location and one called cuisine i have sorted out some if statement.

so that it works if they select either one or the other and if they select any location or any cuisine but the problem comes when i need them to be able to select a cuisine in a particular location ie on bothe boxes.

i need it if both are selected at the same time then search the database via location and cuisine. can anybody help here is the code for the two files.
