How to search for several parameters from objects in a database?


Posted on 16th Feb 2014 07:03 pm by admin

I have a database with lots of information about objects.
Now I would like to search for 4 or 5 parameters at the same time (from a form) like this:

I choose from a select-box one parameter and then from another select-box (in the same form) another parameter.
Now I want all the objects that fit in with all the chosen parameters to be shown.

I have tried this:
Code: $query = "SELECT * FROM vaxtlista WHERE farg='$farg' AND typ='$typ' ORDER BY vetenskapligt";
and this:
Code: $query = "SELECT * FROM vaxtlista WHERE (farg='$farg' AND typ='$typ') ORDER BY vetenskapligt";
I don´t use LIKE and jokers because I know exactly what´s in the fields.

Nothing works.

Someone who has a clue about this? Please help
