I've been looking for an answer to my problems for few hours, but it seems I don't look at the right place, or I'm the first to have a so twisted programing style.

I have a in my php code, with some input inside, that put every informations in a database. After that, I have another form, with others input that allows me to make some research in my DB.

Here the troubles comes.

If I want to find something in aprticular, I have to fill all the inputs, like "name", "nickname", "computer name", and it finds it well, with a "select * from db where name=name and nickname=nickname etc...".

But if i want to find every computers that one person have, I would just put his name, and I want that it shows me every row that contain that name.

In other words, I want that my MySQL query just ignore the variables that are not completed in the form, I set them to NULL by default, but I have the feeling that mysql think it is a value, and compare it to the data in the db.

If I only fill 1 input, it shows nothing, I have to complete all the fields..

Code incoming, don't be rude, I'm pretty beegining... and also sorry for my english. :(

in advance, thank you for your help.
