Checkbox check javascript/php

Hello!
I have a form where I want to check only one checkbox. In javascript this is easy but the problem is that I use MySQL and I have a database that spits out the checkboxes. Which means I don't know how many checkboxes there are.
I.e. I have table with 5 elements and this would generate 5 checkboxes. Now when I check one box it should be checked and the others, if there are any, should be unchecked. Next time though it might be more or less checkboxes. Please help!

why dont you just use radio boxes for your options. much simpler if you only want one option checked.

I know, but they aren't as goodlooking as checkboxes. Any other ideas?

i believe you can do this in javascript. if you already have a javascript available for premade chkboxes. why dont you just have php generate a javascript for this depending on the number of results you have.

But I still don't know how many or the names on the checkboxes. How do I referr to somethimng that don't have a name?

you generate the javascript on runtime when you fetch your info from the database.

place the names of your checkboxes in an array, then after you've created all the checkboxes, you can now generate the javascript for this depending on the number of options you have.
