Validate form select array -very frustrated

[grumpy]

Hello-
Is there a way to validate an array created by a form select field drop-down box? It seems impossible using javascript. I've tried for 2 days to get it to work with various javascript codes which apparently can't handle the [] required by php. Have received javascript code from other people who said it should work, but they all fail with the same error "null or not an object". This is holding up a project. Is there a bewtter way to do this?

Javascript is a little clumsy and I wouldn't use it for much of ANYTHING if you have access to something like PHP. Do the validation in PHP.

IE: (if you have the [] on the end of a multi-select list it will automatically make it an array)

foreach(selectListName as $selectListItem)
{
do validation on $selectListItem
}

That's it, you're done. You'll need to fill in the blanks and such but that's the basic workings of it all.

I think javascript is a good thing.

You can also just add an id attribute.
