Checkbox arrays, php, and javascript

[Anon]

In order for php to generate an array from multiple checkboxes having the same name, does the name of the checkboxes have to have a "[]" after it? For example:

<input type='checkbox' name='RelatedCheck[]' value='".$CriteriaID."'")

(This line is part of an echo statement and the CriteriaID is an ID field from a database.)

The problem is that if I remove the "[]" it seems to break the array in PHP. For example:

<input type='checkbox' name='RelatedCheck' value='".$CriteriaID."'")

However, if I leave the "[]", it breaks the form validation I am trying to do with javascript on the submit. Javscript doesn't seem to like the "[]" after the name. If anyone has run into the issue or has any possible solutions for me let me know. Thanks in advance.

If javaScript no like the $variable name, why not boot javaScript out of the picture and use PHP to validate instead?

Atleast that's how I've always done it.
And using PHP allows you to put friendly little messages into the page rather than using some ugly lil alert pop-up.

I am going to do that if there isn't an easy solution to the problem. Since I already have the javascript code for my form validation, I thought I would wait to see if anyone had a quick solution. You are probably right though. I may just have to use PHP to do the validation.

This is your solution (Can be found in the PHP manual if you look it up)...

Instead of writing:
document.formName.checkboxName
or
document.formName.checkboxName[]
wich will break the JavaScript because of the[]

write like this:
document.formName.elements['checkboxName[]']

I have tried this already and it still did not work.
