validating checkboxes

[cgillin]

In a form I have an an array of checkboxes with each one reading something like..

<input type="checkbox" name="states[]" value="PA">

My problem is I want to do form validation but not sure how to check if each checkbox has been checked or not. Does anyone know of either a way to use javascript to validate an array of checkboxes declared as above or of another way to pass the arry into PHP other than declaring ...

name="states[]"

Thanks for your help
Chris

What kind of validation do you want to do?

Sorry, should have said that before.

What I want to do through javascript is be able to determine which boxes have been checked and also have an option to select all checkboxes in the array.

Thanks

Checking all checkboxes -- this is a JavaScript question and as such is not in the scope of this forum. My one helpful hint here to point out that you can use the "id" attribute of a form field to reference that field, just as you can the "name" attribute. Thus, you can have a field defined as:

<input type="text" name="foo[1]" id="foo_1">

and make that field available to JavaScript and to PHP as an array element.

In terms of PHP, when the script is submitted, only those checkboxes checked will have values submitted.
