PHP and Javascript

[Anon]

Hi

I have 2 select box'es (Multiple select) and some data in one, and when the user select a item and press a button, the item is moved to the other select/list box.

My problem is that when the user hit's the submit button, I what to know which items the user have in the second listbox. Normally one could name the listbox list[] which then contains the items, but if I use [] in the name, Javascript can't see the listbox.

How to solve this ?

Thanks in advance.

Figure out what number element the second listbox is, and refer to it with form.element[x].

I've got the same problem - but this time with an array of checkboxes. I want to be able to check them all if the 'select all' checkbox is checked.

I've identified the elements on the form and everything is fine with IE - but as soon as I test it with AOL browser it fails again.

Any ideas?

Darren's answer doesn't appear to work. The javascript refers to the checkbox as form.checkbox.

Unfortunately, javascript claims that "checkbox[]" in the php form has no properties.

The "check all" js function works great as long as I use "checkbox" and NOT "checkbox[]" as required in php.

Has anyone made this work? What am I missing here?

Thanks.

try using "ID" attribute of the checkbox field
like
<input id="av" type="checkbox" name="available_for[]" value=<?echo $var_id?>>

<script language="javascript">
alert (document.myform.av[1].value);
</script>

tried only with IE 5

THANK YOU SO MUCH!
It works in Konquerer and Mozilla 0.9.2.1 and that is good enough for me.
