Form,Javascript,multiple choice, php

[Anon]

Hi,

I've got stuck on a little form problem.

<b>Background</b>:
I have the need to do something like this in my form:

http://www.bjorn3d.com/temp/test.php

(I found it easier to show than to try to explain :-))

The script works fine. However - there is a small problem when I try to access the values selected.

<b>The Problem</b>
I found out that in PHP you can access multiple selected entries in a list by naming the <select>-list like an array (for instance "fields[]". Then you can pick up all selected values via a code like:

foreach($fields as $value)
etc.

However ... I can't name the select-list "fields[]". I get a javascript-error. If I name it "fields" then it no longer is an array and thus I can't get anything else than the last selected value out of $fields......

Anyone who can solve my dilemma?

Thanks in advance

perhaps there's a workaround via variable variables:

name the fields field1, field2 etc and process them via

${"field".$i}

instead of

$field[$i]

Bjorn,

You need to reference your javascript like this:

document.formname.elements['field[]',1].value
document.formname.elements['field[]',2].value
document.formname.elements['field[]',3].value

etc...

where the number is the form element in the order it appears on your html page.

Hope this helps
