php / javascript multiple select field

[chrislive]

hi everyone,

I have a javascript that will send the values of one multiple select field to another, which works fine, however for PHP to get the values of the field I need to name it as an array eg name="testing[]"

While both components work individually they do not together, if I specify in the js to update the values of testing[] it will fail.

is their a way to get around this? can php get this array any other way??

Thanks
Chris

Yes: use id on the select, and target it in javascript using the id.
You simply have to have the [] on the name as that's the only way to pass it as an array, unless you want to inroduce some very weird solutions, as far as I know

ok so how would i target the id for this:

onclick="moveDualList( document.myForm.listRight, document.form.listagain_id, true )"

if my field was like this:

<?php echo "<select MULTIPLE size=5 width=40 name=\"listagain[]\" id=\"listagain_id\">\n"; ?>

if you have this:
<form id=myform>
<select multiple id=myselect name="arrToPass[]">
...

then it'd be simply
document.myform.myselect to target the select element.
In your case I don't know what's inside the function, so can't tell anything for sure.

this was how i got it:

onclick="moveDualList( document.myForm.listRight, document.test.elements['listagain[]'], true )"

from the php manual 😉
