using checkbox array with PHP and Javascript

[nozom]

I have a system that spits out the names of people. you can then check the box next to that name and they are added to a batch email list.

my checkbox is called LIST_ARRAY[] and the value is the persons id
<input type='checkbox' name='LIST_ARRAY[]' value='" . $row[ID] . "'>

this all works great except i want to add a javascript option which makes all the boxes checked. This is causing problems because i need to call the checkbox 'LIST_ARRAY[]' for it to work in php but javascript spits the dummy at the name because of the [] in it.

javascript:
<input type=button name="CheckAll" value="Select All" onClick="checkAll(document.searchres.LIST_ARRAY[])">

calls:
function checkAll(field)
{
for (i = 0; i < field.length; i++)
field.checked = true ;
}

if i call my checkboxes 'LIST_ARRAY' the js works fine but the PHP doesn't and so on.

anyone any ideas??

cheers,

Hi,

I'm not sure how cross compatible this is (it works on safari on mac) but -

<script language="Javascript">

function selectAll() {

for(i = 0; i < document.forms[0].elements['inputs[]'].length; i++) {
document.forms[0].elements['inputs[]'].checked = true;
}
}

</script>

<input name="inputs[]" type="checkbox" value=""><br>
<input name="inputs[]" type="checkbox" value=""><br>
<input name="inputs[]" type="checkbox" value=""><br>
<input name="inputs[]" type="checkbox" value=""><br>
<input name="inputs[]" type="checkbox" value=""><br>
<a href="javascript:;" onClick="selectAll()">select all</a>


I've just typed this in without testing it so there may be some typos, YMMV.

Cheers

Andrew
