Php/Javascript problems with multiple select

[Ramses van Pinxteren]

hello,

I have a PHP/Javascript problem. If I want to make a multiple select
like this one:

$html .= "<td><selec t name='userid' onChange='chang euserinfo()' multiple
size='10'>";
$html .= "<option value=''>Select eer user</option>";
$html .= "<option value='1'>user 1</option>";
$html .= "<option value='2'>user 2</option>";
$html .= "<option value='3'>user 3</option>";
$html .= "<option value='4'>user 4</option>";
$html .= "<option value='5'>user 5</option>";
$html .= "<option value='6'>user 6</option>";
$html .= "</select>";
$html .= "</td>";

I can read this one out with javascript but accourding tot the PHP
manual I have to declare the select as follows to read it out in php:
$html .= "<td><selec t name='userid[]' multiple size='10'>";
and this is something that javascript does not want to swallow :'(

How can i make it so that both javascript and php can access the fields
and do their usefull stuff with it.

HELP MEEEEEEE :)

Greetz,
Ramses

<select id="userid[]" name="userid[]" onchange="chang euserinfo();">

and in the javascript use

FormObject=docu ment.forms['name of form'];
SelectObject=Fo rmObject.elemen ts['userid[]'];

you can then loop through the array SelectObject.op tions[], checking the
'selected' property to see which items have been selected

SelectionCount= 0;
for(n=0;n<Selec tObject.options .length;n++)
{
if(SelectObject .options[n].selected)
{
// option selected
SelectionCount+ +;
}
else
{
// option not selected
}
}

The SelectObject.se lectedindex property only shows the first selected
element.

You are incorrect. Javascript has no problem with elements named like
'userid[]', us the element name in the elements hash.
