Multiple Selection Lists & PHP

[ShibSta]

Ok, I have 2 multiple selection lists. I am using javascript so that users can select items from list 1 and move them to list 2. When the user submits the form I need my php to get the values he has/she has in list 2...

 

I have done printf($_POST['send_to']); and it only shows one value, even when multiple are selected. I read that I need to change it's name to list_2[] but if I add the brackets to the name my javascript quits working...

 

Any suggestions?

 

Here is my JS/HTML, my PHP is simply printf($_POST['send_to']); which prints the data in the array.

 

<script type="text/javascript">
<!--
function compareOptionValues(a, b)
	{
	var sA = parseInt(a.value, 36);
	var sB = parseInt(b.value, 36);
	return sA - sB;
	}
function compareOptionText(a, b)
	{
	var sA = parseInt(a.text, 36);
	var sB = parseInt(b.text, 36);
	return sA - sB;
	}
function moveDualList(srcList, destList, moveAll)
	{
	if ((srcList.selectedIndex == -1) && (moveAll == false))
		{
		return;
		}
	newDestList = new Array(destList.options.length);
	var len = 0;
	for (len = 0; len < destList.options.length; len++)
		{
		if (destList.options[len] != null)
			{
			newDestList[len] = new Option(destList.options[len].text, destList.options[len].value, destList.options[len].defaultSelected, destList.options[len].selected);
			}
		}
	for (var i = 0; i < srcList.options.length; i++)
		{
		if (srcList.options[i] != null && (srcList.options[i].selected == true || moveAll))
			{
			newDestList[len] = new Option(srcList.options[i].text, srcList.options[i].value, srcList.options[i].defaultSelected, srcList.options[i].selected);
			len++;
			}
		}
	newDestList.sort(compareOptionValues);
	for (var j = 0; j < newDestList.length; j++)
		{
		if (newDestList[j] != null)
			{
			destList.options[j] = newDestList[j];
			}
		}
	for (var i = srcList.options.length - 1; i >= 0; i--)
		{
		if (srcList.options[i] != null && (srcList.options[i].selected == true || moveAll))
			{
			srcList.options[i] = null;
			}
		}
	}
	//-->
</script>

I did post this in the PHP section, I wasn't really thinking that it had more to do with JS... (Braindead. Sorry.)

do

 

print_r($_POST['send_to']);

 

and see what is returned or even echo it then go from there

Please read the post before responding.

You haven't properly quoted your JS event handlers -- you have doubles within doubles.

I have tried several variations of quotes, I cannot get it to work. I am new to javascript and normally stick to PHP. Could you please show me how it needs edited as I tend to be more of a visual learner... It seems like the quotes would be a logical answer to the issue but I cannot get it working properly...
