Thread: Pass all values in a select multiple field

After you post the page, you should be able to do something like this:

PHP Code:

    $value=$_POST['listbox2'];
    if ($value){
     foreach ($value as $str){echo 'You selected ',$str,'<br />';}
    } 


edit: scratch that, just realized you're trying to pass all items in the listbox...let me ponder that

Okay, one way to handle this is to autoselect everything using JavaScript when you submit the form:

Code:

function selectall(form)
{
	var elem = form.elements['listbox2'];
	
	for (i = 0; i < elem.length; i++)
	{
		elem[i].selected = true;
	}
}

I think this is more of a JS issue.

Only items that are selected would be posted back to be retrieved on the server side. So, you have to get the items in the listbox into a retrievable form first.

I'd think some form of JS function that takes the items in your listbox and populates a hidden field before the form is submitted so the value from the hidden field can be retrieved on the server.

Unless anyone else has any other ideas..

<edit>J already posted a solution. I think his way you'd see the elements selected (highlighted) just before the form submits, but it should work</edit>
