Passing multiple values from a select box

[macca_25]

Hi all,
I am currently having trouble passing multiple selected values from a select box. Currently, when the form is submitted, it is only passing the last value of the selected items.
Any ideas on how to send all selected values?
Here is the code so far:

<?
if ($_POST['add_prod']){
echo $_POST['list2'] . "<BR>";
exit;
} else {
?>
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
sortitems = 1;  // Automatically sort items within lists? (1 or 0)

function move(fbox,tbox) {
for(var i=0; i<fbox.options.length; i++) {
if(fbox.options[i].selected && fbox.options[i].value != "") {
var no = new Option();
no.value = fbox.options[i].value;
no.text = fbox.options[i].text;
tbox.options[tbox.options.length] = no;
fbox.options[i].value = "";
fbox.options[i].text = "";
   }
}
BumpUp(fbox);
if (sortitems) SortD(tbox);
}
function BumpUp(box)  {
for(var i=0; i<box.options.length; i++) {
if(box.options[i].value == "")  {
for(var j=i; j<box.options.length-1; j++)  {
box.options[j].value = box.options[j+1].value;
box.options[j].text = box.options[j+1].text;
}
var ln = i;
break;
   }
}
if(ln < box.options.length)  {
box.options.length -= 1;
BumpUp(box);
   }
}

function SortD(box)  {
var temp_opts = new Array();
var temp = new Object();
for(var i=0; i<box.options.length; i++)  {
temp_opts[i] = box.options[i];
}
for(var x=0; x<temp_opts.length-1; x++)  {
for(var y=(x+1); y<temp_opts.length; y++)  {
if(temp_opts[x].text > temp_opts[y].text)  {
temp = temp_opts[x].text;
temp_opts[x].text = temp_opts[y].text;
temp_opts[y].text = temp;
temp = temp_opts[x].value;
temp_opts[x].value = temp_opts[y].value;
temp_opts[y].value = temp;
      }
   }
}
for(var i=0; i<box.options.length; i++)  {
box.options[i].value = temp_opts[i].value;
box.options[i].text = temp_opts[i].text;
   }
}
// End -->

Change the names of the list boxes from list1 and list2 to list1[] and list2[]. and then u get all the multiple selections in the post as $_POST[list1][0] and so on.

Thanks for the reply.
I tried doing that earlier but when i try to pass the values from one list box to the other they don't get passed.

[PallaviDalvi]

if i'm not getting confused....when u move the value from one list box to another u wud be using the id and for a post u use the name. so i guess it shud not interfere with each other. havent tried this before...so maybe my assumption is wrong. correct me if it is.

[macca_25]

I think you are correct.
I'm still confused myself however 🙂
