javascript with php explode? - Please help

[sgtpepper]

I am trying to get this piece of javacode to place the results from list2 into a variable called selecttown[]

Everytime I do, I break the java...I am still learning...so I am wondering if you can help me get this to work...


<?
session_start();
session_unset();
session_register("selecttown");
session_register("bedroomsel");
session_register("bathselect");
session_register("lowprice");
session_register("highprice");
header ("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
?>
<script>

var isNS4 = (navigator.appName=="Netscape")?1:0;

</script>
<SCRIPT LANGUAGE="JavaScript">

<!-- Begin
function move(fbox, tbox) {
var arrFbox = new Array();
var arrTbox = new Array();
var arrLookup = new Array();
var i;
for (i = 0; i < tbox.options.length; i++) {
arrLookup[tbox.options[i].text] = tbox.options[i].value;
arrTbox[i] = tbox.options[i].text;
}
var fLength = 0;
var tLength = arrTbox.length;
for(i = 0; i < fbox.options.length; i++) {
arrLookup[fbox.options[i].text] = fbox.options[i].value;
if (fbox.options[i].selected && fbox.options[i].value != "") {
arrTbox[tLength] = fbox.options[i].text;
tLength++;
}
else {
arrFbox[fLength] = fbox.options[i].text;
fLength++;
}
}
arrFbox.sort();
arrTbox.sort();
fbox.length = 0;
tbox.length = 0;
var c;
for(c = 0; c < arrFbox.length; c++) {
var no = new Option();
no.value = arrLookup[arrFbox[c]];
no.text = arrFbox[c];
fbox[c] = no;
}
for(c = 0; c < arrTbox.length; c++) {
var no = new Option();
no.value = arrLookup[arrTbox[c]];
no.text = arrTbox[c];
tbox[c] = no;
}
}
// End -->

Again, the goal is to make my results for list2 become selecttown[]

[Phil Karras]

The only place I see "selecttown" is in the PHP section:

<?
session_start();
session_unset();
session_register("selecttown");
session_register("bedroomsel");
session_register("bathselect");
session_register("lowprice");
session_register("highprice");
header ("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
?>


As far as I know then there is no JavaScript var called selecttown, QED you can't get there from here.

To place a form-field value into another var you use:

var selecttown = document.form.list2.value;

<!-- with the name of the fome = 'form' -->
<form name='form' action="maincode.php" method="POST">

If the form is not named you use:

var selecttown = document.forms[0].list2.value;

assuming this is the first form in the forms[] array.
