further to roderick's reply:
an array passed back to the server in a hidden form field will arrive in
your PHP script as a comma-delimited list, either in a POST variable, or
a GET variable.
this example uses the POST method --
<form name="testForm" action="test.php" method="post">
<input type="text" name="testText">
<input type="hidden" name="testHidden">
<input type="submit">
</form>
<script language="javascript">
testArray = new Array (1,2,3);
document.testForm.testHidden.value = testArray;
</script>
<?php
if (isset($_POST['testHidden'])) {
$tok = strtok($_POST['testHidden'], ",");
while ($tok) {
echo "element = $tok<br>";
$tok = strtok (",");
}
}
?>
