array variables in the $_POST vars

[Anon]

OK... so, say you have a form like this:

<form action="page.php" method="post">
<input type="hidden" name="var[]" value="1">
<input type="hidden" name="var[]" value="2">
<input type="submit" value="press me!">
</form>

... and then you want to get to it from the page you send the form to, with the $_POST vars. How do you do that? this doesn't work:

<?php

while (list($key,$val)=each($_POST['var']))
{
// do something
}
?>

Neither does it work if I do $_POST['var'][] or something...

Well, you can get a list of what it shows using a foreach (I'd test it and put it but I don't have the ver with _POST in it).

foreach($_POST['var'] as $key => $value) {
echo $key . " => " . $value;
}
