Confused......always confused........

I hope one of you can see what the heck is wrong with my code.

I was attempting to have a multiple select box and I know that you can use [] on the select name to convert to an array.

But when I submit the info, for some reason I can't figure out, I can't get anything from the variable using a for loop.

Right now I am just trying to print out the array on the same page just so I can see if it is working.

Here is the code....

<?php
if ($submit) {
for ($i=0; $i < sizeof($users[]); $i++) {
print "$users";
}
}
<form name="get_users" method = get action = getusers.phtml>
<select name="users[]" multiple size=10>
then all my users are listed here.
</select>
</form>
?>

Any advice anyone?

for ($i=0; $i < sizeof($users[]); $i++)

This is not right. For sizeof(), you want the bare array name, not
an elment of it, i.e. 'sizeof($users)'.

Otherwise, it's just as easy to use an each() loop:

reset($users);
while (list($key,$value) = each($users))
...

For starters, put a dollar sign inside your brackets in front of the "i" like so:

print "$users[$i]";

That should make the print statement work correctly.

....just made that mistake.

I am not new to programming. Honest. No really. I swear. I also can't believe I spent two hours overlooking that damned $ in front of the i.

Damn.

Thanks guys.
