This doesn't work. Very very wrong approach. I see what you've tried to
accomplish here but I must say this isn't the way php works, you can't
assign a php variable from javascript like this.
Here's a list of things to do for you:
a) Add an action to your form, action="<?php echo $_SERVER['PHP_SELF'] ?> is
a good choice in this case.
b) Add a method to your form, and I recommend method="get" in this case.
c) Add a submit button to you form, a simple <input type="submit"/> will do
just fine for now.
d) Add this to your code
<?php
print_r($_GET); // This is just for debugging purpouses
$location=$_GET['author_pk']; // this be the real magic
echo "Location is: $location";
?>
e) click the fine submit button you've added and observe what happens.
f) if you really want a drop down list rather than a flat list, then remove
the size=20 from it.
g) report back what you've achieved and learned from this experience.
