Need help with setting session var

[zzz]

I have a link that when clicked POST hidden value, which needs to be set in SESSION. When clicked again needs to set another SESSION variable.

I am probably overcomplicating. I use a bit of JS to POST hidden field in order to hide it and not to append it to the URL. If there's a better way of doing it, I'd be ahppy to learn.

Here's what I have:

//js to submit form as POST
<script>
function hidePub() {
    document.pubFold.submit();
}
</script>

<?
// messed up logic
if ($pubDtls != "n") {
		$hideLnk = "hide";
		echo "<form name=pubFold method=post>
			  	<input type=hidden name=pubDtls value=n>
		      </form>";
} else {
		$hideLnk = "show";
		echo "<form name=pubFold method=post>
			  	<input type=hidden name=pubDtls value=y>
		      </form>";
}

$pubDtls = $_POST["pubDtls"];
$_SESSION["pub_details"] = $pubDtls;


//link
<a href='javascript:hidePub()' >".$hideLnk."</a>
?>

i'd say you are overcomplicating this only in insisted that it be a POST var. why not not simply make it a GET var? then you would not need all the JS stuff.

to keep it a hidden, posted value thats the best way, or use a submit button, but then it wont be a hyperlink

I can POST with JS, but what I'm having difficulties is with registering that var with the session. Assuming I get $_POST done does everything else look right?
