Problem with setting a cookie variable with a hook!

[Citizen]

I setup a sidebar for navigation on my forums. I want the sidebar to be removable if my users click a link at the bottom of the side bar. The sidebar works great, but if you click the "remove" link, nothing happens.

Hook Name: "Sidebar Cookie"

Hook Location: global_start

Hook Code:

$show['sidebar'] = true;

if ($_REQUEST['do'] == 'hidesidebar')
{
   vbsetcookie('hidesidebar', 1, true);
}

$vbulletin->input->clean_gpc('c', 'hidesidebar', 'TYPE_INT');

if ($vbulletin->GPC['hidesidebar'] == 1)
{
    $show['sidebar'] = false;
}

The template conditional:

<if condition="$show['sidebar']"> </if>

The "remove" link points to:

{$vbulletin->options['bburl']}/index.php?$session[sessionurl]do=hidesidebar

Any idea where the problem is?

The following should work:

PHP Code:

$show['sidebar'] = true;

if ($_REQUEST['do'] == 'hidesidebar')
{
   vbsetcookie('hidesidebar', 1, true);
}

$cookiename = COOKIE_PREFIX . 'hidesidebar';

$vbulletin->input->clean_gpc('c', $cookiename, 'TYPE_INT');

if ($vbulletin->GPC["$cookiename"] == 1)
{
    $show['sidebar'] = false;
}

Ok, I'm having problems, can anyone figure out how to get this to work with my "hide the sidebar" code....

I have this in my main template

PHP Code:

<table align="center" class="page" cellspacing="0" cellpadding="0"width="100%">
<tr valign="top">

<if condition="$show['left_column']">

<td width="175" id="collapseobj_gtpcloseleftcol" style="$vbcollapse[collapseobj_gtpcloseleftcol]"> 


And this is my navbar link before adding the plugin(works but doesn't keep settings between pages hence the need for a cookie...)

PHP Code:

<a href="#top"
onclick="toggle_collapse('gtpcloseleftcol')">SideBar</a> 


This is the code I have in my plugin just as suggested in the previous post

PHP Code:

$show['left_column'] = true;

if ($_REQUEST['do'] == 'hidesidebar')
{
   vbsetcookie('hidesidebar', 1, true);
}

if ($_REQUEST['do'] == 'showsidebar')
{
   vbsetcookie('hidesidebar', 0, true);
}

$cookiename = COOKIE_PREFIX . 'hidesidebar';

$vbulletin->input->clean_gpc('c', $cookiename, 'TYPE_INT');

$sidebar = $vbulletin->GPC["$cookiename"];

if ($sidebar == 1)
{
 $show['left_column'] = false;
} 


This is the nav bar link after the plugin code has been added

PHP Code:

<if condition="$sidebar == 0"><a href="./index.php?do=hidesidebar">Hide</if><if condition="$sidebar == 1"><a href="./index.php?do=showsidebar">Show</if></a> 


Now... the page takes 2 clicks of either link before it will swap to the other link and the sidebar does not go away... I'm stumped... can anyone help me figure this out? Also, is there another way to do the link so it doesn't force them back to the index page but will leave them on the page they are on like the old (cookieless) code does?
