Help with custom conditionals

[harmor19]

In my templates I have

PHP Code:

 <if condition="$show_request_link">
    <br />
    Your request has been submitted
    <else />
    <if condition="$user[planid] < $hp[planid] AND $user[planid] > 0 AND $vbulletin->userinfo[posts] >= $hp[posts]">
    <br />
    <b><a href="hosting.php?do=upgrade&planid=$hp[planid]">Upgrade to this plan</a></b>
    </if>
    <if condition="$user[hosting_plan] == $hp[title]">
    <br />
    <else />
    <if condition="$vbulletin->userinfo[posts] >= $hp[posts] AND $user[planid] == 0">
    <br />
    <b><a href="hosting.php?do=request&planid=$hp[planid]">Request This Plan</a></b>
    </if>
    </if>
    </if> 


In my php file I have

PHP Code:

$checksubdomain = $db->query_read("SELECT * FROM " . TABLE_PREFIX . "temp_host_request WHERE userid='".$vbulletin->userinfo['userid']."'");
    $cs = $db->fetch_row($checksubdomain);
    
    $getplans = $db->query_read("SELECT * FROM " . TABLE_PREFIX . "hosting_plans WHERE planid ORDER BY posts");
    while($hp = $db->fetch_array($getplans))
    {
        $posts = $hp['posts'] - $vbulletin->userinfo['posts']; 
        
        if(!$cs['userid'])
        {
            $show_request_link = true;
        }

     
        eval('$hosting_plans .= "' . fetch_template('hosting_plans') . '";');
    } 


In this part I want it to check if their userid is in the "temp_host_request" table.

PHP Code:

  if(!$cs['userid'])
        {
            $show_request_link = true;
        } 


If the userid is not in that table then show the "Your request has been submitted" message.
