In my site I want to place a javascript ad code( from Zedo) which is popping up one window for each page visit by the user which is quite nagging.

Ideally what I want is to pop up the ad after user leaves the site or closes the window.

At least I want is to show single pop up in the whole guest session.

I place the ad code before </body> in page.tpl.php but it gets executed for every page.

I'm thinking to make it better by using this logic:

if(time() % 3 == 0)
//javascript ad code here

At least this will reduce pop up by 3 times.

Are there any better ideas?


You can use one cookie, if is the first time to the user enter into your page then create a cookie, when the user change of page you will check if the cookie exists and if exists don't show up the ad.

  • Will adding this cookie checking code affect caching of theme and template files in anyway? – AgA Dec 17 '11 at 7:57
  • No, if handle the cookie using javascript instead of php, with JS doesn't matter what kind of cache are you using in your project. – Gnuget Dec 17 '11 at 8:19
  • The ad code is getting executed by including a js file from the ad server. How do I wrap it with javascript function to get & set cookie? Thanks for your answer. – AgA Dec 17 '11 at 8:29
  • I've created a question for code to include jquery code : drupal.stackexchange.com/questions/17729/… – AgA Dec 17 '11 at 10:45
  • ahh, i answer your question here: drupal.stackexchange.com/a/17762/4362 – Gnuget Dec 17 '11 at 23:27

You could set a cookie like this when the user first enters the site:

// php
if(!isset($_COOKIE['ad_zero'])) {
   // display your ad and set the cookie

You could also use jQuery Cookie Plugin like this:

if($.cookie('ad_zero') != 1) {
  // display your ad and set the cookie
  $.cookie('ad_zero',1, { expires: 1 });
  • Thanks, I need more help with your second example. Before I saw your answer I already asked this question at : drupal.stackexchange.com/questions/17729/… – AgA Dec 17 '11 at 10:44
  • Finally I used this method but I was looking for the following solution and it worked only that for including another cookie plugin in Drupal, I find this method easier. – AgA Dec 18 '11 at 4:19
