Page re-load to show ads randomly

clairey · 21-02-06

Hi
I am looking for some advice / help
I have a listings website, and would like to have the first 5 or so listings randomly re-shuffled so a different one shows at the top every time the page is visited/re-loaded. Does anyone know of some code / a program that can do this? My html is fairly basic, javascript even more basic ... don't know where to start ... anyone have any advice / pointers?
Thank you
Claire

Do a search for iframes.

Or in PHP create a page with just the ad and a meta refresh at the top then in your PHP that is to show the ad use the php include..

PHP Code:


			
<?

include 'adverts.php';

?>

You could try something like:

PHP Code:


			
<?php 

$i=rand(1,5);

switch ($i) {

case 1:

   echo '<a href= "link1"><img src="image1.jpg"></a>';

   break;

case 2:

   echo '<a href= "link2"><img src="image2.jpg"></a>';

   break;

case 3:

   echo '<a href= "link3"><img src="image3.jpg"></a>';

   break;

case 4:

   echo '<a href= "link4"><img src="image4.jpg"></a>';

   break; 

case 5:

   echo '<a href= "link5"><img src="image5.jpg"></a>';

   break; 

}

?>

Hi, I've only just registered with this forum yesterday, however, as I've been teaching myself php for some time now, I've used a few developer forums and reading your post reminded me of something that I printed off a forum ages ago and would hopefully use myself once I was ready. If you are new to php, it is good starting point as it might outline what might required for you you to achieve this.
As I'm not totally sure what you list on your website, I'm assuming that you mean affiliate banners linking to various merchants. I've taken a different approach to displaying them as I've made a menu down the side of the page where the user selects the relevant banners to be displayed of interest to the user. Also, I use cookies and have a users database to enable me in the future to just display the banners which reflect the users searching history of subject matter.
Anyway, I hope this url link will be of some use.

You could have a look at phpadsnew and set up a number of zones on your page.

Phpadsnew will then take care of the rotation for you.

If you want a quick and easy method you are probably better of sticking with a javascript solution.

Have alook at this example, a bit of cut and paste and you should have it working in no time.

Nothing better than a JavaScript challenge for Breakfast to get the brain in gear for the day

Have a go with this - it will put all paragraphs (p tags) within the div having id='container' in random order. If the client doesn't have JavaScript enabled it doesn't matter; they'll just stay in the order you code them in.

HTML Code:

<html>
  <body>  
    <div id='container'>
      <p>This is paragraph 1</p>
      <p>This is paragraph 2</p>
      <p>This is paragraph 3</p>
      <p>This is paragraph 4</p>
      <p>This is paragraph 5</p>
    </div>  
    <script type='text/javascript'>    
    var container = document.getElementById("container");    
    container.style.visibility = 'hidden';    
    var elements = container.getElementsByTagName("p");    
    var temp = "";
    var swap = 0;
    for(var i = 0;i < elements.length;i++)
    {
      temp = elements[i].innerHTML;
      swap = Math.floor(Math.random()*elements.length);
      elements[i].innerHTML = elements[swap].innerHTML;
      elements[swap].innerHTML = temp;
    }    
    container.style.visibility = 'visible';    
    </script>    
  </body>
</html>
