Ad rotation, what do you think?

Dawg

I need to have a different ad show up on each page refresh or view.

I was thinking of having a function with an array containing the url and link for the ad. The function could randomly select an array element for display and generate the html code.
If I had a static list of ads and links, how would I use php to start at the top and move down the list on a page refersh?

Thanks
Dave

for random, you could do something like,

$ads = array(
	1  => 	array(
				'title' => 'add one',
				'url' 	=> 'http://fadsfasdf.ca/',
			),
	2  => 	array(
				'title' => 'add two',
				'url' 	=> 'http://vxczvzxc.ca/',
			),
	3  => 	array(
				'title' => 'add three',
				'url' 	=> 'http://rweqrwqe.ca/',
			),
);

$victim = rand(1,(count($ads)));

$ad = $ads[$victim];

for toggling through, you could do something like

session_start();

$ads = array( 
    1  =>     array( 
                'title' => 'add one', 
                'url'     => 'http://fadsfasdf.ca/', 
            ), 
    2  =>     array( 
                'title' => 'add two', 
                'url'     => 'http://vxczvzxc.ca/', 
            ), 
    3  =>     array( 
                'title' => 'add three', 
                'url'     => 'http://rweqrwqe.ca/', 
            ), 
); 

$count = count($ads);

$_SESSION['ad'] = (!isset($_SESSION['ad']) || $_SESSION['ad'] == $count) ? 1 : $_SESSION['ad']+1;

$ad = $ads[$_SESSION['ad']];

bored enough suggest another option:

echo $ads[array_rand($ads)];

I hate not knowing all functions writes down array_rand()

my brain is not big enough for all php functions, its hardly big enough for all the colours of the rainbow. 🙂

Thanks ColdwerTurkey. I got it working.

I have not worked with sessions at all. I was trying to get the thing working in an include file or a class. But I keept failing.

With sessions, do they have to start from the page and then pass the session id over to the class to do what needs to be done??

I wanted to make this an easily reusable tool for a few pages on the site.

Thanks again
