Clickbank: redirect for multiple products

Hi,

I have a few products in my clickbank account and I would like my affilate to choose whcih one they want to promote.

For example, if they wish to promote ‘everydayexcel_money__manager’, they would have to put the link as ‘http://AFFILIATE.imktgworks.hop.clickbank.net/?ppid=everydayexcel_MM’.

I modified the wp__redirect function publiched in one of the forum topics http://www.s2member.com/forums/topic/clickbank-button-hack-another-instalation-2/ to redirect the customer to the relevant url. If I got the logic right, it should go to http://www.excel-course.com/e-courses/hidden-secrets-in-data-analysis-with-excel-20072010/ first before it is redirected to http://www.advanced-excel.com/everydayexcel_money_manager.html.

Instead of redirecting the visitor to http://www.advanced-excel.com/everydayexcel_money_manager.html, the redirect returned the following error:

Warning: Cannot modify header information – headers already sent by (output started at /hermes/waloraweb039/b2033/pow.jksynergyworks/htdocs/excel-course/htdocs/wp-content/mu-plugins/s2-hacks.php:2) in /hermes/waloraweb039/b2033/pow.jksynergyworks/htdocs/excel-course/htdocs/wp-includes/pluggable.php on line 881

Could anyone help me? The modified codes for redirect is as follows:

<?php
add_action('init', 'handle_custom_clickbank_redirections');
function handle_custom_clickbank_redirections()
{
	if(isset($_GET['ppid']))
	{
		switch ($_GET['ppid']) {
			case 'hsdae':
				$clickbank_checkout = 'http://www.excel-course.com/e-courses/hidden-secrets-in-data-analysis-with-excel-20072010/';
				break;
			case 'everydayexcel_MM':
				$clickbank_checkout = 'http://www.advanced-excel.com/everydayexcel_money_manager.html';
				break;
			default:
				$clickbank_checkout = 'http://www.excel-course.com/';
		}
		
		wp_redirect($clickbank_checkout);
		exit;
	}
}

Appreciate if anyone could help me with this.

Thanks in advance for your help.

This sounds to me like a PHP problem. What you are attempting to do is, when the page is opened, send a header telling the browser ‘This is the wrong document, you need to go *here*‘

The problem is, by the time you call the function, another part of the same page has already said ‘Ok, you have the right page, this is what format it’s in’... Headers enable a server to tell the browser things like: ‘404: I haven’t got that url’, or ‘500: There was a problem, but it was with the page, not the way you tried to access it’ without having to put that into the content of the document. Once the headers have been sent the browser treats everything else as part of the web page.

Basically, you either need to have that method run earlier, or use another method to direct that is part of the page content (like a javascript to redirect the browser)

Daniel, thanks for your help.
