migrate oscommerce links to zen

I've moved a site running oscommerce to a new site with zen-cart and a slightly different domain name... both sites are running and now I want to allow spidering of the new site and redirect from the old site to the new site. The old site does not seem to have functioning htaccess files. So I figure I should add a redirect line to application_top.php in the old site. Anyone done this before?

I want to put in a line that will redirect the old site products and categories to the new site. Shouldn't be too hard but I can't think after spending a week on the migration.
The items IDs are the same, categories are the same, except I did put all the previous categories down one level.

Thanks

To redirect a single page, the following would work from a PHP file:```php
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://www.mynewsiteurl.com/folder/index.php");

You could likely do some detecting of URL parameters and loop thru them to determine the right new URL to go to for all your products pages.

Something like this? But it isn't working:

if (isset($_GET['product_id']) and $_GET['product_id'] != "") {
$prodid=$_GET['product_id'];
$hdstring="http://www.mydvdshop.com/index.php?main_page=product_info&products_id=" . $prodid;
header("HTTP/1.1 301 Moved Permanently");
header("Location: " . $hdstring);
die();

}

elseif (isset($_GET['cPath']) and $_GET['cPath'] != "") {
$prodid=$GET['cPath'];
$hdstring="http://www.mydvdshop.com/index.php?main_page=index&cPath=45" . $prodid;
header("HTTP/1.1 301 Moved Permanently");
header("Location: " . $hdstring);
die();

}
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://www.mynewdvdshop.com/index.php");

The if tests ae failing and I always get the last link to index.php.

I do believe that is $_GET['products_id'] with an S in there ...

Yes! It works. I was wondering why my test file worked but the live file not.

Thanks
