HowTo: Solution to Errors when Configuring OsCommerce with PayPal or Upgrading OsCommerce to PHP5

configureA couple weeks ago I was in charge of configuring an OsCommerce account with PayPal Module. Unfortunately, when searching on the internet I came to find out that there wasn’t a lot of documentation on the web about this subject. So I had to spend a few more minutes trying to figure out some things that I wasn’t familiar with. Fortunately, I didn’t run into many problems, since I had configured OsCommerce a little while ago already, and I only had to take care of configuring PayPal.

However, there were a couple problems that  I noticed there wasn’t a lot of help documentation available online, so here I leave you a pretty short and specific post which I think is going to be very helpful for those who are looking to fix some problems while configuring their OsCommerce with Paypal or upgrading.


Shipping Modules not showing up in OsCommerce Admin Module


On the live server  login to the Admin page, and go to Tools > Server Info. Search for “DOCUMENT_ROOT” then copy and paste the value for that field into admin/configure.php and add the catalog directory onto the end of it, like this:

define(‘DIR_FS_CATALOG’, ‘/home2/www/public_html/catalog/’);

This fixed both the images folder issue and the modules issue. I have tested installing/removing modules and it’s all working ok.


Error When Clicking on Customers in the OsCommerce Admin page.

This problem usually happens when you upgrade your OsCommerce site to PHP5 version.  So , if you are using PHP version 5, then this might be the answer.

Find these lines:

$customer_info = array_merge($country, $info, $reviews);

$cInfo_array = array_merge($customers, $customer_info);

and change them to:

$customer_info = array_merge((array)$country, (array)$info, (array)$reviews);

$cInfo_array = array_merge((array)$customers, (array)$customer_info);

I hope you find this short tutorial useful. When I run into this problems I wished I would have found a post like this, so here it is in a nutshell just for you. Until next time!

  1. You have made a nice effort, strive to continue!

  2. I’ve finally gave up on OSCommerce. I tried it but was starting to be put off by its security issues, complex code & slow release cycles. As an alternative option, I tried Opencart & Magento but ended up using DLGuard ( for its multiple payment processor support, security and automation. I put up a full review at sell eBooks and software online.

  3. Thanks for making my morning a little bit better with this great article!!
