osCommerce site migration to PHP5

*Matt* · 11-10-2008, 05:14 PM

I have a number of clients sites running osCommerce or a derivative of osCommerce. As I deal with the PHP5 migration, I will post here problems/ solutions that I encounter so that others can successfully make the migration as well.

Problem 1: Global variables no longer supported
Note: there are solutions out there to deal with this, but most of these "solutions" aren't any better than simply re-enabling global variables within an .htaccess file. From a security perspective, any security risks associated with global variables have already most likely been addressed. So, here's the lines to add to your .htaccess file for osCommerce:

Code:

php_value register_globals 1
php_value register_long_arrays 1

Problem 2: Another issue comes up in your admin/includes/classes/upload.php file that will result in the administrative login screen not loading. If you view your PHP error logs, you will see an entry like Cannot re-assign $this in /big/dom/xdomain/.../admin/includes/classes/upload.php. This is easy enough to fix, just open admin/includes/classes/upload.php and on about line 30, comment out the following line:

Code:

$this = null;

and add

Code:

unset($this);

so that it reads:

Code:

//$this = null;
unset($this);

If you are running osCommerce, or a derivative thereof, and experience problems after implementing these fixes, feel free to post here.

I'm not running osCommerce or derivative of it, but I tried this solution anyhow. It did enable my variable to echo in some places but not in others.

I have over the years learned enough PHP to set up all my sites in PHP and be able to cut down a lot of work by using variables and a few if-then statements and arrays. I'm not a "real" programmer, so I can only understand the simplest of explanations. However, I'm hoping someone can help. All of a sudden, none of my sites work. The variables from the URL are not being echoed in includes. Help!!

Look in logs_cgi to see if there are recent errors.

If you see $this and it does not look like it is being used as an object ($this->whatever, near code with 'class', 'public'), then rename it everywhere.

I would prefer to keep this thread focused on osCommerce-related issues. izann, could you start a new thread and post some sample code that you are having problems with?
