osCommerce: Session save path Fix

If you are using MySQL based sessions in your osCommerce installation and your PHP runs with Safe Mode set to On, you receive the following message:

Warning: session_save_path() [function.session-save-path]: SAFE MODE Restriction in effect. The script whose uid is X is not allowed to access owned by uid Y in /path/to/your/oscommerce/catalog/includes/functions/sessions.php on line 149

We also recommend this MOD when your web server has Safe Mode Off too.

Open:
catalog/includes/functions/sessions.php

Find:

  function tep_session_save_path($path = '') {
    if (!empty($path)) {
      return session_save_path($path);
    } else {
      return session_save_path();
    }
  } 

Replace with:

  function tep_session_save_path($path = '') {
    if (STORE_SESSIONS != 'mysql') {
      if (!empty($path)) {
        return session_save_path($path);
      } else {
        return session_save_path();
      }
    }
  } 

Open:
catalog/admin/includes/functions/sessions.php

Find:

  function tep_session_save_path($path = '') {
    if ($path != '') {
      return session_save_path($path);
    } else {
      return session_save_path();
    }
  } 

Replace with

  function tep_session_save_path($path = '') {
    if (STORE_SESSIONS != 'mysql') {
      if (!empty($path)) {
        return session_save_path($path);
      } else {
        return session_save_path();
      }
    }
  } 

Save and close all files and it’s done!
