New PHP Versions and Better Together Admin / Combination Discounts Admin

If you are using Better Together Admin (Zen Cart or osCommerce) and getting a log message that looks like this:

Only variables should be assigned by reference in YOUR_ADMIN/includes/xajax/xajax_core/ on line 268

or this:

PHP Strict Standards:  Non-static method xajaxPluginManager::getInstance() should not be called statically, assuming $this from incompatible context in YOUR_ADMIN/includes/xajax/xajax_core/ on line 269

Then please refer to the instructions for fixing this issue on the Better Together Admin help page.

The same instructions apply for Combination Discounts Admin.

osCommerce Updates!

osCommerce has been released, with changes to the MySQL layer. If you are getting messages like:

PHP Warning:  mysql_num_rows() expects parameter 1 to be resource, object given in ...


Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource

then simply change the call “mysql_num_rows” to “tep_db_num_rows” in the following places:

osCommerce Better Together includes/modules/order_total/ot_better_together.php line 418(if using Buy Both Now, line 389)
osCommerce Quantity Discounts includes/modules/order_total/ot_quantity_discount.php line 547
osCommerce Big Chooser includes/modules/order_total/ot_big_chooser.php lines 55 and 1220
osCommerce Big Spender includes/modules/order_total/ot_bigspender_discount.php lines 48 and 716
osCommerce Table Discounts includes/modules/order_total/ot_table_discounts.php lines 131 and 566

So the old code looked like this:

        $this->_check = mysql_num_rows($check_query);

the new code will look like this:

        $this->_check = tep_db_num_rows($check_query);

Multiple VAT Levels and my Zen Cart discounts

Every once in a while, a European customer complains that tax recalculation in my Zen Cart mods is not working correctly for their store with multiple levels of embedded taxes.  (This is also an issue in osCommerce.)

Here’s what to look for: non-unique strings in the descriptions of taxes (this is shown in Admin->Locations/Taxes->Tax Rates)


Because of the way Zen Cart (and osCommerce) represent taxes in the order object, the tax descriptions must be unique to allow for reverse lookups.  So try changing the strings “Varav moms” to “Varav moms (1),” “Varav moms (2),” etc. to make them unique.
