general.php - try to change tax settings

[MLu]

I have tried to include a switch/case in /includes/functions/general.php, with the intention to set $country_id and $zone_id based on the language selected by the visitor. The code example below is only test data, but I do not understand why it always selects the "default" value despite of the visitors choice.

 

Is general.php only executed at startup, so that any subsequent changes in $HTTP_GET_VARS['language']) does not reflect, or ???

 

Any help would be greatly appreciated.

// Returns the tax rate for a zone / class
// TABLES: tax_rates, zones_to_geo_zones
 function tep_get_tax_rate($class_id, $country_id = -1, $zone_id = -1) {
   global $customer_zone_id, $customer_country_id;

   if ( ($country_id == -1) && ($zone_id == -1) ) {
     if (!tep_session_is_registered('customer_id')) {
// Old code shown below
//      $country_id = STORE_COUNTRY;
//      $zone_id = STORE_ZONE;
// End of old code
// My modified code shown below  
 switch ($HTTP_GET_VARS['language']) { 
    	 case 'da': 
     $country_id = '57';
      	 $zone_id = '0';
       break; 
       case 'sv': 
     $country_id = '203';
      	 $zone_id = '0';
       break; 
 default:
     $country_id = '81';
      	 $zone_id = '0';
       break; 
// End of my modified code
 } 
     } else {
       $country_id = $customer_country_id;
       $zone_id = $customer_zone_id;
     }
   }
