You need to rewrite or copy to the local code pool the following class Mage_Shipping_Model_Shipping
To rewrite:
class Company_Module_Model_Shipping_Shipping extends Mage_Shipping_Model_Shipping
{
public function collectCarrierRates($carrierCode, $request)
{
if (!$this->_isAvailable($carrierCode, $request)) {
return $this;
}
return parent::collectCarrierRates($carrierCode, $request);
}
/**
* @param string $carrierCode
* @param Varien_Object $request
* @return bool
*/
protected function _isAvailable($carrierCode, $request)
{
$regionCode = $request->getDestRegionCode();
switch ($carrierCode) {
case 'flatrate':
if ($regionCode == 'xyz') {
return false;
}
break;
case 'freeshipping':
if ($regionCode == 'abc') {
return false;
}
break;
}
return true;
}
}
If you want to copy the following class to the local code pool, find the method collectCarrierRates and add the following lines before the core code.
if (!$this->_isAvailable($carrierCode, $request)) {
return $this;
}
Add new method _isAvailable, you can use the same method as indicated above for the rewriting case.
You can move the hardcoded region dependency to config and make it user friendly.
As far as I can see there are no events in shipping (in payment there is payment_method_is_active). There are some on checkout level but I don't know appropriate for shipping. So I can suggest you to copy app/code/core/Mage/Shipping/Model/Carrier/Freeshipping.php and app/code/core/Mage/Shipping/Model/Carrier/Flatrate.php to app/code/local and to change them. In Flatrate.php -> public function collectRates change first line in it:
if (!$this->getConfigFlag('active')) {
to
if (!$this->getConfigFlag('active') || $request->getDestRegionCode() == 'xyz') {
and in Freeshipping.php -> public function collectRates change again this:
if (!$this->getConfigFlag('active')) {
to
if (!$this->getConfigFlag('active') || $request->getDestRegionCode() == 'abc') {
or something like this. Another solution is to add new setting for region/state in the configuration of the methods and then to add a check for it in app/code/core/Mage/Shipping/Model/Carrier/Abstract.php -> public function checkAvailableShipCountries.
