Insert a different shipping price at 'getOrderShippingCost' function

[immanueljl]

Hi, i am just a beginner and i try to create my own carrier module. So far its cool but i stack at this point. I know i can return any integer at "public function getOrderShippingCost($params, $shipping_cost)" as my shipping price. My problem is i have 3 carrier and i want a different cost each carrier. Here my full code:

 

class belvg_freightdelivery extends CarrierModule

{

    const PREFIX = 'belvg_fcd_';

 

    public $id_carrier;

 

    protected $_hooks = array(

        'header',

        'actionCarrierUpdate',

        'displayOrderConfirmation',

        'displayAdminOrder',

        'displayBeforeCarrier',

    );

 

    protected $_carriers = array( //HERE I PUT 3 CARRIER

        'Freight Company' => 'fcd',

        'Freight Company2' => 'fcd2',

        'Freight Company3' => 'fcd3',

    );

 

    public function __construct()

    {

        $this->name = 'belvg_freightdelivery';

        $this->module_key = '';

 

        parent::__construct();

 

        $this->displayName = $this->l('Delivery by freight company');

        $this->description = $this->l('If your customer choose “Delivery by freight company”, you get a text field for entering information to the freight company');

    }

It will be good if someone can help me. Thanks!

NOTE: i use prestashop 1.6

Just in case someone need the answer in future, you can get the carrier id for each carrier that being called getOrderShippingCostExternal function for by declaring public member variable of id_carrier for your module like so:

class CustomCarrier extends CarrierModule
{
    public $id_carrier;
}

In the Cart.php if it detect your module have id_carrier member variable it will set it with current carrier id being called the getOrderShippingCostExternal function for, so you could get it in your getOrderShippingCostExternal function like so:

public function getOrderShippingCostExternal($params)
{
    return calculateShippingCostForCarrierId($this->id_carrier);
}

Hi there, 

When I declare that variable, it doesn't seem to actually fill it with the value of the carrier, it just stays empty. 

When is the  getOrderShippingCostExternal  function actually called ? 

 

I need to hide one of the two carriers I created based on the postcode given by the user, so I use the  getOrderShippingCost function to return false to not display the carrier, which works perfectly fine in 1.7,but in 1.6 it just hides both my carriers, which is not what I want.

Any idea how I could fix that ? 

 

Thanks in advance for your response,

MD.

PS: This is my code inside  getOrderShippingCost

public function getOrderShippingCost($cart, $shipping_cost)

{

          $carrier = new Carrier(ID_CARRIER_I_WANT_TO_HIDE);

          $address = new Address($cart->id_address_delivery);

          $jsonFileLocation = Tools::file_get_contents("http://somelocation/postcodes.json"); 

          $allPostcodes = json_decode($jsonFileLocation, true);

          for($i = 0; $i < sizeof($allPostcodes["postcodes"]); $i++){

                    if($address->postcode == $allPostcodes["postcodes"][$i]){

                           return (float)$shipping_cost;

                    }

          }

          return false;

}
