Retrieve $_POST value in ActionCarrierProcess hook

[Lwack]

Hello,

I've developped a small Carrier module to add delivery options with checkboxes.

I'm displaying the checkboxes with the DisplayCarrierExtraContent hook.

My problem is I don't know how to retrieve the $_POST values from the form. My module hookActionCarrierProcess method is correctly called, but it seems that the $_POST variable is empty (dumping it is showing [ ]). I've tried with Tools::getValue but obviously it returns false too.

When I press the submit button after selecting my carrier and checking some options, it seems that the $_POST values are correctly sent but the server responds with the following HTTP code: 302 Moved Temporarly.  What's weird is that submitting the form does trigger my code from the hookActionCarrierProcess  method.

 

Why is $_POST value empty when hookActionCarrierProcess  is called ?

Is there another way to send the form values (the checkboxes) to the hookActionCarrierProcess  method ?

 

I hope I am clear enough.

Thanks a lot for your help

Use ajax to send input field data from carrier extra content to a front controller of your module. Have the front controller to save the data to database. Read the data from database during later stages of the checkout process.

That should work indeed. Though I'm still curious why $_POST is empty when hookActionCarrierProcess is triggered...

Did you make it work?

Can you provide an example of how you are displaying your carriers on the delivery process? I'm having problems myself with the radio button as well.

Thank you

I ended up overriding OrderController::displayAjaxselectDeliveryOption in my module. From there you can access Tools::getValue('your_value')

 

<?php

// modules/MyModule/override/controllers/front/OrderController.php

class OrderController extends OrderControllerCore {
    public function displayAjaxselectDeliveryOption()
    {
        $cart = $this->cart_presenter->present(
            $this->context->cart
        );
        
        if ($this->context->cart->id_carrier == Configuration::get('MY_DELIVERY_CARRIER_ID')) {
            // Setting the options here            
        }

        ob_end_clean();
        header('Content-Type: application/json');
        $this->ajaxDie(Tools::jsonEncode(array(
            'preview' => $this->render('checkout/_partials/cart-summary', array(
                'cart' => $cart,
                'static_token' => Tools::getToken(false),
            ))
        )));
    }
}
