Minicart no update with custom add to cart

[quienti]

Hi!

I created my custom module for add a product to my cart, if I use my controller with this form :

<form action="http://*********/test/cart/add/uenc/*******/product/471/" method="post" id="product_addtocart_form" novalidate="novalidate">

My product is in my cart, but minicart is not update, and change page not resolve this problem.

But, if I change my form link with magento controller like this :

<form action="http://*********/checkout/cart/add/uenc/*******/product/471/" method="post" id="product_addtocart_form" novalidate="novalidate">

It's work fine

In my controller, I have just change this

namespace Magento\Checkout\Controller\Cart
to this
namespace Test\Test\Controller\Cart;

@quienti Thank you for your question.
Please try creating a sections.xml file in the etc folder of your module and configure it according to your needs, for example:

<action name="test/cart/add">
    <section name="cart"/>
</action>

This would reload customer's minicart on each POST request to your controller. Basically, action node indicates controller path and section node defines which client-side content should be updated.
Caches have to be flushed for this change to apply.
You may use Magento/Checkout/etc/frontend/sections.xml for a reference.

@ishakhsuvarov - sections.xml will only work for Post request ? As in GET request it is not working. any solution for this.

[ishakhsuvarov]

@pankaj-pareek It is designed only to be used on a state-changing requests, which GET isn't.

@pankaj-pareek POST and PUT to be clear. Any code changing system state in GET request violates CQRS and needs to be reworked.

[pankaj-pareek]

Thanks for clarification. I will make changes in the flow to add products programmatically using post request.

Magetno 2.2.2 Xml Session doesn't work e.g
<action name="test/cart/add"> <section name="cart"/> </action>
. It works only with required e.g
<script> require([ 'Magento_Customer/js/customer-data' ], function (customerData) { setTimeout(function(){ customerData.reload(['cart']); }, 1000); }); </script>

is there a bug that it doesn't reload with sections.xml?

[orlangur]

@lano-vargas section should be enough if you access this action with post/put/delete http method.

@orlangur Thank you.

I am injecting the \Magento\Checkout\Model\Cart then:

    .....
    try {

        $_product = $this->productRepository->getById($productId);

        $this->_cart->addProduct($_product, $params);

        $this->_cart->save();

        $this->_messageManager->addSuccessMessage(__('You added '.$_product->getName().' to your shopping cart.'));

        // Perhaps here reload cart customer data E.G $this->_cart->reload('cart')

    }catch (\Exception $e){
        $this->_messageManager->addError($e->getMessage());
    }
   .....

Magento doesn't happen to have a method to reload customer data? E.G
$this->_cart->reload('cart') similar to requireJS
