I'm trying to customize a Magento 2.1 cart page both by overriding the Block Cart and accessing some of the overridden elements in a new phtml template.

I hit a roadblock after overriding the Cart block however, as it appears the overridden block in never loading any cart form.phtml, custom or otherwise.

I have created the override by creating the app/code/Vendor/Module/Block/Cart.php file that extends \Magento\Checkout\Block\Cart

<?php
namespace Vendor\Module\Block;

use Magento\Framework\View\Element\Template;

class Cart extends \Magento\Checkout\Block\Cart {
    public function getContinueShoppingUrl() {
        return 'http://externalurl/from/config';
    }
}

I have also created app/code/Vendor/Module/etc/di.xml with the configuration 

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
  <preference for="Magento\Checkout\Block\Cart" type="Vendor\Module\Block\Cart" />
</config>

I know that the overridden block is at least loading, as I can get output from echoing items in the constructor and there appear to be no other errors in the log. However, when I go to the /checkout/cart/ page, where I expect the checkout details to load I get nothing - just the typical header and footer elements surrounding a blank page.

Any idea what I'm missing here?

  • please put the code of "Cart.php" file which you override. – Abhishek Panchal Mar 14 '17 at 16:13
  • Add this line after your namespace line in block file. use Magento\Framework\View\Element\Template; hope it works – Abhishek Panchal Mar 14 '17 at 16:27
  • No luck. Added the line, flushed my cache, but still blank. – KMan2012 Mar 14 '17 at 16:33
  • Keep only Block file. I dont think you required di.xml file to override Block. remove "di.xml" file and try again. – Abhishek Panchal Mar 14 '17 at 16:35
  • I removed the di.xml file and the page definitely loads, but I do not believe that it is being overridden. Maybe this is too crude a check, but when I define a constructor and put a 'die' in it, nothing happens unless the di.xml file is configured. – KMan2012 Mar 14 '17 at 16:43

In overriding the Cart, the template files are being searched for in the relative path of the new Module, instead of the parent module. The quick-and-dirty fix I came up with is to copy the contents of the module-checkout's /view/templates/ into /Vendor/Module/view/frontend/templates/

I suspect there are cleaner ways of doing this, but this method appears functional.

  • If you just want to change continue shopping url then just use plugin on that block and create afterGetContinueShoppingUrl() method in it. – Zefiryn Mar 14 '17 at 18:31
