Magento 2 - hide & disable add type product (Simple product … etc)

Question

On Magento 2, and product page, there's a list of product type,

I want to hide and disable and block a user to access an additional type of product,

for example: hide Configurable product and Bundle product and block the routes of it ( so, you can't add a configurable if you using the URL directly )

Answer 1

You can override the class \Magento\Catalog\Block\Adminhtml\Product using di.xml preference as describe below.

Assume you are using a custom module name "Company_MyModule"

step 1: create di.xml under YOUR-MAGENTO-ROOT/app/code/Company/MyModule/etc/adminhtml

File: YOUR-MAGENTO-ROOT/app/code/Company/MyModule/etc/adminhtml/di.xml

<?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\Catalog\Block\Adminhtml\Product" type="Company\MyModule\Block\Adminhtml\Product" />                
</config>

step 2: Create the class Product.php under YOUR-MAGENTO-ROOT/app/code/Company/MyModule/Block/Adminhtml

File : YOUR-MAGENTO-ROOT/app/code/Company/MyModule/Block/Adminhtml/Product.php

<?php

namespace Company\MyModule\Block\Adminhtml;

class Product extends \Magento\Catalog\Block\Adminhtml\Product
{
     protected function _getAddProductButtonOptions()
    {
        /* var Array $arrAlowedTypes */     
        $arrAlowedTypesIds = array('simple');
        $splitButtonOptions = [];
        $types = $this->_typeFactory->create()->getTypes();
        uasort(
            $types,
            function ($elementOne, $elementTwo) {
                return ($elementOne['sort_order'] < $elementTwo['sort_order']) ? -1 : 1;
            }
        );

        foreach ($types as $typeId => $type) {
            if(in_array($typeId,$arrAlowedTypesIds)) {              
             $splitButtonOptions[$typeId] = [
                'label' => __($type['label']),
                'onclick' => "setLocation('" . $this->_getProductCreateUrl($typeId) . "')",
                'default' => \Magento\Catalog\Model\Product\Type::DEFAULT_TYPE == $typeId,
             ];
          }
        }

        return $splitButtonOptions;
    }
}

Step 3: Run DI compile

sudo php bin/magento setup:di:compile

Answer 2

To disable access from direct URL.

You can override the class \Magento\Catalog\Block\Adminhtml\Product using di.xml preference as described below.

Assume you are using a custom module name "Company_MyModule"

step 1: create di.xml under YOUR-MAGENTO-ROOT/app/code/Company/MyModule/etc/adminhtml

File: YOUR-MAGENTO-ROOT/app/code/Company/MyModule/etc/adminhtml/di.xml

<?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\Catalog\Controller\Adminhtml\Product\NewAction" 
    type="Company\My-Module\Controller\Adminhtml\Product\NewAction" />   

</config>

step 2: Create the class NewAction.php under YOUR-MAGENTO-ROOT/Company/MyModule/Controller/Adminhtml/

File : YOUR-MAGENTO-ROOT/Company/MyModule/Controller/Adminhtml/NewAction.php

<?php

namespace Company\MyModule\Controller\Adminhtml\Product;

class NewAction extends \Magento\Catalog\Controller\Adminhtml\Product\NewAction
{

   public function execute()
    {
        if (!$this->getRequest()->getParam('set')) {
            return $this->resultForwardFactory->create()->forward('noroute');
        }

         $arrAlowedTypesIds = array('simple');
         $typeId = $this->getRequest()->getParam('type');
         if(!in_array($typeId,$arrAlowedTypesIds)) {    
            return $this->resultForwardFactory->create()->forward('noroute');
         }

         return parent::execute();        

    }

}
