Hide Admin Menu Based on Store Default Country

Question

I need help on hiding the Customer Feedback - Article Menu if the default country is not JP.

My code is not working.

Plugin/RemoveCustomerFeedback.php

<?php

namespace Thecoachsmb\Mymodule\Plugin;

class RemoveCustomerFeedbackMenu
{
    protected $_request;
    protected $_authSession;

    public function __construct(
        \Magento\Framework\App\RequestInterface $request,
        \Magento\Backend\Model\Auth\Session $authSession
    ) {
        $this->_request = $request;
        $this->_authSession = $authSession;
    }

    public function afterGetMenu(
        \Magento\Backend\Model\Menu\Builder $subject,
        \Magento\Backend\Model\Menu $menu
    ) {
        $defaultCountry = $this->_authSession->getUser()->getDefaultCountry();
        if ($defaultCountry != 'JP') {
            $menu->remove('Thecoachsmb_Mymodule::customerfeedback');
        }
        return $menu;
    }
}

Answer 1

When creating the plugin for a class function, there must be two conditions fulfilled:

• The class name for which we are creating plugin must be same in the class mentioned in <type name=""> section in di.xml file and in the the plugged-in function in plugin class.
• The plugged-in function name must exist in the original class.

I checked the \Magento\Backend\Model\Menu\Builder class and could not find getMenu() function in this class.

Please verify that:

• You are creating plugin for the correct class
• The function you are trying to create plugin must be present in the original class.

After amount of time researching the solution of this. I realized that creating a custom menu was the best solution. Please refer to Menu not showing for custom role in custom module
