now to hide add to cart and price for specific categories my code is

> namespace PME\Hideprice\Plugin

<?php

declare(strict_types=1);

namespace PME\Hideprice\Plugin;

use Magento\Framework\App\Http\Context;
use Magento\Customer\Model\Context as CustomerContext;
use Magento\Framework\App\Config\ScopeConfigInterface;
use Magento\Store\Model\ScopeInterface;
use PME\Hideprice\Helper\Data as Helper;

/**

class IsSalablePlugin
{
    /**

    protected $scopeConfig;

    /**

     * Customer session is not initialized yet
     *

     */
    protected $context;

    protected $_initialValue = false;

    const DISABLE_ADD_TO_CART = 'pme_hideprice/general/catalog_frontend_disable_add_to_cart_for_guest';

    /**

     */
    public function __construct(
        ScopeConfigInterface $scopeConfig,
        Context $context,
        Helper $helper
    ) {
        $this->scopeConfig = $scopeConfig;
        $this->context = $context;
        $this->_helper = $helper;
    }

    /**
     * 
     */
    public function afterIsSalable(
        \Magento\Catalog\Model\Product $subject,
        $result
    )
    {

        $categories_main=$this->_helper->arrayData();
        $categories = array_pop($categories_main);
        $categoriess[] = $categories;

        $allowed= $this->_helper->getCurrentCategory();
        $result=array_intersect($categoriess,$allowed);

        if (!empty($result)) {

        $this->initialValue = $result;
        $scope = ScopeInterface::SCOPE_STORE; 
            if($this->_helper->getIsEnable()) {
                if ($this->scopeConfig->getValue(self::DISABLE_ADD_TO_CART, $scope)) {
                    if ($this->_helper->isCustomerLoggedIn()) {
                        return true;
                    }
                    return false;
                } 
                return true; 
            }    
            return $result;   
        }
    }

    public function afterGetIsSalable (
        \Magento\Catalog\Model\Product $subject,
        $result
    ) {

        $categories_main=$this->_helper->arrayData();
        $categories = array_pop($categories_main);
        $categoriess[] = $categories;

        $allowed= $this->_helper->getCurrentCategory();
        $result=array_intersect($categoriess,$allowed);

        if (!empty($result)) {

            $scope = ScopeInterface::SCOPE_STORE; 
            if($this->_helper->getIsEnable()) {
                if ($this->scopeConfig->getValue(self::DISABLE_ADD_TO_CART, $scope)) {
                    if ($this->_helper->isCustomerLoggedIn()) {
                        return true;
                    }
                    return $this->initialValue;
                }
                return true;  
            } 
            return $result;
         }
    }    
}

now for this my Helper is

PME\Hideprice\Helper

<?php
namespace PME\Hideprice\Helper;

use Magento\Framework\App\Helper\AbstractHelper;
use Magento\Framework\App\Config\ScopeConfigInterface;
use Magento\Framework\App\Http\Context;
use Magento\Customer\Model\Context as CustomerContext;

class Data extends AbstractHelper
{

    protected $getarray;

    /**
     * Scope config
     *
     * @var ScopeConfigInterface
     */
    protected $scopeConfig;

    /**
     * HTTP Context
     * Customer session is not initialized yet
     *
     * @var Context
     */

    protected $context;

     /**
     * SalablePlugin constructor.
     *
     * @param ScopeConfigInterface $scopeConfig ScopeConfigInterface
     * @param Context              $context     Context
     * @param \Magento\Framework\Registry $registry,
     */

    public function __construct(
        ScopeConfigInterface $scopeConfig,
        Context $context,
        \Magento\Framework\App\Helper\Context $helpercontext,
        \Magento\Customer\Model\Session $_customerSession,
        \Magento\Framework\Registry $registry
    ) {

        $this->_customerSession = $_customerSession;
        $this->scopeConfig = $scopeConfig;
        $this->context = $context;
        $this->_registry = $registry;
        parent::__construct($helpercontext);
    }

    public function isCustomerLoggedIn() {

        return $this->context->getValue(CustomerContext::CONTEXT_AUTH);
        //to check login mean that to check that the customer is logged in or not
    }

    public function getIsEnable(){
        return $this->scopeConfig->getValue('pme_hideprice/general/enabled', 
                                            \Magento\Store\Model\ScopeInterface::SCOPE_STORE);
    }

    public function isEnabled($scope = ScopeConfigInterface::SCOPE_TYPE_DEFAULT)
    {
        return $this->scopeConfig->isSetFlag(
            'pme_hideprice/general/enabled',
            $scope
        );
    }

    public function arrayData(){

            $getarray = $this->scopeConfig->getValue('pme_hideprice/general/category',
            \Magento\Store\Model\ScopeInterface::SCOPE_STORE);
            return explode ( ',',$getarray);

    }

    /**
 * Return catalog current category object
 *
 * @return \Magento\Catalog\Model\Category
 */

public function getCurrentCategory()
{
    return $this->_registry->registry('current_category');
}



}

now in this the issue is I'm using registry and the registry only get the current product category.. so its not works properly. enter image description here

You can use ProductRepository to get all Products Id in Magento 2.

Maybe this code will useful for you:

class Product extends Action
{
    private $productRepository;
    /**
     * @var SearchCriteriaBuilder
     */
    private $searchCriteriaBuilder;

    public function __construct(
        Context $context,
        ProductRepositoryInterface $productRepository,
        SearchCriteriaBuilder $searchCriteriaBuilder
    ) {
        parent::__construct($context);
        $this->productRepository = $productRepository;
        $this->searchCriteriaBuilder = $searchCriteriaBuilder;
    }

    public function execute()
    {
        $this->getResponse()->setHeader('Content-Type', 'text/plain');
        $criteria = $this->searchCriteriaBuilder->create();
        $products = $this->productRepository->getList($criteria);
        foreach ($products as $product) {
            $this->getResponse()->appendBody(sprintf(
                    "(%d)",
                    $product->getId())
            );
        }
    }
}

Cheers!

The problem is this:

$allowed= $this->_helper->getCurrentCategory();
$result=array_intersect($categoriess,$allowed);

$allowed is not an array. It's an instance of the category model.
you can change to this:

$result=array_intersect($categoriess, [$allowed->getId()]);
  • now it gives me the further problem Fatal error: Uncaught Error: Call to a member function getId() on null in C:\xampp\htdocs\magento\app\code\PME\Hideprice\Plugin\IsSalablePlugin.php:71 Stack trace – Asad Khan Dec 21 '18 at 10:05
