hiding products for guest user M2

Question

I have one question about showing products. I dont want to show products for guest user. Even when they search for those products they will not get that. Only logged in user will get those.

Can anyone give me some tips how we can implement this?

Answer 1

You may use a plugin after Magento\Catalog\Model\Product::getVisibility() and set the return value to Magento\Catalog\Model\Product\Visibility::VISIBILITY_NOT_VISIBLE if you have a guest user (i.e. the customer is not logged in) and your product attribute is set. Your custom attribute needs to be available in product lists otherwise loading a specific product collection could miss it.

Answer 2

If customer is not logged-in you can restrict customer from category and product page.

Check the following module

vendor/magento/module-website-restriction/Observer/RestrictWebsite.php

You can add custom controller path in "webrestrictions.xml" if you override this file in your module

vendor/magento/module-website-restriction/etc/webrestrictions.xml

Alternate solution you can use before Plugin for below class for execute method

vendor/magento/module-catalog/Controller/Product/View.php
vendor/magento/module-catalog/Controller/Category/View.php

Answer 3

You can use events in this approach

event name = catalog_block_product_list_collection

in the execute function you can remove all products like this

add events.xml to your module

etc/frontend/events.xml

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="catalog_block_product_list_collection">
        <observer instance="{vendor}\{module}\Observer\Frontend\Catalog\BlockProductListCollection" name="{vendor}_{module}_observer_frontend_catalog_blockproductlistcollection_catalog_block_product_list_collection"/>
    </event>
</config>

and this code to your observer file

/app/code/{Vendor}/{Module}/Observer/Catalog/BlockProductListCollection.php

<?php

namespace {Vendor}\{Module}\Observer\Catalog;

class BlockProductListCollection implements \Magento\Framework\Event\ObserverInterface
{

    public function execute(
        \Magento\Framework\Event\Observer $observer
    ) {

        // if(customer is not loggedin) 
    $collection = $observer->getEvent()->getCollection();
        foreach ($collection as $k => $product){
                 $collection->removeItemByKey($k);
        }

    }
}
