Magento 2: How to Check if a Customer is Logged in?

Samdoit Infotech - February 20, 2024

As Magento 2 store owner, you may want to treat logged in and non-logged in customers differently. For example, you may want to offer exclusive features or discounts to logged in customers only. To implement this, you first need to confirm whether a Magento 2 customer is logged in or not?

Methods To Check If A Customer Is Logged-In In Magento 2

There are 2 ways you can check this. By injecting class and by using object manager. Although the 2nd method (object manager) is not recommended, it’s still used as an alternative.

Method 1: By Injecting Class (Dependency Injection)

In this method, first, you need to inject the following class in the constructor method:

/Magento/Customer/Model/Session

protected $_session;

    public function __construct(
        ...
        \Magento\Customer\Model\Session $session,
        ...
    ) {
        ...
        $this->_session = $session;
        ...
    }

Then in your class, use the following code in any function to check if the customer is logged in or not:

if ($this->_session->isLoggedIn()) {
        // Customer is logged

Magento 2 Customize the search result

Samdoit Infotech - February 18, 2024

With Advanced Content Manager for Magento 2, it’s possible to index and make your content searchable.

The default catalog search layout is overridden by our extension, in order to add our results to the search.
The extension is adding a Result Search Block into the Catalog Search Result page layout:

Samdoit/ContentManager/view/frontend/layout/catalogsearch_result_index.xml

<page xmlns:xsi="..." layout="2columns-left" xsi:noNamespaceSchemaLocation="..."> 
<body> 
<referenceContainer name="content"> 
<block class="Samdoit\ContentManager\Block\Search\Result" name="search.content.result" after="search.result" template="Samdoit_ContentManager::content/search/result.phtml" cacheable="false"> 
<referenceContainer> 
<body> 
<page>

The Result Block retrieves the current query and create the search filter. The block will load a ContentList Collection from the ids retrieved in the results.

This block has the following child:

<block class="Samdoit\ContentManager\Block\Content\Widget\ContentList" name="search_content_result_list"

Magento 2 How to Add Product To Cart With Custom Price

Samdoit Infotech - February 16, 2024

With the support of seamless customization and integrations, Magento 2 e-commerce stores can serve excellent experiences to customers. In many cases, the store owners are willing to allow the shoppers to add the product to the cart with a custom price.

Frequently, the store owner is prepared to set a fixed product pricing even if the consumer selects various options/add-ons from the front end for all or some specific products. Instead of manually changing all store products, we’ll need to manually code to override all store product prices with your preferred custom price.

In this article, I will instruct you to set a custom price of the product when adding the product to the cart by using Observe.

Let’s explore two straightforward steps below!

Step 1: Create Events/xml File

Firstly, you need to create events/xml in the folder Mageplaza/HelloWord/etc/frontend and use event checkout_cart_product_add_after

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Magento 2: Get all shopping cart items, subtotal, grand total, billing & shipping address

Samdoit Infotech - February 16, 2024

This article shows how to get shopping cart items/products, subtotal and grand total of cart, and shipping and billing address entered while doing checkout in Magento 2.

I will be using both Dependency Injection (DI) and Object Manager in the below example code.

Using Object Manager

– Get products id, name, price, quantity, etc. present in your cart.
– Get number of items in cart and total quantity in cart.
– Get base total price and grand total price of items in cart.
– Get billing and shipping addresses entered during checkout.

Get all items information in cart

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$cart = $objectManager->get('\Magento\Checkout\Model\Cart'); 

// retrieve quote items collection
$itemsCollection = $cart->getQuote()->getItemsCollection();

// get array of all items what can be display directly
$itemsVisible = $cart->getQuote()->getAllVisibleItems();

// retrieve quote items array
$items = $cart->getQuote()->getAllItems();

foreach($items as $item)

vTiger CRM

VtigerCRM - Sorry! Attempt to access restricted file.

Samdoit Infotech - February 13, 2024

The most likely cause for the vTiger error “Sorry! Attempt to access restricted file.” is the $root_directory value in the ‘config.inc.php’ is incorrect or misspelled.

In order to correct it follow the steps below:

Go to your vTigerCRM directory
Open “config.inc.php” with your favorite text editor

MySQL - SQLSTATE[HY000] [2054] The server requested authentication method unknown to the client (solution)

Samdoit Infotech - September 18, 2022

The default MySQL 8 auth plugin is auth_socket, which causes the error "SQLSTATE[HY000] [2054] The server requested authentication method unknown to the client" when an application is attempting to log in to the database with a password. Let's go through the steps to fix this.

Step 1

Login to the mysql server in sudo mode as the root user and supply any required passwords.

sudo mysql -u root -p

Step 2

Now run the following ALTER USER command, replacing root with your database user and password if your password.

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';

Now run:

FLUSH PRIVILEGES;

Now exit the MySQL server:

exit;

Step 3

You may need to restart the mysql services for the changes to take effect:

sudo service mysql restart

Eloquent or Fluent random row

Samdoit Infotech - June 15, 2021

How can I select a random row using Eloquent or Fluent in the Laravel framework?

I know that by using SQL, you can do order by RAND(). However, I would like to get the random row without doing a count on the number of records prior to the initial query.
