How to apply the Security Patch in Magento?


Magento is a flexible, customizable open-source platform that has a huge number of inbuilt functionalities. Apart from having these advantages of open-source software, Magento has some drawbacks related to security threats and vulnerabilities. To resolve these threats Magento releases security patches from time to time.

Security patches contain security fixes only. They are designed to make the upgrade process faster and easier. There are two ways to apply a security patch in Magento using:

  • Command Line
  • Composer

Follow the below steps to apply security patches using Composer:

  1. Enable Maintenance Mode: It will prevent from customers placing unfulfillable orders.
    php bin/magento maintenance:enable
  2. Check running Cron Jobs: Wait for the currently working cron jobs. Once they are completed, turn off the services.
  3. Execute Composer Command: Security patches use the Composer naming convention 2.3.3-px. Use Composer to specify a patch.
    composer require magento/product-community-edition=2.3.3-p1 --no-update
  4. Apply updates: This will update changes from the composer.json file.
    composer update
  5. Clean the Magento cache:
    php bin/magento cache:flush
  6. Clear the var/ and generated/ subdirectories:
    rm -rf generated/* var/cache/* var/page_cache/*
  7. Update the database schema and data:
    php bin/magento setup:upgarde
  8. Disable maintenance mode:
    php bin/magento maintenance:disable
  9. (Optional) Restart Varnish:
    service varnish restart

How to call a Phtml file in another Phtml file?

Sometimes while developing new pages we need to use some blocks repetitively and for this, there are multiple options in Magento to call a block in another block. But here we are going to discuss a specific way to call a Phtml file from another Phtml file. For this, you need to open the Phtml file in which you want to call another Phtml and the below code: $this->getLayout()->createBlock("Magento\Framework\View\Element\Template")->setTemplate("MageInsight_ModuleName::template.phtml")->toHtml(); In this, you can change the block class with your block class OR you can use the same one if you don't have any block class to be included in it. If you want to pass a variable or call any function of your block in phtml then you can use the below code: $customBlock = $this->getLayout()->createBlock("Magento\Framework\View\Element\Template"); $customBlock->functionName(); $customBlock->setTemplate("MageInsight_ModuleName::template.ph

Disable Hover on main menu and make it work on click

The main menu in an eCommerce website holds significant importance as it serves as the primary navigational tool for users to explore and access various sections, products, and features of the online store. The main menu helps users discover products, services, and content they might not have been aware of. By presenting various categories and sections prominently, the menu can drive users to explore different parts of the website, increasing the chances of making a sale.

How to add a dynamic homepage in Magento 2?

Magento provides the ability to have multiple homepages or a homepage with dynamic blocks that alter based on demand. However, there may be times when different homepages must be displayed based on customer groups/segments. This is possible with the dynamic block functionality, which is available in the Enterprise and Cloud editions. However, there is a constraint in that you have to maintain numerous blocks for multiple customer groups/segments. In that situation, you can alter the default functionality by using the code below: Step 1: Create a plugin for "Magento\Cms\Controller\Index\Index" by adding the below code in your module di.xml file. <type name="Magento\Cms\Controller\Index\Index"> <plugin name="dynamicHomepage" type="Mageinsight\Module\Plugin\DynamicHomepage" sortOrder="1"/> </type> Step 2: Add the plugin file as below: <?php namespace Mageinsight\Module\Plugin; use Magento\Framework\App\Config;
