Magento2 eCommerce Platforms

the best way is to work on your custom theme by modifying these files

/app/design/frontend/{Vendor}/{theme}/Magento_Checkout/layout/checkout_index_index.xml

To do this we need to work on the design area it is the easiest way 

firs Create new folder under your theme 

Folder Name: Magento_ConfigurableProduct\web\js

Copy this file "configurable.js" from this path

vendor/magento/module-configurable-product/view/frontend/web/js/configurable.js 

in the line 407 you need to modify this part

In this wiki we will find a way to use "==" equal in the email template, actually there is no equal in the email template itself but we can refer to a phtml file and pass a variable to it then use the if/equal in the phtml file to do this you can easily add this code to the template 

in the below example we will check if the payment method is bank transfer then we will write something

- Where does Magento Check the email frequency send

\vendor\magento\module-security\Model\SecurityChecker\Frequency.php

public function check($securityEventType, $accountReference = null, $longIp = null)
{

}

First of all you need to install Mageplaza Extension , you can find it here

https://github.com/mageplaza/magento-2-smtp

after you create O365 SMTP connector that you may use as smtp server to allow sending out emails as group

you need to override this class

vendor\mageplaza\module-smtp\Model\Config\Source\Authentication.php

change value of None from '' into 'smtp'.

then go to the configuration and choose None and click on Save

that's it :)

You need to use this in your constructer 

/**
 * @var Magento\Framework\Registry
 */
private $registry;

public function __construct(\Magento\Framework\Registry $registry)

{
    $this->registry = $registry;
}

then you can get the current category by this code

$category = $this->registry->registry('current_category');

you need to disable all these modules 

Magento include a base .gitignore file with the Magento Open Source project repository. See the latest Magento .gitignore file. If you need to add a file that is in the .gitignore list, you can use the -f (force) option when staging a commit:

Nice and clean one 

Caching plays an essential role in improving the page load time. In this article, I want to show you five blocks cache in Magento 2, or five approaches to caching, and when and how to use them. Interestingly, this article will cover both full page and block cache. Let’s explore each type of block cache together!

In case, cache_lifetime of the block is set to a number greater than 0, the block is cacheable

to cache any block, you need to override this function 

You can set the mode via command line

php bin/magento indexer:set-mode {realtime|schedule} [indexer-name]

“realtime” is equal to “Update on Save” and “schedule” is equal to “Update by Schedule”.
