You can check the email id for a specific website by using the below code.

<?php
namespace VendorModuelModel;

use MagentoCustomerApiAccountManagementInterface;
use MagentoStoreModelStoreManagerInterface;

class EmailExist {
    /**
     * @var AccountManagementInterface
     */
    protected $customerManagement;

    /**
     * @var StoreManagerInterface
     */
    protected $storeManager;

    /**
     * Data constructor.
     *
     * @param AccountManagementInterface $customerManagement
     * @param StoreManagerInterface $storeManager
     */
    public function __construct(
        AccountManagementInterface $customerManagement,
        StoreManagerInterface $storeManager
    ) {
        $this->customerManagement = $customerManagement;
        $this->storeManager = $storeManager;
    }

    /**
     *
     * @return bool
     */
    public function emailExistOrNot(): bool
    {
        $email = "testemail@email.com";
        $websiteId = (int)$this->storeManager->getWebsite()->getId();
        $isEmailNotExists = $this->customerManagement->isEmailAvailable($email, $websiteId);
        return $isEmailNotExists;
    }
}

Hope this article will help you to check customer email id’s existance.

You may have face this problem where sometimes you failed to show special character(s) in mini-cart in product name. But what shall one do when he/she has to show special characters like single quote, double quote in product title in minicart.

Well, all you need to do is to copy default.html file from the vendor directory and place it with the relevant path in the theme.

app/design/frontend/Magento/theme/Magento_Checkout/web/template/minicart/item/default.html

Below is the whole code you need to replace in the above file.

That’s it. Hope this article helped you to solve your programmatical problem.

We are going to add prefix word using the database operation.

– Login to Database & Check table ‘sales_sequence_meta’

In the above SC “meta_id” is:  ‘ 2 ‘  And after run the below query :

UPDATE ‘sales_sequence_profile’ SET ‘prefix’ = ‘HAZ’ WHERE ‘meta_id’ = 2;

That’s it!! Now when you will going to place an order, You will get the next increment Id Like ‘HAZ21050001′ by ‘HAZ’ prefix word.

Thank you.

If you have to upgrade your Magento version from 2.1.7 to 2.3.4 then follow the below steps.

Note: Please take the backup of your existing database and take a full backup.

After taking backup follow the below upgrade steps on the Magento root directory using the terminal.

Step 1 : php bin/magento maintenance:enable

Step 2 : Take backup using existing composer.json of your site’s Magento root folder

Step 3 : composer remove magento/product-community-edition –no-update

Step 4 : composer require magento/product-community-edition=2.3.4 –no-update

Step 5 : composer require –dev allure-framework/allure-phpunit:~1.2.0 friendsofphp/php-cs-fixer:~2.13.0 lusitanian/oauth:~0.8.10 magento/magento-coding-standard:~1.0.0 magento/magento2-functional-testing-framework:~2.3.14 pdepend/pdepend:2.5.2 phpunit/phpunit:~6.5.0 sebastian/phpcpd:~3.0.0 squizlabs/php_codesniffer:3.3.1 –sort-packages –no-update

Step 6 : composer remove –dev sjparkinson/static-review fabpot/php-cs-fixer –no-update

Step 7 : Open composer.json and add the below line in “autoload”: “psr-4” section in last.

"autoload": {
    "psr-4": {
        ...
        ...
        "Zend\Mvc\Controller\": "setup/src/Zend/Mvc/Controller/"
    },
    ...
}

Step 8 : composer update

Step 9 : php bin/magento cache:clean

Step 10 : rm -rf var/cache/* var/log/* var/page_cache/* var/session/* var/view_preprocessed/* generation/* pub/static/*

Step 11 : php bin/magento setup:upgrade

Step 12 : php bin/magento maintenance:disable

Thats it.

Now clean the cache and check your Magento version. It should be upgraded to 2.3.4

Generally, you can see luma theme container’s max-width is: 1280px

So in case, if you wish to change the main container max-width in your theme, Just override _theme.less file in your theme web/css/source/ folder and change max-width in below less variable. You don’t need to disturb any other CSS.

@layout__max-width: 1360px;

Note: I have tried the above solution in Magento 2.3.* and 2.4.* and I have made a custom theme based on the luma theme. It worked for me.

Hope the above solution will also help you in your programming journey.

While going through the logs, I noticed:

Message: Notice: Undefined offset: 0 in vendor/magento/module-customer/Model/ForgotPasswordToken/GetCustomerByToken.php on line 87

To get the solution, I followed the below steps.

Step 1). Override the block of reset password – Vendor/Module/etc/di.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="MagentoCustomerBlockAccountResetpassword" type="VendorModuleBlockCustomerAccountResetpassword" />
</config>

Step 2). Vendor/Module/Block/Customer/Account/Resetpassword.php

<?php

namespace VendorModuleBlockCustomerAccount;

class Resetpassword extends MagentoCustomerBlockAccountResetpassword
{
    public function __construct(
    MagentoFrameworkViewElementTemplateContext $context,
    MagentoCustomerModelSession $customerSession,  
    MagentoFrameworkObjectManagerInterface $objectManager,
    array $data = []
     ) {
        parent::__construct($context, $data);
        $this->customerSession = $customerSession;
        $this->_objectManager = $objectManager;
      }
	public function getResetPasswordLinkToken()
    {
        return $this->customerSession->getRpToken();         
    }

}

One of our clients was looking to add the Barcode using OrderIncrement id.

To achieve that I used picqer/php-barcode-generator library in Magento. You can follow the remaining steps only after installing the library.

Step 1: Create a Plugin and define that plugin di.xml. Use the below code and add it to the di.xml file.

<type name="MagentoSalesModelOrderPdfInvoice">
    <plugin name="barcodes_pdf_invoice" type="MagemonkeysBarcodesPluginInvoice" sortOrder="10" />
</type>

Step 2: Create a Invoice.php file under Plugin under this folder “app/code/Magemonkeys/Barcode/Plugin“.

<?php
/**
 * @category Print Barcode On Invoice PDF
 * @package  Magemonkeys_Barcodes
 * @author   Abbacus Team
 */
namespace MagemonkeysBarcodesPlugin;

use MagentoFrameworkAppConfigScopeConfigInterface;
use PicqerBarcodeBarcodeGeneratorPNG;

class Invoice
{
    /**
     * @var ScopeConfigInterface
     */
    private $scopeConfig;
    /**
     * @var MagentoSalesModelOrderInvoice
     */
    private $invoiceModel;
    
    /**
     * 
     * @param ScopeConfigInterface $scopeConfig
     * @param MagentoSalesModelOrderInvoice $invoiceModel
     */
    public function __construct(
        ScopeConfigInterface $scopeConfig,
        MagentoSalesModelOrderInvoice $invoiceModel
    ) {
        $this->scopeConfig = $scopeConfig;
        $this->invoiceModel = $invoiceModel;
    }
    
    /**
     * 
     * @param string $subject
     * @param object $page
     * @param string $text
     */
    public function beforeInsertDocumentNumber($subject, $page, $text)
    {
        $docHeader = $subject->getDocHeaderCoordinates();
        $image = $this->generateBarcode($text);
        $page->drawImage($image, $docHeader[2] - 150, $docHeader[1] + 20, $docHeader[2] , $docHeader[1] +55);
    }
    
    /**
     * 
     * @param string $text
     * @return Zend_Pdf_Resource_Image_Png
     */
    protected function generateBarcode($text)
    {
        $invoiceIncrement = $this->extractInvoiceNumber($text);
        $invoice = $this->invoiceModel->loadByIncrementId(trim($invoiceIncrement));
        $order = $invoice->getOrder();
        $orderIncrementId = $order->getIncrementId();
        $generator = new BarcodeGeneratorPNG;
        $image = new Zend_Pdf_Resource_Image_Png('data:image/png;base64,' . base64_encode($generator->getBarcode($orderIncrementId, $generator::TYPE_CODE_128)));
        return $image;
    }
    
    /**
     * 
     * @param string $text
     * @return string
     */
    protected function extractInvoiceNumber($text)
    {
        $array_of_words = explode("#", $text);
        return $array_of_words[1];
    }
}

Now, when you print the Invoice PDF, the barcode will be shown on the top of the PDF. Happy coding. 🙂

If you want to change the header logo only on the checkout page using XML, then follow the below instructions:

First, you should override the checkout_index_index.xml file in your theme and add the below code between the body.

<referenceBlock name="logo">
<arguments>
<argument name="logo_src" xsi:type="helper" helper="MagemonkeyCustomModHelperData::getLogo"></argument>
</arguments>
</referenceBlock>

Then, you need to create a helper or add the below function in your exiting helper file. (here I have created a new helper file in my module)

<?php
namespace MagemonkeyCustomModHelper;
class Data extends MagentoFrameworkAppHelperAbstractHelper
{
protected $_request;
public function __construct
(
MagentoFrameworkAppRequestHttp $request,
MagentoFrameworkViewAssetRepository $assetRepo
) {
$this->_request = $request;
$this->_assetRepo = $assetRepo;
}
public function getLogo()
{ 
return $this->_assetRepo->getUrl('images/checkout-logo.png');
}
}

*Note: I have tried this code in Magento 2.4.2
