Successful e-commerce store demands to provide better user experience to grow their sales by offering and managing various payment methods at checkout page according to the needs of the specific customer as every customer has different demands. For example, the merchant which offers the cash on delivery for the local region may not be offered to international customers; In some cases, payment gateway requires certain taxes and fees for the different part which cannot be borne by the merchant.TO solve those issues, it has become vital for Magento store owners to optimize their payment methods according to different customer groups

To enable the payment process between customers and Magento store, we can restrict the payment methods by different customers groups by following the steps below.

1. Create an events.xml in : /app/code/Magemonkeys/PaymentMethod/etc

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
 <event name="payment_method_is_active">
 <observer name="Magemonkeys_PaymentMethod_DisabledPgByCustomergroup" instance="MagemonkeysPaymentMethodObserverDisabledPgByCustomergroup" />
 </event>
</config>

2. Create an DisabledPgByCustomergroup.php in : /app/code/Magemonkeys/PaymentMethod/Observer

<?php
namespace MagemonkeysPaymentMethodObserver;
use MagentoFrameworkEventObserverInterface;
use MagentoFrameworkAppRequestDataPersistorInterface;
use MagentoFrameworkAppObjectManager;

class DisabledPgByCustomergroup implements ObserverInterface
{
 
 public function execute(MagentoFrameworkEventObserver $observer)
 { 
    $helper = MagentoFrameworkAppObjectManager::getInstance()->get('MagemonkeysPaymentMethodHelperData'); 
    if($helper->isEnable()){
      $customer_grp = $helper->isActiveGroup(); 
      $result = $observer->getEvent()->getResult();
      $method_instance = $observer->getEvent()->getMethodInstance();
      $quote = $observer->getEvent()->getQuote(); 
       if (null !== $quote && $quote->getCustomerGroupId() != 'CUSTOMER_GROUP_ID') { 
        if ($method_instance->getCode() == 'PAYMENT_METHOD_CODE') {
          $result->setData('is_available', false);
        } 
      }
    }
  }
} 
?>

By following the above steps, you can restrict the payment methods in Magento 2 store.
If you have any doubt regarding the above method, feel free to ask me the comment section.

I would be happy to help you.

In this article, I will guide you on, how to add VAT and Company Number in invoice and shipment PDF in Magento 2?

Follow the below steps:

You need to override two models in custom extension.

I assume you know about how to override model.

Step 1

Create di.xml file in your module’s etc folder and put below code in it

<?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="MagentoSalesModelOrderPdfInvoice" type="[vendername][modulename]ModelOrderPdfinvoice" />
 <preference for="MagentoSalesModelOrderPdfShipment" type="[vendername][modulename]OrderPdfshipment" />
</config>

Step 2

Create new model file Pdfinvoice.php in your Model/Order folder and put below code in it.

<?php
namespace [vendername][modulename]ModelOrder;
class Pdfinvoice extends MagentoSalesModelOrderPdfInvoice
{
 /**
 * Return PDF document
 *
 * @param array|Collection $invoices
 * @return Zend_Pdf
 */
 public function getPdf($invoices = [])
 {
 $this->_beforeGetPdf();
 $this->_initRenderer('invoice');

 $pdf = new Zend_Pdf();
 $this->_setPdf($pdf);
 $style = new Zend_Pdf_Style();
 $this->_setFontBold($style, 10);

 foreach ($invoices as $invoice) {
 if ($invoice->getStoreId()) {
 $this->_localeResolver->emulate($invoice->getStoreId());
 $this->_storeManager->setCurrentStore($invoice->getStoreId());
 }
 $page = $this->newPage();
 $order = $invoice->getOrder();
 /* Add image */
 $this->insertLogo($page, $invoice->getStore());
 /* Add address */
 $this->insertAddress($page, $invoice->getStore());
 /* Add head */
 $this->insertOrder(
 $page,
 $order,
 $this->_scopeConfig->isSetFlag(
 self::XML_PATH_SALES_PDF_INVOICE_PUT_ORDER_ID,
 MagentoStoreModelScopeInterface::SCOPE_STORE,
 $order->getStoreId()
 )
 );
 
 /* Add document text and number */
 $this->insertDocumentNumber($page, __('Invoice # ') . $invoice->getIncrementId());
 /* Add table */
 $this->_drawHeader($page);
 /* Add body */
 foreach ($invoice->getAllItems() as $item) {
 if ($item->getOrderItem()->getParentItem()) {
 continue;
 }
 /* Draw item */
 $this->_drawItem($item, $page, $order);
 $page = end($pdf->pages);
 }
 /* Add totals */
 $this->insertTotals($page, $invoice);
 if ($invoice->getStoreId()) {
 $this->_localeResolver->revert();
 }
 $this->_drawFooter($page);
 }
 $this->_afterGetPdf();
 return $pdf;
 }

 protected function _drawFooter(Zend_Pdf_Page $page)
 {
 $this->y = 50; 
 $page->setFillColor(new Zend_Pdf_Color_RGB(1, 1, 1));
 $page->setLineColor(new Zend_Pdf_Color_GrayScale(0.5));
 $page->drawRectangle(25, $this->y, 570, $this->y -30);
 $page->setLineWidth(0.5);

 $page->setFillColor(new Zend_Pdf_Color_RGB(0.1, 0.1, 0.1));
 $this->_setFontRegular($page, 10);
 $this->y -=16;
 $page->drawText(__('VAT # xxxxxxxx'), 220, $this->y, 'UTF-8');
 $page->drawText(__('Company # xxxxxxxxx'), 320, $this->y, 'UTF-8');

 } 
}

Step 3

Create another new model file Pdfshipment.php in your Model/Order folder and put below code in it.

<?php
namespace [vendername][modulename]ModelOrder;
class Pdfshipment extends MagentoSalesModelOrderPdfShipment
{
 /**
 * Return PDF document
 *
 * @param MagentoSalesModelOrderShipment[] $shipments
 * @return Zend_Pdf
 */
 public function getPdf($shipments = [])
 {
 $this->_beforeGetPdf();
 $this->_initRenderer('shipment');

 $pdf = new Zend_Pdf();
 $this->_setPdf($pdf);
 $style = new Zend_Pdf_Style();
 $this->_setFontBold($style, 10);
 foreach ($shipments as $shipment) {
 if ($shipment->getStoreId()) {
 $this->_localeResolver->emulate($shipment->getStoreId());
 $this->_storeManager->setCurrentStore($shipment->getStoreId());
 }
 $page = $this->newPage();
 $order = $shipment->getOrder();
 /* Add image */
 $this->insertLogo($page, $shipment->getStore());
 /* Add address */
 $this->insertAddress($page, $shipment->getStore());
 /* Add head */
 $this->insertOrder(
 $page,
 $shipment,
 $this->_scopeConfig->isSetFlag(
 self::XML_PATH_SALES_PDF_SHIPMENT_PUT_ORDER_ID,
 MagentoStoreModelScopeInterface::SCOPE_STORE,
 $order->getStoreId()
 )
 );
 /* Add document text and number */
 $this->insertDocumentNumber($page, __('Packing Slip # ') . $shipment->getIncrementId());
 /* Add table */
 $this->_drawHeader($page);
 /* Add body */
 foreach ($shipment->getAllItems() as $item) {
 if ($item->getOrderItem()->getParentItem()) {
 continue;
 }
 /* Draw item */
 $this->_drawItem($item, $page, $order);
 $page = end($pdf->pages);
 }
 if ($shipment->getStoreId()) {
 $this->_localeResolver->revert();
 }
 $this->_drawFooter($page);
 }
 $this->_afterGetPdf();
 return $pdf;
 }

 protected function _drawFooter(Zend_Pdf_Page $page)
 {
 $this->y = 50; 
 $page->setFillColor(new Zend_Pdf_Color_RGB(1, 1, 1));
 $page->setLineColor(new Zend_Pdf_Color_GrayScale(0.5));
 $page->drawRectangle(25, $this->y, 570, $this->y -30);
 $page->setLineWidth(0.5);

 $page->setFillColor(new Zend_Pdf_Color_RGB(0.1, 0.1, 0.1));
 $this->_setFontRegular($page, 10);
 $this->y -=16;
 $page->drawText(__('VAT # xxxxxxxxx'), 220, $this->y, 'UTF-8');
 $page->drawText(__('Company # xxxxxxxxx'), 320, $this->y, 'UTF-8');

 }
}

If you want to get bundle child product description on bundle parent product detail page in ‘DETAILS’ tab.

You can override attribute.phtml file in your theme and put below code at bottom of the file

<?php 
if($_product->getTypeId() === 'bundle'){ 
 $objectManager = MagentoFrameworkAppObjectManager::getInstance();
 $product = $objectManager->get('MagentoCatalogModelProduct')->load($_product->getId()); 
 $selectionCollection = $product->getTypeInstance(true)->getSelectionsCollection($product->getTypeInstance(true)->getOptionsIds($product),$product);
 foreach ($selectionCollection as $proselection) { 
 $option_product = $objectManager->get('MagentoCatalogModelProduct')->load($proselection->getId()); ?>
 <div class="bundle-item-description"> 
 <h3><?php echo $option_product->getName() ?></h3>
 <p><?php echo $option_product->getDescription(); ?></p>
 </div>
 <?php }
} ?>

In this article, I will guide you on how to use a plugin to block Override in Magento 2.

Add di.xml file in app/code/Magemonkeys/HelloWorld/etc/ and copy the following code in it:

<?xml version="1.0"?>
 
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="MagentoCatalogBlockProductView">
        <plugin name="magemonkeys-helloworld-product-block" type="MagemonkeysHelloWorldPluginProductPlugin" sortOrder="5" />
    </type>
</config>

Here enable all the methods containing before, after, and around methods.

• Firstly, beforeGetProduct method will be active.
• Next, aroundGetPrduct will be active.
• Finally, afterGetProduct method will be active. You can look into the var/log/debug.log and confirm the method execution sequence.

Add ProductPlugin.php file in app/code/Magemonkeys/HelloWorld/Plugin/ and copy the following code in it:

<?php
 
namespace MagemonkeysHelloWorldPlugin;
 
class ProductPlugin
{    
    public function beforeGetProduct(MagentoCatalogBlockProductView $subject)
    {
        // logging to test override    
        $logger = MagentoFrameworkAppObjectManager::getInstance()->get('PsrLogLoggerInterface');
        $logger->debug(__METHOD__ . ' - ' . __LINE__);        
    }
    
    public function afterGetProduct(MagentoCatalogBlockProductView $subject, $result)
    {
        // logging to test override    
        $logger = MagentoFrameworkAppObjectManager::getInstance()->get('PsrLogLoggerInterface');
        $logger->debug(__METHOD__ . ' - ' . __LINE__);
        
        return $result;
    }
    
    public function aroundGetProduct(MagentoCatalogBlockProductView $subject, Closure $proceed)
    {
        // logging to test override    
        $logger = MagentoFrameworkAppObjectManager::getInstance()->get('PsrLogLoggerInterface');
        $logger->debug(__METHOD__ . ' - ' . __LINE__);
        
        // call the core observed function
        $returnValue = $proceed(); 
        
        // logging to test override        
        $logger->debug(__METHOD__ . ' - ' . __LINE__);
        
        return $returnValue;
    }    
}
?>

I faced a problem after migration from Magento 1,

When I go to the admin product page, I can’t see the product view just reloading the loader.

When I check the log files gives me error like: PHP Fatal error: Method Magento\Ui\TemplateEngine\Xhtml\Result::__toString() must not throw an exception, caught TypeError: Argument 1 passed to Magento\InventorySalesAdminUi\Model\GetSalableQuantityDataBySku::execute() must be of the type string, null given, called in…

After debugging I found the issue that stated SKU should be empty for migration products.

As you know, in Magento, the SKU is a required field when you create a new product. So in migration, it might happened that store product SKU was blanked or not a string due to corrupted data.

To resolve this issue, we need to run below query:

UPDATE catalog_product_entity SET sku='' WHERE sku IS NULL;

Simply, we set SKU as NULL and fix that where any SKU’s are store blank in the database.

If you ever get below error  :
DateTime::__construct(): Failed to parse time string (11/08/2019) at position 0 (2): Unexpected char

Here is the solution

Update this file : /vendor/magento/module-catalog/Controller/Adminhtml/Product/Initialization/Helper.php

Add one line code :

private function convertSpecialFromDateStringToObject($productData)
{
    if (isset($productData['special_from_date']) && $productData['special_from_date'] != '')
    {
        $productData['special_from_date'] = $this->dateFilter->filter($productData['special_from_date']); /* Add this line */
    	$productData['special_from_date'] = new DateTime($productData['special_from_date']);
    }
    ...

Hope my post is helpful. If you are facing problem during this process, then feel free to comment.

In this guide, I am going to show you, how to remove the product of a particular attribute set in Magento 2 programmatically?

First of all, you have to create a file called “deleteProducts.php” on Magento 2 root directory.

And then paste the below code into that file.

<?php
set_time_limit(0);
ini_set('display_errors', 1);
ini_set('memory_limit', -1);
use MagentoFrameworkAppBootstrap;
require __DIR__ . '/app/bootstrap.php';

$bootstraps = Bootstrap::create(BP, $_SERVER);
$objectManager = $bootstraps->getObjectManager();


deleteAllProducts($objectManager);
 
function deleteAllProducts($objectManager) {
 
    $objectManager->get('MagentoFrameworkRegistry')->register('isSecureArea', true);

    $attrSetName = 'Dress'; // Atribute set name
    $attribute_set_factoryCollection = $objectManager->get('MagentoEavModelResourceModelEntityAttributeSetCollectionFactory');

    $attribute_set_collection = $attribute_set_factoryCollection->create();

    $attribute_set_collection
    ->addFieldToFilter('entity_type_id',4)
    ->addFieldToFilter('attribute_set_name',$attrSetName);

    $att_set = current($attribute_set_collection->getData());
    $attribute_set_id = $att_set["attribute_set_id"];

    $productCollection = $objectManager->create('MagentoCatalogModelResourceModelProductCollectionFactory');
    $collection = $productCollection->create()->addAttributeToSelect('*')->addFieldToFilter('attribute_set_id',$attribute_set_id)->load();
    $app_state = $objectManager->get('MagentoFrameworkAppState');
    $app_state->setAreaCode('frontend');

    foreach ($collection as $product){
        try {
            echo 'Deleted '.$product->getName().PHP_EOL;
            $product->delete();
        } catch (Exception $e) {
            echo 'Failed to remove product '.$product->getName() .PHP_EOL;
            echo $e->getMessage() . "n" .PHP_EOL;
        }
    }      
}

And now you can run this file through cronjob and URL.

So the URL will be like this : http://yourdomainname/deleteProducts.php

That’s it.

I hope my post is helpful. If you still need any assistance about that, please comment below.

Define the extension attribute in XML

app/code/Vendor/Module/etc/extension_attributes.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Api/etc/extension_attributes.xsd">
    <extension_attributes for="MagentoCheckoutApiDataShippingInformationInterface">
        <attribute code="address_two" type="string"/>
    </extension_attributes>
</config>

Assigning the value for extension attributes in knockout js 

app/code/Vendor/Module/view/frontend/web/js/shipping-save-processor-default.js

saveShippingInformation: function () {
                var payload;

                payload = {
                    addressInformation: {
                        shipping_address: quote.shippingAddress(),
                        billing_address: quote.billingAddress(),

                        }
                    }
                };

                return storage.post(
                    resourceUrlManager.getUrlForSetShippingInformation(quote),
                    JSON.stringify(payload)
                ).done(
                    function (response) {
                        quote.setTotals(response.totals);
                        paymentService.setPaymentMethods(methodConverter(response.payment_methods));
                    }
                ).fail(
                    function (response) {
                        errorProcessor.process(response);
                    }
                );
            }
