Magento 2 use registry

Today we talk about how in Magento 2 use registry. This tutorial includes register, registry, get registry value and unregister registry value. Registry is not a replacement of session in magento 2. Registry stores the value till the page loads. After the page loading the registry is unregister automatically. Registry can be helpful in many ways like you wish to register products Ids on one page from products collections and fetch them on another page , it’s so handy to work around registries. Following example will give you an insight to the actual implementation .So let’s start with our example registry example.

Registry Object

First we inject the registry class instance. So we can use registry in our class.

public function __construct(
   
    \Magento\Framework\Registry $registry,
   
) {
   
    $this->registry     = $registry;
   
}

Register Registry Object

Now we use registry instance to register the registry object.

public function registerValue()
{
 return $this->registry->register('test_var' , 'sometext');
}

get Registry Object

Now we use registry instance to get registry object.

public function getValue()
{
 return $this->registry->registry('test_var');
}

Unregister Registry Object

Now we use registry instance to unregister the registry object.

public function unSetValue()
{
   return $this->registry->unregister('test_var');
}

Magento 2 display discount percent product page

Today we discuss how in Magento 2 display discount percent product page. This topic will cover how to show % percentage saving on current product. You can use this code on any product product listing or product widget page. You can also use this code product detail page. So let’s start with our example. You need to get $_product->getFinalPrice() and $_product->getPrice() to calculate the percentage of current product.

$_finalPrice = $_product->getFinalPrice();
$_price = $_product->getPrice();
if($_finalPrice < $_price):
   $_savingPercent = 100 - round(($_finalPrice / $_price)*100);
      echo $_savingPercent; ?> % Off
<?php endif; ?>

Magento 2 create product programmatically

Today we discussed how in Magento 2 create product programmatically. This tutorial includes the process of creating a simple product, set image to product and set quantity to product. So lets start with creating a simple product. We can do this in two ways- one is creating product with factory method and other is creating product with object manager.

Create Product with Factory Method

  protected $_product;  


  public function __construct(
     
        \Magento\Catalog\Model\ProductFactory $_product

    ) {


        $this->_productloader = $_productloader;
     
    }
    public function createProduct()
    {
       
        $_product = $this->_productloader->create();
        $_product->setName('First Test Product');
        $_product->setTypeId('simple');
        $_product->setAttributeSetId(4);
        $_product->setSku('test-SKU');
        $_product->setWebsiteIds(array(1));
        $_product->setVisibility(4);
        $_product->setPrice(400);
        $_product->setImage('/simpeproduct/test.jpg');
        $_product->setSmallImage('/simpeproduct/test.jpg');
        $_product->setThumbnail('/simpeproduct/test.jpg');
        $_product->setStockData(array(
            'use_config_manage_stock' => 0, //'Use config settings' checkbox
            'manage_stock' => 1, //manage stock
            'min_sale_qty' => 1, //Minimum Qty Allowed in Shopping Cart
            'max_sale_qty' => 2, //Maximum Qty Allowed in Shopping Cart
            'is_in_stock' => 1, //Stock Availability
            'qty' => 1000 //qty
            )
        );

        $_product->save();
        echo $_product->getId();
    }

Update Product with factory method

  protected $_product;  


  public function __construct(
     
        \Magento\Catalog\Model\ProductFactory $_product

    ) {


        $this->_productloader = $_productloader;
     
    }
    public function updateProduct()
    {
       
        $_product = $this->_productloader->create()->load(2047);
        $_product->setName('First Test Product Updated');
        $_product->save();
    }

Create Product with Object manager

 <?php
    $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
    $_product = $objectManager->create('Magento\Catalog\Model\Product');
    $_product->setName('First Test Product');
    $_product->setTypeId('simple');
    $_product->setAttributeSetId(4);
    $_product->setSku('test-SKU');
    $_product->setWebsiteIds(array(1));
    $_product->setVisibility(4);
    $_product->setPrice(400);
    $_product->setImage('/simpeproduct/test.jpg');
    $_product->setSmallImage('/simpeproduct/test.jpg');
    $_product->setThumbnail('/simpeproduct/test.jpg');
    $_product->setStockData(array(
            'use_config_manage_stock' => 0, //'Use config settings' checkbox
            'manage_stock' => 1, //manage stock
            'min_sale_qty' => 1, //Minimum Qty Allowed in Shopping Cart
            'max_sale_qty' => 2, //Maximum Qty Allowed in Shopping Cart
            'is_in_stock' => 1, //Stock Availability
            'qty' => 1000 //qty
            )
        );

$_product->save();
echo $_product->getId();

Update Product with Object manager

Now our custom product is created. Now we will update product. So doing with following example just.

            $_product = $objectManager->create('Magento\Catalog\Model\Product')->load(2047);
    $_product->setName('First Test Product Updated');
    $_product->save(); ?>

Magento 2 use custom query

Today we will discuss how in Magento 2 custom query works. Sometime magento 2 model is not enough to get data from database as per our requirements. So to fulfill this requirement we use custom query. In this example we will use select custom query, custom delete query, custom insert query and custom update query. So let’s start with example.

Get connection

First of all we will establish a connection to execute the query.

 $this->_resources = \Magento\Framework\App\ObjectManager::getInstance()->get('Magento\Framework\App\ResourceConnection');          
        $connection= $this->_resources->getConnection();

Insert Query

It is simple to use insert query just set the values for columns. Use the inset method.

$array=array(‘column1’=>'column1','column2'=>'column2');

$connection->insert($this->_resources->getTableName(test_table), $array);

Select Query

Selecting table data in custom query you can use following code.

$select = $connection->select()->from(['o' =>  $this->_resources->getTableName(test_table)]);
$result = $connection->fetchAll($select);

       foreach ($result as $data) {
           echo $data['id'];
            }

Update Query

Updating table data in custom query you can use following code.

$id = 1;
 $sql = "Update " . $this->_resources->getTableName('test_table') . " Set `title` ='test title' where `id` = ".$id;
     $connection->query($sql);

Delete Query

To delete table data in custom query you can use following code.

$id = 1;
$condition = $this->getConnection()->quoteInto('id = ?', $id);
            $this->getConnection()->delete($this->getTable('test_table'), $condition);

Join Table

To join table in custom query you can use following code.

        $select = $connection->select()->from(['o' =>  $this->_resources->getTableName('test_table')])->joinleft(
        ['test_table1' => $this->_resources->getTableName('test_table1')],
        'o.id = test_table1.id',
        ['column1','column2']
    );

Magento 2 Render WYSIWYG content

Today we discuss how in Magento 2 Render WYSIWYG content. This topic will cover how to render wysiwyg editor content.There are two ways to render the WYSIWYG content. First Zend_Filter_Interface and second Using the \Magento\Cms\Model\Template\FilterProvider.

Using Zend Interface

namespace QaisarSatti\HelloWorld\Block;

class HelloWorld extends \Magento\Framework\View\Element\Template
{
protected $contentProcessor;
public function __construct(
    \Zend_Filter_Interface $templateProcessor,
) {
 
    $this->contentProcessor = $contentProcessor;
}
public function processContent($content)
{
    return $this->contentProcessor->filter($content);
}
}

Now Add block reference in di.xml

<type name="QaisarSatti\HelloWorld\Block\HelloWorld">
    <arguments>
        <argument name="contentProcessor" xsi:type="object">Magento\Widget\Model\Template\Filter</argument>
    </arguments>
</type>

Now call method from phtml

<?php echo $block->processContent($content);?>

Using CMS Model

namespace QaisarSatti\HelloWorld\Block;

class HelloWorld extends \Magento\Framework\View\Element\Template
{
protected $contentProcessor;
public function __construct(
    \Magento\Cms\Model\Template\FilterProvider $contentProcessor,
) {
 
    $this->contentProcessor = $contentProcessor;
}
public function processContent($content)
{
    return $this->contentProcessor->getPageFilter()->filter($content);
}
}

Now call method from phtml

<?php echo $block->processContent($content);?>
