How to get POST and GET requests in Magento 2

September 7, 2015 - Magento 2

In a case of a controller that extends Magento\Framework\App\Action\Action, it is possible to get the request with the aid of $this->getRequest()->getPost().

For a custom class, inject the request in the constructor:

<?php namespace Namespace\Module\Something; class ClassName { protected $request; public function __construct( \Magento\Framework\App\Request\Http $request, ....//rest of parameters here ) { $this->request = $request; ...//rest of constructor here } public function getPost() { return $this->request->getPost(); } }

<?php namespace Namespace\Module\Something; class ClassName { protected $request; public function __construct( \Magento\Framework\App\Request\Http $request, ....//rest of parameters here ) { $this->request = $request; ...//rest of constructor here } public function getPost() { return $this->request->getPost(); } }

How to defer JavaScript execution in Magento 2

September 7, 2015 - Magento 2

Being a boolean attribute, defer specifies that the script is executed after the page parsing. The attribute is aimed at external scripts only (the src attribute should be present). Find more information about defer here.

Despite Magento 2 supports standard script deferring, it never uses defer in its core. To change the situation, you can use the following code:

<?xml version='1.0'?>
<page 
    xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
    layout='admin-login' xsi:noNamespaceSchemaLocation='../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/page_configuration.xsd'>
    <head>
        <script src='Dfe_Login::main.js' defer='defer'/>
    </head>
</page>

<?xml version='1.0'?>

<page

xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'

layout='admin-login' xsi:noNamespaceSchemaLocation='../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/page_configuration.xsd'>

<head>

</head>

</page>

How to programmatically create a configurable Magento 2 product

September 7, 2015 - Magento 2

If the simple and configurable products are not assigned together like in the folowing example, there is a reliable solution.

//simple product
    $simple_product = $this->_objectManager->create('\Magento\Catalog\Model\Product');
    $simple_product->setSku('test-simple');
    $simple_product->setName('test name simple');
    $simple_product->setAttributeSetId(4);
    $simple_product->setSize_general(193); // value id of S size
    $simple_product->setStatus(1);
    $simple_product->setTypeId('simple');
    $simple_product->setPrice(10);
    $simple_product->setWebsiteIds(array(1));
    $simple_product->setCategoryIds(array(31));
    $simple_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' => 100 //qty
        )
    );

    $simple_product->save();

    $simple_product_id = $simple_product->getId();
    echo "simple product id: ".$simple_product_id."\n";

    //configurable product
    $configurable_product = $this->_objectManager->create('\Magento\Catalog\Model\Product');
    $configurable_product->setSku('test-configurable');
    $configurable_product->setName('test name configurable');
    $configurable_product->setAttributeSetId(4);
    $configurable_product->setStatus(1);
    $configurable_product->setTypeId('configurable');
    $configurable_product->setPrice(11);
    $configurable_product->setWebsiteIds(array(1));
    $configurable_product->setCategoryIds(array(31));
    $configurable_product->setStockData(array(
        'use_config_manage_stock' => 0, //'Use config settings' checkbox
        'manage_stock' => 1, //manage stock
        'is_in_stock' => 1, //Stock Availability
        )
    );

    $configurable_product->getTypeInstance()->setUsedProductAttributeIds(array(152),$configurable_product); //attribute ID of attribute 'size_general' in my store
    $configurableAttributesData = $configurable_product->getTypeInstance()->getConfigurableAttributesAsArray($configurable_product);

    $configurable_product->setCanSaveConfigurableAttributes(true);
    $configurable_product->setConfigurableAttributesData($configurableAttributesData);

    $configurableProductsData = array();
    $configurableProductsData[$simple_product_id] = array( //[$simple_product_id] = id of a simple product associated with this configurable
        '0' => array(
            'label' => 'S', //attribute label
            'attribute_id' => '152', //attribute ID of attribute 'size_general' in my store
            'value_index' => '193', //value of 'S' index of the attribute 'size_general'
            'is_percent'    => 0,
            'pricing_value' => '10',
        )
    );
    $configurable_product->setConfigurableProductsData($configurableProductsData);

    $configurable_product->save();

    echo "configurable product id: ".$configurable_product->getId()."\n";

//simple product

$simple_product = $this->_objectManager->create('\Magento\Catalog\Model\Product');

$simple_product->setSku('test-simple');

$simple_product->setName('test name simple');

$simple_product->setAttributeSetId(4);

$simple_product->setSize_general(193); // value id of S size

$simple_product->setStatus(1);

$simple_product->setTypeId('simple');

$simple_product->setPrice(10);

$simple_product->setWebsiteIds(array(1));

$simple_product->setCategoryIds(array(31));

$simple_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' => 100 //qty

)

);

$simple_product->save();

$simple_product_id = $simple_product->getId();

echo "simple product id: ".$simple_product_id."\n";

//configurable product

$configurable_product = $this->_objectManager->create('\Magento\Catalog\Model\Product');

$configurable_product->setSku('test-configurable');

$configurable_product->setName('test name configurable');

$configurable_product->setAttributeSetId(4);

$configurable_product->setStatus(1);

$configurable_product->setTypeId('configurable');

$configurable_product->setPrice(11);

$configurable_product->setWebsiteIds(array(1));

$configurable_product->setCategoryIds(array(31));

$configurable_product->setStockData(array(

'use_config_manage_stock' => 0, //'Use config settings' checkbox

'manage_stock' => 1, //manage stock

'is_in_stock' => 1, //Stock Availability

)

);

$configurable_product->getTypeInstance()->setUsedProductAttributeIds(array(152),$configurable_product); //attribute ID of attribute 'size_general' in my store

$configurableAttributesData = $configurable_product->getTypeInstance()->getConfigurableAttributesAsArray($configurable_product);

$configurable_product->setCanSaveConfigurableAttributes(true);

$configurable_product->setConfigurableAttributesData($configurableAttributesData);

$configurableProductsData = array();

$configurableProductsData[$simple_product_id] = array( //[$simple_product_id] = id of a simple product associated with this configurable

'0' => array(

'label' => 'S', //attribute label

'attribute_id' => '152', //attribute ID of attribute 'size_general' in my store

'value_index' => '193', //value of 'S' index of the attribute 'size_general'

'is_percent' => 0,

'pricing_value' => '10',

)

);

$configurable_product->setConfigurableProductsData($configurableProductsData);

$configurable_product->save();

echo "configurable product id: ".$configurable_product->getId()."\n";

You can review on API functional test aimed at creating configurable product. You code should have the following look:

$product = $productFactory->create(['name'=> 'configurable product', ... ]);
$configurableOption = $optionFactory->create([]);
$linkedProduct = $linkFactory->create([]);
$product->getExtensionAttributes()->setConfigurableProductOptions($configurableOption)l
$product->getExtensionAttributes()->setConfigurableProductLinks($linkedProduct);
$productRepository->save($product)

$product = $productFactory->create(['name'=> 'configurable product', ... ]);

$configurableOption = $optionFactory->create([]);

$linkedProduct = $linkFactory->create([]);

$product->getExtensionAttributes()->setConfigurableProductOptions($configurableOption)l

$product->getExtensionAttributes()->setConfigurableProductLinks($linkedProduct);

$productRepository->save($product)

It is also necessary to mention that the API does not generate simple product, so there is the need to create in advance.
