In Magento 2 how to receive request array? $_POST and $_GET too as we did in Magento 1:

Mage::app()->getRequest()->getPost()

If you are trying this from a controller that extends Magento\Framework\App\Action\Action you can get the request with $this->getRequest()->getPost().
If you are in a custom class, you need to inject the request in the constructor.

<?php
namespace Namespace\Module\Something;
class ClassName 
{
    protected $request;
    public function __construct(
       \Magento\Framework\App\RequestInterface $request
        ....//rest of parameters here
    ) {
       $this->request = $request;
       ...//rest of constructor here
    }
    public function getPost()
    {
        return $this->request->getPostValue();//in Magento 2.*
    }
}

    Same way. Just use getParams instead of getPost

  • Thx, it works. I tried in PHPstorm with xDebug and look in window Watches. But I got empty array.

    My class \Magento\Framework\App\Request\Http does not have a method getPost, are you sure about this?

    @JeroenVermeulen-MageHost there was no MEQP2 standard 2.5 years ago when I wrote this.

Hi you can get it easily in models, blocks and controllers by using:

$this->getRequest()->getPost() 

Or add Magento\Framework\App\RequestInterface to the constructor parameters in your own classes:

<?php
namespace MyModuleNameSpace\MyModule\Block
use Magento\Framework\App\RequestInterface;

class MyClass
{
    /**
     * Request instance
     *
     * @var \Magento\Framework\App\RequestInterface
     */
    protected $request;

    /**
     * @param RequestInterface $request
     */
    public function __construct(RequestInterface $request)
    {
        $this->request = $request;
    }

    public function getMyPostParams()
    {
        $postData = $this->request->getPost();
    }
}

  • Did you try the code? Calling $this->getRequest()->getPost(); returns an Zend\Stdlib\Parameters object for me. Even in core, Magento uses plenty calls like this, with a parameter like for example in Magento\Sales\Controller\Adminhtml\Order\AddComment there is on line 31 a call: $data = $this->getRequest()->getPost('history');

This should work, just test it. Compare and see what is missing.

<?php
namespace MyModuleNameSpace\MyModule\Block
use Magento\Framework\App\RequestInterface;

class MyClass extends \Magento\Framework\View\Element\Template
{
    /**
     * Request instance
     *
     * @var \Magento\Framework\App\RequestInterface
     */
    protected $request;

    /**
     * @param RequestInterface $request
     */
    public function __construct(
        RequestInterface $request,
        \Magento\Framework\View\Element\Template\Context $context,
        array $data = [])
    {
        $this->request = $request;
        parent::__construct($context, $data);
    }

    public function getMyPostParams()
    {
        $postData = $this->request->getPost();
    }
}

    In the template, we don't need to re-declare the request variable. We have already : $this->_request Nov 9, 2017 at 4:21

private $params = ['id', 'name'];

public function execute()
{
    $this->getPostParams();
}

private function getPostParams()
{
    foreach ($this->params as $k) 
    {
        $this->params[$k] = $this->getRequest->getParam($k);
    }
}

namespace Vendor\Module\Controller\Adminhtml\ControllerName;

use Magento\Backend\App\Action;

use Magento\Backend\App\Action\Context;

use Magento\Framework\View\Result\PageFactory;

class ActionName extends Action

{

public function __construct(

    Action\Context $context,

) {

    parent::__construct($context);
}

public function execute()

{

    $data = $this->getRequest()->getPostValue();
