MurKit commented 7 years ago

I'm on Magento CE 2.1.7.

After I download this extension and copy it to my Magento installation I run some cli commands.

sudo rm -rf var/di/ sudo rm -rf var/cache/ sudo rm -rf var/generation/ sudo rm -rf var/page_cache/

sudo chmod -R 777 pub/ sudo chmod -R 777 var/

php -f bin/magento cache:clean php bin/magento setup:upgrade php bin/magento setup:di:compile

And on the last step there are errors:

use below code :+1: public function __construct( \Mageplaza\HelloWorld\Model\Upload $uploadModel, \Mageplaza\HelloWorld\Model\Post\File $fileModel, \Mageplaza\HelloWorld\Model\Post\Image $imageModel, //\Magento\Backend\Model\Session $backendSession, \Mageplaza\HelloWorld\Model\PostFactory $postFactory, \Magento\Framework\Registry $registry, //\Magento\MediaStorage\Model\File\UploaderFactory $uploaderFactory, /// \Magento\Backend\Model\View\Result\RedirectFactory $redirectFactory , \Magento\Backend\App\Action\Context $context //Phpexcel_PHPExcel $xlsx //\PHPExcel\IOFactory $iOFactory; //Phpexcel_PHPExcel $xlsx

)
{
    $this->_uploadModel    = $uploadModel;
    $this->_fileModel      = $fileModel;
    $this->_imageModel     = $imageModel;
  //  $this->_backendSession = $backendSession;
    $this->redirectFactory =  $context->getRedirectFactory();
    //$this->_iOFactory = $iOFactory;
    //$this->excelFactory = $excelFactory;
    //$this->excelFactory = $excelFactory;
    parent::__construct($postFactory, $registry,$context);
}
