Magento 2 PHP Fatal error: Class not found when compiling

Question

When I compile I get this error:

PHP Fatal error: Class 'Magento\Catalog\Controller\Adminhtml\Category\Image\Upload' not found in /var/www/html/magento/app/code/Plazathemes/Override/Controller/Adminhtml/Category/Image/Upload.php on line 11

EDIT with the code:

enter image description here

Still unable to fix can someone write the soltion to fix this.

• Stijn Duynslaeger - Echron: Are you sure all composer packages are installed? If something is corrupt in your composer and you do composer install/update it won't fix it. You have to force reinstall that package. Try cleaning the vendor folder and run composer install or composer update
• DiLjiT singh: Can you please provide the steps to follow to do this.
• Khoa Truong: Did you remove var/di, var/generation and try run di compile again?
• Kishor Hase: Clear cache and generated files and again recompile. Hope this will help you

Answer 1

Seem that you're trying to override the class Magento\Catalog\Controller\Adminhtml\Category\Image\Upload. So, make sure your custom class will extend from this class.

class Upload extends \Magento\Catalog\Controller\Adminhtml\Category\Image\Upload {
 ......
}

Answer 2

Not sure why you are getting the error itself but if i may suggest just making your file like this?

 namespace ....
 use Magento\Backend\App\Action;
use Magento\Catalog\Model\ImageUploader;
 class Upload extends Action{
 /**
 * Image uploader
 *
 * @var \Magento\Catalog\Model\ImageUploader
 */
 protected $imageUploader;
 /**
 * Upload constructor.
 *
 * @param Action\Context $context
 * @param \Magento\Catalog\Model\ImageUploader $imageUploader
 */
 public function __construct(
 Action\Context $context,
 ImageUploader $imageUploader
 ) {
 parent::__construct($context);
 $this->imageUploader = $imageUploader;
 }
 public function execute(){
 ....
 }
 }

I also suggest you use the Magento image uploader instead of the category uploader unless that is really your intention. Like here Create beautiful image upload in configuration magento 2

• CompactCode: Just a comment. Since i do not know the intend or the page where you are using this i can not provide a specific solution but i hope this helps

Answer 3

Try to give a alias name for the extended class - as shown below:

use Magento\Catalog\Controller\Adminhtml\Category\Image\Upload as CatalogImageUopload
class Upload extends CatalogImageUopload
{
 -----write your code here---
}
