validation set in model :-

> $validator-\>notEmptyFile(‘featureImage’, \_\_(‘please set feature image!’))  
> -\>add(‘featureImage’, ‘file’, [

Form must be

```

not `type => file`

it does not matter @shadowx.jb because [‘type’=\>‘file’] also generator same ectype attribute in html:-

Cakephp also mention that kind of code in Official Docs :-

Ok, sorry… try

is `featureImage` set as `accessible` inside your Article entity class?

Your code mostly says `featureImage`, but your entity dump has a field in it called `feature_image`.

</div>

The `featureImage` object does not have to be defined in the entity class. I tried the same example and it works for me. Here is the result of `$this->request->getData()`

```auto
[
  'language_id' => '2',
  'user_id' => '8',
  'date' => '2024-02-16',
  'title' => 'hhh',
  'content' => '<p>hh</p>',
  'url' => '',
  'featureImage' => object(Laminas\Diactoros\UploadedFile) id:0 {
    private error => (int) 0
    private file => 'C:\wamp\tmp\php776A.tmp'
    private moved => false
    private stream => object(Laminas\Diactoros\Stream) id:1 {
      protected resource => (resource) Resource id #22
      protected stream => 'C:\wamp\tmp\php776A.tmp'
    }
    private size => (int) 112216
    private clientFilename => 'image-02.jpg'
    private clientMediaType => 'image/jpeg'
  },

You’ve shown the form and the validator config but how do you patch the request data into the entity so that the validator is being called.

</div>

I’m still coming back to the fact that the most recent entity dump that you’ve shown us has a field called `feature_image` (along with `article_title`, `article_content`, etc.), but the error is on `featureImage`. Where is `feature_image` coming from, and why does the entity not have a field in it called `featureImage`?

even if I allow PNG mimetype but it still throw error… you can see in error index.  
it also throw error when i upload other mimetype image like GIF… obviously throw error because i just allow only PNG JPEG JPG there in validation

Can you please insert the code as a code and not an image?  
Please try to remove this from the entity `featureImage => true`  
And please insert the entire all form code here - not the image.  
I want `$this->request->getData()` to see this right below the POST method.
