I know there is a simple way to upload image in Symfony 6. In short – create form via form builder and then in the controller we just simply do:

$form = $this->createForm(MyClassType::class);

After form is submitted and valid we can get the image and (if we want to) move it:

if ($image = $form['img']->getData()) {
    $fileName = uniqid().'.'.$image->guessExtension();
    $image->move($imageDir, $fileName);
}

But in my app I can’t do that. I’ve made plain form in html with input type=file. And I don’t know how to access/move uploaded image that way. I can get only name of the file, not actuall image.

In my controller I created new object (which is in my model):

$uploadedData = new MyData();
$allData = $uploadedData->getMyData();

Where in method ‘getMyData()’ I’m checking which inputs (image is not required) have been filled:

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (isset($_FILES['fileName'])) {
              $image = $_FILES['fileName'];
    } else $image = "";
}

and return outcome (submitted data) as an array.

if I check result in the controller via dd($allData); I get (only showing image info):

"image" => array:6 [▼
    "name" => "test.jpg"
    "full_path" => "test.jpg"
    "type" => "image/jpeg"
    "tmp_name" => "C:xampptmpphp89C0.tmp"
    "error" => 0
    "size" => 3909421
  ]

So it seems like all went ok, right?
But I can’t access this image (or move it to the folder where it should be).
I tried access this image doing this ($imageDir is just a path to the desired folder):

if ($image = $allData['image']['name']) {
    $fileName = uniqid().'.'.$image->guessExtension();
    $image->move($imageDir, $fileName);
} else $fileName = null;

I got error: Call to a member function guessExtension() on string. I tried all of the keys. I got error every time. Even tried that:
$image = $allData['image']['name']->getData()
Got error: Call to a member function getData() on string. Other combinations also failed.

In other words – seems like image was uploaded (if that’s the case I wonder where it is…) but I can’t access or move it. Method ‘getData()’ seems working only when we create form via
‘$form = $this->createForm(MyClassType::class);’. But as I stated before – I can’t create form that way here. If someone was wondering – my html form has needed attributes (method=”POST” enctype=”multipart/form-data”).

Any ideas?
