Hi, if I am trying to upload many pictures at the same time i am getting an error that says: ‘Object of class Laminas\Diactoros\UploadedFile could not be converted to string’

StartsController.php:

```
    if ($this->request->is('post')) {
        $start->steps[] = $start;
        $start->setDirty('steps', true);
        
        $image2 = $this->request->getData();
        debug($image2);
        
        $recipe = $this->Start->patchEntity($start, $this->request->getData(), ['associated' => 
       ['Steps']]);

```

add.php (view):

echo $this-\>Form-\>control(‘steps.0.image’,[‘type’=\>‘file’]);

StepsTable.php:

```
        $validator
        ->allowEmptyFile('image')
        ->add( 'image', [
            'mimeType' => [
                'rule' => ['mimeType', [ 'image/jpg', 'image/png', 'image/jpeg'] ],
                'message' => 'Please upload only jpg and png.',
            ],
            'fileSize' => [
                'rule' => ['fileSize', '<=', '1MB'],
                'message' => 'Image file size must be less than 1MB.',
            ],
        ] );

```

* * *

The debug($image2) throws:

APP/Controller/StartsController.php (line 642)  
[  
‘title’ =\> ‘test’,  
‘steps’ =\> [  
(int) 0 =\> [  
‘body’ =\> ‘test’,  
‘image’ =\> object(Laminas\Diactoros\UploadedFile) id:0 {  
private clientFilename =\> ‘test.jpg’  
private clientMediaType =\> ‘image/jpeg’  
private error =\> (int) 0  
private file =\> ‘/tmp/phpsxf4LO’  
private moved =\> false  
private size =\> (int) 61717  
private stream =\> null  
},  
],

but the $recipe = $this-\>Start-\>patchEntity($start, $this-\>request-\>getData(), [‘associated’ =\> [‘Steps’]]); throws the error:

# Object of class Laminas\Diactoros\UploadedFile could not be converted to string📋

Any ideas? Thanks..

thanks i found that post before but i didnt look any closer because:

‘width’ =\> [Validation::COMPARE\_GREATER\_OR\_EQUAL, 10],  
‘height’ =\> [Validation::COMPARE\_GREATER\_OR\_EQUAL, 10],

was deprecated … BUT now i see that what he wrotes before was right. The column in the database should not have the same name as what you provide with the form control… I did this before without problems (without hasmany) but in this case it should def. have a different name!

thanks
