Laravel 5.4 file uploading error - fileName not uploaded due to an unknown error

Question

Im trying to upload multiple images to via below code in laravel. In my form there are 3 types of images to be selected to upload. When user select all the images and then submit the form. I need to upload all the images to same folder . First images get uploaded in to the folder. But then it gives me below error.

The file "1575738164-main-slider2.webp" was not uploaded due to an unknown error.

Controller

  if ($request->hasFile('image') &&  $request->hasFile('image_575') && $request->hasFile('image_768')){

        $file = $request->image;
        $file_575 = $request->image_575;
        $file_768 = $request->image_768;

        $name = time().'-'.$file->getClientOriginalName();
        $name_575 = time().'-'.$file_575->getClientOriginalName();
        $name_768 = time().'-'.$file_768->getClientOriginalName();

        $names = [ $name , $name_575 , $name_768];

        foreach ( $names as $n){

            $file->move('uploads/banners/',$n);   
        }

        $banner = new Banner();
        $banner->name = $name;
        $banner->name_575 = $name_575;
        $banner->name_768 = $name_768;

        $banner -> side_color = $request -> side_color ;
        $banner->type = $request->type;
        $banner->save();
    }

Please note that I have almost gone through below questions. Laravel: The file was not uploaded due to an unknown error

Answer 1

First only using time() method won't work to generate unique file name for all three images all the time and when a concurrent request occurs.

Second:

    $names = [ $name , $name_575 , $name_768];

    foreach ( $names as $n){

        $file->move('uploads/banners/',$n);   
    }

What you are looping is totally wrong. You are trying to move the same image, $file for three times.

You have to move all the three images inside the loop: `

    $file = $request->image;
    $file_575 = $request->image_575;
    $file_768 = $request->image_768;

`

So, you should probably do:

 $filesToMoves = [$name=> $file, $name_575 => $file2 , $name_768 => $file3];

foreach($filesToMoves as $fileName => $fileToMove){
        $fileToMove->move('uploads/banners/',$fileName);  
}
