Laravel file is not uploded-CodePudding

I try to make a page to upload some files to server side. But it does not work.

// **Here my upload.blade.php**

        var fileRef;
        return (fileRef = file.previewElement) != null ?
        fileRef.parentNode.removeChild(file.previewElement) : void 0;
    },
    success: function (file, response) {
      console.log(response);
    },
  }
</script>

// **my web.php**


Route::get('upload',function(){
    return view('upload');
});
Route::post('upload/classification', [imageClassificationController::class, 'uploadDataset']);

<?php

// my imageClassificationController.php

namespace App\Http\Controllers;
use App\Models\imageClassificationModel;
use Illuminate\Http\Request;
use App\Models\fileTransferModel;
use Auth;
config('projectConfigs.pathConfigs');
class imageClassificationController extends Controller
{
    
    public function uploadDataset()
    {
        try{
        
        $file = request()->file();
        //echo 'File Name: '.$file->getClientOriginalName();
        //return __DIR__;
        //$fileName= $file->getClientOriginalName();
        //return $file;
        

$file->move(__USERFOLDERS__.DIRECTORY_SEPARATOR.Auth::user('foldername').DIRECTORY_SEPARATOR.'image-classification'.DIRECTORY_SEPARATOR.'datasets',$file);
        return $file->getClientOriginalName();
    }
        catch(Exception $e){
            return 'test'.$e;
            
        }
        
    }
    
    

}

These codes return 500 internal server error. But if I return $file, it returns javascript file object. I don't know why I cant save the uploaded file. Also getClientOriginalName returns 500 internal server error. And at last, try-catch also returns 500 internal server error.

Thanks for your helps...

You've got to add the input name to the request file function, and use the Laravel File move functionality:

public function uploadDataset()
{
    try{
    
    $file = request()->file('file'); // the input name attribute
    

    $file->move(__USERFOLDERS__.DIRECTORY_SEPARATOR.Auth::user('foldername').DIRECTORY_SEPARATOR.'image-classification'.DIRECTORY_SEPARATOR.'datasets'.DIRECTORY_SEPARATOR, $file->getClientOriginalName());
    return $file->getClientOriginalName();
    }
    catch(Exception $e){
        return 'test'.$e;
        
    }
    
}
