Laravel 5.2 File Upload always (/tmp) saved in DB - laravel

Question

I Have my code below, it successfully move the file in the desired path. My problem is that in db it always saved like (/tmp/phpI9zJ1F) with random characters after tmp/. How do I solve this problem?
$quiz = Quiz::findOrFail($id);
$tmp = '';
if( $request->hasFile('survey_image') )
{
$extension = $request->file('survey_image')->getClientOriginalExtension();
do{
$rand = rand(11111,99999);
$imageName = $rand.'.'.$extension;
$tmp = $imageName;
$is_duplicate = Quiz::where('survey_image', $imageName)->count();
}
while( $is_duplicate!=0 );
$request['survey_image'] = (string)$tmp;
$quiz->survey_image_path = 'images/surveys/';
}
$request->file('survey_image')->move(
'images/surveys/' , $tmp);
$quiz->update($request->all());

Answer 1

You would need to use replace() or merge() in order to override the value in $request.
$request->replace(array('survey_image' => (string)$tmp));

Answer 2

You hadn't explained much about it, but I believe that this is a method to only update a image.
So, I would do something like that:
$quiz = Quiz::findOrFail($id);
$tmp = '';
if( $request->hasFile('survey_image') )
{
$extension = $request->file('survey_image')->getClientOriginalExtension();
do{
$rand = rand(11111,99999);
$imageName = $rand.'.'.$extension;
$tmp = $imageName;
$is_duplicate = Quiz::where('survey_image', $imageName)->count();
}
while( $is_duplicate!=0 );
$request['survey_image'] = (string)$tmp;
$quiz->survey_image_path = 'images/surveys/';
$request->file('survey_image')->move(
$quiz->survey_image_path , $tmp);
$quiz->update([
'survey_image' => '/'.$quiz->survey_image_path.$imageName,
]);
}
If you want to reuse your code, you can do something like: (Ps. Code not tested!)
/**
* Handle File Upload
* #param UploadedFile $file [File from request]
* #param string $path [Path where to save the file]
* #param string|boolean $current_file [An old file that you want to delete, before save the new one]
* #return string
*/
public function updateImage(UploadedFile $file, $path, $current_file = false)
{
//Set a random name to the file
$extension = $file->getClientOriginalExtension();
$fileName = str_random(32) . '.' . $extension;
//Delete an old file first
if ($current_file !== false)
if (File::exists($current_file))
File::delete($current_file);
//Move new file to the directory
$file->move($path, $fileName);
return '/'.$path.$imageName;
}
And where you want to save on database:
if( !$request->hasFile('survey_image') ) return false; //Or what you want
$quiz = Quiz::findOrFail($id);
$quiz->update([
'survey_image' => $this->updateImage(request('survey_image'), 'images/surveys/');
]);
