File isn't deleted when code is in a specific order - ajax

Question

I ran into the problem that when I try to delete a record from database using ->delete() and my code stopped after successfully deleted the record.
This code doesn't execute the Storage::delete($image)
public function productImageDelete(Request $request){
if($request->ajax()):
$image_id = Input::get('image-id');
$image = Input::get('image');
try {
$image = Image::findOrFail($image_id);
$image->delete();
Storage::delete($image); //This doesn't execute at all
return "success";
} catch ( \Illuminate\Database\QueryException $e) {
return $e;
}
endif;
}
However when I placed Storage::delete($image) before $image->delete(); the code works.
public function productImageDelete(Request $request){
if($request->ajax()):
$image_id = Input::get('image-id');
$image = Input::get('image');
try {
Storage::delete($image); //This executes first
$image = Image::findOrFail($image_id);
$image->delete();
return "success";
} catch ( \Illuminate\Database\QueryException $e) {
return $e;
}
endif;
}

You need to take a look at the details. You're creating two variables named $image and that's your issue.
On the first case, you're calling Storage::delete($image); where $image is an object and on the second case, you're calling the same method but in that case $image is a Input::get('image').
If you simply rename the variable of Input::get('image') to, say $imageParam = Input::get('image') and execute Storage::delete($imageParam);, it should work on both cases.
The bottomline is: never use the same variable name, as it will led to such unnecessary confusions.
