CodePudding user response：

You've got 2 main problems with this code:

User::find($user)->update(['n_photo' => $photo_name]);

First of all, the correct syntax would be to use $user->id, not $user:

User::find($user->id)->update(['n_photo' => $photo_name]);

Second, that is super redundant; $user is already the result of User::find(), so you're doubling up for no reason.

To fix your issue, simply adjust your code to:

$user->update(['n_photo' => $photo_name]);

CodePudding user response：

Just spacing issue please check these two lines

//Before // Wrong

$photo_upload = $request ->n_photo;

$photo_extension = $photo_upload -> getClientOriginalExtension();

//After //Correct

$photo_upload = $request->n_photo;

$photo_extension = $photo_upload->getClientOriginalExtension();
