Tables Only Update When All Fields Have Been Changed - laravel

Question

If I change just the user table items it'll update them (if i change everything in the user table rows). However, it'll only update the user_infos table when I edit everything.
ProfilesController.php
public function update(Request $request)
{
$user_id = Auth()->user()->id;
$id = Auth()->user()->id;
$this->validate($request, array(
'first_name' => 'required|string|max:255',
'last_name' => 'required|string|max:255',
'email' => 'required|string|email|max:255|unique:users',
'type' => 'required|string',
'description' => 'string',
'projects' => 'string',
'experience' => 'string',
'links' => 'string',
'status' => 'string'
));
if($request->hasFile('avatar')){
$avatar = $request->file('avatar');
$filename = time() . '.' . $avatar->getClientOriginalExtension();
Image::make($avatar)->resize(300, 260)->save( public_path('/images/uploads/avatars/' . $filename ) );
$user = Auth::user();
$user->avatar = $filename;
$user->save();
}
$user = User::find($id);
$user->first_name = $request->input('first_name');
$user->last_name = $request->input('last_name');
$user->email = $request->input('email');
$user->type = $request->input('type');
$user_info = User_Info::find($user_id);
//$user_info = User_Info::where('user_id', $user->id)->first();
$user_info->description = $request->input('description');
$user_info->projects = $request->input('projects');
$user_info->experience = $request->input('experience');
$user_info->links = $request->input('links');
$user_info->status = $request->input('status');
$user->save();
$user_info->save();
return redirect()->route('profile')->withUser($user);
}

Answer 1

In here:
$user->update(); // <--- try this
$user->save();
$user_info->save();

Answer 2

In my ProfilesController.php I had to change the validation for "email" inside public function update(Request $request) a little bit.
From:
$this->validate($request, array(
'first_name' => 'required|string|max:255',
'last_name' => 'required|string|max:255',
'email' => 'required|string|email|max:255|unique:users',
'type' => 'required|string',
'description' => 'string',
'projects' => 'string',
'experience' => 'string',
'links' => 'string',
'status' => 'string',
));
To:
$this->validate($request, array(
'first_name' => 'required|string|max:255',
'last_name' => 'required|string|max:255',
'email' => 'required|string|email|max:255|unique:users,email,'.$id,
'type' => 'required|string',
'description' => 'string',
'projects' => 'string',
'experience' => 'string',
'links' => 'string',
'status' => 'string',
));
