             ->update(['status' => 'paid',
                       'purshase_time' => $purchase_time
             ]);

 }elseif($value == '700'){

     $user_id = Auth::user()->id;

     $Totalpurchase = DB::table('time_tracker')->where('user_id', $user_id->user_id )->sum('purshase_time');

         $purchase = $Totalpurchase + 25;

         DB::table('users')
             ->where('user_id', $user_id)
             ->update(['status' => 'paid',
                       'purshase_time' => $purchase_time
             ]);


 }elseif($value == '1300'){

     $user_id = Auth::user()->id;

     $Totalpurchase = DB::table('time_tracker')->where('user_id', $user_id->user_id )->sum('purshase_time');

         $purchase = $Totalpurchase + 50;

         DB::table('users')
             ->where('user_id', $user_id)
             ->update(['status' => 'paid',
                       'purshase_time' => $purchase_time
             ]);

 }


 return view('success');    

 }


 public function failed() {

 return view('failed'); 

 }


 }

Answer 1

You tried to access the user_id property from an integer (the $user_id):

$Totalpurchase = DB::table('time_tracker')->where('user_id', $user_id->user_id )->sum('purshase_time');

Just replace the $user_id->user_id part with $user_id. The $user_id is already an id of logged user. So your code should look like this instead:

$Totalpurchase = DB::table('time_tracker')->where('user_id', $user_id)->sum('purshase_time');

I found three occurrences of $user_id->user_id on your PaypalController class. Don't forget to replace all of them.

Hope this help!
