Laravel catch Eloquent “Unique” field error

Question

I am trying to identify when inserting a record using eloquent in Laravel when it throws an exception because of a unique field error.

The code I have so far is:

Answer 1

add this code inside class Handler (exception)

if($e instanceof QueryException){
        $errorCode = $e->errorInfo[1];          
        switch ($errorCode) {
            case 1062://code dublicate entry 
                return response([
                    'errors'=>'Duplicate Entry'
                ],Response::HTTP_NOT_FOUND);    
                break;
            case 1364:// you can handel any auther error
                return response([
                    'errors'=>$e->getMessage()
                ],Response::HTTP_NOT_FOUND);                        
                break;      
        }
     }
    ...
    return parent::render($request, $exception);

I'm assuming you use MySQL, it's probably different for other systems

Okay first, the error code for duplicate entry is 1062. And here's how you retrieve the error code from the exception:

catch (Illuminate\Database\QueryException $e){
    $errorCode = $e->errorInfo[1];
    if($errorCode == 1062){
        // houston, we have a duplicate entry problem
    }
}
