php - A four digit year could not be found Data missing save condition -

this start_date field format in interview form "yyyy-mm-dd".

the issue can't save when didn't fill start_date field.

here's savehandler code far :

public function savehandler(request $request, $obj) {     try {         db::begintransaction();         $obj->fill($request->all());         $obj->start_date = isset($interviewtracks['start_date']) ? $interviewtracks['start_date'] : 'yyyy-mm-dd';         if (!$obj->save()) {             throw new validationexception($obj->errors());         }             foreach($request->interviewtracks $interviewtracks) {                 if (empty($interviewtracks['id'])) {                     $interviewtracks = new interviewtrack();                 }                 else {                     $interviewtracks = interviewtrack::find($interviewtracks['id']);                 }                 $interviewtracks->interview()->associate($obj);                 $interviewtracks['interview_id'] = isset($interviewtracks['interview_id']);                 $interviewtracks->status = $interviewtracks['status'];                 $interviewtracks->track_date = isset($interviewtracks['track_date']) ? $interviewtracks['track_date'] : 'yyyy-mm-dd';                 $interviewtracks->outcome = $interviewtracks['outcome'];                 $interviewtracks->remarks = $interviewtracks['remarks'];                 $interviewtracks->save();             };             if (!$interviewtracks->save()) {                 throw new validationexception($interviewtracks->errors());             }          db::commit();         return $this->sendsuccessresponse($request);     } catch (validationexception $e) {         db::rollback();         \log::error($e->errors);         return $this->senderrorresponse($request, $e->errors);     } catch (exception $e) {         db::rollback();         \log::error($e->getmessage());         return $this->senderrorresponse($request,'unable process. please contact system administrator');     }  } 

any idea ?

you should set start_date column nullable() default, if want leave start_date, can leave , eloquent automatically fill null there. use in migrations set nullable...

// example - demo schema::create('users', function (blueprint $table) {     $table->increments('id');     $table->string('name');     $table->date('start_date')->nullable(); // <-------- field sets nullable default     $table->timestamps(); }); 

hope helps!
