recommend controller

<?php namespace app\controller; use cake\orm\tableregistry; use app\controller\appcontroller; use cake\mailer\email;  use cake\orm\table; use app\model\tabel\recommendtabel;  use cake\event\event; class recommendcontroller extends appcontroller  {  public function index()     {          $temp = $this->recommend->newentity();         if ($this->request->is('post')) {             $temp = $this->recommend->patchentity($temp, $this->request->data);             if($temp) {                 $name=$this->request->data('name');         $receiver_email=$this->request->data('emai');          $subject_title='temp';         $sender_email=$this->request->data('yemail');          $email = new email();         $email->template('invite', 'default')             ->viewvars(['value' => $name])             ->emailformat('html')             ->from($sender_email)             ->to($receiver_email)             ->subject($subject_title)             ->send();                 $this->flash->success(__('the user has been saved.'));                 return $this->redirect(['action' => 'add']);             } else {                 $this->flash->error(__('the user not saved. please, try again.'));             }         }         $this->set(compact('temp'));         $this->set('_serialize', ['temp']);      } 

the patchentity function returns patched entity. so, result of line evaluate true when used in boolean context.

$temp = $this->recommend->patchentity($temp, $this->request->data); 

so, check whether errors detected, if statement cannot compare returned value true, instead this:

if (!$temp->errors()) {
