Have run into a few problems recently with various aspects of CakePHP – the main one is CakePHP writing random rows to a table when calling the save() method for a model.
For example:
function addfriend($user_id, $friend_id) { $this->data['Friend']['user_id'] = $user_id; $this->data['Friend']['friend_id'] = $friend_id; $this->data['Friend']['accepted'] = 0; $this->data['Friend']['rejected'] = 0; $this->User->Friend->Create(); if($this->User->Friend->save($this->data)){ echo ("Friend Added"); } else { echo ("Error Adding Friend"); } }
Will cause several rows to be written to the database when only one is required. This is because there is no redirect / exit statement so the script is trying to return to the same page and method several times.
However this code will work correctly:
function addfriend($user_id, $friend_id) { $this->data['Friend']['user_id'] = $user_id; $this->data['Friend']['friend_id'] = $friend_id; $this->data['Friend']['accepted'] = 0; $this->data['Friend']['rejected'] = 0; $this->User->Friend->Create(); if($this->User->Friend->save($this->data)){ $this->Session->setFlash('Friend Added'); $this->redirect('users/view/'.$user_id); exit; } else { $this->Session->setFlash('Error Adding Friend'); exit; } }
