How to Persist URL parameters when CakePHP form validation fails
- by am2605
Hi,
I'm new to cakephp and trying to write a simple app with it, however I'm stuck with some form validation issues.
I have a model named "Person" which hasMany "PersonSkill" objects. To add a "PersonSkill" to a person, I have set it up to call a url like this:
http://localhost/myapp/person_skills/add/person_id:3
I have been passing through the person_id because I want to display the name of the person we are adding the skills for.
My issue is if the validation fails, the person_id parameter is not persisted to the next request, so the person's name is not displayed.
The add method on the controller looks like this:
function add() {
if (!empty($this->data)) {
if ($this->PersonSkill->save($this->data)) {
$this->Session->setFlash('Your person has been saved.');
$this->redirect(array('action' => 'view', 'id' => $this->PersonSkill->id));
}
} else {
$this->Person->id = $this->params['named']['person_id'];
$this->set('person', $this->Person->read());
}
}
In my person_skill add.ctp I set a hidden field which holds the person_id, eg:
echo $form->input('person_id', array('type'=>'hidden','value'=>$person['Person']['id']));
Is there a way to persist the person_id url parameter when form validation fails, or is there a better way to do this that I'm missing completely?
Any advice would be greatly appreciated.
