Save datas with multiple relationships with cakephp 1.2 - cakephp

Question

I’ve been stuck for a couple of months on an old cakephp 1.2 I don’t understand the logic of this framework and I am totally lost ....
I have a form to add/remove from my table called contract (see below)
As you can see, I want to be able to add 1 zone per form. I managed to create a table of performances with their own zone here.
array(
'files' => '',
'Contract' => array(
'name' => '',
'beggin' => '',
'end' => '',
'content1' => '<p><br></p>',
'content2' => '<p><br></p>',
'content3' => '',
'content4' => '',
'content5' => '',
'content7' => '',
'content8' => ''
),
'Zone' => array(
(int) 0 => array(
'zone_name' => 'Bat A',
'id_prestation' => array(
(int) 0 => '10',
(int) 1 => '11'
)
),
(int) 1 => array(
'zone_name' => 'Bat B',
'id_prestation' => array(
(int) 0 => '10',
(int) 1 => '12',
(int) 2 => '13',
(int) 3 => '14'
)
)
)
)
so far, I have no difficulties.
the relation between the tables Contract and Prestation is a $hasAndBelongsToMany
here is my form :
My problem is that when the form is submitted, the data are not saved.
Could someone please explain what is it that i’m doing wrong and explain what i should do plz ?
Below is all my codes that you may need to get what i’m trying to explain:
<?php
class Contract extends AppModel {
public $hasMany = array('Document', 'Statu');
public $hasAndBelongsToMany = array('Prestation');
public $belongsTo = array('Client', 'Residence'); public function contracts() {
return $this->find(
'all',
array(
'conditions' => array(
'Contract.is_active' => false
)
)
);
}
}
My function of adding a new contract:
public function add() { if ($this->request->is(array('post', 'put')))
{
// TODO: Rewrite or remove the two next conditions when client and residences will be re-implemented.
// SUPPRESSION DU CLIENT
if (!empty($this->request->data['Contract']['client_id'])) {
unset($this->request->data['Client']);
} else {
unset($this->request->data['Contract']['client_id']);
} // SUPPRESSION DE LA RESIDENCE
if (!empty($this->request->data['Contract']['residence_id'])) {
unset($this->request->data['Residence']);
} else {
unset($this->request->data['Contract']['residence_id']);
} // AJOUT DU STATUS
// AJOUT DES PRESTATIONS
if (!empty($this->request->data['Zone'])) {
foreach ($this->request->data['Zone'] as $key => $zone) {
$this->request->data['Zone'][$key] = $zone;
}
}
$this->request->data['Statu'] = array( 0 => array( 'status' => 'proposed' ) ); // AJOUT DU CONTRAT
$this->Contract->create(); $this->request->data['Contract']['is_active'] = false;
if ($this->Contract->saveAll($this->request->data))
{
$this->Session->setFlash(__('Contrat enregistré.'));
return $this->redirect(array('controller' => 'contracts', 'action' => 'index'));
} $this->Session->setFlash(__("Impossible d'enregistrer le devis."));
}
else
{
$this->set( 'clients', $this->Client->find('list') );
$this->set( 'residences', $this->Residence->find('list') );
$this->set( 'prestations', $this->Prestation->find('list') );
}
}
Thank you for your help
