I worked on a similar problem. I have not made a component (yet) But
this is what I did.
First on the controller I checked if the session data for my invoice
header data was stored.
I am new at cake.
if (!$this->Session->check('documentoventa'))
{
$sucursal = $this->Session->read('Sucursal');
$usuario = $this->Session->read('User');
$Documentoventa['fecha'] =
$this->Session->read('Fecha');
$Documentoventa['numero_documento'] =
$correlativo['Correlativo']['correlativo'];
$Documentoventa['tipodocumentoventa_id'] = 1;
$Documentoventa['bodega_id'] =
$sucursal['Bodega']['0']['id'];
$Documentoventa['cajero_id'] = $usuario['id'];
$this->Session->write('Documentoventa',
$Documentoventa);
}
$this->set('documentoventa',
$this->Session->read('Documentoventa'));
$this->set('data', $this->Session->read('Transaccion'));
$this->render();
Then when I want to save de products I did this.
if (!empty($this->params['data'])){
if (!$this->Session->check('Transaccion')){
$this->Session->write( 'Transaccion\'][\'0' ,
$this->params['data']['Transaccion']);
$this->Session->write('numero_transaccion', 0);
}
$numero_transaccion =
$this->Session->read('numero_transaccion');
$numero_transaccion++;
$this->Session->write(
'Transaccion\'][\''.$numero_transaccion
, $this->params['data']['Transaccion']);
$this->Session->write('numero_transaccion',
$numero_transaccion);
$this->set('data', $this->Session->read('Transaccion'));
}
$this->render('fact_detalle', 'ajax');
Again I am new at cake and most probably you could optimize this code.
I bases my selft loosely on the example in the wiki.
http://wiki.cakephp.org/docs:session.
Hope that helps. Let me know what you did I apreciate it.
