Creare automaticamente con Symfony un Form per accedere ai dati del dababase.
In Symfony un progetto è composto da applicazioni suddivise in moduli, ad esempio:
– jobeet/apps/frontend/modules/contenuto
– jobeet/apps/frontend/modules/job
– jobeet/apps/frontend/modules/nome altro modulo …
– jobeet/apps/nome altra app…
1. Generiamo automaticamente il codice php per la gestione di un modulo di nome ‘job’
cmd.exe -> C:\wamp64\www\jobeet>symfony doctrine:generate-module –with-show –non-verbose-templates frontend job JobeetJob
verrà creato automaticamente:
apps/frontend/modules/job/actions/
apps/frontend/modules/job/templates/
in particolare apps/frontend/modules/job/actions/action.class.php
<?php
/**
* job actions.
*
* @package symfony
* @subpackage job
* @author Your name here
* @version SVN: $Id: actions.class.php 23810 2009-11-12 11:07:44Z Kris.Wallsmith $
*/
class jobActions extends sfActions
{
public function executeIndex(sfWebRequest $request)
{
$this->jobeet_jobs = Doctrine_Core::getTable('JobeetJob')
->createQuery('a')
->execute();
}
public function executeShow(sfWebRequest $request)
{
$this->jobeet_job = Doctrine_Core::getTable('JobeetJob')->find(array($request->getParameter('id')));
$this->forward404Unless($this->jobeet_job);
}
public function executeNew(sfWebRequest $request)
{
$this->form = new JobeetJobForm();
}
public function executeCreate(sfWebRequest $request)
{
$this->forward404Unless($request->isMethod(sfRequest::POST));
$this->form = new JobeetJobForm();
$this->processForm($request, $this->form);
$this->setTemplate('new');
}
public function executeEdit(sfWebRequest $request)
{
$this->forward404Unless($jobeet_job = Doctrine_Core::getTable('JobeetJob')->find(array($request->getParameter('id'))), sprintf('Object jobeet_job does not exist (%s).', $request->getParameter('id')));
$this->form = new JobeetJobForm($jobeet_job);
}

$this->forward404Unless($jobeet_job = Doctrine_Core::getTable('JobeetJob')->find(array($request->getParameter('id'))), sprintf('Object jobeet_job does not exist (%s).', $request->getParameter('id')));
$jobeet_job->delete();
$this->redirect('job/index');
}
protected function processForm(sfWebRequest $request, sfForm $form)
{
$form->bind($request->getParameter($form->getName()), $request->getFiles($form->getName()));
if ($form->isValid())
{
$jobeet_job = $form->save();
$this->redirect('job/edit?id='.$jobeet_job->get());
}
}
}
Puntare il browser a: http://localhost/jobeet/web/index.php/job per vedere il form in azione
2. Personalizziamo il template a: jobeet/apps/frontend/templates/layout.php

preg_replace() è deprecata, andrebbe sostituita nelle librerie Symfony con preg_replace_callback(), cancelliamo i warning testuali generati nel codice e tentiamo di correggere l’errore (https://gist.github.com/gitllermopalafox/0a8b60eaafede6af0b75)
