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');
  }

  {

    $this->form = new JobeetJobForm($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')));
    $this->form = new JobeetJobForm($jobeet_job);

    $this->processForm($request, $this->form);

    $this->setTemplate('edit');
  }

  public function executeDelete(sfWebRequest $request)
  {
    $request->checkCSRFProtection();

    $this->forward404Unless($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());
    }
  }
}

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)
