Symfony 1.4.20 – Database – Caricare i Dati Iniziali

Come caricare automaticamente i dati iniziali nel database utilizzando Symfony 1.4.22

0. Continuiamo dalla lezione precedente a: http://www.lucedigitale.com/blog/creare-un-database-orm-doctrine/

1. Creiamo un file YAML con dei dati dummies, creiamo wamp64/www/jobeet/data/fixtures/categories.yml

2. Carichiamo i dati nel DB
cmd.exe -> C:\wamp64\www\jobeet>symfony doctrine:data-load

Aprire phpMyAdmin, ora i dati sono presenti nel database

3. Generiamo form, filtri, modelli, e cancelliamo e ricreiamo il database con tutte le tabelle.
cmd.exe -> C:\wamp64\www\jobeet>symfony doctrine:build –all –and-load

Symfony 1.4.20 – Database – Form Accesso Dati

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

/**

 *

 * @author     Your name here

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('edit');
  }

  {
    $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());
    }
  }
}

Puntare il browser a: http://localhost/jobeet/web/index.php/job per vedere il form in azione

Symfony 1.4.22 – Contact Form Semplice

Come creare con Symfony 1.4.22 un semplice form per i contatti.

Form dentro al Controller

1. apps/modules/contenuto/actions/actions.class.php


<?php

class contenutoActions extends sfActions // estende la classe Symfony
{
  public function executeContact($request) // crea la pagina http://localhost/jobeet/web/contenuto/contact

      $this->form = new sfForm(); // istanzia la classe di Symfony per la creazione dei form
      // setta i widget, cioè il tipo di campo e i parametri
      $this->form->setWidgets(array(
        'name'    => new sfWidgetFormInputText(),
        'email'   => new sfWidgetFormInputText(array('default' => 'me@example.com')),
        'subject' => new sfWidgetFormChoice(array('choices' => array('Subject A', 'Subject B', 'Subject C'))),
        'message' => new sfWidgetFormTextarea(),
      ));
      // la richiesta inviata a contactSuccess.php sarà un oggetto composto da array
      // l'oggetto è contenuto nella variabile  - form - in contactSuccess.php sarà - echo $form -
    }
}// END class

2. apps/modules/contenuto/templates/contactSuccess.php


<?php echo $form->renderFormTag('contenuto/contact') ?>
  <table>
    <?php echo $form ?>
    <tr>
      <td colspan="2">

Symfony 1.4.22 – Layout

Il layout contiene gli elementi HTML comuni a tutte le pagine del sito.
La struttura finale del sito sarà composta dalla combinazione layout + template.

Il layout in Symfony 1.4.22 è il file in:
jobeet/apps/frontend/templates/layout.php


<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
  <head>
    <?php include_http_metas() ?>
    <?php include_metas() ?>
    <?php include_title() ?>
    <link rel="shortcut icon" href="/favicon.ico" />
    <?php include_stylesheets() ?>
    <?php include_javascripts() ?>
  </head>
  <body>
    <?php echo $sf_content ?>
  </body>
</html>

La parte più interessante è: 


<?php echo $sf_content ?>

La variabile $sf_content contiene HTML generato dall’azione di Symfony.

Di default, il task generate:project ha creato tre cartelle per i file degli elementi grafici:
– web/images/
– web/css/
– web/js/

In Symfony è possibile definire diversi layout, vediamo un esempio pratico.

actions.class.php


<?php
 
class contenutoActions extends sfActions // estende la classe Symfony
{ 
  public function executePageone() // http://localhost/jobeet/web/frontend_dev.php/contenuto/pageone
  {
  }
   public function executePagetwo() // http://localhost/jobeet/web/frontend_dev.php/contenuto/pagetwo
  {
      $this->setLayout('mio_layout');
  }
}// END class
