3. Adding a Template

6. Creating a Module Skeleton > cd ~/myproject > php symfony generate:module frontend content >> dir+ ~/myproject/apps/frontend/modules/content/actions >> file+ ~/myproject/apps/frontend/modules/content/actions/actions.class.php >> dir+ ~/myproject/apps/frontend/modules/content/templates >> file+ ~/myproject/apps/frontend/modules/content/templates/indexSuccess.php >> file+ ~/myproject/test/functional/frontend/contentActionsTest.php >> tokens ~/myproject/test/functional/frontend/contentActionsTest.php >> tokens ~/myproject/apps/frontend/modules/content/actions/actions.class.php >> tokens ~/myproject/apps/frontend/modules/content/templates/indexSuccess.php

7. The Default Generated Action, in actions/actions.class.php <?php class contentActions extends sfActions { public function executeIndex() { $this->forward('default', 'module'); } }

9. Adding an Action <?php class contentActions extends sfActions { public function executeShow() { } } Adding an Action Is Like Adding an Execute Method to the Action Class

11. Use Alternative PHP Syntax in Template <p>Hello, world!</p> <?php if ($test) { echo &quot;<p>&quot;.time().&quot;</p>&quot;; } ?> The Usual PHP Syntax, Good for Actions, But Bad for Templates <p>Hello, world!</p> <?php if ($test): ?> <p><?php echo time(); ?></p> <?php endif; ?> The Alternative PHP Syntax, Good for Templates

12. Passing Information from the Action to The Template <?php class contentActions extends sfActions { public function executeShow() { $today = getdate(); $this->hour = $today['hours']; } } Setting an Action Attribute in the Action to Make It Available to the Template <p>Hello, world!</p> <?php if ($hour >= 18): ?> <p>Or should I say good evening? It is already <?php echo $hour ?>.</p> <?php endif; ?> The Template Has Direct Access to the Action Attributes

14. You will soon learn how to use them efficiently.

15. Linking to Another Action <a href=&quot;/frontend_dev.php/content/update?name=anonymous&quot;> I never say my name </a> Hyperlinks, the Classic Way <p>Hello, world!</p> <?php if ($hour >= 18): ?> <p>Or should I say good evening? It is already <?php echo $hour ?>.</p> <?php endif; ?> <form method=&quot;post&quot; action=&quot;<?php echo url_for('content/update') ?>&quot;> <label for=&quot;name&quot;>What is your name?</label> <input type=&quot;text&quot; name=&quot;name&quot; id=&quot;name&quot; value=&quot;&quot; /> <input type=&quot;submit&quot; value=&quot;Ok&quot; /> <?php echo link_to('I never say my name','content/update?name=anonymous') ?> </form> The link_to() , and url_for() Helpers

16. link_to() helpers // Option argument as an associative array <?php echo link_to('I never say my name', 'content/update?name=anonymous', array( 'class' => 'special_link', 'confirm' => 'Are you sure?', 'absolute' => true )) ?> // Option argument as a string <?php echo link_to('I never say my name', 'content/update?name=anonymous', 'class=special_link confirm=Are you sure? absolute=true') ?> // Both calls output the same => <a class=&quot;special_link&quot; onclick=&quot;return confirm('Are you sure?');&quot; href=&quot;http://localhost/frontend_dev.php/content/update/name/anonymous&quot;> I never say my name</a> Most Helpers Accept an Option Argument

17. Getting Information from the Request <?php class contentActions extends sfActions { // ... public function executeUpdate($request) { $this->name = $request->getParameter('name'); } } Getting Data from the Request Parameter in the Action If there is no data manipulation, use $sf_params object instead in template : <p>Hello, <?php echo $sf_params->get('name') ?>!</p>

19. $sf_params is more powerful Or ..... <p>Hello, <?php echo $sf_params->get('name', 'John Doe') ?>!</p> <?php if ($sf_params->has('name')): ?> <p>Hello, <?php echo $sf_params->get('name') ?>!</p> <?php else: ?> <p>Hello, John Doe!</p> <?php endif; ?> Testing the Existence of a Request Parameter in the Template
