How to Bind Embedded Forms in Symfony
Embedded forms in the Web programming framework Symfony give Web engineers a unique way to add slick-looking forms to their Web pages. Binding the embedded forms to your Web page is done when you add the embedded form code to the Web page's code. One of the primary advantages of using an embedded form in Symfony is that it can call the same database that the rest of the site uses to store form entries or a different database altogether.

Open your preferred code editor or a plaintext editing application and create a new document or open the code of the page that you wish to bind the form to.

Create a new event module responsible with binding the form to the page:
<?php // apps/frontend/modules/event/actions/actions.class.php
class eventActions extends sfActions{
public function executeIndex(sfWebRequest $request){
$this->events = Doctrine_Core::getTable('Event')->findAll();
}
} -

Set up the embedded form's structure by using the executeEdit function and by specifying the form template that the embedded form uses:
public function executeEdit(sfWebRequest $request){
$this->forward404Unless($event = Doctrine::getTable('Event')->find(array($request->getParameter('id'))), sprintf('Event does not exist (%s).', $request->getParameter('id')));
$this->form = new EventForm($event);
}
<!--apps/frontend/modules/templates/editSuccess.php-->
<h2>Form Title</h2>
<form action="<?php echo url_for('@submit') ?>" method="post">
<?php echo $form->renderHiddenFields() ?>
<?php echo $form['title']->renderLabel()?> <?php echo $form['title']->renderError()?> <?php echo $form['title'] ?>
<input type="submit" value="Save" />
</form>
<a href="<?php echo url_for('@homepage')?>">Back to index</a> -

Save the practice code you've created and use it as a template going forward when you need to bind a Symfony embedded form on your page.
