How To render Silex Forms in Smarty Template? - php

Question

I just stuck at a point.
To render Forms in Smarty Template.
Well, smarty is well configured in my silex project.
here is the Code in my controller class.
$loginForm = $app['form.factory']
->createBuilder(new Form\UserLogin())
->getForm();
$app['smarty']->assign('loginForm', $loginForm->createView());
return $app['smarty']->render('login.tpl');
Here is the code in my tpl file
{block name="headline"}
<h1>User Login</h1>
{/block}
{block name="content"}
<div>
{form_widget(loginForm)}
</div>
{/block}
And i am getting this exception.
SmartyCompilerException:
Syntax Error in template "/home/Symfony/demo/App/View/login.tpl" on line 8
"{form_widget(loginForm)}" unknown function "form_widget"
Edit:
Ok i found the issue but not getting the solution.
Following is SmartyServiceProvider Class.
<?php
namespace App\ServiceProvider;
use Silex\Application;
use \Symfony\Component\HttpFoundation\Request;
use Silex\ServiceProviderInterface;
use App\Classes\Smarty;
use NoiseLabs\Bundle\SmartyBundle\Form\SmartyRendererInterface;
use \NoiseLabs\Bundle\SmartyBundle\Extension\AbstractExtension;
use \NoiseLabs\Bundle\SmartyBundle\Extension\FormExtension;
use \NoiseLabs\Bundle\SmartyBundle\Form;
class SmartyServiceProvider implements ServiceProviderInterface
{
public function register(Application $app)
{
$app['smarty.auto-render'] = true;
$app['smarty.extension'] = $app->protect(
function (AbstractExtension $extension, Smarty $smarty = null) use ($app) {
if ($smarty == null) {
$smarty = $app['smarty'];
}
/** #var $plugin \NoiseLabs\Bundle\SmartyBundle\Extension\Plugin\AbstractPlugin */
/** #var $filter \NoiseLabs\Bundle\SmartyBundle\Extension\Filter\AbstractFilter */
foreach ($extension->getPlugins() as $plugin) {
//print $plugin->getName() . " | " . $plugin->getType() . "<br>";
$smarty->registerPlugin($plugin->getType(), $plugin->getName(), $plugin->getCallback());
}
foreach ($extension->getFilters() as $filter) {
$smarty->registerFilter($filter->getType(), $filter->getCallback());
}
}
);
$app['smarty.extensions'] = $app->protect(
function (array $extensions, Smarty $smarty = null) use ($app) {
foreach ($extensions as $extension) {
$app['smarty.extension']($extension, $smarty);
}
}
);
$app['smarty'] = $app->share(
function () use ($app) {
$app['directory.smarty.plugins'] = $app['directory.root.app'] . '/Classes/Smarty/Plugins';
$smarty = isset($app['smarty.instance']) ? $app['smarty.instance'] : new Smarty(
$app,
isset($app['smarty.primary.template.dir'])
? $app['smarty.primary.template.dir']
: $app['directory.root.view'],
false
);
if (isset($app["smarty.options"]) && is_array($app["smarty.options"])) {
foreach ($app["smarty.options"] as $smartyOptionName => $smartyOptionValue) {
$smarty->$smartyOptionName = $smartyOptionValue;
}
}
$smarty->assign("app", $app);
if (isset($app['smarty.configure'])) {
$app['smarty.configure']($smarty);
}
$extensions = [];
//$extensions[] = new \NoiseLabs\Bundle\SmartyBundle\Extension\FormExtension();
$extensions[] = new \NoiseLabs\Bundle\SmartyBundle\Extension\RoutingExtension($app['url_generator']);
$extensions[] = new \App\Classes\Smarty\HookExtension();
$app['smarty.extensions']($extensions, $smarty);
return $smarty;
}
);
}
public function boot(Application $app)
{
}
}
Here in that class i have loaded extensions of SmartyBundle here.
Here I'll have to load FormExtensions.
$extensions = [];
$extensions[] = new \NoiseLabs\Bundle\SmartyBundle\Extension\FormExtension('Don't know how to get SmartyRendererInterface instance here');
$extensions[] = new \NoiseLabs\Bundle\SmartyBundle\Extension\RoutingExtension($app['url_generator']);
$extensions[] = new \App\Classes\Smarty\HookExtension();
$app['smarty.extensions']($extensions, $smarty);

The correct syntax for the Form Widget is:
{form_widget form=$loginForm}
From your example it's not clear the out from $loginForm->createView() and you're lacking the form tags ( ie )that normally surround the Form widget. If the createView includes these you make be not need the form widget and just need to output the entire form HTML as:
{$loginForm}
