I have managed to setup the symfony forms to work as standalone in my project. However i can only get it to work with twig. Is it possible for me to render the forms without twig?
The way i currently do it is:
#Controller
echo $twig->render('index.html.twig', array(
'form' => $form->createView(),
));
#Twig File
{{ form_widget(form) }}
Is it possible to render the form without twig?
Any help is greately appreciated
It is hard to find resources about how to use Symfony's form component 1) without Twig and 2) without Symfony.
I guess this is not recommended but I made this up for myself as a first starting point:
<?php
require 'vendor/autoload.php';
use Symfony\Component\Form\Forms;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\IntegerType;
$form = Forms::createFormFactory()->createBuilder()
->add('firstname', TextType::class, ['label' => 'My firstname'])
->add('age', IntegerType::class, ['label' => 'My age'])
->getForm();
$form->handleRequest(); // Looks into superglobals and detects if the user submitted the form, if so it submits the form with $form->submit()
if ($form->isSubmitted() && $form->isValid()) {
$data = $form->getData();
var_dump($data);
}
$formView = $form->createView();
?>
<html>
<body>
<form
action="<?php echo $form->getConfig()->getAction(); ?>"
method="<?php echo $form->getConfig()->getMethod(); ?>"
>
<?php foreach ($formView->getIterator() as $field) { ?>
<div>
<label
for="<?php echo $field->vars['id']; ?>"
>
<?php echo $field->vars['label']; ?>
</label>
<input
type="<?php echo $field->vars['block_prefixes'][1]; ?>"
id="<?php echo $field->vars['id']; ?>"
name="<?php echo $field->vars['full_name']; ?>"
value="<?php echo $field->vars['value']; ?>"
/>
<?php if ($field->vars['required']) { ?>
<span>This field is required</span>
<?php } ?>
</div>
<?php } ?>
<input type="submit" />
</form>
</body>
</html>
First you have to go to app/config and check if php is included as templating engine
templating:
engines: ['php', 'twig']
And here is one of the ways to render form with php:
echo $view['form']->form($form,array('attr' => array('class' => 'Form')));
There are plenty of examples for rendering forms in the symfony2 official site. You can render field by field or the full form as shown i my example.
