Twitter Bootstrap form layout
To use, do one of the following:
-
Add for a single template:
{# for bootstrap 2.x #} {% form_theme form 'ZenstruckFormBundle:Twitter:form_bootstrap_layout.html.twig' %} {# for bootstrap 3.x #} {% form_theme form 'ZenstruckFormBundle:Twitter:form_bootstrap3_layout.html.twig' %}
-
Add globally in your
config.yml
:twig: form: resources: # for bootstrap 2.x - 'ZenstruckFormBundle:Twitter:form_bootstrap_layout.html.twig' # for bootstrap 3.x - 'ZenstruckFormBundle:Twitter:form_bootstrap3_layout.html.twig'
FormType Extensions
AjaxEntityType
Creates a 1-m
or m-m
entity association field. This type simply creates a hidden field that takes
an either 1 or multiple comma separated entity ids. Note: Ensure the entity has __toString()
defined.
Enable in your config.yml
(disabled by default):
zenstruck_form: form_types: ajax_entity: true
There are several ways to use this type:
-
Default - creates a hidden field type. It is up to the user to add functionality.
use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilderInterface; class MyFormType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder ->add('name', 'zenstruck_ajax_entity', array( 'class' => 'AppBundle:MyEntity' // ensure MyEntity::__toString() is defined )) ; } // ... }
-
Select2 with built in entity finder (
zendframework/zend-crypt
required):Enable the controller in your
config.yml
(disabled by default):zenstruck_form: form_types: ajax_entity_controller: true
Add the route to your
routing.yml
:zenstruck_form: resource: "@ZenstruckFormBundle/Resources/config/ajax_entity_routing.xml"
Add to your form type:
use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilderInterface; class MyFormType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder ->add('name', 'zenstruck_ajax_entity', array( 'class' => 'AppBundle:MyEntity', // ensure MyEntity::__toString() is defined 'use_controller' => true, 'property' => 'name', // the entity property to search by // 'repo_method' => 'findActive' // for using a custom repository method // 'extra_data' => array() // for adding extra data in the ajax request (only applicable when using repo_method) )) ; } // ... }
Note: The URL is dynamically generated for each entity but is encrypted with the application's
secret
for security purposes. -
Select2 with custom URL. This will create a Select2 widget for this field.
use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilderInterface; class MyFormType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder ->add('name', 'zenstruck_ajax_entity', array( 'class' => 'AppBundle:MyEntity', // ensure MyEntity::__toString() is defined 'url' => '/myentity/find' )) ; } // ... }
The url endpoint receives the search string as a
q
request parameter and must return a json encoded array. Here is an example:[ {"id":2004,"text":"dolorem"}, {"id":2008,"text":"inventore"} ]
FormType options
class
: The entity the field represents. Required.url
: The url that Select2 will send search queries toproperty
: The entity property to search by (Overridesurl
)method
: The custom repository method to call for searches (Overridesproperty
)placeholder
: The Select2 placeholder text. Default: Choose an optionmultiple
: Whether this is allows for multiple values. Default: falseuse_controller
: Whether to use the bundled controller or not (``). Default: falserepo_method
: For using a custom repository method. Default: nullextra_data
: For adding extra data in the ajax request (only applicable when using repo_method). Default array()
Select2 Javascript Helper
Enables the Select2 widget for AjaxEntityType
. Requires
Select2.
Enable with ZenstruckFormHelper.initSelect2Helper()
TunnelEntityType
Creates an entity association field with a select button. A javascript callback for the select button may be defined. Can be used for opening a dialog to choose an entity.
-
Enable in your
config.yml
(disabled by default):zenstruck_form: form_types: tunnel_entity: true
-
Add help option to your form fields
use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilderInterface; class MyFormType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder ->add('name', 'zenstruck_tunnel_entity', array( 'class' => 'AppBundle:MyEntity', 'callback' => 'MyApp.selectMyEntity', 'required' => false )) ; } // ... }
The widget html generated by the above example is as follows:
<div class="input-append zenstruck-tunnel-widget"> <input type="hidden" class="zenstruck-tunnel-id" /> <span class="uneditable-input zenstruck-tunnel-title">{{ title }}</span> <a href="#" class="btn zenstruck-tunnel-clear"><b class="icon-remove"></b></a> <a href="#" class="btn zenstruck-tunnel-select" data-callback="MyApp.selectMyEntity">Select...</a> </div>
Your javascript can hook into the clear button and select button. Here are the useful classes:
.zenstruck-tunnel-id
: id of the selected entity.zenstruck-tunnel-title
: title of the selected entity.zenstruck-tunnel-clear
: button that clears the title/id (only available ifrequired
isfalse
).zenstruck-tunnel-select
: button that initiates the entity selection
FormType options
class
: The entity the field represents. Required.callback
: The javascript callbackbutton_text
: The text for the select button. Default: Select...
Tunnel Javascript Helper
Adds events to the clear and select buttons. The select button calls the callback
defined in the type options.
The callback receives the following parameters:
id
: the id of the currently selected entity (if any)element
: the hidden input element
Enable with ZenstruckFormHelper.initTunnelHelper()
HelpType
Allow you to add help messages to your form fields.
-
Enable in your
config.yml
(disabled by default):zenstruck_form: form_types: help: true
-
Add help option to your form fields
use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilderInterface; class MyFormType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder ->add('name', 'text', array( 'help' => 'Your full name' )) ; } // ... }
Group Type
This type allows you group large forms into tabs.
-
Enable in your
config.yml
(disabled by default):zenstruck_form: form_types: group: true
-
Add help option to your form fields
use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilderInterface; class MyFormType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder ->add('name', 'text', array( 'group' => 'Foo' )) ->add('name', 'text', array( 'group' => 'Bar' )) ; } // ... }
Note: fields without a group will be in the first, default tab.
-
When creating your form view in your controller, wrap it with
Zenstruck\Bundle\FormBundle\Form\GroupedFormView
class MyController extends Controller { public function newAction(Request $request) { // ... return array( 'grouped_form' => new \Zenstruck\Bundle\FormBundle\Form\GroupedFormView($form->createView()) ); } }
Note: to name your default tab to something other than Default, pass it as the second parameter to the
GroupedFormView
constructor. -
In your template, include
grouped_form.html.twig
to render the form.<form method="post" {{ form_enctype(grouped_form.form) }}> {% include 'ZenstruckFormBundle:Twitter:grouped_form.html.twig' with { 'grouped_form': grouped_form } %} </form>
Note: to use the wrapped form, use
grouped_form.form
Add custom data to GroupedFormView
// .. $groupedForm = new \Zenstruck\Bundle\FormBundle\Form\GroupedFormView($form->createView()); $groupedForm->setData('foo', 'bar');
In your template:
{# ... #} {{ grouped_form.data('foo') }} {# returns bar #}
Custom group order
$groupedForm = new GroupedFormView($form->createView(), 'Default', array( 'Bar', 'Foo', 'Default' ));
Theme Type
Allow you to add theme options to your form fields. The theme_options
variable will be
available in your form theme. The bootstrap3 theme currently utilizes.
-
Enable in your
config.yml
(disabled by default):zenstruck_form: form_types: theme: true

use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilderInterface; class MyFormType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder ->add('name', 'text', array( 'theme_options' => array('control_width' => 'col-md-6') )) ; } // ... }
Miscellaneous Javascript helpers
This bundle comes with a set of useful javascript helpers. To enable, add the following javascipt file (or add to your assetic javascripts):

Initialize all helpers with:
$(function() { ZenstruckFormHelper.initialize(); });
PostLinkHelper
