AjaxEntityType
, (*12)
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., (*13)
Enable in your config.yml (disabled by default):, (*14)
zenstruck_form:
form_types:
ajax_entity: true
There are several ways to use this type:, (*15)
-
Default - creates a hidden field type. It is up to the user to add functionality., (*16)
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):, (*17)
Enable the controller in your config.yml (disabled by default):, (*18)
zenstruck_form:
form_types:
ajax_entity_controller: true
Add the route to your routing.yml:, (*19)
zenstruck_form:
resource: "@ZenstruckFormBundle/Resources/config/ajax_entity_routing.xml"
Add to your form type:, (*20)
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., (*21)
-
Select2 with custom URL. This will create a Select2 widget for this field., (*22)
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:, (*23)
[
{"id":2004,"text":"dolorem"},
{"id":2008,"text":"inventore"}
]
-
class: The entity the field represents. Required.
-
url: The url that Select2 will send search queries to
-
property: The entity property to search by (Overrides url)
-
method: The custom repository method to call for searches (Overrides property)
-
placeholder: The Select2 placeholder text. Default: Choose an option
-
multiple: Whether this is allows for multiple values. Default: false
-
use_controller: Whether to use the bundled controller or not (``). Default: false
-
repo_method: For using a custom repository method. Default: null
-
extra_data: For adding extra data in the ajax request (only applicable when using repo_method). Default array()

form_types:
tunnel_entity: true
-

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:, (*30)
<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:, (*31)
-
.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 if required is false)

-
