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):

There are several ways to use this type:

1. Default - creates a hidden field type. It is up to the user to add functionality.

2. Select2 with built in entity finder (zendframework/zend-crypt required):

   Enable the controller in your config.yml (disabled by default):

   Add the route to your routing.yml:

   Add to your form type:

   Note: The URL is dynamically generated for each entity but is encrypted with the application's secret for security purposes.

3. Select2 with custom URL. This will create a Select2 widget for this field.

   The url endpoint receives the search string as a q request parameter and must return a json encoded array. Here is an example:

FormType options

• 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()

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.

1. Enable in your config.yml (disabled by default):

2. Add help option to your form fields

The widget html generated by the above example is as follows:

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 if required is false)
• .zenstruck-tunnel-select: button that initiates the entity selection

FormType options

• class: The entity the field represents. Required.
• callback: The javascript callback
• button_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.

1. Enable in your config.yml (disabled by default):

2. Add help option to your form fields

Group Type

This type allows you group large forms into tabs.

2. Add help option to your form fields

   Note: fields without a group will be in the first, default tab.

3. When creating your form view in your controller, wrap it with Zenstruck\Bundle\FormBundle\Form\GroupedFormView

   Note: to name your default tab to something other than Default, pass it as the second parameter to the GroupedFormView constructor.

4. In your template, include grouped_form.html.twig to render the form.

   Note: to use the wrapped form, use grouped_form.form

Add custom data to GroupedFormView

Initialize all helpers with:

PostLinkHelper

Allows a standard <a> tag to become a method="POST" link. Add the class method-post, method-post-confirm or method-delete to an <a> tag for it's href value to become a POST link.

• method-post: standard post link (no confirmation)
• method-post-confirm: method-post with a confirmation dialog that is customizable via the data-message attribute
• method-delete: cross browser compatible DELETE link with a "Are you sure you want to delete?" confirmation dialog

Enable with ZenstruckFormHelper.initPostLinkHelper()

FormCollectionHelper

Adds Symfony2 form collection 'add' and 'delete' button functionality. See the Symfony2 docs. This works out of the box when using the form_bootstrap_layout.html.twig form layout provided by this bundle.

Note: Do not add the javascript provided in the Symfony2 cookbook article
