array calculateDependencies()

Calculates dependencies for the configured plugin.

Dependencies are saved in the plugin's configuration entity and are used to determine configuration synchronization order. For example, if the plugin integrates with specific user roles, this method should return an array of dependencies listing the specified roles.

Return Value

array

An array of dependencies grouped by type (config, content, module, theme). For example: @code array( 'config' => array('user.role.anonymous', 'user.role.authenticated'), 'content' => array('node:article:f0a189e6-55fb-47fb-8005-5bef81c44d6d'), 'module' => array('node', 'user'), 'theme' => array('seven'), ); @endcode

protected string[] getSourceFieldOptions()

Get the source field options for the media type form.

This returns all fields related to media entities, filtered by the allowed field types in the media source annotation.

Return Value

string[]

A list of source field options for the media type form.

array buildConfigurationForm(array $form, FormStateInterface $form_state)

Form constructor.

Plugin forms are embedded in other forms. In order to know where the plugin form is located in the parent form, #parents and #array_parents must be known, but these are not available during the initial build phase. In order to have these properties available when building the plugin form's elements, let this method return a form element that has a #process callback and build the rest of the form in the callback. By the time the callback is executed, the element's #parents and #array_parents properties will have been set by the form API. For more documentation on #parents and

array_parents, see \Drupal\Core\Render\Element\FormElement.

Parameters

array $form

An associative array containing the initial structure of the plugin form.

FormStateInterface $form_state

The current state of the form. Calling code should pass on a subform state created through \Drupal\Core\Form\SubformState::createForSubform().

Return Value

array

The form structure.

validateConfigurationForm(array $form, FormStateInterface $form_state)

Form validation handler.

Parameters

array $form

An associative array containing the structure of the plugin form as built by static::buildConfigurationForm().

FormStateInterface $form_state

The current state of the form. Calling code should pass on a subform state created through \Drupal\Core\Form\SubformState::createForSubform().

submitConfigurationForm(array $form, FormStateInterface $form_state)

Form submission handler.

Parameters

array $form

An associative array containing the structure of the plugin form as built by static::buildConfigurationForm().

FormStateInterface $form_state

The current state of the form. Calling code should pass on a subform state created through \Drupal\Core\Form\SubformState::createForSubform().
