editor_image_upload_settings_form

editor_image_upload_settings_form(Editor $editor)

Subform constructor to configure the text editor's image upload settings.

Each text editor plugin that is configured to offer the ability to insert images and uses EditorImageDialog for that, should use this form to update the text editor's configuration so that EditorImageDialog knows whether it should allow the user to upload images.

Parameters

\Drupal\editor\Entity\Editor $editor: The text editor entity that is being edited.

Return value

array The image upload settings form.
