WP_Customize_Manager::__construct( array $args = array() )

In this article

Constructor.

Parameters

$argsarrayoptional
Args.
  • changeset_uuid null|string|false
    Changeset UUID, the post_name for the customize_changeset post containing the customized state.
    Defaults to null resulting in a UUID to be immediately generated. If false is provided, then then the changeset UUID will be determined during after_setup_theme: when the customize_changeset_branching filter returns false, then the default UUID will be that of the most recent customize_changeset post that has a status other than 'auto-draft', 'publish', or 'trash'. Otherwise, if changeset branching is enabled, then a random UUID will be used.
  • theme string
    Theme to be previewed (for theme switch). Defaults to customize_theme or theme query params.
  • messenger_channel string
    Messenger channel. Defaults to customize_messenger_channel query param.
  • settings_previewed bool
    If settings should be previewed. Defaults to true.
  • branching bool
    If changeset branching is allowed; otherwise, changesets are linear. Defaults to true.
  • autosaved bool
    If data from a changeset’s autosaved revision should be loaded if it exists. Defaults to false.
