|

* Theme override for a field.
|
||||
*
|
||||
* To override output, copy the "field.html.twig" from the templates directory
|
||||
* to your theme's directory and customize it, just like customizing other
|
||||
* Drupal templates such as page.html.twig or node.html.twig.
|
||||
*
|
||||
* Instead of overriding the theming for all fields, you can also just override
|
||||
* theming for a subset of fields using
|
||||
* @link themeable Theme hook suggestions. @endlink For example,
|
||||
* here are some theme hook suggestions that can be used for a field_foo field
|
||||
* on an article node type:
|
||||
* - field--node--field-foo--article.html.twig
|
||||
* - field--node--field-foo.html.twig
|
||||
* - field--node--article.html.twig
|
||||
* - field--field-foo.html.twig
|
||||
* - field--text-with-summary.html.twig
|
||||
* - field.html.twig
|
||||
*
|
||||
* Available variables:
|
||||
* - attributes: HTML attributes for the containing element.
|
||||
* - label_hidden: Whether to show the field label or not.
|
||||
* - title_attributes: HTML attributes for the title.
|
||||
* - label: The label for the field.
|
||||
* - multiple: TRUE if a field can contain multiple items.
|
||||
* - items: List of all the field items. Each item contains:
|
||||
* - attributes: List of HTML attributes for each item.
|
||||
* - content: The field item's content.
|
||||
* - entity_type: The entity type to which the field belongs.
|
||||
* - field_name: The name of the field.
|
||||
* - field_type: The type of the field.
|
||||
* - label_display: The display settings for the label.
|
||||

||||
* @see template_preprocess_field()

/**
|
||||
* @file
|
||||
* Theme override to display a node.
|
||||
*
|
||||
* Available variables:
|
||||
* - node: The node entity with limited access to object properties and methods.
|
||||
* Only method names starting with "get", "has", or "is" and a few common
|
||||
* methods such as "id", "label", and "bundle" are available. For example:
|
||||
* - node.getCreatedTime() will return the node creation timestamp.
|
||||
* - node.hasField('field_example') returns TRUE if the node bundle includes
|
||||
* field_example. (This does not indicate the presence of a value in this
|
||||
* field.)
|
||||
* - node.isPublished() will return whether the node is published or not.
|
||||
* Calling other methods, such as node.delete(), will result in an exception.
|
||||
* See \Drupal\node\Entity\Node for a full list of public properties and
|
||||
* methods for the node object.
|
||||
* - label: The title of the node.
|
||||
* - content: All node items. Use {{ content }} to print them all,
|
||||
* or print a subset such as {{ content.field_example }}. Use
|
||||
* {{ content|without('field_example') }} to temporarily suppress the printing
|
||||
* of a given child element.
|
||||
* - author_picture: The node author user entity, rendered using the "compact"
|
||||
* view mode.
|
||||
* - metadata: Metadata for this node.
|
||||
* - date: Themed creation date field.
|
||||
* - author_name: Themed author name field.
|
||||
* - url: Direct URL of the current node.
|
||||
* - display_submitted: Whether submission information should be displayed.
|
||||
* - attributes: HTML attributes for the containing element.
|
||||
* The attributes.class element may contain one or more of the following
|
||||
* classes:
|
||||
* - node: The current template type (also known as a "theming hook").
|
||||
* - node--type-[type]: The current node type. For example, if the node is an
|
||||
* "Article" it would result in "node--type-article". Note that the machine
|
||||
* name will often be in a short form of the human readable label.
|
||||
* - node--view-mode-[view_mode]: The View Mode of the node; for example, a
|
||||
* teaser would result in: "node--view-mode-teaser", and
|
||||
* full: "node--view-mode-full".
|
||||
* The following are controlled through the node publishing options.
|
||||
* - node--promoted: Appears on nodes promoted to the front page.
|
||||
* - node--sticky: Appears on nodes ordered above other non-sticky nodes in
|
||||
* teaser listings.
|
||||
* - node--unpublished: Appears on unpublished nodes visible only to site
|
||||
* admins.
|
||||
* - title_attributes: Same as attributes, except applied to the main title
|
||||
* tag that appears in the template.
|
||||
* - content_attributes: Same as attributes, except applied to the main
|
||||
* content tag that appears in the template.
|
||||
* - author_attributes: Same as attributes, except applied to the author of
|
||||
* the node tag that appears in the template.
|
||||
* - title_prefix: Additional output populated by modules, intended to be
|
||||
* displayed in front of the main title tag that appears in the template.
|
||||
* - title_suffix: Additional output populated by modules, intended to be
|
||||
* displayed after the main title tag that appears in the template.
|
||||
* - view_mode: View mode; for example, "teaser" or "full".
|
||||
* - teaser: Flag for the teaser state. Will be true if view_mode is 'teaser'.
|
||||
* - page: Flag for the full page state. Will be true if view_mode is 'full'.
|
||||
* - readmore: Flag for more state. Will be true if the teaser content of the
|
||||
* node cannot hold the main body content.
|
||||
* - logged_in: Flag for authenticated user status. Will be true when the
|
||||
* current user is a logged-in member.
|
||||
* - is_admin: Flag for admin user status. Will be true when the current user
|
||||
* is an administrator.
|
||||
*
|
||||
* @see template_preprocess_node()
|
||||
*
|
||||
* @todo Remove the id attribute (or make it a class), because if that gets
|
||||
* rendered twice on a page this is invalid CSS for example: two lists
|
||||
* in different view modes.
