- 10 core/lib/Drupal/Core/Render/Element/RenderElementBase.php \Drupal\Core\Render\Element\RenderElementBase
Provides a base class for render element plugins.
Render elements are referenced in render arrays; see the Render API topic for an overview of render arrays and render elements.
The elements of render arrays are divided up into properties (whose keys start with #) and children (whose keys do not start with #). The properties provide data or settings that are used in rendering. Some properties are specific to a particular type of render element, some are available for any render element, and some are available for any form input element. A list of the properties that are available for all render elements follows; the properties that are for all form elements are documented on \Drupal\Core\Render\Element\FormElementBase, and properties specific to a particular element are documented on that element's class. See the Render API topic for a list of the most commonly-used properties.
Many of the properties are strings that are displayed to users. These strings, if they are literals provided by your module, should be internationalized and translated; see the Internationalization topic for more information. Note that although in the properties list that follows, they are designated to be of type string, they would generally end up being \Drupal\Core\StringTranslation\TranslatableMarkup objects instead.
Here is the list of the properties used during the rendering of all render elements. These are available as properties on the render element (handled by magic setter/getter) and also the render array starting with a # character. For example $element['#access'] or $elementObject->access.
@property bool|\Drupal\Core\Access\AccessResultInterface $access Whether the element is accessible or not. When the value is FALSE (if boolean) or the isAllowed() method returns FALSE (if AccessResultInterface), the element is not rendered and user-submitted values are not taken into consideration. @property callable $access_callback A callable or function name to call to check access. Argument: element. @property array<string> $allowed_tags Array of allowed HTML tags for XSS filtering of #markup, #prefix, #suffix, etc. @property array $attached Array of attachments associated with the element. See the "Attaching libraries in render arrays" section of the Render API topic for an overview, and \Drupal\Core\Render\AttachmentsResponseProcessorInterface::processAttachments for a list of what this can contain. Besides this list, it may also contain a 'placeholders' element; see the Placeholders section of the Render API topic for an overview. @property array $attributes HTML attributes for the element. The first-level keys are the attribute names, such as 'class', and the attributes are usually given as an array of string values to apply to that attribute (the rendering system will concatenate them together into a string in the HTML output). @property array $cache Cache information. See the Caching section of the Render API topic for more information. @property array $children Array of child elements of this element. Set and used during the rendering process. @property bool $create_placeholder TRUE if the element has placeholders that are generated by #lazy_builder callbacks. Set internally during rendering in some cases. See also #attached. @property bool $defaults_loaded Set to TRUE during rendering when the defaults for the element #type have been added to the element. @property mixed $value A value that cannot be edited by the user. @property bool $has_garbage_value @internal Set to TRUE to indicate that the #value property of an element should not be used or processed. @property string $id The HTML ID on the element. This is automatically set for form elements, but not for all render elements; you can override the default value or add an ID by setting this property. @property array<callable, array<scalar>> $lazy_builder Array whose first element is a lazy building callback (callable), and whose second is an array of scalar arguments to the callback. To use lazy building, the element array must be very simple: no properties except #lazy_builder, #cache, #weight, and #create_placeholder, and no children. A lazy builder callback typically generates #markup and/or placeholders; see the Placeholders section of the Render API topic for information about placeholders. @property string $markup During rendering, this will be set to the HTML markup output. It can also be set on input, as a fallback if there is no theming for the element. This will be filtered for XSS problems during rendering; see also #plain_text and #allowed_tags. @property string $plain_text Elements can set this instead of #markup. All HTML tags will be escaped in this text, and if both #plain_text and #markup are provided, #plain_text is used. @property array<callable> $post_render Array of callables or function names, which are called after the element is rendered. Arguments: rendered element string, children. @property array<callable> $pre_render Array of callables or function names, which are called just before the element is rendered. Argument: $element. Return value: an altered $element. @property string $prefix Text to render before the entire element output. See also #suffix. If it is not already wrapped in a safe markup object, will be filtered for XSS safety. @property bool $printed Set to TRUE when an element and its children have been rendered. @property bool $render_children @internal Set to FALSE by the rendering process if the #theme call should be bypassed (normally, the theme is used to render the children). Set to TRUE by the rendering process if the children should be rendered by rendering each one separately and concatenating. @property string $suffix Text to render after the entire element output. See also #prefix. If it is not already wrapped in a safe markup object, will be filtered for XSS safety. @property string $theme Name of the theme hook to use to render the element. A default is generally set for elements; users of the element can override this (typically by adding __suggestion suffixes). @property array<string> $theme_wrappers Array of theme hooks, which are invoked after the element and children are rendered, and before #post_render functions. @property string $type The machine name of the type of render/form element. @property float $weight The sort order for rendering, with lower numbers coming before higher numbers. Default if not provided is zero; elements with the same weight are rendered in the order they appear in the render array.
