Class: renderer_base - X-Ref
Simple base class for Moodle renderers.Tracks the xhtml_container_stack to use, which is passed in in the constructor.
Also has methods to facilitate generating HTML output.
| get_mustache() X-Ref |
| Return an instance of the mustache class. return: Mustache_Engine |
| __construct(moodle_page $page, $target) X-Ref |
| Constructor The constructor takes two arguments. The first is the page that the renderer has been created to assist with, and the second is the target. The target is an additional identifier that can be used to load different renderers for different options. param: moodle_page $page the page we are doing output for. param: string $target one of rendering target constants |
| render_from_template($templatename, $context) X-Ref |
| Renders a template by name with the given context. The provided data needs to be array/stdClass made up of only simple types. Simple types are array,stdClass,bool,int,float,string param: array|stdClass $context Context containing data for the template. return: string|boolean |
| render(renderable $widget) X-Ref |
| Returns rendered widget. The provided widget needs to be an object that extends the renderable interface. If will then be rendered by a method based upon the classname for the widget. For instance a widget of class `crazywidget` will be rendered by a protected render_crazywidget method of this renderer. If no render_crazywidget method exists and crazywidget implements templatable, look for the 'crazywidget' template in the same component and render that. param: renderable $widget instance with renderable interface return: string |
| add_action_handler(component_action $action, $id = null) X-Ref |
| Adds a JS action for the element with the provided id. This method adds a JS event for the provided component action to the page and then returns the id that the event has been attached to. If no id has been provided then a new ID is generated by {@link html_writer::random_id()} param: component_action $action param: string $id return: string id of element, either original submitted or random new if not supplied |
| has_started() X-Ref |
| Returns true is output has already started, and false if not. return: boolean true if the header has been printed. |

| Given an array or space-separated list of classes, prepares and returns the HTML class attribute value param: mixed $classes Space-separated string or array of classes return: string HTML class attribute value |
| pix_url($imagename, $component = 'moodle') X-Ref |
| Return the direct URL for an image from the pix folder. Use this function sparingly and never for icons. For icons use pix_icon or the pix helper in a mustache template. param: string $imagename the name of the icon. param: string $component specification of one plugin like in get_string() return: moodle_url |
| image_url($imagename, $component = 'moodle') X-Ref |
| Return the moodle_url for an image.

The imagename is for historical reasons a relative path name, it may be changed later for core images. It is recommended to not use subdirectories in plugin and theme pix directories. There are three types of images: 1/ theme images - stored in theme/mytheme/pix/, use component 'theme' 2/ core images - stored in /pix/, overridden via theme/mytheme/pix_core/ 3/ plugin images - stored in mod/mymodule/pix, overridden via theme/mytheme/pix_plugins/mod/mymodule/, example: image_url('comment', 'mod_glossary') param: string $imagename the pathname of the image param: string $component full plugin name (aka component) or 'theme' return: moodle_url |
