lithium\template\helper\Html::link()

public method

Creates an HTML link (<a />) or a document meta-link (<link />).

If $url starts with 'http://' or 'https://', this is treated as an external link. Otherwise, it is treated as a path to controller/action and parsed using the Router::match() method (where Router is the routing class dependency specified by the rendering context, i.e. lithium\template\view\Renderer::$_classes).

If $url is empty, $title is used in its place.

Parameters

  • string $title

    The content to be wrapped by an <a /> tag, or the title attribute of a meta-link <link />.

  • mixed $url

    Can be a string representing a URL relative to the base of your Lithium application, an external URL (starts with 'http://' or 'https://'), an anchor name starting with '#' (i.e. '#top'), or an array defining a set of request parameters that should be matched against a route in Router.

  • array $options

    The available options are:

    • 'escape' boolean: Whether or not the title content should be escaped. Defaults to true.
    • 'type' string: The meta-link type, which is looked up in Html::$_metaLinks. By default it accepts atom, rss and icon. If a type is specified, this method will render a document meta-link (<link />), instead of an HTML link (<a />).
    • any other options specified are rendered as HTML attributes of the element.

Returns

string

Returns an <a /> or <link /> element.
