lithium\template\Helper::_render()

protected method

Render a string template after applying context filters Use examples in the Html::link() method: return $this->_render(__METHOD__, 'link', compact('title', 'url', 'options'), $scope);

Parameters

string $method
name of method that is calling the render (for context filters)
string $string
template key (in Helper::_strings) to render
array $params
associated array of template inserts {:key} will be replaced by value
array $options
Available options:
- 'handlers' array: Before inserting $params inside the string template, $this->_context's handlers are applied to each value of $params according to the key (e.g $params['url'], which is processed by the 'url' handler via $this->_context->applyHandler()). The 'handlers' option allow to set custom mapping beetween $params's key and $this->_context's handlers. e.g. the following handler: 'handlers' => array('url' => 'path') will make $params['url'] to be processed by the 'path' handler instead of the 'url' one.

Returns

string
