| protected _render ( string $method, string $string, array $params, array $options = [] ) : string | ||
| $method | string | name of method that is calling the render (for context filters) |
| $string | string | template key (in Helper::_strings) to render |
| $params | array | associated array of template inserts {:key} will be replaced by value |
| $options | array | Available options: - `'handlers'` _array_: Before inserting `$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. |
