将新的上下文变量添加到锂\\模板\\视图\\适配器\\文件

Question

I'd like to replicate the functionality of the $this->head() and $this->scripts() handlers to add $this->footer() . I understand that I can use Renderer::handlers() to register a new handler, but I'm not sure how I can extend the File::$_context property to add the new footer context.

So far, I assume I'd add the snippet below to an Html helper.

protected function _init() {
    parent::_init();

    if ($this->_context) {
        $ctx =& $this->_context;

        $this->_context->handlers(array(
            'footer' => function($footers) use (&$ctx) {
                    return "\n\t" . join("\n\t", $ctx['footer']) . "\n";
                }
        ));
    }
}

Perhaps I'm overthinking it, and should just extend my Html helper to replicate the functionality.

I haven't tested this, but with the way __call() works, you should be able to say $this->_context += ['footer' => []] inside _init() then call $this->footer("Foo!") to append.

When you're ready to render, $this->context("footer") should give you back an array of values.
