如何将TWIG输出渲染为变量供以后使用(symfony2)?
而不是像这样在我的TWIG中对每张幻灯片进行这种渲染(见第6行):
{# loop out the slides #}
{% for c in contents %}
{% set i=i+1 %} {# increase slide number #}
<div id="slide{{ i }}" class="slide" style="z-index:{{ i }};">
{# the slide itself, rendered by it's own template #}
{% include 'BizTVArchiveBundle:ContentTemplate:'~c.template~'/view.html.twig' with {'contents': c, 'ordernumber': i} %}
</div>
{% endfor %}
...相反,我想把所有这些逻辑都保留在控制器中,只是为了向视图提供一系列现成的幻灯片。我该怎么做(见第9行):
//do stuff...
foreach ($container->getContent() as $c) {
$content[$i]['title'] = $c->getTitle();
$content[$i]['sort'] = $c->getSortOrder();
$content[$i]['data'] = $c->getData();
$content[$i]['template'] = $c->getTemplate()->getId();
$content[$i]['duration'] = $this->extract_seconds($c);
$content[$i]['html'] = $this->render('BizTVArchiveBundle:ContentTemplate:'.$content[$i]['template'].'/view.html.twig', array(
'contents'=> $content[$i],
'ordernumber' => 99,
));
}
它目前给我的一切($content[$i]['html']的内容)是
{"headers":{}}
