如何将 TWIG 输出渲染为变量供以后使用(symfony2)? [英] How to render TWIG output to a variable for later use (symfony2)?

问题描述

而不是像这样对我的 TWIG 中的每张幻灯片进行渲染(参见第 6 行):

{# 循环播放幻灯片 #}{% for c in content %}{% set i=i+1 %} {#增加幻灯片数量#}<div id="slide{{ i }}" class="slide" style="z-index:{{ i }};">{# 幻灯片本身，由它自己的模板渲染 #}{% 包含 'BizTVArchiveBundle:ContentTemplate:'~c.template~'/view.html.twig' 和 {'contents': c, 'ordernumber': i} %}

{% 结束为 %}

...相反，我想将所有这些逻辑保留在控制器中，只将一组准备好的幻灯片传递给视图.我该怎么做(见第 9 行):

//做事...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[$i]['template'].'/view.html.twig', array('内容'=>$content[$i],'订单号' =>99,));}

此刻它给我的一切($content[$i]['html'] 的内容)是

{"headers":{}}

解决方案

如果你包括更好模板中的模板，这样您就可以将模板渲染保留在视图层中，并将逻辑保留在控制器层中.

好吧，如果你真的想要它......

您可以使用 2 个服务来做到这一点:twig 正在使用 Twig_Environment 或 templating.engine.twig 这是一个模板层构建在 Symfony2 for Twig 中，这可以很容易地切换到 templating.engine.php.

如果你使用 twig 服务，你可以看到 the twig docs使用方法:

$template = $this->get('twig')->render('/full/path/to/Resources/views/'.$content[$i]['template'].'/view.html.twig', array(...));

如果您使用 templating.engine.twig 服务，请参阅 模板关于如何使用它的文档，与 Twig_Environment 几乎完全相同.

Instead of doing this rendering of each slide in my TWIG like this (see line 6):

{# 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 %}

...Instead I would like to keep all of that logic in the controller, to just deliver to the view an array of ready slides. How can I do something like this (see line 9):

    //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,
                ));
    }

All it gives me at the moment (the contents of $content[$i]['html']) is

{"headers":{}}

解决方案

It's better if you include the template in the template, this way you keep the templating rendering in the view layer and the logic in the controller layer.

But well, if you really want it...

You can use 2 services to do that: twig is using the Twig_Environment or templating.engine.twig which is a templating layer build in Symfony2 for Twig, this can be easily switched ot templating.engine.php.

If you use the twig service, you can see the twig docs on how to use it:

$template = $this->get('twig')->render('/full/path/to/Resources/views/'.$content[$i]['template'].'/view.html.twig', array(...));

If you use the templating.engine.twig service, see the templating docs on how to use it, which is almost exact the same as the Twig_Environment.
