我在网站上使用.twig模板但是我需要对几个视图中的逻辑非常狡猾.我不认为twig可以处理这个问题,而且它可以用 PHP做一块蛋糕. (我不打算解释那是什么的细节,只是在PHP中知道它的简单,我实际上已经有了代码).问题是,我可以在.twig类型的基本模板或父模板中包含.PHP模板吗？

下面的示例(不起作用) – blah.htML.PHP是一个扩展base.html.twig模板的模板…

/some/web/directory/bundlename/Resources/views/blah/blah.html.PHP

<?PHP $view->extend('::base.html.twig') ?>

<?PHP $view['slots']->set('tITle','Welcome to Nowhere!') ?>

<?PHP $view['slots']->start('body') ?>

    <div id="body">
        html stuff here,blah blah blah...
        <?PHP .... ?>
            complex PHP and html stuff,and so on...
        </PHP end....?> 
        you get the idea...
    </div>

<?PHP $view['slots']->stop() ?>

在浏览器上,上面的代码将基本模板中的所有.twig代码呈现为浏览器中的文本(I.E.它不会被模板引擎执行).

PS – 是的,我在app / config / config.yml中设置了.twig和.PHP

templating:      { engines: ['twig','PHP'] }

好的,这里有“复杂”的东西……
这是从在Symfony 1.4中编码的站点版本中获取的 – 它被升级到Symfony 2并且我们想要使用所有.twig

<?PHP foreach ($all_items as $item): ?>
<tr>
    <td valign="top">
        //<?PHP include_partial('global/item',array('item' => $item)) ?>

 <<< some code snipPEd out here >>>

    <td valign="top">
        <table border="1" width="100%">
        <?PHP echo $form->renderFormtag('memberitems/additem') ?>
        <?PHP echo $form['item_id']->render(array('value' => $item->getIid())) ?>
        <?PHP echo $form['user_id']->render(array('value' => 1)) ?>
