<p>几乎在每一个树枝上面函数,最后一个参数是一个数组时使用的“变量”的呈现形式的一部分。例如,下面会呈现“部件”字段,并修改其属性包含一个特殊的类:</p> <div translate="no" data-loc="2" class="notranslate codeblock codeblock-length-sm codeblock-jinja codeblock-twig"> <div class="codeblock-scroll"> <pre class="codeblock-lines">1 2</pre> <pre class="codeblock-code"><code><span class="hljs-comment">{#呈现一个小部件,但添加一个“foo”类#}</span><span class="xml"></span><span class="hljs-template-variable">{{form_widget (form.name {attr”:{“类”:“foo”}})}}</span></code></pre> </div> </div> <p>这些变量的目的——他们所做的事情和他们从何而来——可能并不清楚,但是他们非常强大。当你渲染任何形式的一部分,呈现它的块利用大量的变量。生活在默认情况下,这些块<a
