枝条自定义文本字段不显示 - 语法错误？

Question

有人在这里熟悉枝条吗？ Wordpress主题Realia应该在价格字段为空时显示自定义文本字段。但事实并非如此。这是我认为应该负责的代码。

<div class="property span9"> 
    <div class="row"> 
     <div class="image span3"> 
      <div class="content"> 
       <a href="{{ wp.get_permalink(property.ID) }}"></a>

        <img src="{{ wp.aq_resize(wp.wp_get_attachment_url(wp.get_post_thumbnail_id(property.ID), 'full'), 270, 200, 'true') }}" alt="{{ property.post_title }}"> 
       {% else %} 
        <img src="{{ wp.get_template_directory_uri() }}/assets/img/property-tmp-small.png" alt="{{ property.post_title }}">

Answer 1

尝试：

{% if property.meta._property_price_suffix == false %} 

在文档的末尾的表在http://twig.sensiolabs.org/doc/tags/if.html是有用的。
