#``filter`` Filter sections allow you to apply regular Twig filters on a block of template data. Just wrap the code in the special ``filter`` section: {% filter upper %} This text becomes uppercase {% endfilter %} 还可以链接多个过滤器： {% filter lower|escape %} <strong>SOME TEXT</strong> {% endfilter %} {# outputs "&lt;strong&gt;some text&lt;/strong&gt;" #}
