树枝和自蔓延 [英] Twig and autoescaping

问题描述

我正在学习Symfony2。目前，我试图在树枝模板中呈现表单标签。该标签包含一个html标签，在我的枝条文件中没有正确显示。

下面是创建表单字段的代码片段：

  $ builder-> add（'zipcode'，'integer'，array（
'label'=>'< abbr title =Zone Improvement Plan> CAP< / abbr> code'，
））; 
  

在twig文件中，我渲染字段标签如下：

  {{form_label（form.zipcode）}} 
  

$ b $我尝试过raw，escape，e过滤器，但html页面中提供的结果始终是字符串

  < abbr title =区域改进计划> CAP< / abbr>代码
  

而不是相应的HTML代码！

<任何建议？
提前感谢！

稍后我找到了解决方案。
解决方案是禁用Symfony提供的标签块中的自动版本路径：
symfony / src / Symfony / Bridge / Twig / Resources / views / Form / form_div_layout.html.twig

所以，在你的twig文件中，你必须将以下行放在窗体之外：
{％form_theme form _self％}

  {％block generic_label％} 
 {％spaceless％} 
 {％如果需要％} 
 {％set attr = attr | merge （{'class'：attr.class | default（''）〜'required'}）％} 
 {％endif％} 
< label {％for attrname，attrvalue in attr％} { {attrname}} ={{attrvalue}}{％endfor％}> {％autoescape false％} {{label | trans}} {％endautoescape％}< / label> 
 {％endspaceless％} 
 {％endblock％} 
  

解决方案

从 JeanValjean 自己：

  {％autoescape false％} {{form.zipcode.vars.label | trans}} {％endautoescape％} 
  

为了将此行为推广到整个应用程序，您可以覆盖标签的表单块：

  {％block generic_label％} 
 {％spaceless％} 
 { ％如果需要％} 
 {％set attr = attr | merge（{'class'：attr.class | default（''）〜'required'}）％} 
 {％endif％} 
< label {％for attrname，attrvalue in attr％} {{attrname}} ={{attrvalue}}{％endfor％}> 
 {％autoescape false％} {{label | trans}} {％endautoescape％} 
< / label> 
 {％endspaceless％} 
 {％endblock％} 
  

I'm learning Symfony2. Currently, I'm trying to render a form label in a twig template. The label includes an html tag, that is not rendered correctly in my twig file.

Here follows the piece of code where the form field is created:

$builder->add('zipcode', 'integer', array(
        'label' => '<abbr title="Zone Improvement Plan">CAP</abbr> code',
        ));

In the twig file I render the field label as follows:

{{ form_label(form.zipcode) }}

I tried the raw, escape, e filters, but the results provided in my html page is always the string

 <abbr title="Zone Improvement Plan">CAP</abbr> code

and not the corresponding HTML code!

Any suggestion? Thanks in advance!

Later I found the solution. The solution is to disable the autoescape within the label block provided by Symfony at path: symfony / src / Symfony / Bridge / Twig / Resources / views / Form / form_div_layout.html.twig

So, in your twig file you have to put the following lines outside the form: {% form_theme form _self %}

{% block generic_label %}
{% spaceless %}
  {% if required %}
      {% set attr = attr|merge({'class': attr.class|default('') ~ ' required'}) %}
  {% endif %}
  <label{% for attrname,attrvalue in attr %} {{attrname}}="{{attrvalue}}"{% endfor %}>{% autoescape false %}{{ label|trans }}{% endautoescape %}</label>
{% endspaceless %}
{% endblock %}

解决方案

From JeanValjean himself :

{% autoescape false %}{{ form.zipcode.vars.label | trans }}{% endautoescape %}

And to generalize this behaviour to your whole app, you can override the form block for labels :

{% block generic_label %}
    {% spaceless %}
        {% if required %}
            {% set attr = attr|merge({'class': attr.class|default('') ~ ' required'}) %}
        {% endif %}
        <label{% for attrname,attrvalue in attr %} {{attrname}}="{{attrvalue}}"{% endfor %}>
            {% autoescape false %}{{ label|trans }}{% endautoescape %}
        </label>
    {% endspaceless %}
{% endblock %}
