Symfony2表单标签中的HTML而不是纯文本 [英] HTML in Symfony2 form labels instead of plain text

问题描述

我正在尝试实现类似这样的东西:

I am trying to implement something like this:

<div>
    <input type="checkbox" name="checkbox" id="checkbox_id" />
    <label for="checkbox_id">I agree to the <a href="/tos">Terms of Service</a></label>
</div>

最接近实现此目标的方法是:

The closest I've come to implement this is through:

<div>
    {{ form_widget(form.agreeWithTos) }}
    <label for="{{ form.agreeWithTos.vars.id }}">I agree to the <a href="#">Terms of Service</a></label>
</div>

有更好的方法吗?不必指定{{form.agreeWithTos.vars.id}}. :)

Is there a better way? Having to specify {{ form.agreeWithTos.vars.id }} is inelegant. :)

推荐答案

在我的表单主题中使用以下代码解决了该问题:

Solved this problem using the following code in my form-theme:

{# ---- form-theme.html.twig #}
{% block checkbox_row %}
{% spaceless %}
<div>
    {{ form_errors(form) }}

    <label class="checkbox" for="{{ form.vars.id }}">
        {{ form_widget(form) }}
        {{ label|default(form_label(form)) | raw }}
    </label>
</div>
{% endspaceless %}
{% endblock %}

然后在表单模板中使用:

in your Form-Template you can then use:

{% form_theme form '::form-theme.html.twig' %}

{{form_row(form.termsOfServiceAccepted, {
        'label' : 'I have read and agree to the <a href="#">Terms and conditions</a>'
    })
}}

这样，表单主题中的块将应用于页面上的任何复选框.如果还需要使用默认主题，则可以添加参数以启用特殊渲染:

this way, the block from the form-theme would apply to any checkbox on the page. If you need to also use the default-theme, you can add a parameter to enable special-rendering:

{# ---- form-theme.html.twig #}
{% block checkbox_row %}
{% spaceless %}
    {% if not useTosStyle %}
        {{ parent() }}
    {% else %}
        {# ... special rendering ... #}
    {% endif %}
{% endspaceless %}
{% endblock %}

将被这样使用:

{% form_theme form '::form-theme.html.twig' %}

{{form_row(form.termsOfServiceAccepted, {
        'useTosStyle' : true,
        'label' : 'I have read and agree to the <a href="#">Terms and conditions</a>'
    })
}}
