根据项目覆盖表单呈现模板 [英] Overriding the form rendering template according to the items

问题描述

例如
我在表单对象中有两个成员.

For example
I have two members in form object.

form_widget(form.icon)

form_widget(form.icon)

form_widget(form.name)

form_widget(form.name)

我更改了"choice_widget_expanded"

I have changed 'choice_widget_expanded'

{% block choice_widget_expanded %}
{% spaceless %}
    <table {{ block('widget_container_attributes') }}>
    {% for child in form %}
      <tr>
        {{ form_widget(child) }}
        {{ form_label(child) }}
      </tr>
    {% endfor %}
    </table>
{% endspaceless %}
{% endblock choice_widget_expanded %}

但是我只想让它影响{{form.icon}}

However I would like to make it affect on {{form.icon}} only

有可能吗?我怎么知道传递给该块的对象是form.icon或form.name?

is it possible ? how can I tell the object passed to this block is form.icon or form.name?

推荐答案

要覆盖choice_widget_expanded的标签块，您可以定义块并按以下方式使用它

To override label block for choice_widget_expanded you can define your block and use it like in below

{% block choice_widget_expanded %}
{% spaceless %}
    <table {{ block('widget_container_attributes') }}>
    {% for child in form %}
      <tr>
        {{ form_widget(child) }}
        {{ form_label_custom(child) }}
      </tr>
    {% endfor %}
    </table>
{% endspaceless %}
{% endblock choice_widget_expanded %}

对于自定义标签也是如此form_label_custom

And for the custom label too form_label_custom

现在请注意具有扩展属性(并非全部)的每个选择字段 字段)，您的新标签将会生效

Note now for every choice field with expanded property (not all fields) your new label will be in action

{% block form_label_custom %}
{% spaceless %}
    {% if label is not sameas(false) %}
        {% if not compound %}
            {% set label_attr = label_attr|merge({'for': id}) %} /* you can skip this part for td */
        {% endif %}
        {% if required %}
            {% set label_attr = label_attr|merge({'class': (label_attr.class|default('') ~ ' required')|trim}) %}
        {% endif %}
        {% if label is empty %}
            {% set label = name|humanize %}
        {% endif %}
        <td {% for attrname, attrvalue in label_attr %} {{ attrname }}="{{ attrvalue }}"{% endfor %}>{{ label|trans({}, translation_domain) }}</td>
    {% endif %}
{% endspaceless %}
{% endblock form_label_custom %}

甚至更多，您可以定义自定义form_widget_custom(child)块以覆盖

Or even more you can define the custom form_widget_custom(child) block to override like

{% block form_widget_custom %}
{% spaceless %}
    {% if compound %}
        {{ block('form_widget_compound') }}
    {% else %}
        {{ block('form_widget_simple') }}
    {% endif %}
{% endspaceless %}
{% endblock form_widget_custom %}

现在渲染您的字段

{{ form_widget_custom(form.icon) }}
