我在表单中有一个实体字段(访问者)。我想根据其状态强调一个人。
->add('visitors', 'entity', array(
'class' => "T2m3Bundle:Person",
'multiple' => true,
'property' => 'entireName',
'required' => false,
)
我有一个方法getStatus
,它返回4个状态。在每个州,我都想把不同的风格"在选项标签中。
以下是示例:
<select>
<option value="1">Mary</option>
<option value="2" class="alert alert-danger">John</option>
<option value="3" class="alert alert-success">Peter</option>
<option value="4" class="alert alert-warning">Robert</option>
</select>
所以我想做这样的事情:
{% for visitor in form.visitors %}
{% set index = visitor.vars.value %}
{% set entity = form.visitors.vars.choices[index].data %}
{% if entity.status == 1 %}
{{ form_widget(visitor) }}
<span class="alert alert-warning">{{ entity.entireName }}</span>
{% endif %}
{% if entity.status == 2 %}
{{ form_widget(visitor) }}
<span class="alert alert-danger">{{ entity.entireName }}</span>
{% endif %}
....
{% endfor %}
此示例适用于'expanded' => true
,但不适用于折叠类型。我真的很感谢你的答案。
提前致谢!
修改
扩展使用此模板form_widget(...)
:
{% block choice_widget_expanded -%}
<div {{ block('widget_container_attributes') }}>
{%- for child in form %}
{{- form_widget(child) -}}
{{- form_label(child) -}}
{% endfor -%}
</div>
{% endblock choice_widget_expanded %}
但我不知道如何渲染手动折叠类型,其中没有{{- form_widget(...) -}}
答案 0 :(得分:0)
尝试覆盖树枝选择窗口小部件:请参阅this link以查找相应的块。它是这样的
{% block choice_widget_collapsed -%}
{% if required and placeholder is none and not placeholder_in_choices and not multiple -%}
{% set required = false %}
{%- endif -%}
<select {{ block('widget_attributes') }}{% if multiple %} multiple="multiple"{% endif %}>
{% if placeholder is not none -%}
<option value=""{% if required and value is empty %} selected="selected"{% endif %}>{{ placeholder|trans({}, translation_domain) }}</option>
{%- endif %}
{%- if preferred_choices|length > 0 -%}
{% set options = preferred_choices %}
{{- block('choice_widget_options') -}}
{% if choices|length > 0 and separator is not none -%}
<option disabled="disabled">{{ separator }}</option>
{%- endif %}
{%- endif -%}
{% set options = choices -%}
{{- block('choice_widget_options') -}}
</select>
{%- endblock choice_widget_collapsed %}
{% block choice_widget_options -%}
{% for group_label, choice in options %}
{%- if choice is iterable -%}
<optgroup label="{{ group_label|trans({}, translation_domain) }}">
{% set options = choice %}
{{- block('choice_widget_options') -}}
</optgroup>
{%- else -%}
{# HERE we define the class based on the status #}
{% if status is defined %}
{% if status == 1 %}
{% set status_class = 'alert alert-warning' %}
{% elseif status == 2 %}
{% set status_class = 'alert alert-danger' %}
{% elseif ... %}
....
{% endif %}
{% endif %}
<option value="{{ choice.value }}"{% if choice is selectedchoice(value) %} selected="selected"{% endif %} {% if status_class is defined %} class="{{ status_class }}" {% endif %} >{{ choice.label|trans({}, translation_domain) }}</option>
{%- endif -%}
{% endfor %}
{%- endblock choice_widget_options %}
最后在你的模板中,像这样调用小部件:
{% for visitor in form.visitors %}
{% set index = visitor.vars.value %}
{% set entity = form.visitors.vars.choices[index].data %}
{{ form_widget(visitor, {'status': entity.status}) }}
....
{% endfor %}
这未经过测试,但应该可行。让我知道。
