Question

我有一个带有一个可选字段（备注）的表单。默认情况下，所有都是必填字段我想让'remark'字段可选。我尝试了很多解决方案。似乎没有人工作。如何使其成为可选项？

这是我的代码

RequestItem.php

/**
 * RequestItem
 *
 * @ORM\Table(name="request_item")
 * @ORM\Entity(repositoryClass="InventoryBundle\Repository\RequestItemRepository")
 */
class RequestItem
{
  /**
     * @var string
     *
     * @ORM\Column(name="remark", type="text", nullable=true)
     */
    private $remark;

RequestItemType.php

class RequestItemType extends AbstractType
{
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('item', EntityType::class, array(
              'class' => 'InventoryBundle:Item',
              'choice_label' => 'name',
              'expanded' => false,
              'multiple' => false,
            ),
              array('attr' =>array('class' =>'form-control', 'style' =>'margin-bottom:15px; width:100px')))
            ->add('date', DateType::class, array('attr' =>array('class' =>'form-control', 'style' =>'margin-bottom:15px')))
            ->add('quantity', TextType::class,array('attr' =>array('class' =>'form-control', 'style' =>'margin-bottom:15px; width:75px')))
            ->add('client', TextType::class,array('attr' =>array('class' =>'form-control', 'style' =>'margin-bottom:15px; width:200px')))
            ->add('remark', TextareaType::class, array('attr' =>array('class' =>'form-control', 'style' =>'margin-bottom:15px', 'required' => false), 'empty_data'  => null))
        ;
    }

我把'required'=＆gt;对于评论领域是假的。

new.html.twig

{% extends 'base.html.twig' %}

{% form_theme form _self %}

{% use 'form_div_layout.html.twig' with form_label as base_form_label %}
{% block form_label %}
  {{ block('base_form_label') }}
    {% if required %}
      <span class="required" title="This field is required" style="color:red">*</span>
    {% endif %}
{% endblock %}

{% block body %}
    <h1>Request Item creation</h1>
    {% if is_granted("ROLE_SUPER_ADMIN") %}

    {% if app.session.flashBag.has('warning') %}
        <div class="alert alert-danger" role="alert">
            {% for msg in app.session.flashBag.get('warning') %}
                {{ msg }}
            {% endfor %}
        </div>
    {% endif %}

    {{ form_start(form) }}
        {{ form_widget(form) }}
        {{ form_row(form.remark, {'required': false}) }}
        <input type="submit" value="Create" class="btn btn-primary" />
    {{ form_end(form) }}

    <hr />
    <a href="{{ path('requestitem_index') }}" class="btn btn-success">Back to the list</a>
    {% else %}
        <h4>Please <a href="{{ path('fos_user_security_login') }}" class="btn btn-default">login</a></h4>
    {% endif %}
{% endblock %}

我在twig文件中添加{{form_row（form.remark，{'required'：false}）}}。

备注字段的页面源视图

<div>  <label for="request_item_remark" class="required">Remark</label>
          <span class="required" title="This field is required" style="color:red">*</span>
    <textarea id="request_item_remark" name="request_item[remark]" required="required" class="form-control" style="margin-bottom:15px" ></textarea></div>

textarea字段是必需的。

我还尝试添加new.html.twig文件

{% extends 'base.html.twig' %}

{% form_theme form _self %}

{% block textarea_widget %}
  <div class="textarea_widget">
    {% set required=required|default('not required') %}
    {{ block('form_widget_simple') }}
  </div>
{% endblock %}

奇怪的是，textarea字段成为输入文本字段，仍然需要它。

<div>  <label for="request_item_remark" class="required">Remark</label>
          <span class="required" title="This field is required" style="color:red">*</span>
      <div class="textarea_widget">
        <input type="text" id="request_item_remark" name="request_item[remark]" required="required" class="form-control" style="margin-bottom:15px"  />
  </div>

表格结构

CREATE TABLE `request_item` (
  `id` int(11) NOT NULL,
  `item_id` int(11) DEFAULT NULL,
  `date` date NOT NULL,
  `quantity` int(11) NOT NULL,
  `client` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
  `remark` longtext COLLATE utf8_unicode_ci
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

不要将required放在attr中，它应该位于选项的顶层。

...
 ->add('remark', TextareaType::class, array('required' => false, 'attr' =>array('class' =>'form-control', 'style' =>'margin-bottom:15px'), 'empty_data'  => null))
...

否则，如果您通过属性设置了此元素，并且required选项没有意义。
