Symfony2 formbuilder - 实体只读字段作为标签 [英] Symfony2 formbuilder - entity readonly field as label

问题描述

symfony2 是否有可能将实体的只读字段显示为标签而不是文本字段或其他任何内容?

Is there any possibility in symfony2 to display a readonly-field of an entity as a label rather than a text field or whatever?

我目前正在使用以下代码，但使用禁用的文本字段感觉不是很复杂:

I am currently using the following code, but using a disabled text field does not feel very sophisticated:

public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('readonlyfield', 'text', array('property_path' => 'readonlyfield.displayString','disabled' => true));
        $builder->add('editablefield', 'textarea');
    }

我使用的是 symfony 2.4.4..

I am using symfony 2.4.4..

我在另一个表单中使用此表单类型:

I am using this form type from within another form:

public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('mySubEntities', 'collection', array('type' => new MySubEntryType()));
        $builder->add('save_to_db',  'submit', array('label' => 'Submit'));
    }

树枝文件:

 {{ form_start(form) }}
    {% for row in form.mySubEntities %}
        <li>
        <ul>
        <table>
        <tr><td>{{ form_label(row.readonlyfield) }} </td><td>{{ form_widget(row.readonlyfield) }}</td></tr>     
        <tr><td>{{ form_label(row.editablefield) }}</td><td> {{ form_widget(row.editablefield) }}</td></tr>
        </table>
        </ul>
    </li>
    {% endfor %}


{{ form_end(form) }}

推荐答案

您可以使用 {{ form.vars.value.yourfield }} 访问表单中的值.

You can access value in form using {{ form.vars.value.yourfield }}.

你有一个嵌套/集合所以使用 {{ row.vars.value.yourfield }}

You have a nested/collection so use {{ row.vars.value.yourfield }}
