如何在 Symfony 表单选择框中设置所选选项 [英] how to set the selected option in Symfony forms select box

问题描述

我有一个用 Symfony 表单创建的表单.

I have a form created with Symfony forms.

并且在模板中我有这个选择框，使用渲染方法显示在页面上.

and in the template i have this selectbox, displayed on the page with the render method.

<?php echo $form['field']->render() ?>

是否可以设置这个选择框的选中选项?

is it possible to set the selected option of this select box?

或者这是否必须在创建此表单的类中完成?有字段的创建完成:

Or does this have to be done in the class that creates this form? There is the creation of the field done:

public function configure() {
    $this->widgetSchema['field'] = new sfWidgetFormSelect(
      array("choices" => 
          array('1' => 'test1','2' => 'test2')
      )
    );
  }

推荐答案

是的，当然——你应该设置相应的表单值——要么通过 bind()，要么通过小部件的 default 选项.

yes, sure — you should have set corresponding form value — either via bind(), either via widget's default option.

例如，

public function configure() 
{
    $this->widgetSchema['field'] = new sfWidgetFormSelect(array(
        "choices" => array('1' => 'test1','2' => 'test2'), 
        'default' => 2));
}
