如何以symfony2形式生成多个复选框 [英] How to generate multiple check boxes in symfony2 form

问题描述

我想在我的 Symfony 表单中显示预定义数组中的复选框.用户应该可以选择多个，但我无法选择.

I want to display checkboxes from a pre-defined array in my Symfony form. User should be able to select more than one but I am not able to do it.

这是我的代码:

public function buildForm(FormBuilder $builder, array $options)
{
    $roles = array('role1', 'role2', 'role3');
    $builder
        ->add('name')
        ->add('roles', 'checkbox', $roles)
    ;
}

推荐答案

参见 choice 类型引用.

See the choice type reference.

public function buildForm(FormBuilder $builder, array $options)
{
    $roles = ['role1', 'role2', 'role3'];

    $builder
        ->add('name')
        ->add('roles', 'choice', [
            'choices' => $roles,
            'multiple' => true,
            'expanded' => true
        ])
    ;
}
