如何在symfony2表单中生成多个复选框

Question

我想在Symfony表单中显示预定义数组的复选框.用户应该能够选择多个,但我无法做到.

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)
    ;
}

Answer 1

请参阅choice类型参考.

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

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

Answer 2

您可以改用choice字段：

public function buildForm(FormBuilder $builder, array $options)
{        
    $roles = array("role1","role2","role3");
    $builder
        ->add('name')
        ->add('roles', 'choice', array(
            'choices' => $roles,
            'multiple' => true,
            'expanded' => true,
        ))    
    ;
}
