Symfony手动创建复选框和单选按钮，不使用表单生成器

// 在表单类中定义属性和构造函数
class MyFormType extends AbstractType
{
    private $checkboxOptions;

    public function __construct()
    {
        $this->checkboxOptions = array(
            'option1' => 'Option 1',
            'option2' => 'Option 2',
            'option3' => 'Option 3'
        );
    }

    // 生成复选框的方法
    public function generateCheckbox()
    {
        $builder = new FormBuilder(null, null, new EventDispatcher());

        foreach ($this->checkboxOptions as $value => $label) {
            $builder->add($value, CheckboxType::class, array(
                'label' => $label,
                'required' => false
            ));
        }

        $form = $builder->getForm();

        return $form->createView();
    }

    // 生成单选按钮的方法
    public function generateRadioButton()
    {
        $builder = new FormBuilder(null, null, new EventDispatcher());

        foreach ($this->checkboxOptions as $value => $label) {
            $builder->add($value, RadioType::class, array(
                'label' => $label,
                'required' => false
            ));
        }

        $form = $builder->getForm();

        return $form->createView();
    }
}

// 在控制器或视图中调用生成方法
$formType = new MyFormType();
$checkboxHtml = $formType->generateCheckbox()->createView();
$radiobuttonHtml = $formType->generateRadioButton()->createView();
