获取symfony中复选框的值 [英] get value of checkbox in symfony

问题描述

我想获取复选框的值(选中与否)，但复选框未添加到表单类型中.这是一个例子

I want to get the value of checkbox (checked or not), but the checkedbox not added to the form type. this is an example

<input type="checkbox" class="checkbox" id="smsflash">

请问是否有可能获取控制器中复选框的值，以及如何获取?

推荐答案

现在可能有点晚了，但我的经验可能与您的问题有关，或者可以帮助其他有类似问题的人.

It may be a bit late now, but my experience may relate to your issue, or may help someone else with a similar issue.

在我的例子中，复选框被添加到 FormType 中，但如果添加到 FormType 之外，将会呈现我想象的相同.

In my case, the checkbox is added to the FormType, but would present the same I imagine if added outside of the FormType.

我使用表单来处理 REST API 请求，复选框是字段之一.提交表单时，标题包含 'Content-Type': 'application/x-www-form-urlencoded' 所以我可以用 Symfony 表单处理它.

I'm using the form to handle a REST API request, and the checkbox is one of the fields. When the form is submitted, the header includes 'Content-Type': 'application/x-www-form-urlencoded' so I can handle it with a Symfony form.

这个问题是表单值作为字符串提交(包括复选框值).在 Symfony 方面，它期望如果 checkbox 属性存在 - 它是一个真实"值，如果它不存在，则复选框为 false.但是，因为复选框值可以通过 API 表单作为字符串false"提交 - 这等同于 true - 所以无论是否选中复选框，该值始终为 true.

The issue with this is the form values are submitted as strings (including checkbox values). On the Symfony side, it expects that if the checkbox property exists - it's a 'truthy' value, if it doesn't exist, the checkbox is false. However because the checkbox value can be submitted as the string "false" through the API form - this equates to true - so the value is always true no matter if the checkbox is checked or not.

处理此问题的一种方法(但可能会限制 FormType 的重复使用)是在表单生成器中将复选框类型从复选框"更改为文本":

One way to handle this (but may limit re-use of the FormType) is to change the checkbox type from 'checkbox' to 'text' in the Form Builder:

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('my_checkbox', 'text', array('error_bubbling' => true,'required' => false))
        ...

然后处理表单(并获取 Checkbox 值)

Then processing the form (and getting the Checkbox value)

$form = $this->createForm(new MyFormType(), $myObject);
$form->handleRequest($request);

if($form->isValid()) {
    $data = $form->getData();
    if($data->getMyCheckbox() === "false") {
        $myObject->setMyCheckbox(false);
    } else {
        $myObject->setMyCheckbox(true);
    }
    ...
