问题描述

我还没有找到任何简单的方法来完成默认情况下简单地选中复选框.那不可能那么难，那我错过了什么?

I have not found any easy way to accomplish to simply check a Checkbox by default. That can not be that hard, so what am i missing?

推荐答案

您只需将模型或实体中的值设置为 true，然后将其传递给 FormBuilder，然后就应该对其进行检查.

You would simply set the value in your model or entity to true and than pass it to the FormBuilder then it should be checked.

如果您查看文档中的第一个示例:

If you have a look at the first example in the documentation:

创建一个新任务，然后执行 setTask 并将此任务添加到 FormBuilder.如果你对你的复选框做同样的事情

A new task is created, then setTask is executed and this task is added to the FormBuilder. If you do the same thing with your checkbox

$object->setCheckboxValue(true);

并传递对象，您应该看到复选框被选中.

and pass the object you should see the checkbox checked.

如果它没有按预期工作，请返回一些重现错误的示例代码.

If it's not working as expected, please get back with some sample code reproducing the error.
