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.
