推荐答案

这是一个蛋糕回退，以防你不选择复选框，为验证跳跃。
在这种情况下php不会提交任何此字段（甚至一个空字符串）。因此蛋糕找到了解决这个问题的聪明的解决方法。

this is a cake fallback in case you don't select the checkbox and post the form in order for the validation to jump in. in this case php would not submit anything for this field (not even an empty string). therefore cake has found a smart workaround to overcome this issue.

类似的东西与单选按钮btw。

similar thing with radio buttons btw.
