READONLY不能在复选框上工作，因为它阻止你编辑字段的值，但有一个复选框，你实际上是编辑字段的状态(| |关闭)

It’s important to understand that READONLY merely prevents the user from changing the value of the field, not from interacting with the field. In checkboxes, for example, you can check them on or off (thus setting the CHECKED state) but you don’t change the value of the field.

如果您不想使用已停用但仍想提交值，如何将值提交为隐藏字段，并在不满足编辑条件时将其内容打印给用户？例如

// user allowed change

if($user_allowed_edit)

{

echo ' Check value';

}

else

{

// Not allowed change - submit value..

echo '';

// .. and show user the value being submitted

echo ' Check value';

}
