Question

当我单击是保存维护值时，如果单击是更改保存到数据库1，而0则为否。

但现在由于某种原因它被卡在1上，并且不会将配置维护行值从1更改为0

Answer 1

我不会肯定地说，但看起来你没有对editSettings函数的函数调用进行任何检查：

if($this->input->server('REQUEST_METHOD') == 'POST')

您应该添加网址变量还是“删除？”复选框以检查以确保将其设置为您要删除某些内容的构造。使用此函数调用，每次提交表单时，无论表单中的任何值如何，都会调用此editSettings函数并删除内容。

更改表单时不更改数据库中的值
