Question

以下程序在给定表格时计算一些输入我想要实现的是，当我返回表单输入新数据时，它会在表中添加一个新的表行。

我一直得到unfind索引，我无法在我的表中获得多行。注意：未定义的索引：文件名
注意：未定义索引：大小
注意：未定义的索引：floor 注意：未定义的索引：电话
注意：未定义索引：网络

我正在正确地对待桌子吗？

问候。

Answer 1

当您从会话中读取时，您使用小写字母t表。

$ Table = $ _SESSION ['table'];

当你把它写回来时，你使用大写字母T表。

$ _SESSION ['Table'] = $ table;

他们是不同的。

尝试使用类似print_r($_SESSION);的内容来帮助您调试此类问题......

也..

你的初始if语句可能有错误的逻辑方式。应该这样......

if (empty ($ _POST))

是

if (!empty ($ _POST))

尝试创建多个表行时，PHP UndefinedIndex
