PHP UndefinedIndex while trying to create multiple table rows
The following program calculates some input when given into a form.
The thing i am trying to achieve is that it adds a new table row into the table when i go back to the form to enter new data.I keep getting undefind index and i am not able to get multiple rows in my table. Notice: Undefined index: file name
Notice: Undefined index: size Notice: Undefined index: floor Notice: Undefined index: phone Notice: Undefined index: networkAnd am i adressing the table correctly?
Regards.

When you read from your session you use a lower case t for table.
$ Table = $ _SESSION ['table'];
When you write it back, you use an upper case T for table.
$ _SESSION ['Table'] = $ table;
They are different.
Try using something like print_r($_SESSION); to help you debug this kind of problem...
also..
Your initial if statement might have the logic the wrong way around. should this...
if (empty ($ _POST))
be
if (!empty ($ _POST))
加载中,请稍侯......
