OK Folks, I realize that sessions management is 'magic' but I really want to know how it works. First some background
I've got session working with mySQL. I can see the cookie in my browser and it matches up with a record in the sessions table.
My table looks like so:
+-----------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-----------+-------------+------+-----+---------+-------+
| id | varchar(32) | | PRI | | |
| a_session | text | YES | | NULL | |
| givenName | varchar(20) | YES | | NULL | |
+-----------+-------------+------+-----+---------+-------+
I have 2 test files, very simple and straight forward. These work fine.
==================
- IN.html
[-
$req = shift;
$udat{givenName} = "john";
-]
==================
- OUT.html
[-
$req = shift;
-]
[+ $udat{givenName} +]<br>
[+ $udat{_session_id} +]
==================
However if I modify the files as described below, it also works and I don't know why?
NOTE: I haven't modified the table to add an additional field.
==================
- IN.html
[-
$req = shift;
$udat{givenName} = "john";
$udat{surname} = "smith";
-]
==================
- OUT.html
[-
$req = shift;
-]
[+ $udat{givenName} +]<br>
[+ $udat{surName} +]<br>
[+ $udat{_session_id} +]
==================
When I load IN.html and then OUT.html a second time, I get the value for 'surName', but I'm not sure where it's coming from? Can anyone explain?
Thanks.
