[Phpwebsite-developers] Session Question

[Ken N. <ke...@co...>]

OK...

This may be a phpws programming 101 question, but I think my current
problem lies with not understanding phpws sessions.  For the sake of an
illustration, I am picking the announcement module.

1)  runtime.php is parsed
      a)  it parses Announcement.php
      b)  checks to see if any announcements are in the db
      c)  if there are, it creates a new PHPWS_Announcement for every
announcement, uses the view() method 
      d) then displays the announcement(s)

So far, so good!

Now, I look into announcements' index.php and see (for me) a confusing
array of session names.  I snipped the non-manager $_REQUEST case/switch
items.  If someone will be so kind as to explain the how and why, I
would really appreciate it.

/mod/announce/index.php (lines 90-115)

<snip>

if(isset($_REQUEST["ANN_user_op"]))
switch($_REQUEST["ANN_user_op"]) {
 case "list":
 $_SESSION["SES_ANN_MANAGER"]->listAnnouncements();
 break;

 case "view":
 $_SESSION["SES_ANN"] = new PHPWS_Announcement($_REQUEST["ANN_id"]);
 $_SESSION["SES_ANN"]->view("full");
 $_SESSION["SES_ANN"]->hit();
 break;

 case "submit_announcement":
 $_SESSION["SES_ANN_MANAGER"]->userMenu();
 $_SESSION["SES_ANN"] = new PHPWS_Announcement;
 $_SESSION["SES_ANN"]->edit();
 break;

 case "save":
 $_SESSION["SES_ANN"]->save();
 break;

 case "categories":
 $_SESSION["SES_ANN_MANAGER"]->categories();
 break;
}

</snip>

Specifically:
  case "view" uses all $_SESSION["SES_ANN"] while
  case "submit_announcement" uses both
     $_SESSION["SES_ANN_MANAGER"] and
     $_SESSION["SES_ANN"]

I know this has to be a really obvious methodology, but I think I am
missing the forest because of the trees.  Oh, before I sent this in to
the list, I did RTFD and STFW for some direction.  If someone could walk
me through this on or off list, I would appreciate it.
