PHP & MySQL - CCS v1
Hi,
how many session parameters can be available at any one time?
My reason for asking is that I only seem able to retrieve the last one set !
In page 1, I have this code -
function user_AfterInsert() { //user_AfterInsert @2-AD8D0A3D
//Custom Code @54-2A29BDB7
// -------------------------
//set a session variable to contain the value of autoincrement key for user record
$newone = mysql_insert_id();
CCSetSession($NewUserId, $newone);
// -------------------------
//End Custom Code
} //Close user_AfterInsert @2-FCB6E20C
In Page 2, called from Page 1, I have a field called "UserID", whose default value is - CCGetSession($NewUserId)
It works fine.
In page 2, I have similar code in the After Insert event to set a session parameter called $NewAdId.
In Page 3, called from Page 2 , I have two fields on a form that default to the above two session parameters, just in the same way that the field on Page 2 defaults.
But this time, both fields have the value of the second session parameter set - $NewAdId.
If I remove the default value for the field that should be set to $NewAdId, the other field, which should contain the value for $NewUserId, doesn't - it still defaults to the value for $NewAdId....
As far as I can see, the first session parameter is being over-written by the setting of the second !
Any ideas - this is driving me crazy !!
Thanks,
Mark

They syntax for using CCSetSession is:
CCSetSession(<variable name>, <value>)
You give *name* of the variable (as string), not variable itself. You should use:
$newone = mysql_insert_id();
CCSetSession("NewUserId", $newone);
The described behavior happens because both your variables have empty values and you set and retrieve session variable with empty name.

Hi Chris,
tried it & it doesn't work - I don't even pick up the first variable on Page 2 any more...
I've also tried changing the common.php file as per another thread, by removing the curly braces & extra $ sign from param_name on the two lines marked ** -
function CCSetSession($param_name, $param_value)
{
global ${$param_name}; **
if(session_is_registered($param_name))
session_unregister($param_name);
${$param_name} = $param_value; **
session_register($param_name);
}
But this makes no difference.
In fact if I go back to using CCSetSession($NewUserId ...) and make the above change to common.php, then it doesn't work then either.
Any ideas ?
Thanks,
Mark

Check you have register_globals setting turned on (it is off by default in the latest PHP releases). Or use $HTTP_SESSION_VARS array alternatively:
to set session variable:
$HTTP_SESSION_VARS["variable"]=<value>;
to get session variable:
$value=$HTTP_SESSION_VARS["variable"];
PHP session handling will be fixed in next CCS release.
