Hi all:
It appears that sessions are not available for date time objects pre php 5.3.
Warning: date_format() [function.date-format]: The DateTime object has not been correctly initialized by its constructor
Is there a standard work around for this or do I need to pass a querystring (hope not!):mad:?
I'm assuming you do not actually try to store a datetime object as session data. Have you made certain that you user serialize when you store session data and unserialize when you retrieve session data?

I didn't even know about serialize/unserialize! But I added those functions and now get:
Fatal error: Can't use function return value in write context in
No luck on this at all.
When I place the following on the page where I am initializing the session ti works fine:
echo date_format($_SESSION["eventDate"],"m/d/Y");
When I place it on a separate page I get the following:
Warning: date_format() [function.date-format]: The DateTime object has not been correctly initialized by its constructor in C:\Web\MySite\adm\adm_moSubmit_.php on line 87
Both the initial page and display page both have session_start about the HTML.
Any help appreciated!
Why is this code not working?
echo $stuff;
Well, pretty hard to know. Maybe $stuff hasn't been defined. Maybe I have a parse error on the line before it. Maybe... I should post an error message with my code, and maybe I should post the code I need help with instead of one single line and maybe I also should explain what isn't working. All of these really are needed to get help.

Maybe you should post some code with your error message
Where's your serialize?
Where's your unserialize?
Here is more info:
This is taken from the page that is setting the session:
$_SESSION["l_id"] = $_POST["l_id"];
$paramsListing = array($_SESSION["l_id"]);
$sqlListing = "SELECT Player, Promoter, EventDate FROM Events WHERE l_id = ?";
$stmtListing = sqlsrv_query($conn, $sqlListing, $paramsListing);
$resultListing = sqlsrv_fetch_array($stmtListing);
$_SESSION["player"] = $resultListing["Player"]; $_SESSION["promoter"] = $resultListing["Promoter"];
$_SESSION["eventDate"] = $resultListing["EventDate"];
On the display page is:
echo date_format($_SESSION["eventDate"],"m/d/Y");
As for serialize/unserialize I am not quite sure why they are needed. I am using procedural coding. $SESSION["player"] & $SESSION["promoter"] are both working fine without serializing.
Because player is a string, while datetime isn't. Serializing a datetime object turns it into a string, which can be turned into a datetime object using unserialize.

Still not getting this one to work. This is on the display page:
$rEventDate = serialize($_SESSION["eventDate"]);
echo $rEventDate;
The display is "O:8:"DateTime":0:{}"
The session is good because when I echo the session on the page where I am setting the session , the proper date appears.
# SESSION: initializing, updating etc
if (!isset($_SESSION['datetime']) && isset($datetime))
{
$_SESSION['datetime'] = serialize($datetime);
}
# on every page that needs the datetime
if (isset($_SESSION['datetime']))
{
$datetime = unserialize($_SESSION['datetime']);
}
echo $datetime->format('Y-m-d');
Thanks you again! Now it seems so easy!
