Warning: session_start() [function.session-start]: Node no longer exists in...

[CraigR]

I recently moved hosting provider, and have come across an error which I hadn't previously noticed. (the error doesn't occur on my local server, only my hosting server)


Warning: session_start() [function.session-start (http://www.photostudio.forthwebsolutions.com/function.session-start)]: Node no longer exists in /xxx/galleryoptions.php on line 3


Line 3 on this page is as follows...


if (!session_id()) session_start();


If I comment out line 3, the error disappears

Do either of these links help

are you using PHP5 code on a PHP4 server ?

[CraigR]

Hi Dave, thanks for the feedback.

My hosting server is using php 5.2.12.

I can get rid of the message by commenting out the session_start line, (also suggested in one of the links you provided), but would like to understand why.

[Dave Buchholz]

What's on the first two lines ?

[CraigR]

Here is the php block before the doctype...

<?php require_once('Connections/photostudio.php'); ?>
<?php
//if (!session_id()) session_start();
if(!isset($_SESSION["gallery"])) {
$_SESSION["gallery"] = "grid_fullsize";//default value
}
if((((isset($_POST["gallerytype"]))?$_POST["gallerytype"]:"") != "")) {
$_SESSION["gallery"] = "".((isset($_POST["gallerytype"]))?$_POST["gallerytype"]:"") ."";
}
$gallery =($_SESSION['gallery']);
?>

[Dave Buchholz]

this is the code I use to initialise sessions


/*
Enable Sessions
----------------------------------------------------------
*/

if (!isset($_SESSION)) {
session_start();
}


note the extra braces, try that and see if he makes a difference.

I have never seen this error and as you have no doubt found Google is not much help

[CraigR]

thanks Dave , but no luck yet

I also checked the php.ini on my hosting server to see if session.auto_start was set, but it isn't.

[Dave Buchholz]

sorry, don't know what else to suggest

hopefully Jason will have a bright idea

[CraigR]

he usually does !

just noticed, when the page loads for the first time, all is ok.

use the form in the header to change the look, the page reloads.

on the second reload, the error occurs.

I dont have any bright ideas on the cause of the problem, sorry guys.

to make the error go away, and still start the session, change:

if (!session_id()) session_start();


to:

@session_start();


This will run the session_start() function and suppress any errors that may occur.

[CraigR]

Thanks Jason.

That at least hides the problem.
