[RESOLVED] Session only carries once through form

[kilbey1]

I'm having some trouble with my sessions only working once through a form. Any tips on what I may be missing?

edit.php: The form initially sets up the ID of the item in question.

		//get the article to edit
		if (isset($_POST) && !empty($_POST)) {
			$id = $_POST['id'];
		} elseif (isset($_SESSION)) {
			$id = $_SESSION['id'];
		}

Upon first submission of the form, process.php handles the processing behind the scenes, and returns it to the referring page.

if (preg_match("/status=edit/i", $prevreferer)) {
	  //	if (isset($_POST['id'])) {
	//		$id = $_POST['id'];
	//	} elseif (isset($_SESSION)) {
	//		$id = $_SESSION['id'];
	//	}
		$id = $_SESSION['id'];
		print_r($_SESSION);
		print_r($_POST);


		$data = $newsHandler->editArticle($id,$postedValue,$displaydate);

		if($data == false) {
			//$_SESSION['id'] = $id;
			$_SESSION['value_array'] = $_POST;
    		$_SESSION['error_array'] = $newsHandler->error;
	  	    //header("Location: ".$session->referrer."");
			//flush();
			exit;
		} else {
		$_SESSION['value_array'] = $_POST;
    		$_SESSION['error_array'] = $newsHandler->error;
	  	    header("Location: http://localhost/steelfacts/admin/main.php");
			//flush();
			exit;
		}

We return to the referring page (edit.php), and it displays the new changes. On a second submit, however, despite the ID existing, no changes ever show up.

Have you added session_start(); before any output any script that using $_SESSION variable?

Thanks; I think it was a comment I had put previous to the session output start. (Either that, or logging out and back in fixed it)
