[RESOLVED] ID in session doesn't get set

[kilbey1]

When I pass data through a post or session, not everything gets passed in all cases (post or session). I am attempting to trace down my error. The flow is edit.php -> process.php calls newsHandler class -> (edit.php or main.php).

When the form on edit.php is processed, I can print out an array, but my form is never update because ID never makes it to the function. (this appears to be a post) When I do a refresh, I lose all array info (this appears to be a session).

On the initial form, I have the following:

if (isset($_SESSION['value_array']['id'])) {
    //print_r($_SESSION['value_array']);
	$id = $_SESSION['value_array']['id'];
} else {
	$id = $_POST['id'];
}

...which is all later unset at the end of the page.

Then, we make the form direct to process.php:

if (preg_match("/status=edit/i", $prevreferer)) {
			$data = $newsHandler->editArticle($id,$postedValue,$displaydate);


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

Within process.php, we make a call to a function editArticle within a class:

	function editArticle($id,$text,$displaydate='') {
		if (isset($_SESSION['value_array']['id'])) {
			$postArray = array(
		   		'id' => $_SESSION['value_array']['id'],
		   		'text' => $_SESSION['value_array']['text'],
		   		'display_date' => $_SESSION['value_array']['displaydate']
		   );
		   $setaction = "session";
		} elseif ( isset( $_POST ) ) {
		   $postArray = &$_POST ;			// 4.1.0 or later, use $_POST
		   $setaction = "post";
		} else {
		   $postArray = &$HTTP_POST_VARS ;	// prior to 4.1.0, use HTTP_POST_VARS
		   $setaction = "http_post_vars";
		}

	//echo $setaction . "<br /><br />";
	//print_r($postArray);

	foreach ( $postArray as $sForm => $value )
	{
		if ( get_magic_quotes_gpc() ) {
			$postedValue = htmlspecialchars( stripslashes( $value ) ) ;
		} else {
			$postedValue = htmlspecialchars( $value ) ;
		}
	}

	//print_r($postedValue);

Can someone set me straight on my use of sessions here?

Where do you start your session?

[kilbey1]

I have a session class that gets included at the start of each page. The constuctor calls session_start(), and then a new instance of the class is instantiated, so that when the class is included on a page, the session is in existence.

I think that ID never makes it to the function because you never set $_SESSION['value']['id'] = $id or any value. You check for to see if it is set, but I don't see you setting it to a value.

Got it! The solution ended up being...

edit.php:

if (isset($_POST['id'])) {
	$id = $_POST['id']; // works
	$_SESSION['value_array']['id'] = $id;
	$text = $newsHandler->displayArticle($id);
	$_SESSION['value_array']['text'] = $text;	
	$displaydate = $_POST['displaydate'];
	$_SESSION['value_array']['displaydate'] = $displaydate;	
} else {
	$id = $_SESSION['value_array']['id'];
	if(!empty($id)) { 
		$oFCKeditor->Value = $newsHandler->displayArticle($id);
	} else {
		$oFCKeditor->Value = '' ;
	}
	$displaydate = $_SESSION['value_array']['displaydate'];
}

With a change in the class...

		if (isset($_SESSION['value_array'])) {
			$_SESSION['value_array']['text'] = $_SESSION['value_array']['FCKeditor1'];			
			$text = $_SESSION['value_array']['text'];
			$id =  $_SESSION['value_array']['id'];
			$displaydate = $_SESSION['value_array']['displaydate'];
			$postArray = array(
		   		'id' => $id,
		   		'text' => $text,
		   		'display_date' => $displaydate
		   );
		} elseif ( isset( $_POST ) ) {
		   $postArray = &$_POST ;			// 4.1.0 or later, use $_POST
		   $id = $_POST['id'];
		   $text = $_POST['text'];					
		} else {
		   $postArray = &$HTTP_POST_VARS ;	// prior to 4.1.0, use HTTP_POST_VARS
		   $id = $HTTP_POST_VARS['id'];
		   $text = $HTTP_POST_VARS['text'];
		}
