how to maintain session?

[janice]

hi can anybody tel mi how to maintain the session???

coz my session can oni be use once....izit i should register the session in every html????or else how am i suppose to maintain n pass on the session???

At the start of each page where you use session information, insert the line

session_start();

And all your sessioned data can then be accessed/altered via the $_SESSION[] array (from PHP4.1 onwards; $HTTP_SESSION_VARS[] for other versions of PHP4).

[janice]

//start session
session_start( );

	//save data to session
	session_register("sessdata");

	//data to save
	$sessdata = $username;



	if( $row["type"] == "st" )
	{
		header('Location:try.php');
			exit;
	}
	if( $row["type"] == "ag" )
	{
		header('Location:agent.htm');
			exit;

this is the agent.htm session

//start session
session_start();

//save data to session
session_register("store2");

$store2 = $HTTP_SESSION_VARS["sessdata"];

print("$store2");

?>
inside a agent htm there is a link to data.htm

this is data.htm session

//start session
session_start();

$sesssss = $HTTP_SESSION_VARS["sessdata"];

	//save data to session
	session_register("sessdata");

@ $link1 = mysql_connect('localhost','root', '');
if (!$link1) 
{
	print("Error: Could not connect to database. Please try again later.");
	exit;
}

so after i login to agent.htm i can oni click on one option if i wan to click back and chose another option there will be a warning message show:

Failed opening 'c:\inetpub\wwwroot\project\data.php' for inclusion(include_path ='.;c:\php4\pear')in
unknown on line 0

so do u know what go wrong?

Well, for one thing, don't go mixing session_register()ed variables and the session array (in fact, I'd suggest forgetting completely about using session_register() to create variables); just use one or the other - otherwise you'll just get confused and if you get confused when you're writing your program, your program will be confused when it runs.

If you're using $HTTP_SESSION_VARS['sessdata'], then as the manual states, you don't use session_register('sessdata') at all; just use $HTTP_SESSION_VARS['sessdata'] instead of $sessdata. If you're using PHP4.1 or later, $_SESSION['sessdata'] is a more convenient name for your session variable. Either one you use, just use it like any other array.

Your error message doesn't have anything to do with sessions, though; it's saying that PHP couldn't open data.php for some reason (either it's not there, or it doesn't have permission to). Since the code you give doesn't have any include statements in it, I guess that it's from data.php (or data.htm as you call it - are you confused about the file name?). That being the case, it's irrelevant to your immediate problem, since PHP right now can't even load it.

basically how my system work is that it will first go to a login page, from the login page, different pple will access to different first page depending on what position they are( etc, staff or member ).

in my redirection page, i will start the session_start() and store the variable.

lets say if i am a staff, and when i am in the firstpage, i have different links to choose where i want to go to. the problem that i am facing now that i can only view once! after i click back and want to select the same link again, it gives me that BIG ERROR!

does it mean that my session not yet started? or is there any parts of the coding that i missed out?!

[janice]

sorry..i think i type wrongly..is shld be agent.php and data.php...

Failed opening 'c:\inetpub\wwwroot\project\data.php' for inclusion

In other words, PHP couldn't open that file. Are you saying it manages to open it once, but not the second time?

[janice]

in my agent.php page i got 3 links..when i click on the 1st link it will produce mi with data...but after i click back n chose another link it give mi that error message...i am sure that there is no missing file and all my file are there....

ya i manage to open it once but not twice.....

Well lets say you post agent.php here (between [ php ] tags). Abbreviate any pure HTML and **** anything confidential, but leave all the PHP in.

And, please, try and be a bit more careful with your typing; it's very hard to read otherwise...
