can't count using session

llhaskovec

Please tell me what is wrong with this example taken from a book? When I run the browser for the code below the count shown is 1, 3, 5 ....... What's up with this? Please be kind, I'm a really really newbie! Using version 4.3.1.

<?
session_start();
session_register('count');
$SESSION[count]++;
$msg = "<P>You've been here $SESSION[count] times. </p>";
?>
<HTML>
<HEAD>
<TITLE>Count Me!</TITLE>
</HEAD>
<BODY>
<? echo "$msg"; ?>
</BODY>
</HTML>

the code might not be functioning because you havent set a default value such as 1

try something like this

<? 
session_start(); 
if ($_SESSION['count']=='') { 
	$_SESSION['count']="1";
}
else {
	 $_SESSION['count']++;
}
$msg = "<P>You've been here ".$_SESSION['count']." times. </p>"; 
?> 
<HTML> 
<HEAD> 
<TITLE>Count Me!</TITLE> 
</HEAD> 
<BODY> 
<?=$msg?> 
</BODY> 
</HTML>

Thanks for you response Tuff, but same problem with code you suggested. Any other suggestions? What could this be?

stolzyboy

the code that tuf supplied works just fine, i tested it, maybe change this line

<?=$msg?>

to this

<? echo $msg; ?>

No, I think I've been misunderstood. I don't doubt that the code works that was previously sent -- it's that it doesn't work on my laptop. Does anyone have any idea why I can't count? Is there possibly something wrong with my set up?

stolzyboy

are you getting error message, what do you see, etc...

llhaskovec

I get no error messages. When I open the page with the browser I see a message like: You've been here 1 time. When I refresh the page I get: You've been here 3 times. Refresh again: You've been here 5 times...............

Thank you for taking the time to try and help me.

is this live anywhere where we can see, what browser are you using, try using a different one, etc...

llhaskovec

I don't have a live version to share. I'm running Apache and using as "localhost". I'm using IE 6.0. I'm trying to get this to some web space to see if it's just me. Thanks. Will response when I get this done.

Thanks again.

stolzyboy

I didn't paste the exact code. Counter error caused by Background="?" in the HTML Body tag. I'm using TextPad editor, it inserts extra attributes if you use "Blank Page".
Thanks to all who tried to help me. This is really a great board.
