Session troubles

[Arc]

Hi, i have a problem with starting a session on this one page. All the other pages work just fine but when i call this page i get this error.

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /blah/getpassword2.php:2) in /blah/getpassword2.php on line 4

and this is the code on the page.

<?php
If ($Submit){
session_start();
//Check Log In Info
$Sql = "SELECT OnlineID,Password FROM tblSignUp WHERE Email Like '$txtEmailAddress'";
$Result = mysql_query($Sql, $Connect);
If (mysql_num_rows($Result) > 0) {
$resultArray=@mysql_fetch_array($Result);
$OnlineID=$resultArray[0];
$Password=$resultArray[1];
$To = $txtEmailAddress;
$Subject = "Your Account Information from blah.com";
$Body = "<b>Your Account Information from blah.Com<br></b>";
$Body .= "<b>Your OnlineID is: </b>".$OnlineID."<br>";
$Body .= "<b>Your Password is: </b>".$Password."";
mail($To,$Subject,$Body,"From: [email][e-mail][/email]\r\nContent-Type: text/html; charset=iso-8859-1\n");
Print "Your Account Information has been sent.";
}
else {
Print "The email address you entered could not be found in our database.";
}
}
?>

I can not figure out why it is saying it cant start the session becasue this page has already started the session... that makes no sense. I use session start on every other page and i dont get this error.

Any ideas? Thanks!

session_start needs to be on top of the page... as you've done.
Do you have any html output before you php-code?

it looks like your seesion has already beed started, else where. all you need to do use the session_register(), rather than starting it again.

There is no HTML before the session start as you can see from the code.

Jake, you have to put session_start(); on every page that uses a session, not just on the first page... also the session has already been registered in the log in page.

Thanks!

well... this is extremely odd. I added a Print "<br>"; right after the session_start(); and i quit getting the error.😕 It makes no sense at all... anyone have a clue why this would do this?

[kristianblom]

hehehe...
I'm tempted to ask why you added the print "<br>"; ...

it sounds weird

well, on the page there is no html, only php code. I was looking at all the other pages that have session_start(); on them and they all have some HTML. So just out of desperation i added some html to this page and it quit giving the error... I dont understand it.

I though you might have had some code ahead of what you have displayed, starting the session off, hense the error:

headers already sent (output started at /blah/getpassword2.php:2) in /blah/getpassword2.php on line 4

what variables have you register in the session store?
