Problem with session_start()

[simontheak]

Ok, I'm in the middle of writing my first script using sessions. Here's what I've got so far:

<?php
$user = $_POST['username'];
$pass = $_POST['password']; 


$db = mysql_connect("localhost") or die ("Couldn't connect to database"); 
mysql_select_db("test", $db) or die ("Couldn't select the database."); 
$result = mysql_query("select * from details where username='$user' AND password='$pass'", $db); 

$rowCheck = mysql_num_rows($result);

if($rowCheck > 0){ 
while($row = mysql_fetch_array($result)){ 

  //start the session and register a variable 

  session_start(); 
  
  //successful login code will go here... 
  echo 'Success!'; 

   } 
}

?>

However, when I run the script I get all kinds of error messages like:

Warning: session_start(): open(/tmp\sess_c7f958a2fd528361fe4cbf743be3dc4f, O_RDWR) failed: No such file or directory (2) in c:\apache\apache\htdocs\sessions.php on line 16

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at c:\apache\apache\htdocs\sessions.php:16) in c:\apache\apache\htdocs\sessions.php on line 16

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at c:\apache\apache\htdocs\sessions.php:16) in c:\apache\apache\htdocs\sessions.php on line 16

They all seem to be do with the header information. Can anyone give me any hints on what I might be doing wrong?

Thanks alot

PHP cant access the /tmp directory for some reason, which it need to save the session information. Contact your server administrator.

Hi drzoid - thanks for the reply,

So does that mean that I need to put a tmp directory inside the htdocs directory?

No, its a PHP configuration (respectively directory permission) related matter.
