SESSION help

sstonge

When I try to creat a sesion I get a ton of error messages...

here is the php code I am using:

$UserInfo[0] = "Steve";
session_start();
$_SESSION['User_ID'] = $UserInfo[0];

and the errors it shows when I load the page:

Warning: session_start(): open(/tmp\sess_6beabf45fb956f1c53a69b92ec0629c3, O_RDWR) failed: No such file or directory (2) in c:\file.php

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at c:\file.php:8) in c:\file.php

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at c:\file.php:8) in c:\file.php on line 10

Warning: Unknown(): open(/tmp\sess_6beabf45fb956f1c53a69b92ec0629c3, O_RDWR) failed: No such file or directory (2) in Unknown on line 0

Warning: Unknown(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0

Ok I changed the session.save_path in php.ini and now I get only 2 errors... I'm 1/2 way there!!

any sugestions?

here are the 2 errors I still get.

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at file.php:8) in file.php on line 10

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at file.php:8) in file.php on line 10

From the error messages, it seems you are outputing information to the browser before you attempt to redirect the user to another page.

Can you list the complete code here in the browers as I don't believe those 3 lines are causing the problem right off the bat.

Yup, cleric has you on the right path here. Also, ANY whitespace before the session initialization f's it up too... so,

<?php

session_start();

would give you errors.

I got it working, it was because I had some HTML code above the PHP

Try using some output buffering. 🙂 Search up ob_start() and ob_end_flush(). It will allow you to use setcookie(), header(), etc. without getting the error message "Headers already sent.". DevShed have a good article on it. http://www.devshed.com/

If you mean:

------------8<---------------

<?php

session_start();

Then I'd agree with you, but not if you mean

------------8<---------------
<?php

session_start();
