Getting error message that wasn't there before...

derekbelcher · April 22, 2009

I recently added a line of php code to a checklogin page and am getting some weird error:

Warning: session_register() [function.session-register]: open(/home/edlegs/tmp/sess_bc52abb2dba095cba858e0238af95f35, O_RDWR) failed: Permission denied (13) in /home/p2r71184/public_html/admin/checklogin.php on line 59

Any ideas?

It would be nice if you told us what line of code you added.

You have at least two problems -

1) The folder /home/edlegs/tmp/ does exist and is what session.save_path is set to but it does not have the proper permissions for php to create the session data files. This could either be due to an actual permission problem or session.save_path has been changed to a folder that is different from what it was.

2a) session_register() was depreciated long ago in php4.2 in the year 2002 and does not work when register_globals are off. session_register() and register_globals have been completely removed in php6. You must use $_SESSION variables instead.

2b) This error - Your script possibly relies on a session side-effect which existed until PHP 4.2.3... is only output when register_globals are off, which means that they are off, which they should be and that session_register() has no effect in your code.

alright, i changed the session_register to $_SESSION. That worked. Now I can get to the "successful login page", however, the errors are still there at the top of the page. It is finding a problem with the line that has this on it:

session_start()

I checked the spaces and additional characters and found none. This is frustrating because I didn't change anything from last week and it worked fine then.

Here is the complete code for the successful login page:

<?

session_start();

if(!session_is_registered(myusername)){

header("location:adminLogin.php");

}

ini_set("session.cookie_lifetime", "60")

?>

<?php $host="localhost"; // Host name

$username="p2r71184"; // Mysql username

$password="692134a"; // Mysql password

$db_name="p2r71184_regMembers"; // Database name

$tbl_name="MEMBERS"; // Table name

// Connect to server and select databse.

mysql_connect("$host", "$username", "$password")or die("cannot connect");

mysql_select_db("$db_name")or die("cannot select DB");

?>

session_is_registered() is related to session_register() and does not work. Must be changed to $_SESSION

What is the current error message?

And - ini_set("session.cookie_lifetime", "60"); must go before every session_start() to have any effect.

Alright...changed the session_is_registered. Give it a try if you would like to:

Go to: http://www.mercercountyfa.org/stationAdmin/adminLogin.php

Username: admin Password: 12345

Here is the code for the page you get when you login successfully:

<?php

session_start();

if($_SESSION['myusername']){

header("location:adminLogin.php");

}

ini_set("session.cookie_lifetime", "60")

?>

<?php

$host="localhost"; // Host name

$username="p2r71184"; // Mysql username

$password="692134a"; // Mysql password

$db_name="p2r71184_regMembers"; // Database name

$tbl_name="MEMBERS"; // Table name

// Connect to server and select databse.

mysql_connect("$host", "$username", "$password")or die("cannot connect");

mysql_select_db("$db_name")or die("cannot select DB");

?>
