$_SESSION and $_POST values not passed across forms

[asmii]

Hi,

 

I am using PHP4 and facing an issue regarding session control.

 

I have a login page login.htm which after taking required details e.g username and password, submits it to submit.php which has the following lines to control a session.

 

//submit.php
session_start();

$uid = isset($_POST['uid']) ? $_POST['uid'] : $_SESSION['uid'];
$pwd = isset($_POST['pwd']) ? $_POST['pwd'] : $_SESSION['pwd'];

$_SESSION['lastaccess']= mktime(); 

 

After matching it with DB, it redirects to index.htm using header("Location:index.htm");

 

Now, Index.htm includes a php file called accesscontrol.php which has the following code :

 

//accesscontrol.php
session_start();
//header("Cache-control: private");
$newtime=mktime();

$tdiff = $newtime - $_SESSION['lastaccess'];
//echo $tdiff;
if ($tdiff > 900)
{
session_unset();
// Finally, destroy the session.
session_destroy();
exit;
}
else
{
$_SESSION['lastaccess']= mktime();
} 

 

The problem is accesscontrol.php can't access $_SESSION['lastaccess'] which leads to further issues.

 

On accesscontrol.php, $_POST variables are also not accessible.

 

 

$uid = isset($_POST['uid']) ? $_POST['uid'] : $_SESSION['uid'];
$pwd = isset($_POST['pwd']) ? $_POST['pwd'] : $_SESSION['pwd'];

 

 

When I checked $uid and $pwd, these are not set.

 

Please help.

 

Thanks in advance.

You mention that your HTML page includes your PHP file - how?

[asmii]

I meant that the index.htm file contains the following command :

include 'accesscontrol.php';

[MasterACE14]

you can try using if and else for this part rather then ternary operator.

$uid = isset($_POST['uid']) ? $_POST['uid'] : $_SESSION['uid'];
$pwd = isset($_POST['pwd']) ? $_POST['pwd'] : $_SESSION['pwd'];

It didn't help much.

 

The actual problem happens in the following.

 

$newtime=mktime();

$tdiff = $newtime - $_SESSION['lastaccess'];

if ($tdiff > 900)
{
header("Location:login.htm");
session_unset();
session_destroy();
exit;
}
else
{
$_SESSION['lastaccess']= mktime();
}

 

accesscontrol.php doesn't find the variable $_SESSION['lastaccess'] which is set in submit.php and thus "if" part is executed rather than "else"

Unless your webserver is processing HTML file with PHP, putting PHP into a .htm file will not work. Rename your index.htm to index.php

My webserver is working as expected. I think issue may be somewhere else.

If you create a file named "test_file.htm" which contains:

<?php
phpinfo();
?>

and invoke it, does anything display?

How does one execute PHP code within a .htm file?

I upgraded my setup and suddenly everything started working form me  I think there was something wrong in my old setup but I still wonder what could be the issue.

Thanks.
