sessions driving me demented

[petermeachem]

This should be easy.
In login.php I've got
session_start();
echo $_POST['username'];
$HTTP_SESSION_VARS["username"] = $_POST['username'];

I used $HTTP_SESSION_VARS as none of the other methods I found worked. This seemed to work 1/2 an hour ago, but I now get a blank session file. The echo gives the correct value for username of admin.

Assuming you're in a recent version of PHP go ahead and switch to

$_SESSION['username']=$_POST['username'];

Other than that though... it's hard to say more with the rest of the code... here's a simple test though...

File1:
<?php
session_start();
$_SESSION['testval']='Foo';
echo '<a href="file2.php">Test the session</a>';
echo '<hr /><pre>';
print_r($_SESSION);
echo '</pre>';
?>

File2:
<?php
session_start();
echo '<pre>';
print_r($_SESSION);
?>

No easier way to see if you're sessions are functioning properly.

What version of PHP are you running?

4.1.2

Are you sitting there day and night pressing F5? You always seem to answer within about a ms!

File 1 looks like
Test the session
--------------------------------------------------------------------------------

Array
(
[testval] => Foo
)

And file 2

Array
(
)


The session file is empty.

This isn't right is it?

login.php now contains

session_start();
session_register('username');
header( "Location:

http://nt4work/php/BusinessCards.php"

);

and the session file contains
username|s:5:"admin";

The top of BusinessCards.php contains

<?php
session_start();
if(session_is_registered('username')){
}
else{
header( "Location:

http://nt4work/php/login.htm"

);
}

Running this creates a second session file which is blank and the code pops back to login.htm (which calls login.php on Submit)

I use Opera as my main web browser. One feature it has is to automatically reload a given page on an arbitrary schedule.

I don't suppose you have an opportunity to upgrade, do you? There's lots of bugfixes and feature enhancements between what you're running and the current version.


With what web server are you running PHP? If it's IIS, there's a known issue (described as a feature by Microsoft) wherein IIS does not transmit cookies when you set the "Location:" header.

It's pws on nt4.

I think what I'll do is wait until Easyspace get their collective fingers out and sort me a database. Doing it on my pc was supposed to be a time saver!

Yeah, PWS is the source of your problem.

When you invoke session_start() in the first script, a session store is created on your drive and the cookie is set to be sent to the browser. The session value is stored. Then the "Location:" header prevents the session id cookie from being transmitted to the browser.

So when you run the next script and it invokes session_start(), PHP doesn't find a session id cookie so it creates a new id and session store and sets the new value in a cookie.

There is a workaround: use of the "http-equiv" <meta> tag in your HTML output:

<META HTTP-EQUIV="Refresh" CONTENT=";URL=http://nt4work/php/BusinessCards.php">


You can also do the same thing with JavaScript.
