problem with session variables

[Garry Jones]

Elsewhere on a form page I am declaring a variable

*************** *************** *
session_start() ;
$_SESSION['testvar'] = "sometext";

At the top of the page that will process the form code I have this line.

session_start() ;
$testppp=$_SESS ION['testvar'];

echo $testppp;

*************** *************** *

But nothing is echoed. What am I missing?

Re: problem with session variables

If you use PHP on Windows you have to define session.save_pa th in case
you use sessions stored as files. Check this:

http://ro2.php.net/manual/en/function.session-save-path.php

Let me know it this was the problem.

Are you calling session_start() before ANY output is sent to the
browser? This includes html, php output or even white space.

No. Are you supposed to?

I can session_start in similar code on other sites and they work ok.

My php session start is in a segment of code called in by a ´condition"
being met)

This problem is persisting. I need to carry a variable forward past a form
being read in and processed,

This problem is persisting.

More code

form code
session_start() ;
$_SESSION['testvar'] = "sometext";
echo $_SESSION['testvar'];

At the top of the page that will process the form code I have this line.
session_start() ;
echo $_SESSION['testvar'];

The first "echo $_SESSION['testvar']" works
The second one does not so the session varible is reset to null. But WHY?

[...]

At the top of the page that will process the form code I have this line.
session_start() ;
echo $_SESSION['testvar'];

Try this in the page that will process the form code

if (!headers_sent( )) {
session_start() ;
echo $_SESSION['testvar']
} else {
echo 'Cannot start session. Headers have already been sent.';
}

Then, if it complains with "Cannot start session. ..." move the lines up
in the source code until it stops complaining.

Yes. Try adding this code just before you call session_start() and
you'll see your error:

ini_set('displa y_errors', 1);
error_reporting (E_ALL & ~E_NOTICE);

sessions_start( ) must be the first command before you use any output
function

Yes. Try adding this code just before you call session_start() and
you'll see your error:

The problem was that my web hotel had this function disabled. I was able to
go in and change the setting and now it works.

Thanks for all your replies.
