Problem with session

[nati]

Hello everybody,

 

I have a site at http://www.djordjeweb.nl/compshop/.

Locally, everything works normally, but on web session doesn't start at all.

In top right corner there is a link "Prijava" which means "Login".

 

Here is code for starting session.

 

<?php
$logovan = $_GET['ime'];
$proizvod = $_GET['proizv'];
  if ($logovan != '')
  {
  session_start();
  session_regenerate_id();
  $_SESSION['sesija_sesname'] = session_id();
  $_SESSION['sesija_loguser'] = $logovan;
  $_SESSION['sesija_tekuca_kat'] = 0; 
  $_SESSION['sesija_artikal'] = $proizvod;
  $_SESSION['sesija_korpa'] = ''; 
  $_SESSION['sesija_ukupna_cena'] = 0;
  $_SESSION['sesija_ukupno_artikala'] = 0;
  if ($proizvod == '')
  {header('Location: index.php');}
  else
  {header('Location: detail.php');}
  }
?>

 

Where am I wrong, can anyone help, please?

 

Tnx in advance,

Nati

try putting session start at the top of the code, make sure it is before everything else (including any PHP or html code)

[nati]

I put session_start at the top, as you suggested, but it still doesn't work  .

 

Any ideas?

 

 

[DeanWhitehouse]

Is the IF statement being run, try putting an echo in the statement.

[revraz]

Have you checked your PHP.INI to verify the session save path is valid?

[DeanWhitehouse]

Quick way to do it if you don't have access to php ini

 

echo ini_get('session_save_path');

 

I think that is correct

[nati]

If statement is run, but now some errors occured. First line is my message.

 

if statement works

Warning: session_regenerate_id() [function.session-regenerate-id]: Cannot regenerate session id - headers already sent in /home/fuzzy/domains/djordjeweb.nl/public_html/compshop/sesija.php on line 9

 

Warning: Cannot modify header information - headers already sent by (output started at /home/fuzzy/domains/djordjeweb.nl/public_html/compshop/sesija.php:7) in /home/fuzzy/domains/djordjeweb.nl/public_html/compshop/sesija.php on line 18

 

I'll put now a code to see session_save_path.

 

 

[nati]

Here is my new code for starting session with your suggestions:

 

<?php
session_start();
$logovan = $_GET['ime'];
$proizvod = $_GET['proizv'];
  if ($logovan != '')
  {
  echo "Session path: ".ini_get('session_save_path');
  session_regenerate_id();
  $_SESSION['sesija_sesname'] = session_id();
  $_SESSION['sesija_loguser'] = $logovan;
  $_SESSION['sesija_tekuca_kat'] = 0; 
  $_SESSION['sesija_artikal'] = $proizvod;
  $_SESSION['sesija_korpa'] = ''; 
  $_SESSION['sesija_ukupna_cena'] = 0;
  $_SESSION['sesija_ukupno_artikala'] = 0;
  if ($proizvod == '')
  {header('Location: index.php');}
  else
  {header('Location: detail.php');}
  }
?>

 

And here is what I get when I try to login:

 

Session path:

Warning: session_regenerate_id() [function.session-regenerate-id]: Cannot regenerate session id - headers already sent in /home/fuzzy/domains/djordjeweb.nl/public_html/compshop/sesija.php on line 7

 

Warning: Cannot modify header information - headers already sent by (output started at /home/fuzzy/domains/djordjeweb.nl/public_html/compshop/sesija.php:7) in /home/fuzzy/domains/djordjeweb.nl/public_html/compshop/sesija.php on line 16.

 

Session_save_path is empty  ???

 

You can try to log in as natasa/natasa.

[DeanWhitehouse]

try , i disabled the header to stop it redirecting and producing errors

<?php
session_start();
session_regenerate_id();
$logovan = $_GET['ime'];
$proizvod = $_GET['proizv'];
  if ($logovan != '')
  {
  echo "Session path: ".ini_get('session_save_path');
  $_SESSION['sesija_sesname'] = session_id();
  $_SESSION['sesija_loguser'] = $logovan;
  $_SESSION['sesija_tekuca_kat'] = 0; 
  $_SESSION['sesija_artikal'] = $proizvod;
  $_SESSION['sesija_korpa'] = ''; 
  $_SESSION['sesija_ukupna_cena'] = 0;
  $_SESSION['sesija_ukupno_artikala'] = 0;
  if ($proizvod == '')
  {//header('Location: index.php');}
  else
  {//header('Location: detail.php');}
  }
?>

[nati]

Here is the result with commented header commands:

 

Session path:

Warning: session_regenerate_id() [function.session-regenerate-id]: Cannot regenerate session id - headers already sent in /home/fuzzy/domains/djordjeweb.nl/public_html/compshop/sesija.php on line 8

Then i take it you aren't showing us the full code

[uniflare]

ou cannot echo/print/print_r/break ?> or otherwise send any output to the browser before you use session_regenerate_id() or session_start();

 

There is a sticky topic on header errors, just need to look:

"HEADER ERRORS - READ HERE BEFORE POSTING THEM"

on the main php help forum: http://www.phpfreaks.com/forums/index.php/board,1.0.html

[DeanWhitehouse]

Or just read my first reply

try putting session start at the top of the code, make sure it is before everything else (including any PHP or html code)

[nati]

At first, I have to say I do show you the full code, but now I noticed you also deleted a line:

 

session_regenerate_id();

 

which I didn't delete. You mentioned only headers, sorry, I'll delete this line and see what will I get.

 

Second, session_start is on the top.

 

Third, echo command I was suggested to put to see if "if ($logovan != '')" is being run.

 

[DeanWhitehouse]

I didn't delete anything

[uniflare]

read my post, your header errors will be fixed if you follow the instructions.

[nati]

Sorry one more time, you moved session_regenerate_id under the session_start, I see now.

 

New change will be upload now.

[nati]

Here is what I get now:

 

Session path:

 

And my code is:

 

<?php
session_start();
session_regenerate_id();
$logovan = $_GET['ime'];
$proizvod = $_GET['proizv'];
  if ($logovan != '')
  {
  echo "Session path: ".ini_get('session_save_path');
  $_SESSION['sesija_sesname'] = session_id();
  $_SESSION['sesija_loguser'] = $logovan;
  $_SESSION['sesija_tekuca_kat'] = 0; 
  $_SESSION['sesija_artikal'] = $proizvod;
  $_SESSION['sesija_korpa'] = ''; 
  $_SESSION['sesija_ukupna_cena'] = 0;
  $_SESSION['sesija_ukupno_artikala'] = 0;
  if ($proizvod == '')
  {/*header('Location: index.php');*/}
  else
  {/*header('Location: detail.php');*/}
  }
?>

[DeanWhitehouse]

Ahh my bad, just googled it

 

should be

 

ini_get('session.save_path');

[nati]

Ah, no problem, mistakes happen, I'll change it  .

[nati]

Hmm, the result is the same 

[DeanWhitehouse]

add error_reporting(E_ALL); to the top before session_start();

are their any errors?

[nati]

No errors, still just:

 

Session path:

Hello again  ,

 

I found what made my session didn't work, but I still don't understand why  ???.

 

I made changes to pages which use session variables and wrote $_SESSION['blabla'] instead of $blabla and now it works!

 

What I am confused about is that I thought (obviously wrong  ) session variables should be declared as $_SESSION['blabla'] once and lately could be referenced to as $blabla. That worked fine at my local environment.

 

What can cause that works in one environment and doesn't work in another?

And what is correct way to do?

 

Tnx a lot!

Nati
