Real problem with session code

**hairybobby** · May 16, 2011 09:36

I am having awful trouble with sessions. I have copied the following code into a page and uploaded it. It comes back with the following warning messages

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (session1.php:1) session1.php on line 5

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent

Here is the code. Exactly what am I doing wrong as I copied and pasted it and hacve tried other examples and its uts not working

PHP Code:


<?php
session_start(); 
$_SESSION['views'] = 1; // store 

session data
echo "Pageviews = ". $_SESSION

['views']; //retrieve data
?>

<?php
session_start();
$_SESSION['views'] = 1; // store

session data
echo "Pageviews = ". $_SESSION

['views']; //retrieve data
?>

You forgot to comment out that line?

and then... have some

random enter strokes.

Random enter strokes = broken things.

sorry

This is the code

PHP Code:


<?php
session_start();  
if(isset($_SESSION['views']))
$_SESSION['views'] = $_SESSION['views']+ 1;
else $_SESSION['views'] = 1;
echo "views = ". $_SESSION['views']; 
?>

Its cut and pasted from an example from the internet. It gets the same warning message as I mentioned. It does not increment as it should do

PHP Code:


<?php
session_start();
if( ! isset($_SESSION['views'])){
  $_SESSION['views'] = 1;
}else{
  $_SESSION['views']++;
}

echo 'You viewed this ', $_SESSION['views'], ' times.';

Hi Anthony

I cut and pasted your code with the same warnings and it doesn't work.

**AnthonySterling** · May 16, 2011 10:59

The exact same warning? Place the code I provided in a script by itself, you shouldn't have an issue.

**StarLion** · May 16, 2011 11:06

Make sure there's no whitespace, no blank lines, nothing before the <?php, as well.

**StarLion** · May 16, 2011 11:07

Er... actually... Anthony's code needs a slight modification....

echo 'You viewed this '. $_SESSION['views']. ' times.';

No it doesn't.

Are you sending any output in any scripts before this one?

**hairybobby** · May 16, 2011 12:23

Hi

I just opened the page in wamp server. So far I have been putting everything out onto the internet. Its works perfectly on wamp but on myt webspace it does not work and sends back these warnings.

**hairybobby** · May 16, 2011 13:12

I have the following session script which works on Wamp server.However it fails to work on the internet... why

PHP Code:


<?php
session_start();
if( ! isset($_SESSION['views'])){
  $_SESSION['views'] = 1;
}else{
  $_SESSION['views']++;
}

echo 'You viewed this ', $_SESSION['views'], ' times.';
?>

It comes up with warnings that headers have been sent.

**AnthonySterling** · May 16, 2011 13:19

What is the error?

**hairybobby** · May 16, 2011 15:35

These are the warnings

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (session1.php:1) session1.php on line 5

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent

AND the program doesn't work. The variable stays at 1 and never increments.

IT WORKS with wamp server but on the internet it fails. Its probably something to do with my web hosts.

**AnthonySterling** · May 16, 2011 23:07

You're not using the code I posted, if you we're, the error would be on line 1 not 5. If you post the actual code you're using, we can try to help you.

**hairybobby** · May 16, 2011 23:35

sorry - I copied and pasted the errors from the post earlier. Here are the errors in full

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/castcou7/public_html/dreamsymbolism/forum/session1.php:1) in /home/castcou7/public_html/dreamsymbolism/forum/session1.php on line 2

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/castcou7/public_html/dreamsymbolism/forum/session1.php:1) in /home/castcou7/public_html/dreamsymbolism/forum/session1.php on line 2
You viewed this 1 times.

The code does work - there i nothing wrong with the code. It works on wamp server. So there is something about my server that is not working.
