About PHP Sessions

Hi Everibody

I have a php (index.php) page from which I post to another php page (login.php)

<?php
include("conect.php");
$link=Conectarse();
$Sql="select nombres, apepat, apemat from lhn_cliente where emailpersonal='".$POST["txtCodUsu"]."' and password='".$POST["txtPassword"]."'";

$result = mysql_query($Sql,$link);

while($row = mysql_fetch_array($result))
{
	//session_name("lhn");
	//session_start();
	session_register("usunom");
    $HTTP_SESSION_VARS["usunom"] = $row["nombres"];
	session_register("usuapepat");
    $HTTP_SESSION_VARS["usuapepat"] = $row["apepat"];
	session_register("usuapemat");
    $HTTP_SESSION_VARS["usuapemat"] = $row["apemat"];

}
header("Location: index.php");

Now from the index.php, actually from the included file top.php which is a php page that is in charge of displaying the header of the page, I have the following code (part of the code):

<?php

print("PHP Version ".phpversion()."\n");
print("Bienvenido=".$HTTP_SESSION_VARS['usunom']);

My problem is that after "Bienvenido", there is no data, I'm sure the SQL query returns data becuase I'm sure the posted data arrives and therefore the SQL query is OK.

Please tell me where is my mistake....
Thanks

if you include session_start() in your header.php and you include header.php in everything then you should be fine with sessions.

i was having a stupid mistake just now with sessions. i was not closin gthe session for one. whoops, simple fix. secondly i was not at all setting up the session correctly or at all actually. include the session at the top of every page. at least before anything that needs it

Uhmm, so you mean my code is OK? how do I include the session at the top of every page? explain me please thanks 🙂

i didn't bother to look at your code. you can debug that yourself. looks simple enough.

at the top of everypage do this:

session_start();

it takes no params.

this will save the stae between pages. if anything make a class, call it once in one file like perhaps your header, and call the header in each file. that should take care of this. i do an init and then the header but it'll all work the same. that should fix your problem with not remembering something from the last page

see what is happening is that your session is only saving to that one page. it's in the session trust me. and the query is taking it out. but the problem is that you want it to go to the next page. use session_start(); at the top of each page and you should be fine.

rock out bro

It says

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/nuessoft/public_html/losheraldosnegros/recuerdos.php:4) in /home/nuessoft/public_html/losheraldosnegros/includes/top.php on line 2
PHP Version 4.4.0 Bienvenido=

I put the session_start(); at the top of index.php, in the included file top.php and in the login.php page but it raises that error 🙁

http://us3.php.net/session_start

your PHP seems to be correct so i can't blame that. and i've never gotten that error so i don't know what's going on. BUT you included it in the top of all your files which is right but did you make sure that you are not using session_start() more than once? if you have it in your header and then in your index that might be the problem you are having. which is odd because i've actually tested for that and it didn't screw up on mine...

🙁 well.... I'll try again, now it's time to sleep here 🙂
Thank you very much for your time, later I'll continue working on it 🙂 bye for now 🙂

So in other words, something on line 4 of recuerdos.php is producing output. After you've produced output, you can't send headers any more (search the forums for the text of the error message for more info).
