session information cheers.

redarrow · February 20, 2007

advance thnk you.

Hi there all i need to no if this is correct you can set a session to a varable name and the session will be as strong as a session not using a session varable name set.

example.

<?php
$id=$_POST['id'];	
$id=$_SESSION['id']=$b['id'];
$name=$_POST['name'];
$name=$_SESSION['name']=$b['name'];
$password=$_POST['password'];
$password=$_SESSION['password']=$b['password'];
?>

As long as you have session_start();, because all your doing is making an assignment $a = $b = $c; <= $a and $b are assignments of $c! If you don't use session_start();, then all the $_SESSION[...] assignment (types) will just be ignored, (issue no warnings)!

do you need session_start () on the login page where the login form is i didnt think so but do you.

marcus · February 20, 2007

Wherever you're starting your sessions you need session_start(); on the top of your script

<?php
session_start();
//etcccc
?>

how can a session get killed from this page

<?php session_start();



$db=mysql_connect("xxxx","xxx","xxx");

It dies because you're starting a new session (based on session id), which will clear all the data from their past session.

redarrow · February 20, 2007

what lines that on lol?

tom100 · February 20, 2007

This thread is getting confusing...

Any page that sets or reads SESSION variables must have session_start() before any output.

If the session is dieing, you most likely did not include the session in the page that created the session or the page that is reading the session.

If you want to destroy a session, use session_destroy()

marcus · February 20, 2007

Your first line,

<?php session_start();

redarrow · February 20, 2007

It dies because you're starting a new session (based on session id), which will clear all the data from their past session.

you statement does not make scence ok tell me more what can you see whats wrong ok.

tom your right but i am at the end of this one project my 60.oooth please help i no all session information but need help.

Jessica · February 20, 2007

$id=$_SESSION['id']=$b['id'];

This doesn't even make sense.

wtf are you trying to do?

redarrow · February 20, 2007

does make sence

$id//varable name

=//equal

$_SESSION['id']// session id of

=$b['id'];==while loop

now id becomes session name $id

there you go young lady an example

<?php

$query_blog="select * from blog_register where name='$name' and password='$password' ";
$result_blog=mysql_query($query_blog);

while($b=mysql_fetch_assoc($result_blog)){

$id=$_POST['id'];	
$id=$_SESSION['id']=$b['id'];
$name=$_POST['name'];
$name=$_SESSION['name']=$b['name'];
$password=$_POST['password'];
$password=$_SESSION['password']=$b['password'];

if(mysql_num_rows($result_blog)==1){

header("location: blog.php");
exit;
}
}

?>

tom100 · February 20, 2007

It might make sence, but it doesn't make sense.

Please describe the exact problem and what you are trying to accomplish. Try and be as clear as possible.

Jessica · February 20, 2007

That's not quite how it works. What you're trying to do still doesn't make any sense. You set $id to $_POST['id'], then immediately overwrite it with the result of $_SESSION['id'] = $b['id'] which will return true. So $id will be true.

redarrow · February 20, 2007

that correct then on all pages the $id is session of the id try it your see.

Jessica · February 20, 2007

you speak english good ok.

Greaser9780 · February 20, 2007

Where you said how could sessions be destroyed from this page, I saw no place where they should be. THe problem might lie in the page after that. If you don't have session_start() at the top on that one it will kill it.

redarrow · February 20, 2007

if i set it by the rules of session's as below, does this code mean that the $varable's for id name and password are now $id $name $password from the session.

or will i have to set them to the session

example

<?php sesion_start();

$name=$_SESSION['name'];
?>

<?php session_start();

$query_blog="select * from blog_register where name='$name' and password='$password'  ";
$result_blog=mysql_query($query_blog);

while($b=mysql_fetch_assoc($result_blog)){

$_SESSION['id']=$b['id'];
$_SESSION['name']=$b['name'];
$_SESSION['password']=$b['password'];

if(mysql_num_rows($result_blog)==1){

header("location: blog.php");
exit;
}
}
?>
