[SOLVED] session problem

[janim]

hi all

i have session called name :

$myname=$_session['name'];

already stored

but why it changes

 

i have page showing books so when i open this page the session changes to the name of the book

why this happens

and this happens just in my server but in localhost everything ok

 

why it would change ?

 

thanx

Post your script please, so we can examine it.

sorry phpSensei i can't post all the code it's little big and going between the html code

so it's like that in general :

 

 
<?php
// for the login page :
$name = $_POST['myname'];
$_SESSION['login']=true;
$_SESSION['name']=$name;
?>

 

then i check for lgin or not :

 

<?php 

$check = $_SESSION['name'];
	echo "Welcome back ".$check."<br>";
		echo "<a href=\"profile.php?name={$check}\">My profile</a>";
?>

 

so in my local host it's work good but in my server it's change the session name to the book name in that's page

the book name is comming from mysql like this :

 

<?php
$new=mysql_db_query($b,"select * from $books where id='$id'") or die ("".mysql_error());
if(mysql_num_rows($new)){
$q=mysql_fetch_array($new);
$name=$q[bookname]; 
}
?>

 

so what is the problem ???

why my session name changes to the book name ?

 

 

[PFMaBiSmAd]

The reason why the $_SESSION['name'] is getting changed when $name=$q[bookname]; is executed is because register globals are ON and the $name variable is the same as $_SESSION['name'].

 

You need to use unique variable names when register globals are on. You should also turn off register globals.

but how i can know more about session and global variables ?
