Deprecated: Function session_register() is deprecated in C:\xampp\htdocs\index.php on line 3

 

Notice: Undefined index: id in C:\xampp\htdocs\index.php on line 4

 

 

<?php

session_start();

session_register("refid_session");

$id=$_GET['id'];

if($id !="") {

if($_SESSION["refid_session"]=="") {

$_SESSION["refid_session"]=$id ;

}

}

include "default.php";

?>

change it to...

<?php
session_start();
$id=$_GET['id'];
if(!isset($_SESSION["refid_session"]) && isset($id)) {
$_SESSION["refid_session"]=$id ;
}
include "default.php";
?>

 

session_register() doesn't exist anymore.

thanks for your help but still i cant get rid of this error Undefined index: id on line 3

try...

<?php
session_start();
if(!isset($_SESSION["refid_session"]) && isset($_GET['id'])) {
$_SESSION["refid_session"] = $_GET['id'];
}
include "default.php";
?>

 

you need to do some kind of validation on $_GET['id']

first of all thanks for fast reply. my friend told me where ever it is throwing the undefined index error, use the language construct isset() to check if the value for 'id' has been set. you already used isset then also isuue not solved :'(

if $_GET['id'] isn't always going to be specified, you should either throw an error or set a default value if need be, like so:

<?php
session_start();
if(isset($_GET['id'])) {
if(!isset($_SESSION["refid_session"])) {
   $_SESSION["refid_session"] = $_GET['id'];
}
} else {
   // either error or default value
   echo "No ID was set!";
}
include "default.php";
?>
