PHP Notice: Undefined index: error

[vspravin]

Hello guys,

              Iam getting the following php notice in the error_log:

PHP Notice:  Undefined index:  memberId in classErrorHandle.php on line 3

 

Here's the code snippet that causes this notice.

 

<?php

      2        session_start();

      3        $memberId = $_SESSION['memberId'];

      4

 

Any help is highly appreciated....

 

Cheers...

Pravin.

a session with the key member doesn't exist

 

update to

session_start();
$memberId = (!empty($_SESSION['memberId']))?$_SESSION['memberId']:"";

Hi MadTechie,

                      thanks for the solution...it worked!!...but if the variable $memberId was already registered as a session variable, then why does PHP throw such notice...?..

 

thnx

Pravin.

it shouldn't give a notice is it is set, how are you setting it ?

$_SESSION['memberId'] = $memberId; //new /correct way

or

session_register($memberId); //old way

 

If you want your script to work regardless of register_globals, you need to instead use the $_SESSION array as $_SESSION entries are automatically registered. If your script uses session_register(), it will not work in environments where the PHP directive register_globals is disabled.

iam setting it using the old way i.e.

 

session_register($memberId);

i would update your code asap,

 

As of PHP 4.2.0, the default value for the PHP directive register_globals is off, and it was completely removed as of PHP 6.0.0

 

so your going to get more and more problems by leaving it as is.

also the problem here was that i was unable to access the session variable $memberId directly inside a class method.....n that is when php was throwing the Undefined Index notice....

[MadTechie]

you can use sessions in classes, most common problem is either

session_start();

is not used before setting or getting the sesion values

OR

output is being sent before the session_start(); function and making it fail..

 

 

from my first post change

<?php
$memberId = (!empty($_SESSION['memberId']))?$_SESSION['memberId']:"";
?>

 

to

<?php
if (session_id() == "") session_start();
$memberId = $_SESSION['memberId'];
?>

 

check to see if you still get the errors
