Undefined variable error

[loll]

Hi,

I am just wondering about this "notice".

How do I get rid of these, I know I can jsut ignore it as it isnt a error, but I am trying to start writing my code "properly" which would mean I should not get this notice even with notice reporting on I would think

I assume I would need to use the define function, however the way I Am reading the manual , once a variables are defined, they cant be changed, whereas during the course of a script a variable will change its value, from ehat I understand if I use the define fucntion this will not be possible, am I miss understanding how the define function is used or can I not avoid the notices?

Can you show the code your using it could be that your concatenating a string thats variable doesnt exist until concatenate or your using the ops= e.g.

var += var;

Which again var isnt initiated.

For an example:

the following line produces the notice:

if($_SESSION['status']==1){
}

It produces the notice undefined variable 'status'

That's what would happen if $_SESSION['status'] hasn't been given a value yet. Have you verified that it is by using [man]isset[/man] or [man]empty[/man]?
