Hi!
I have a problem.
Simple code:

Code: Select all

<?php
 if($_GET["p"]!=""){
 }
?>


I have install xampp version 1.7.4. What is wrong or why?
Thanks for help me.

Maybe it is easier to help you if you tell us, what exactly your problem is.

Uppss ... sorry

This is problem:

Code: Select all

Notice: Undefined index: p in C:\xampp\htdocs\vsiza.si\testi\durs\index.php on line 10

Well, "p" isn't set in your $_GET Array at this point which is a little bit sloppy programming style if you don't check that.
use the php functions isset() or empty() to check if a variable or Array key is set or empty

change

Code: Select all

if($_GET["p"]!=""){

to

Code: Select all

if(isset($_GET["p"]) && $_GET["p"] !=""){

and your Notice is gone.
