Notice: Undefined index: n in C:\Users\Marseille\Desktop\Activation
W7\UwAmp\www\quezzer\question.php on line 5
this is a code tiped at question.php
$number = (int) $_GET['n'];
why i have this error! i have not understand!
Since this is a get variable you're using, from what I understand is that you maybe trying to run the script questions.php directly. Therefore no get variables are set, try
localhost/yourfolder/questions.php?n=5

Notice: Undefined index: id_desafilter in D:\Sofwares\XAMPP
7.5.5.0\htdocs\project2\views\filterdata.php on line 45
Notice: Undefined index: status_krlfilter in D:\Sofwares\XAMPP
7.5.5.0\htdocs\project2\views\filterdata.php on line 46
that means that your variable may not be defined.
Use isset function.
You should wrap it into a condition like this :
if(!isset($id_desafilter)){
$id_desafilter = "WHAT_YOU_WANT";
}
else{
$id_desafilter = "WHAT_YOU_WANT";
}
This is how you can make sure your variable is define.
But please make sure to join your code to be helped
Have Fun :)

I am looking at my 'WP_DEBUG' errors and the following two errors/notices pop up in a number of PHP files:
Notice: Undefined variable: defaultUI in...
Notice: Undefined variable: compileShortcodeUI in...
I have checked all of the the PHP files and lines specifically and every single one of these refers to this same bit of code:
$compileShortcodeUI .= "<div class='whatInsert whatInsert_".$shortcodeName."'>".$defaultUI."</div>";
What do I need to change to remove these errors?
You have to define the variable initially.
$compileShortcodeUI = ''; // null or any default value
$defaultUI = ''; // null or any default value
$compileShortcodeUI .= "<div class='whatInsert whatInsert_".$shortcodeName."'>".$defaultUI."</div>";

I am getting an undefined index error on this line of code:
switch ($_REQUEST["___p"])
I think I would need to declare the variable. What would I change the above line to?
Either make sure exists beforehand with isset() or just ignore it:
switch (#$_REQUEST["___p"])

I have self written CMS which does not return correct user's IP address with the following:
define("USER_IP", $_SERVER['HTTP_X_FORWARDED_FOR']);
It gives me the following notice:
Notice: Undefined index: HTTP_X_FORWARDED_FOR in /var/www/p00000/data/www/domain.ru/core/maincore.php on line 30
and line 20 = to the line define("USER_IP"...
A few question:
What should I do to get rid of this notice message?
How can I properly get user's IP address?
Thank you for your help!
if (isset($_SERVER['HTTP_X_FORWARDED_FOR'])){
define("USER_IP", $_SERVER['HTTP_X_FORWARDED_FOR']);
} else {
define("USER_IP", $_SERVER['REMOTE_ADDR']);
...
