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"])

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>";

What I want to do is echo the value of $test on my page, through the uri. I know I'm doing something wrong, but I can't figure out what.
Code:
<?php echo $test?>
URL:
localhost/testMap/test.php?test=hallo
You can get the value of url with a get, and store it in the variable $test and then echo that out.
$test = $_GET['test'];

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
