Notice: Undefined index: status_krlfilter in D:\Sofwares\XAMPP 7.5.5.0\htdocs\project2\views\filterdata.php on line 46

Answer 1

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.
