I am trying to learn php coding and it's now hitting a snag as I keep getting an error:
Error: Notice: Undefined index: msg in C:\\xampp\\htdocs\\kubebook\\index.php on line 12
Source Code:
if ($_GET['msg'] == 1) {
echo "You have successfully registered.";
}
You get that message when you attempt to reference an index or variable that isn't defined. In this case, you aren't passing a yourscript.php?msg=123
param to the script, so $_GET['msg']
doesn't exist. First check if it is set before looking at value
if (isset($_GET['msg']) && $_GET['msg'] == 1) {
echo "You have successfully registered.";
}
