Notice: Undefined index: var3 in /storage /public_html/xxxxxx.php on line 11

and my PHP script : `

            // Include config file
             require_once 'config.php';
             $v1 = $_POST["var1"];
             $v3 = $_POST["var3"];

             $sql = "INSERT INTO rora (var1,var3)
             VALUES ('$v1', '$v3')";

             if ($link->query($sql) === TRUE) {
             echo "New record created successfully";}
             else {
             echo "Error: " . $sql . "<br>" . $link->error;
                   }

                $link->close();`
