when I insert data to my database i get error like below: https://gyazo.com/501ee97212001fc7ffe65c1abc1048c4 “Notice: Undefined variable: POST in C:/wampp64/www/wspoladm.php on line 3” Values are added, expect the first one in lane 3. I declared this varriable in every script and I have no idea what’s wrong. Thanks for answer guys. Php script:
require "conn.php";
$czy_dane=$POST["czy_dane"]; -- line 3
$umowa = $_POST["umowa"];
$nazwa=$_POST["nazwa"];
$kategorie=$_POST["kategorie"];
$opis=$_POST["opis"];
$transfer=$_POST["transfer"];
$zabezpieczenia=$_POST["zabezpieczenia"];
$dane=$_POST["dane"];
$mysql_qry1 = "insert into wspoladm_panel(czy_dane,nr_umowy,nazwa,kategorie,opis,transfer,zabezpieczenia,dane)
values('$czy_dane','$umowa','$nazwa','$kategorie','$opis','$zabezpieczenia','$transfer','$dane')";
if($conn->query($mysql_qry1) === TRUE) {
echo "Pomyslnie dodano dane";
}
else
{echo "Error: " . $mysql_qry1 . "<br" . $conn->error;

$conn->close();

Answer
In your php code.
Use $_POST instead of $POST.
Code
require "conn.php";
$czy_dane=$_POST["czy_dane"]; -- line 3
$umowa = $_POST["umowa"];
$nazwa=$_POST["nazwa"];
$kategorie=$_POST["kategorie"];
$opis=$_POST["opis"];
$transfer=$_POST["transfer"];
$zabezpieczenia=$_POST["zabezpieczenia"];
$dane=$_POST["dane"];
$mysql_qry1 = "insert into wspoladm_panel(czy_dane,nr_umowy,nazwa,kategorie,opis,transfer,zabezpieczenia,dane)
values('$czy_dane','$umowa','$nazwa','$kategorie','$opis','$zabezpieczenia','$transfer','$dane')";
if($conn->query($mysql_qry1) === TRUE) {
echo "Pomyslnie dodano dane";
}
else
{echo "Error: " . $mysql_qry1 . "<br" . $conn->error;
}
$conn->close();
