<form action="index3.php" method="post">
    email: <input type="text" name="email"/>
    passwort: <input type="text" name="passwort"/>
    name: <input type="text" name="name"/>
    <input type="submit" value="Registrieren" name="submit"/>
</form>


<?php
    $file = "./logingfile.txt";
    $filename = "./logingfile.txt";
    $result = false;
    $servername = "localhost";
    $user = "root";
    $pw = "";
    $db = "user"; 

    $con = new mysqli($servername, $user, $pw, $db);

    if($con->connect_error){
        die("ende".$con->connect_error);    
    }
    $hashed = hash('sha256', $_POST["password"]); // i think here is the problem
    $sql = "INSERT INTO login (id, name, email, passwort) 
    VALUES (NULL,'".$_POST["name"]."','".$_POST["email"]."','".$hashed."' )"; 

    $result = $con->query($sql);

    if($result == false){
        echo $con->error;
    }
    echo $_POST["passwort"];
    echo $hashed;


    file_put_contents($filename, $sql, FILE_APPEND);
    file_put_contents($filename, "n", FILE_APPEND);



?>

P.S: i know this isnt the securest code, its only for test purposes where i can understand a little bit about sql injections

Answer

That’s because of this line:

$hashed = hash('sha256', $_POST["password"]);

It should be $_POST["passwort"], just a mispelling
