mysqli_fetch_assoc not working with mysqli_stmt_get_result

Question

This is the code to create a user on my website... I need a while loop for my profile img so I used part of this video code https://youtu.be/I4JYwRIjX6c but when I went to try it it gave me this error:

Fatal error: Uncaught TypeError: mysqli_fetch_assoc(): Argument #1 ($result) must be of type mysqli_result, bool given in C:\xampp\htdocs\WravyBike\Includes\functions.inc.php:152 Stack trace: #0 C:\xampp\htdocs\WravyBike\Includes\functions.inc.php(152): mysqli_fetch_assoc(false) #1 C:\xampp\htdocs\WravyBike\Includes\signup.inc.php(60): createUser(Object(mysqli), 'test', 'test@gma...', '', 'test12') #2 {main} thrown in C:\xampp\htdocs\WravyBike\Includes\functions.inc.php on line 152

here is my code: i'm having a problem with the: while ($row = mysqli_fetch_assoc($result)) & $result = mysqli_stmt_get_result($stmt);

    $sql = "INSERT INTO users (usersName, usersEmail, usersTel, usersPwd) VALUES (?, ?, ?, ?);";

// $sql = "INSERT INTO users (usersName, usersEmail, usersTel, usersPwd) VALUES ('$name', '$email', '$tel', '$pwd');";
$stmt = mysqli_stmt_init($conn);
// mysqli_query($conn, $sql);
if (!mysqli_stmt_prepare($stmt, $sql)) {
    header("location: ../signup.php?error=stmtfailed");
    exit();
}
else{
    $pwdHashed = password_hash($pwd, PASSWORD_DEFAULT);
    mysqli_stmt_bind_param($stmt, "ssss", $name, $email, $tel, $pwdHashed);
    mysqli_stmt_execute($stmt);
    $result = mysqli_stmt_get_result($stmt);
    while ($row = mysqli_fetch_assoc($result)) {
        $userid = $row["usersId"];
        $sql = "INSERT INTO profileimg (usersId, status) VALUES ('$userid', 1);";
        $result = mysqli_query($conn, $sql);
        header("Location: ../EditAccount.php");
    }
    mysqli_stmt_close($stmt);
    header("location: ../signup.php?error=none");
    exit();
}

Answer 1

$result = mysqli_stmt_get_result($stmt);

At this part, $result will have a bool value (true) If it successfully inserts record (false) if it fails.

If you want to update userstatus in this 'profileimg' table, use this code

$last_id = $conn->insert_id;

mysqli_stmt_bind_param($stmt, "ssss", $name, $email, $tel, $pwdHashed);
if (mysqli_stmt_execute($stmt)) {
  $last_id = $conn->insert_id;
  $sql = "INSERT INTO profileimg (usersId, status) VALUES ('$last_id', 1);";
  $result = mysqli_query($conn, $sql);
  header("Location: ../EditAccount.php");
}
