php - 函数缺少参数警告

Question

我已经构建了一个函数来专门处理我的登录系统的一部分。

这是我被击落的错误:

Warning: Missing argument 2 for dbclass::logcon(), called in C:\xampp\htdocs\1\login.php on line 105 and defined in C:\xampp\htdocs\1\assets\includes\functions.php on line 10

这是有问题的代码

if (isset($_POST['submit'])) {

    $user     = $_POST['user'];
    $password = $_POST['password'];

    //To ensure that none of the fields are blank when submitting the form if
    if (isset($_POST['user']) && isset($_POST['password'])) {

        $user     = stripslashes($user);
        $password = stripslashes($password);

        $db1 = new dbclass();
        $db1->openDB();
        $sql = "SELECT * FROM users WHERE username='{$user}' AND password='{$password}'";


        $result = $db1->logcon($sql);
        $row    = mysqli_fetch_array($result);

最后是我的函数。

function logcon($user, $password) {

    $esc_user     = mysqli_real_escape_string($this->conn, $user);
    $esc_password = mysqli_real_escape_string($this->conn, $password);
    $sql          = "select * all from users where username  ='{$user}' AND password='{$password}";
    $result       = mysqli_query($this->conn, $sql);

    if ($result) {
        $numofrows = mysqli_affected_rows($this->conn);
        return $numofrows;
    } else
        $this->error_msg = "could not connect!";
    return false;

}

如您所见，我已经传递了 2 个参数。因此，无可否认，困惑得到控制。

Answer 1

你得到了:

function logcon($user, $password )

但是

$result=$db1->logcon($sql);
