我正在尝试为我的项目创建一个登录系统,但在登录期间发生了错误。错误说'next()要求参数1为数组,布尔值为'。
public function login(Customer $c) {
$sql = "select * from customer where username = ? and password = ?";
try {
$username = $c -> getUsername();
$password = $c -> getPassword();
$stmt = $this -> getConnection() -> prepare($sql);
$stmt -> bind_param('ss', $username, $password);
$res = $stmt -> execute();
while (next($res)) {//error occurred on this line
return true;
}
} catch (SQLiteException $ex) {
echo $ex;
}
return false;
}
答案 0 :(得分:4)
execute()成功时返回true,失败时返回false。
像这样使用:
$stmt->execute();
while($row = $stmt->fetch_assoc())
{
return true;
}
