我正在将我的网站从MySQL转换为MySQLi,但我的所有查询都已停止工作。
我已经尝试了所有内容,但查询没有在数据库中输入任何内容,我将提供一些不起作用的查询。
我在哪里犯了错误?
$sql = array();
$sql = "SELECT my_mailban,mban_reason
FROM members
WHERE playerid = '" . mysqli_real_escape_string($con, $_SESSION['playerid']) . "'";
$mb = array();
$mb = mysqli_fetch_array(mysqli_query($con, $sql));
$_POST['message'] = stripslashes($_POST['message']);
$_POST['subject'] = stripslashes($_POST['subject']);
$_POST['to'] = abs(intval($_POST['to']));
$ sql = array();
$sql = "INSERT INTO member_mail
VALUES ('NULL',
'" . mysqli_real_escape_string($con, $_POST['to']) . "',
'" . mysqli_real_escape_string($con, $_SESSION['playerid']) . "',
'" . mysqli_real_escape_string($con, $_POST['subject']) . "',
'" . mysqli_real_escape_string($con, $_POST['message']) . "',
unix_timestamp(),
'0')";
mysqli_query($con, $sql);
谢谢
