mysqli_fetch_array() 期望参数 1 mysqli_result,布尔值在
我在检查我的数据库中是否已经存在Facebook User_id时遇到了一些麻烦(如果没有,它应该接受用户作为新用户,否则只需加载画布应用程序)。我在我的托管服务器上运行它,没有问题,但在我的本地主机上,它给我以下错误:
mysqli_fetch_array() 期望参数 1 mysqli_result,布尔值在
这是我的代码:
<?
$fb_id = $user_profile['id'];
$locale = $user_profile['locale'];
if ($locale == "nl_NL") {
// Checking User Data @ WT-Database
$check1_task = "SELECT * FROM `users` WHERE `fb_id` = " . $fb_id . " LIMIT 0, 30 ";
$check1_res = mysqli_query($con, $check1_task);
$checken2 = mysqli_fetch_array($check1_res);
print $checken2;
// If the user does not exist @ WT-Database -> insert
if (!($checken2)) {
$add = "INSERT INTO users (fb_id, full_name, first_name, last_name, email) VALUES ('$fb_id', '$full_name', '$first_name', '$last_name', '$email')";
mysqli_query($con, $add);
}
// Double-check, the user won't be able to load the app on failure inserting to the database
if (!($checken2)) {
echo "Excuse us " . $first_name . ". Something went terribly wrong! Please try again later!";
exit;
}
} else {
include ('sorrylocale.html');
exit;
}
我已经读过它与我的查询错误有关,但它已经在我的托管服务提供商上工作,所以不可能是它!
