我对 PHP 非常熟悉，但这是我第一次使用 mysqli 库。我试图在数据库中插入一行，但它只是没有插入。我的代码如下所示（为安全起见更改了数据库登录详细信息）：

... // $_REQUEST variables processed
$oConn = new mysqli("localhost","user","password","mydatabase") or die("Error " . mysqli_error($oConn));

$rProvider = $oConn->query("select * from providers where id = $iProviderID");
$aProvider = mysqli_fetch_array($rProvider);
// $aProvider has all the information from the provider that I wanted, so my database connection is working

$oConn->query("insert into bookings (provider_id, provider_rates_id, secret, preferred_date, alternate_date, adults, children, transfer_required, firstname, lastname, email, phone, comments) values
    ($iProviderID, $iRatesID, $sSecret, '$sDate', '$sAltDate', $iAdults, $iChildren, $iTransfer, '$sFirstNameSQL', '$sLastNameSQL', '$sEmailSQL', '$sPhoneSQL', '$sCommentsSQL'");

$iBookingID = $oConn->insert_id;

我没有收到错误，$iBookingID 为 0。该行只是没有插入到数据库中。我浏览了 StackExchange 上的 PHP 手册和类似帖子，但无法解决此问题。

错字-u 忘记添加单引号和括号。

$oConn->query("insert into bookings (provider_id, provider_rates_id, secret, preferred_date, alternate_date, adults, children, transfer_required, firstname, lastname, email, phone, comments) values
    ('$iProviderID', '$iRatesID', '$sSecret', '$sDate', '$sAltDate', '$iAdults', '$iChildren', '$iTransfer', '$sFirstNameSQL', '$sLastNameSQL', '$sEmailSQL', '$sPhoneSQL', '$sCommentsSQL')");

您的代码有错字，您缺少关闭查询的值部分的“）”。

正确的查询：

$oConn->query("insert into bookings (provider_id, provider_rates_id, secret, preferred_date, alternate_date, adults, children, transfer_required, firstname, lastname, email, phone, comments) values ($iProviderID, $iRatesID, $sSecret, '$sDate', '$sAltDate', $iAdults, $iChildren, $iTransfer, '$sFirstNameSQL', '$sLastNameSQL', '$sEmailSQL', '$sPhoneSQL', '$sCommentsSQL');");

如果这不是 php 错误，可以尝试使用echo $oConn->error获取 mysql 查询错误！
