Question

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，它只是不插入。我的代码看起来像这样（为安全起见，数据库登录详细信息已更改）：

... // $_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;

我没有收到任何错误，$ iBookingID为0.该行没有插入到数据库中。我已经阅读了StackExchange上的PHP手册和类似的帖子，但是无法解决这个问题。

Answer 1

错误 - 你忘了添加单引号和括号。

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

Answer 2

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

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

    $iBookingID = $oConn->insert_id;
    echo $iBookingID;

Answer 3

你的代码上有一个错字，你错过了关闭＆＃34;）＆＃34;您查询的值部分。

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');");

Answer 4

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

PHP mysqli没有插入数据库
