Question

我遇到以下代码的问题，并且无法弄清楚我在为MySqli查询准备变量时做错了什么，有人可以帮忙吗？

我认为它可能在bind_param中的第一个参数中，但实际上我不确定。

提前致谢

我不使用mysqli，所以我可能会在这方面做得很好，但你可以试试这个：

$stmt =  $mysqli->stmt_init();
if( $mysqli->prepare("INSERT INTO `search_queries`.`search_results`
    (
        `itemkey`,
        `brand`,
        `holidayresort`,
        `duration`,
        `boardbasis`,
        `roomtypedescription`,
        `deeplinkurl`,
        `offerreference`,
        `currency`,
        `priceperadult`,
        `totalpricebeforediscount`,
        `totalprice`,
        `adjustedprice`,
        `mealsincluded`,
        `transfersincluded`,
        `luggageincluded`,
        `hotelidentifiercode`,
        `hotelname`,
        `starrating`,
        `hotelurl`,
        `outbounddeparture`,
        `outbounddepartureairport`,
        `outboundarrival`,
        `outboundarrivalairport`,
        `outboundflightnumber`,
        `outboundairline`,
        `inbounddeparture`,
        `inbounddepartureairport`,
        `inboundarrival`,
        `inboundarrivalairport`,
        `inboundflightnumber`,
        `inboundairline`
    ) VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)") ){

    $stmt->bind_param("sssssssssssssssssssssssssssssssss", $itemkey,$brand,$holidayresort,$duration,$boardbasis,$roomtypedescription,$deeplinkurl,$offerreference,$currency,$priceperadult,$totalpricebeforediscount,$totalprice,$adjustedprice,$mealsincluded,$transfersincluded,$luggageincluded,$hotelidentifiercode,$hotelname,$starrating,$hotelurl,$outbounddeparture,$outbounddepartureairport,$outboundarrival,$outboundarrivalairport,$outboundflightnumber,$outboundairline,$inbounddeparture,$inbounddepartureairport,$inboundarrival,$inboundarrivalairport,$inboundflightnumber,$inboundairline);

    $itemkey =  $PackageHoliday->ItemKey;
    $brand =  $PackageHoliday->Brand;
    $holidayresort =  $PackageHoliday->HolidayResort;
    $duration =  $PackageHoliday->Duration;

    $totalprice =  $TotalPrice;
    $adjustedprice =  $AdjustedPrice;
    $mealsincluded =  $PackageHoliday->PriceDetails->Extras->MealsIncluded;
    $transfersincluded =  $PackageHoliday->PriceDetails->Extras->TransfersIncluded;

    $hotelidentifiercode =  $PackageHoliday->HotelDetails->HotelIdentifierCode;

    $inboundairline = $PackageHoliday->FightDetails->Inbound->Airline;

    $stmt->execute();

    echo "New records created successfully";

    $stmt->close();
    $mysqli->close();
}
