PHP Mysqli - 插入不保存到数据库

Question

我有一个函数应该将数组存储到我的mysql表中，但我的数据库中没有显示任何内容。这是我第一次使用Mysqli，因为我曾经使用Mysql。

该函数传递一个$uniqueRef ID，该ID保存在数据库中，工作订单数组$coreSales是另一个保存在数据库中的数组，$mysqli通过了MYSQLI连接。

这是我的代码：

function storeInDB($uniqueRef, $wo, $coreSales, $mysqli){
    $accountStatus = 0;
    $requiresAttention = 2;

    $stmt = $mysqli->prepare("INSERT INTO `workorder`(`id`, `uniqueRef`, `rep`, `repemail`, `date`, `event`, `otherNotes`, `repNotes`, `bookingNotes`, `reqInstallDate`, `tripplePlayPromo`, `fullName`, `address`, `contactNumber`, `accountNumber`, `custID`, `custEmail`, `cblPackage`, `cblNotes`, `cblEquipment`, `cblPromo`, `internetPackage`, `internetNotes`, `internetEquipment`, `internetPromo`, `phonePackage`, `phonePromo`, `portingNumber`, `phoneBook`, `portornew`, `cellorlandline`, `companyPortingfrom`, `servicesToDisco`, `alarm`, `intercom`, `nameOnBill`, `cellAccount`, `fromAddress`, `phoneNotes`, `creditName`, `creditContactNumber`, `creditAddress`, `creditAccount`, `status`, `requiresattention`, `creditAmount`) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)");


$stmt->bind_param('issssssssssssssssssssssssssssssssssssssssssiii',
    $idNum,
    $uniqueRef,
    $wo['rep'],
    $wo['repemail'],
    $wo['date'],
    $wo['event'],
    $wo['otherNotes'],
    $wo['repNotes'],
    $wo['bookingNotes'],
    $wo['reqInstallDate'],
    $wo['tripplePlayPromo'],
    $wo['fullName'],
    $wo['address'],
    $wo['contactNumber'],
    $wo['accountNumber'],
    $wo['custID'],
    $wo['custEmail'],
    $wo['cblPackage'],
    $wo['cblNotes'],
    $wo['cblEquipment'],
    $wo['cblPromo'], 
    $wo['internetPackage'],
    $wo['internetNotes'], 
    $wo['internetEquipment'], 
    $wo['internetPromo'], 
    $wo['phonePackage'], 
    $wo['phonePromo'],
    $wo['portingNumber'], 
    $wo['phoneBook'],
    $wo['portornew'], 
    $wo['cellorlandline'], 
    $wo['companyPortingfrom'], 
    $wo['servicesToDisco'], 
    $wo['alarm'],
    $wo['intercom'], 
    $wo['nameOnBill'], 
    $wo['cellAccount'], 
    $wo['fromAddress'],
    $wo['phoneNotes'],
    $wo['creditName'], 
    $wo['creditContactNumber'],
    $wo['creditAddress'],
    $wo['creditAccount'],
    $accountStatus,//Status
    $requiresAttention,
    $creditAmount);//Requires Attention



    echo $mysqli->error;
    $stmt->execute();
    $idNum = $mysqli->insert_id;
    $stmt->close();

    echo "<br>Stored in DB ID#" .$idNum ;
    return $idNum;
}
