我一直在从事一个自我项目，目标是成为任天堂3ds数据库。但是，在插入部分会出现以下错误。
“您的sql语法有错误；请查看与mysql服务器版本相对应的手册，以获取在第1行的“”附近使用的正确语法
我已经检查了所有被请求的文件，但它们都没有那个''。
以下是代码：
添加游戏.php

<?php
require 'connect.php';
require 'phpqrcode/qrlib.php';
$c = connectDB();
define('IMAGE_WIDTH',200);
define('IMAGE_HEIGHT',200);
$boxDir = "../boxdb/";
$name = $_POST['name'];
$link = $_POST['link'];
$desc = $_POST['description'];
$rel = $_POST['releaseDate'];
$reg = $_POST['region'];
$gen = $_POST['genre'];
$box = $_FILES['box']['name'];
$temp_box = $_FILES['box']['tmp_name'];
$qrName = '../qrdb/' . $name . '.png';
$qr = QRcode::png($link, $qrName);
move_uploaded_file($temp_box, $boxDir.$box);
if(!empty($reg) and is_array($reg)) {
    $regArr = implode(' , ',$reg);
}
if(!empty($gen) and is_array($gen)) {
    $genArr = implode(' , ',$gen);
}
$ins = mysqli_query($c,"INSERT INTO db(gameName,ciaLink,gameDesc, releaseDate, region, genre, gameBox,qr) VALUES('$name','$link','$desc','$rel','$regArr','$genArr','$temp_box','$qr'");
if($ins){
    echo 'OK';
}
else{
    echo mysqli_error($c);

连接.php

<?php
define("HOST","localhost");
define("USER","root");
define("PASS","");
define("DB","3ds");
function connectDB(){
    $c = mysqli_connect(HOST,USER,PASS,DB);
    return $c;
}
?>

可能有什么问题？如果有帮助的话，我在Windows7上使用的是WAMPServer643.1.4。
