我正在尝试创建我的第一个预备语句，并且在将数据发送到数据库时遇到了麻烦。我正在尝试发送产品信息并将img文件发送到文件夹，然后将永久文件名移动到我的数据库。
截至目前，没有数据发送到我的数据库。唯一发送的是我的图片文件到我的productpics文件夹。我尽可能地尝试自己这样做，并且我已经坚持了很长时间。
有没有人在我的代码中看到准备好的语句有什么问题，或者我是怎么发送导致这个不发送的img文件？
我唯一的错误是我在这下面的$ date变量。我不是太担心，除非它导致这不起作用。我得到的错误是从php错误报告中获取的。
我验证除了此代码之上的img文件以外的所有内容。
//Create
$date = date('Y-m-d H:i:s');
if($validation->passed()) {
if(isset($_POST['create'])){
$product_id = trim( $_POST['product_id'] );
$name = trim( $_POST['name'] );
$price = trim( $_POST['price'] );
$saleprice = trim( $_POST['saleprice'] );
$final_price = trim( $_POST['final_price'] );
$shippingprice = trim( $_POST['shippingprice'] );
$category = trim( $_POST['category'] );
$item_details = trim( $_POST['item_details'] );
$item_details2 = trim( $_POST['item_details2'] );
$description = trim( $_POST['description'] );
$viewproduct_type = trim( $_POST['viewproduct_type'] );
$date = ( $_POST['date_created'] );
$file = "productpics/". $_FILES['file']['name']; // save the filename
move_uploaded_file($_FILES['file']['tmp_name'], $file); // move the file
//Connection
$con = mysqli_connect("localhost","root","","bfb");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
/* create a prepared statement */
if ($stmt = mysqli_prepare($con, "INSERT INTO products ('product_id', 'name', 'price', 'saleprice', 'final_price', 'shippingprice', 'category', item_details', 'item_details2', 'description', 'viewproduct_type', 'date', 'img') VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)")) {
/* bind parameters for markers */
$stmt->bind_param('isiiiisssssis', $product_id, $name, $price, $saleprice, $final_price, $shippingprice, $category, $item_details, $item_details2, $description, $viewproduct_type, $date, $file);
/* execute query */
$stmt->execute();
/* close statement */
mysqli_stmt_close($stmt);
}
}
}
}
}
?>

为什么这不发送的任何想法？
更新代码：
//Create
if($validation->passed()) {
if(isset($_POST['create'])){
$product_id = trim( $_POST['product_id'] );
$name = trim( $_POST['name'] );
$price = trim( $_POST['price'] );
$saleprice = trim( $_POST['saleprice'] );
$final_price = trim( $_POST['final_price'] );
$shippingprice = trim( $_POST['shippingprice'] );
$category = trim( $_POST['category'] );
$item_details = trim( $_POST['item_details'] );
$item_details2 = trim( $_POST['item_details2'] );
$description = trim( $_POST['description'] );
$viewproduct_type = trim( $_POST['viewproduct_type'] );
$file = "productpics/". $_FILES['file']['name']; // save the filename
move_uploaded_file($_FILES['file']['tmp_name'], $file); // move the file
//Connection
$con = mysqli_connect("localhost","root","","bfb");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
/* create a prepared statement */
if ($stmt = mysqli_prepare($con, "INSERT INTO products (product_id, name, price, saleprice, final_price, shippingprice, category, item_details, item_details2, description, viewproduct_type, date, img) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, NOW(), ?)")) {
/* bind parameters for markers */
$stmt->bind_param('isiiiissssss', $product_id, $name, $price, $saleprice, $final_price, $shippingprice, $category, $item_details, $item_details2, $description, $viewproduct_type, $file);
/* execute query */
$stmt->execute();
/* close statement */
mysqli_stmt_close($stmt);
}
}
}
}
}
?>
然后我删除了选项中的名称部分。 查看产品类型 未选中的 标准 选项
答案 0 :(得分：0)
您的列名称使用了不正确的标识符限定符，即单引号'
删除它们，或用刻度线替换它们。
Ticks示例：
(`product_id`, `name`, `price`, `saleprice`, `final_price`,
`shippingprice`, `category`, item_details`, `item_details2`,
`description`, `viewproduct_type`, `date`, `img`)
检查错误会发出语法错误信号。
将$stmt->execute();替换为
if(!$stmt->execute()){trigger_error("there was an error....".$con->error, E_USER_WARNING);}您将看到语法错误。

另外，只有<select>具有name属性而不是<option>。 <option>应包含“value”`。
