问题是您在设置图像名称后绑定查询上的参数，尝试这样：

$server = "localhost";
$username = "root";
$password = "root3";
$dbname = "sampledb";

// creat connection
$connection = new mysqli($server, $username, $password, $dbname);

// check the connection
if ($connection->connect_error)
{
     die("connect to database failed :" . $connection->connect_error);
}

// check value from select menu 
if ($_POST['typelist'] == 'item') 
{

  // prepare and bind parameters
  if (isset($_FILES['item_image'])) 
  {

    // set all parameters FIRST TO BIND ON THE QUERY
    $image = $_FILES['item_image']['name']; // Now you have the image name
    $temp = $_FILES['item_image']['tmp_name'];
    $path = "../images/items/$image";

    move_uploaded_file($temp, $path);

    $manufacturing_year = $_POST['manufacturing_year'];
    $length = $_POST['item_length'];
    $width = $_POST['item_width'];
    $weight = $_POST['item_weight'];
    $price = $_POST['item_price'];
    $description = $_POST['item_description'];
    $model = $_POST['item_model'];

    $itemquery = $connection->prepare("insert into items(item_image,  item_manufacturing_year, item_Length, item_width, item_weight, item_price, item_description, item_model) VALUES (? , ? , ? , ? , ? , ? , ? , ?)");
    $itemquery->bind_param("bsssssss", $image, $manufacturing_year, $length, $width, $weight, $price, $description, $model);

    $itemquery->execute();
    $itemquery->close();
    $connection->close();
  } 
 }

尝试使用var_dump（）php函数来查看图像名称值是否正确。正如您所做的那样，图像名称可能设置为null。
