Question

我用PHP和msqli在我的phpMYadmin上传图片但是得到了提到的错误所以几乎所有东西都会插入除了image.I认为每件事都很好不知道问题在哪里请帮助：（

这是php：

<?php
        if(isset($_POST['submit'])){
        $Name=$_POST['Name'];
        $Desc=$_POST['Desc'];
        $Image=$_FILES['image']['tmp_name']; //get error in this line

        echo $_FILES['image']['error'];//get error in this line


        $sql="INSERT INTO `items`(`Name`,`Description`, `image`) 
        VALUES('$Name','$Desc','$Image')";


        if(mysqli_query($con,$sql)){ 
        echo "new record";
        }
        else{echo"Wrong";}
        mysqli_close($con);
        }
        ?>

html：

<form action="http://localhost/onlinesShop/newitem.php" method="POST" > 
            <table  id='table_admin'>
                <tbody>
                  <tr>
                    <td width="116" height="50" align="left">Name</td>
                    <td width="466"><input name="Name" type="text" id="Name" title="Name" maxlength="200"></td>
                  </tr>
                  <tr>
                    <td height="290">Description</td>
                    <td><textarea name="Desc" cols="40" rows="15" id="textarea"></textarea></td>
                  </tr>
                  <tr>
                    <td>Image</td>
                    <td width="80"><input type="file" name="image" id="fileField" ></td>
                  </tr>
                  <tr>
                    <td>&nbsp;</td>
                    <td><input type="submit" name="submit" id="submit" value="Upload"></td>
                  </tr>
                </tbody>
        </form>
            </table>
        </div>
