问题描述
我已经建立了数据库，并且我的php表单将图像上传到了我希望它很好的文件夹中.但是，在数据库中它只对图像说空，如果我将其更改为不为空，则会收到一条错误消息: 注意:未定义索引:第45行的C:\ xampp \ htdocs \ sws_blog \ admin \ add_image_post.php中的图像 列图像"不能为空
I have my database set up, and my php form uploads the image to the folder I want it to just fine. However, in the database it just says null for the image, if I change that to not be null, I get an error saying: Notice: Undefined index: image in C:\xampp\htdocs\sws_blog\admin\add_image_post.php on line 45 Column 'image' cannot be null
我正在尝试构建一个自定义PHP博客，仅将其发布/上传到该博客.我有不同的帖子类型，例如图像帖子"和视频帖子".
I am trying to build a custom PHP blog that ONLY I will be posting/uploading to. I have different post types such as "Image Posts" and "Video Posts".
我无法显示我上传图片的那个帖子的图片.
I cannot get the image to show for that post I uploaded the image with..
这是我的add_image_post.php:
Here is my add_image_post.php:

推荐答案
GetSQLValueString($_POST['image'], "text"));
应该是
GetSQLValueString($_FILES['image']['name'], "text"));
也许
And probably
GetSQLValueString($_FILES["image"], "name"));
应该也是
GetSQLValueString($_FILES['image']['name'], "text"));
在switch情况下，您没有name作为$theType.
You don't have name as $theType in your switch cases.
