Question

我设置了数据库，我的php表单将图像上传到我想要的文件夹就好了。但是，在数据库中它只是对图像说null，如果我将其更改为不为null，我会收到一条错误消息： 注意：未定义的索引：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

我正在尝试构建一个自定义的PHP博客，我只会发布/上传到。我有不同的帖子类型，如“图像帖子”和“视频帖子”。

我无法显示该帖子的图片我上传了图片..

这是我的add_image_post.php：

    <?php require_once('../Connections/blog.php'); ?>

Answer 1

GetSQLValueString($_POST['image'], "text"));

应该是

GetSQLValueString($_FILES['image']['name'], "text"));

可能

GetSQLValueString($_FILES["image"], "name"));

也应该

GetSQLValueString($_FILES['image']['name'], "text"));

name个案例中，您$theType没有switch。

列'image'不能为null
