ckEditor上传后不显示照片

如何解决ckEditor上传后不显示照片

我尝试使用ckEditor，并且像往常一样，遇到了ckEditer的新问题，即从PC上传图片，而不是从Web浏览器复制/粘贴图片URL。

但是，经过多次尝试，我成功显示了[浏览]按钮，并且可以将图片上传到服务器[让我们说：它们在Web应用程序下的指定文件夹]。无论如何，现在的问题是ckEditor不会返回新的图片URL。

例如，我在“图片标题”字段中输入路径和图片名称以显示它。

我们将非常感谢您的帮助

下面是我用来上传图片的代码...

<%@ Page Language="VB" Strict="true"%>
<script runat="server">
    Sub Page_Load(ByVal o As Object,ByVal e As EventArgs)

    ' Upload script for CKEditor.
    ' Use at your own risk,no warranty provided. Be careful about who is able to access this file
    ' The upload folder shouldn't be able to upload any kind of script,just in case.
    ' If you're not sure,hire a professional that takes care of adjusting the server configuration as well as this script for you.
    ' (I am not such professional)

    Private Function processUpload() As String
        ' Step 1: change the true for whatever condition you use in your environment to verify that the user
        ' is logged in and is allowed to use the script
        'if (true)
        '    return sendError("You're not allowed to upload files")
        'end If

        ' Step 2: Put here the full absolute path of the folder where you want to save the files:
        ' You must set the proper permissions on that folder
        Dim basePath As String = "C:\\Web Projects\\TextEditors\\upload\\Files\\"

        ' Step 3: Put here the Url that should be used for the upload folder (it the URL to access the folder that you have set in $basePath
        ' you can use a relative url "/images/",or a path including the host "http://example.com/images/"
        ' ALWAYS put the final slash (/)
