ckeditor 文件浏览器

发布于 2024-09-02 00:38:04 字数 103 浏览 5 评论 0原文

我丢失了可以与 ckeditor 集成的免费文件浏览器的链接。它的标题中有数字“4”和.NET，并且是用 PHP 编写的。

有谁知道这个程序的名字吗？

我发现重新发明轮子比弄清楚如何集成 CKFinder 更容易 - 完全有可能是我太厚了。

无论如何，请参阅下面我的代码。它很容易理解并且效果很好。虽然它不允许用户在服务器中导航，但它允许您在调用浏览器时指示从哪个目录提取图像文件。

这都是相当基本的编码，因此它应该适用于所有相对现代的浏览器。

CKeditor 仅打开一个新窗口，其中提供了 URL

/*          
    in CKeditor **use encodeURIComponent()** to add dir param to the filebrowserBrowseUrl property

    Replace "content/images" with directory where your images are housed.
*/          
        CKEDITOR.replace( 'editor1', {  
            filebrowserBrowseUrl: 'browse.php?type=Images&dir=' + encodeURIComponent('content/images'),  
            filebrowserUploadUrl: 'upload.php?type=Files&dir=' + encodeURIComponent('images') 
        });

I found it was easier to re-invent the wheel rather than to figure out how to integrate CKFinder - entirely possible that I'm just too thick.

Any way, see my code below. It's simple to understand and works well. While it does not allow users to navigate around in the server, it does allow you to indicate which directory to pull image files from when calling the browser.

It's all rather basic coding so it should work in all relatively modern browsers.

CKeditor merely opens a new window with the url provided

/*          
    in CKeditor **use encodeURIComponent()** to add dir param to the filebrowserBrowseUrl property

    Replace "content/images" with directory where your images are housed.
*/          
        CKEDITOR.replace( 'editor1', {  
            filebrowserBrowseUrl: 'browse.php?type=Images&dir=' + encodeURIComponent('content/images'),  
            filebrowserUploadUrl: 'upload.php?type=Files&dir=' + encodeURIComponent('images') 
        });
