IMCE integration breaks Quick Upload

After disabling and reenabling it seems to work again. I don't know what went wrong here, if you can find it, it would be great, otherwise ignore it.

The problem has also appeared on another site, and it appears to have to do with $Config['QuickUploadAbsolutePath']['Image'] not being set at io.php in function GetResourceTypeDirectory. This causes apache_lookup_uri() to be called in Server_MapPath, and that function returns some voodoo that doesn't work.
The reason that $Config['QuickUploadAbsolutePath']['Image'] is not set is that $Config['UserFilesAbsolutePath'] is not set and the fact that I changed the config such that $Config['QuickUploadAbsolutePath']['Image']= $Config['UserFilesAbsolutePath'], because I do not like those file type based subdirectories.

$Config['UserFilesAbsolutePath'] is not set is that $fck_user_files_path is not set, which relates to $_SESSION['FCKeditor']['UserFilesAbsolutePath'] not being set. This is caused by $_SESSION['FCKeditor']['UserFilesAbsolutePath'] not being set in fckeditor_process_textarea() in fckeditor.module because IMCE is turned on.

In the IMCE specific code of FCKeditor I do not see a reference to the quick upload functionality, so I really wonder if IMCE is involved in quick uploads or not? Is it something I've done wrong? Is it an FCKeditor module bug?

[edit]
Perhaps it is usefull if I mention that my config.php in the php connector still contains the line require_once "../../../../../filemanager.config.php"; and $Config['UserFilesAbsolutePath'] = '' ; just above it.

Yes. That works fine. The things I described above were for the situation in which I had modified the connector config with the include, as is required for non-imce integration. In this case, I left it out, to see what happens. Now I simply get a popup saying that the file uploader is disabled. I can see why:

When IMCE is enabled, Config['LinkUploadURL'] and Config['FlashUploadURL'] are never set. Those values are required for the quick upload forms, and are set when imce is false and $basic_uploads is true. According to the code, IMCE is only used as a replacement of the file browser, not as a replacement of the quick upload functionality. The FCKeditor profile settings should be used for that.

In my opinion the following should be done:
- The settings for quick upload (called basic upload in the admin) should be available all the time, including the directory settings
- Using a drop down the file browser type should be selected, either false, builtin or imce (if available)

I will attach a patch that illustrates my ideas. Don't consider this a full patch: it changes some configuration values so the .install file would also have to be adapted. But it gives an idea what I mean. I think this is much more clear to the end user.

By the way, I see some instances of function_exists('imce_menu') to check for module existence. Why aren't you using module_exists?

The following patch is an updated version and includes a patch for fckeditor.install such that the settings are preserved.

This patch improves the documentation.
