Check folder permissions before uploading file

[not2bug]

It would be nice if wordpress - or especially the media-upload module would check if its able or has the necessary file permissions to create the upload directory.

It does.

First, let me say - thanks for Wordpress - it's a fantastic tool for folks that don't need to care about HTML and just want to communicate.

I reopened this issue because I feel it describes what I'm seeing even though it was closed/worksforme by someone else.

When specifying the uploads folder as "/wp-content/uploads", WP doesn't gripe at me when there is no such folder on the file system (/wp-content/uploads, not ./wp-content/uploads). There is a folder in the WP tree with that name, but nothing with the absolute path of /wp-content/... If nothing else, I would expect WP to warn me (when configuring it as an admin) that the path I specified doesn't exist yet.

This report was made while using Wordpress 3.2.1 on CentOS 5.6. Wordpress was installed into the virtualhost root directory (not ​http://f.q.d.n/wordpress).

Well in response to the /wp-content versus ./wp-content. I believe wordpress if it were to validate it would validate the path off of ABSPATH, so /wp-content/uploads would work.

This code was able to fix it on line 150 of wp-admin/options.php:

 if ( $option == 'upload_path' && !file_exists(ABSPATH . $value) ) {
        add_settings_error('general', 'path-does-not-exist', __('Media Uploads Folder does not exist.'), 'error');
 } elseif ( $option == 'upload_path' && !is_readable(ABSPATH . $value) ) {
	add_settings_error('general', 'path-not-readable', __('Media Uploads Folder is not readable.'), 'error');
 }
