Translate role names in your WordPress plugin or theme

I've been working on a plugin that needs to print a list of all role names with a checkbox next to them. But when you get the printable role name from $wp_roles->roles[$x]['name'], you only get the English name. The translation isn't stored anywhere in $wp_roles. Also, since it's a variable, you can't use one of the basic gettext functions like __() or _e() to have someone provide translations for you (although even if you could, that would be a dirty way of doing it).

To get the translated role names that are already included in WordPress, use translate_user_role() on that full English name rather than translate_with_context().

I don't know why it's virtually undocumented, so it's possible there's a negative to doing it this way, but that's actually the function used by core to get the translated dropdown menu.

“Error Saving Media Attachment”

I recently had a client trying to upload a file in WordPress, but each time WordPress would display "Error Saving Media Attachment."  I knew that permissions on the upload folder had been set properly since other files were uploading fine.  Then I noticed that it was a Word document, and all the other uploaded files were images or PDFs.

It turns out that WordPress only allows uploading certain filetypes, and .doc files weren't in the list.  If you're using WordPress Multi-user, it might be as simple as going to Network Admin, then Settings -> Network Settings and change the "Upload file types".

If you're still having problems,  just add something like this to your functions.php:

function add_upload_mimes ($mimes=array()) {
    $mimes['docx']='text/plain'; // add your file extension, such as docx
    return $mimes;
}
add_filter("upload_mimes","add_upload_mimes");

Or, if you're too lazy for that, try out the PJW Mime Config plugin.
