Notifications of uploads from Frontend Uploader

Are you familiar with WordPress filters? If yes, there’s a fu_after_upload filter

Here’s a sample to place in your functions.php (not tested)

add_action( 'fu_after_upload',  'my_notify_fu_after_upload' );

function my_notify_fu_after_upload( $attachment_ids ) {
    wp_mail( 'admin@example.com', 'new upload', 'somebody uploaded a new file, please moderate' );
}

Depending on your PHP skills you can craft the message as you like.

You’re welcome,

“This field is required” comes from jquery.validate plugin:

Take a look at ./lib/js/frontend-uploader.js, there’s a call for validation plugin, refer to documentation at http://bassistance.de/jquery-plugins/jquery-plugin-validation/ .
You will need to dequeue bundled frontend-uploader.js with
wp_dequeue_script( 'frontend-uploader' ); and then enqueue your custom script.

I’m marking this topic as resolved since the original issue is resolved.

There’s nothing too serious, just read the documentation.
