Upload only for logged in users?

Yep, I’ve put together a little code snippet you can follow:

add_action( 'init', 'wpfx_hide_logged_out' );
function wpfx_hide_logged_out() {

	if ( ! is_user_logged_in() ) {
		add_shortcode( 'fu-upload-form', 'wpfx_logged_out_message' );
	}
}
function wpfx_logged_out_message() {
	return '<div id="ugc-media-logged-out">You must be logged in to submit a post.</div>';
}

Hope this helps.

Thanks Daniel!

Where would one add this?

Update, couple minutes later: Oh, I got it, you add it to the functions.php
Just in case anyone else was wondering…
Works great, thank you!
