Going after your suggestion, I’ve discovered the function network_admin_url(). I’ll try with that. But here we’re going off topic.

ps. You’re right about the missing closing tags: they are due to my failed attempts to make visible the html :-p

Also, you’re missing the closing (/a) tag in the string, unless the copy/paste ate it. Possible.

I’m coding an option page (and the related option managements code). I would like the whole to be easily translated and ported.

For few specific options I would like to have a dynamic URL in the description. So far I ended up with the following solution (which is part of an array containing the setting of the field).

'info' => sprintf( __( 'Enter your <strong>username</strong> to hide the Settings Page to other Admins. To restore a free access to this page, empty the field here or on the <a href="%s">WP options page under <em>framework_woo_super_user.', 'optimathemes' ), home_url().'/wp-admin/options.php')

Perhaps I could write it better, but the point is, is it a valid solution?

Thanks!
