REstrictions for a particular user….

Why not put the kybosh on allowing the “guest user” (aka user_id 376) to save anything at all from the profile page?

<?php
add_action( 'personal_options_update', 'ds_profile_lockout' );
function ds_profile_lockout() {
	global $current_user;
		if( $current_user->ID == '376' )
		wp_die(__('You do not have permission to edit this user.'));
}
?>

Add to mu-plugins.

Alternatively, if the guest user is the only user with role “contributor” remove the edit_user cap from that role.

<?php
 	/*
	Plugin Name: Edit Contributor
	Plugin URI:
	Description: Edits the contributer role
	Author:
	Author URI:
	*/

	$edit_contributor = get_role('contributor');
	$edit_contributor->remove_cap('edit_user');

?>

Add to plugins.

thanks! excellent. So… where is mu-plugins? is that part of a theme? If I make that change is it considered a hack of sorts that I should be concerned about?

mu-plugins will be a folder inside wp-content next to your original plugins folder. Use it for snips of code/plugins you want to run as a “must use”. When you upgrade WP, mu-plugins stays just as it is.

You could give the file a proper plugin header and put into plugins, too. It just makes sense to me to activate it as mu-plugin so users – even the admin – can’t deactivate it easily.

okay – thanks a ton. But what do I call the file? I’ll create an “mu-plugins” folder, then make a file with the text above in it….what do I save it as? anything.php?

ah ha! answered my own question, worked like a charm. THANK YOU!
