Hide part of a template from public

<?php if ( !$user_ID ) : ?>
    Hide me
<?php else : ?>
    show me
<?php endif; ?>

You can also use is_admin () function, depending on what you want exactly.

<?php if ( !is_admin() ) : ?>
    Hide me
<?php else : ?>
    show me
<?php endif; ?>

Other possibilities , using current_user_can() function :

if current_user_can( 'edit_posts' )
if current_user_can( 'read_posts' )

and so on.

To explain exactly what I’m trying to do – I have a page with a list of links on it to archived newsletters for the public to download.

I would like there to be a form on this page which allows the administrators to log into a separate site (I have the form code for this bit), but I only want this to be visible to the administrator and editors when they’re logged in. So which approach would be best?

The first solution (using $user_ID) will allow all logged in users (subscribers, administrators, authors, contributors, editors) to use the form.
The second, using is_admin() will allow only administrators to use your form.
So, if you want to allow only the administrators to log into a separate site I think that the second one is better (using is_admin()).

Is there anyway t use the first one but extend the access to editors as well?

Thanks
