I\'m using wordpress as a content manager or something, so i\'m using backend only (and i\'ve disabled the frontend with a ghost theme which redirect to the admin panel).

The question is: how could i disable the "view" post button and generally every mention to "preview" posts, view categoryes, pages etc?

Solved!

Thank you cristian.raiber! It worked perfectly. I\'ve also put this lines to hide the previews in single posts:

function posttype_admin_css() {
global $post_type;
$post_types = array(
                        /* set post types */ 
                        \'progetti\',
                        \'post\',
                        \'page\',
                  );
    if(in_array($post_type, $post_types))
    echo \'#post-preview, #view-post-btn{display: none;}\';
}
add_action( \'admin_head-post-new.php\', \'posttype_admin_css\' );
add_action( \'admin_head-post.php\', \'posttype_admin_css\' );


add_action(\'admin_head\', \'hide_quick_view\');

function hide_quick_view() {
  echo \'
    span.view {display: none !important; visibility: hidden !important; opacity: 0 !important;}
  \';
}
