Creating a management application for my company and other utility companies... would be nice to remove the Preview button via php without a core hack...

I have to hack the core just a little anyhow and am keeping detailed records but if it is possible not to do this that would be very good.

Any feedback much appreciated

• Are you using the Block Editor or the Classic Editor? The solution will depend on which editor you're supporting. Also, why do you "have" to hack core? – WebElaine Commented Oct 29, 2019 at 19:41
• Because I am creating a project management system for my utility company and there are things that are better done via php than css or js. I am using actions almost everywhere. I think I have 2 hacks on the list. I'll have to look them up and ask here if there is a better solution. I have no worries thought of an update overwriting as I will have updates turned off so I can assess diff's as I need to... definitely trying to avoid it at all costs. – Robert Ruby II Commented Oct 29, 2019 at 23:54

I believe the easiest approach is to hide that Preview button via CSS. Here is a snippet or you can add that style to a pre-existing wp-admin stylesheet that you might have already included.

add_action( 'admin_head-post.php', function(){
  echo '<style>';
    echo '.edit-post-header__settings .editor-post-preview { display: none !important; }';
  echo '</style>';
});

I tried digging through the core and I don't see any way to filter those links out.

Hope that helps!!
