Is there a way to tell WordPress not to list certain files of my plugin in the Plugins -> Editor screen?

  • I'm not exactly sure what the plugin editor is. I have an Appearance -> Editor, but no Plugins -> Editor. – Howdy_McGee Mar 21 '14 at 16:45
  • There is a Plugins -> Editor on 3.9-alpha, at least. I can't check other recent releases right now. – s_ha_dum Mar 21 '14 at 17:04
  • I think it's been there for a very long time I always use it to fix certain problems in PHP for customers when I don't have FTP access just wp-admin. But it shows files that shouldn't be edited, ever - it's just clutter to list there. Appearance -> Editor is the theme editor by the way. – Firsh - LetsWP.io Mar 22 '14 at 19:06

Ok I figured it out, there is just one filter hook in the wp-admin/plugin-editor.php that can be useful but it's enough (otherwise one would probably need to mess with the output buffer).

    add_filter('editable_extensions', array($this, 'my_editable_extensions'));

and then

function my_editable_extensions($editable_extensions){
    if(empty($_POST['plugin']) || (!empty($_POST['plugin']) && $_POST['plugin'] !== "plugin-name/plugin-name.php"){
        return $editable_extensions;
        return array_diff($editable_extensions, array('txt', 'html'));

Note: wp_reset_vars() is called so the only way to know which plugin's files are being edited is from the $_POST.
