Remove quicktag buttons but not Visual / Text editor and tabs
I wish to remove the quick-tag buttons in the text (html) editor in TinyMCE but not the html editor itself nor the tabs for choosing between the editors.
When I use
$settings = array('quicktags' = false);
wp_editor($input, 'editor_name', $settings);
Wordpress removes the entire text editor and the Visual / Text tabs for choosing between the editors (as stated in the codex). I have tried
$settings = array('quicktags' = array());
But all buttons remain. Looking through the source code I cannot see a new native remove button code, just add. For backwards compatibility there is listed a edRemoveTag = function(){},
but I cannot find the actual function itself.
I have only found this related thread for quicktags in WP4.0 but it does not seem to cover this issue.
