How to remove Menu settings,Comment settings,Publishing options

The administrator account will always see every option when adding/editing content. If you want to only see certain things then create an account and user roles & permissions to limit what the account can see and do.

Users only see fieldsets for things they have permission to see-- configure permissions correctly at admin/user/permissions and they won't fieldsets they don't have permission for.

For Menu settings

1) select file in path -modules/menu/menu.module in that

2) Goto line 399

3) Add following code

$form['menu']['#attributes']=array
(
'style'=>'display:none',
);

For Revision Information

1) select file in path- modules/node/node.pages.inc in that

2) Goto line 155

3) Add following code

$form['revision_information']['#attributes']=array(
'style'=>'display:none',
);

+1 for formfilter module - perfect for hiding both individual fields and groups of fields from the new/edit node form etc

I think there are often situations where dealing only with permissions will not give you enough control e.g. if you want a user to be able to moderate comments, you give them the "administer comments" permission, but then you get the annoying "comments settings" field group on every new/edit node form. Things like this just add clutter and confusion, especially on content types (e.g. Page) where you know you will never want comments!

EDIT: just found another module, which is even better for me: Node form columns. This also allows you to specify which form objects are expanded or collapsed, but unlike the formfilter module, it only works on the new/edit node form.

the simplest way of solving this problem is by overriding the following function:

node_form($form) (found in node.pages.inc of the node module)

follow these steps:

1- open the template.php of your current enabled theme
2-add the following piece of code:

you can see from this code that we first specify the concerned page by: $_GET['q']=='node/add/page'
which is when creating a new page. u can however specify your own by following the same concept(for example if you want for the blog content u set $_GET['q']=='node/add/blog'))

you can however remove any additional fields by setting them to FALSE (here I just removed the "revision information" and "author").

Thank you ralfph, your solution is great but unfortunatelly it disables also the settings for within the field. Therefor for hiding of those field, I would advice you to use the css method - make from the whole field a special (hiding) class:

$form['#attributes'] = array('class' => 'hide_this_one'); // while pharsing the form - "function phptemplate_node_form($form){}"

Then in css settingsput: .hide_this_one:{ display:none; }
