How to hide or Disable Custom Field

I have added a custom field called tax.

It has a default value.

What I want is the it should not
be edited either by the admin or
the user in the Edit User Form.
( Because it is one for all )

It has a default value which can
be edited in the add fields page only

But it should be visible in the
Edit User Form but cannot be edited.

There are some fields in the Edit User form
which needs to be filled only by admin.

So by any chance or by mistake the
admin should not edit that particular
field because that field is used for tax
calculation only any changed to this
field will affect the required result.

It field should only be seen but not
edited by the admin in the user edit
form, as it has a default value asigned
to it. If admin needs to change, it can only
be done through the add field page.

I hope you understood the problem.

You can disable it from editing by using javascript.
Or else you could hide it with CSS by using rules like:

Code:

FORM INPUT[name="name_f"]
{
	visibility: hidden;
}

This seems not working.

What is needed is
When we add the field there are options
under visibility of the field, but that is
only for the user profile, not for the admin.

Can we have one more option
Display in Edit User form? ( in admin area >> add field )

Don't Display
Display and allow editing
Display only, editing is not allowed

Of course it's not working if you just copy-pasted the code
You've to adjust it to your situation (read field name) and add it to the site.css file/

From Quote : If this field can't be edited by admin and by user,

From Quote : I guess it will have the same value for all users correct?
Then how you will use it?

From Quote : Will it just be displayed for user and admin?

> > Yes it will only be displayed for the user and also for the admin in the Edit User page
( But can be edited by the admin in the Additional Fields page,the default value )


From Quote : if yes I believe just templates modification will be enough in this situation.

> > what template modification has to be done?

As I tried to find out, where to find the additional fields, have no clue as to where to find them in the code, and in which template

And if css is used then I think logically that, it will also affect in the Additional Field page, in the admin area. Where the default values are supposed to be edited but also should only be seen in the Edit User page, correct me if I am wrong.


The situation with pictures




In the Edit User page when
the admin browse for the member
he sees this page




What I want is this
( The Tax area has been manupilated
in photoshop to show the effect which
is to be needed )




And this is what the user sees






I hope this pictures have made the situiation more clear.
