In reply to Rilwis.

Can you please provide some resources on Herbert beside its documentation , I am unable to create a section using it.
using this inside a function :-
add_settings_field(
'authenticationCode',
'Authentication Code',
array( $this, 'authenticationCodeCallback' ),
'analyticaAuthenticationSetting',
'authenticationSection'
); or

add_settings_field(
'authenticationCode',
'Authentication Code',
array( __CLASS__, 'authenticationCodeCallback' ),
'analyticaAuthenticationSetting',
'authenticationSection'
);

in both case callback function is not called :( .
