The details for an authenticated visitor are:
- id_auteur: the unique internal author number
 - nom: the author’s signature name
 - bio: the author’s short biography
 - email: the author’s email address
 - nom_site: the author’s Internet site name/title
 - url_site: the author’s Internet site HTTP address
 - login: the login identifier
 -  statut:
- 0minirezo (for administrators and restricted administrators),
 - 1comite (editors),
 - 6forum (visitors)
 
 - webmestre : ’oui’ if the author is declared as webmaster
 - maj: the date and time of the last modification to the author’s personal data (any modification to the author data contained in spip_auteurs such as the last connection date/time, last internal message sent, list update to the personal details file...)
 - pgp: the author’s public PGP key
 - en_ligne: the date and time of last connection (not the current one)
 - imessage: ’oui’ if the author has sent a private message
 - messagerie:
 -  prefs: the list of author preferences (basically how the private space displays, if a cookie is to be remembered...)
- couleur => 1 to 6, colour code for the private space
 - display => 1 (text only) ; 2 (icons and text) ; 3 (icons only)
 - cnx => empty or ’perma’ (if "connected several days" has been checked)
 
 - cookie_oubli: hash of the replacement cookie sent of forgotten, otherwise empty
 - source: ’spip’ or ’ldap’
 - lang: language used in the private space
 - extra: list of extra fields declared for the author
 - auth: type of authentication used (spip, ldap)
 - cookie: ’oui’ if connected with a cookie - non-existent if connected otherwise (incl. PHP_AUTH_USER)
 - hash_env: internal (hash) code identifying the visitor session uniquely
 - ip_change: FALSE so long as the connected IP doesn’t change. TRUE if the connected IP changes. SPIP then recreates a new session for the connected user (with ip_change set to FALSE); this new session disconnects any possible cookie thief.
 
To display one of these details if and only if the visitor is an administrator:
[(#SESSION{statut}|=={0minirezo}|oui)  You are one of the administrators, maybe restricted, maybe not]
In the same fashion, you can restrict the display of a field depending on the visitor’s status:
[(#SESSION{statut}|=={0minirezo}|oui)  #DESCRIPTIF]
You can complicate the case further still, by loading a template called  reserved.html :
[(#SESSION{statut}|=={0minirezo}|oui)  <INCLURE{fond=reserved, env}>]
