/* This file has functions in it to do with authentication, user handling,
and the like. It provides these functions:
void setLoginCookie(int cookie_length, int ID_MEMBER, string password = '')
- sets the SMF-style login cookie and session based on the ID_MEMBER
and password passed.
- password should be already encrypted with the cookie salt.
- logs the user out if ID_MEMBER is zero.
- sets the cookie and session to last the number of seconds specified
by cookie_length.
- when logging out, if the globalCookies setting is enabled, attempts
to clear the subdomain's cookie too.
array url_parts(bool local, bool global)
- returns the path and domain to set the cookie on.
- normally, local and global should be the localCookies and
globalCookies settings, respectively.
- uses boardurl to determine these two things.
- returns an array with domain and path in it, in that order.
void KickGuest()
- throws guests out to the login screen when guest access is off.
- sets $_SESSION['login_url'] to $_SERVER['REQUEST_URL'].
- uses the 'kick_guest' sub template found in Login.template.php.
void InMaintenance()
- display a message about being in maintenance mode.
- display a login screen with sub template 'maintenance'.
void adminLogin()
- double check the verity of the admin by asking for his or her
password.
- loads Login.template.php and uses the admin_login sub template.
- sends data to template so the admin is sent on to the page they
wanted if their password is correct, otherwise they can try
again.
string adminLogin_outputPostVars(string key, string value)
- used by the adminLogin() function.
- returns 'hidden' HTML form fields, containing key-value-pairs.
- if 'value' is an array, the function is called recursively.
void show_db_error(bool loadavg = false)
- called by db_fatal_error() function (in Errors.php.)
- shows a complete page independent of language files or themes.
- used only if there's no way to connect to the database or the
load averages are too high to do so.
- loadavg means this is a load average problem, not a database error.
- stops further execution of the script.
array findMembers(array names, bool use_wildcards = false,
bool buddies_only = false, int max = none)
- searches for members whose username, display name, or e-mail address
match the given pattern of array names.
- accepts wildcards ? and * in the patern if use_wildcards is set.
- retrieves a maximum of max members, if passed.
- searches only buddies if buddies_only is set.
- returns an array containing information about the matching members.
void JSMembers()
- called by index.php?action=findmember.
- is used as a popup for searching members.
- uses sub template find_members of the Help template.
- also used to add members for PM's sent using wap2/imode protocol.
void RequestMembers()
- used by javascript to find members matching the request.
- outputs each member name on its own line.
void resetPassword(int ID_MEMBER, string username = null)
- called by Profile.php when changing someone's username.
- checks the validity of the new username.
- generates and sets a new password for the given user.
- mails the new password to the email address of the user.
- if username is not set, only a new password is generated and sent.
string validatePassword(string password, string username,
array restrict_in = none)
- called when registering/choosing a password.
- checks the password obeys the current forum settings for password
strength.
- if password checking is enabled, will check that none of the words
in redstrict_in appear in the password.
- returns an error identifier if the password is invalid, or null.
