/* 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.
|
|
|
|
array findMembers(array names, bool use_wildcards = false,
|
|
bool buddies_only = false, int max = 500)
|
|
- 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 validateUsername(int memID, string username)
|
|
- checks a username obeys a load of rules. Returns null if fine.
|
|
|
|
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 restrict_in appear in the password.
|
|
- returns an error identifier if the password is invalid, or null.
|
|
|
|
void rebuildModCache()
|
|
- stores some useful information on the current users moderation powers in the session.
