/* This file has the hefty job of loading information for the forum. It uses
the following functions:
void reloadSettings()
- loads or reloads the $modSettings array.
- takes care of mysql_set_mode, if set.
- loads any integration settings, SMF_INTEGRATION_SETTINGS, etc.
- optimizes tables based on autoOptDatabase, autoOptLastOpt, and
autoOptMaxOnline.
void loadUserSettings()
- sets up the $user_info array
- assigns $user_info['query_see_board'] for what boards the user can see.
- first checks for cookie or intergration validation.
- uses the current session if no integration function or cookie is found.
- checks password length, if member is activated and the login span isn't over.
- if validation fails for the user, $ID_MEMBER is set to 0.
- updates the last visit time when needed.
void loadBoard()
- sets up the $board_info array for current board information.
- if cache is enabled, the $board_info array is stored in cache.
- is only used when inside a topic or board.
- determines the local moderators for the board.
- adds group id 3 if the user is a local moderator for the board they are in.
- prevents access if user is not in proper group nor a local moderator of the board.
void loadPermissions()
// !!!
array loadMemberData(array members, bool is_name = false, string set = 'normal')
// !!!
bool loadMemberContext(int ID_MEMBER)
// !!!
void loadTheme(int ID_THEME = auto_detect)
// !!!
void loadTemplate(string template_name, bool fatal = true)
- loads a template file with the name template_name from the current,
default, or base theme.
- uses the template_include() function to include the file.
- detects a wrong default theme directory and tries to work around it.
- if fatal is true, dies with an error message if the template cannot
be found.
void loadSubTemplate(string sub_template_name, bool fatal = false)
- loads the sub template specified by sub_template_name, which must be
in an already-loaded template.
- if ?debug is in the query string, shows administrators a marker after
every sub template for debugging purposes.
string loadLanguage(string template_name, string language = default, bool fatal = true)
// !!!
array getBoardParents(int ID_PARENT)
- finds all the parents of ID_PARENT, and that board itself.
- additionally detects the moderators of said boards.
- returns an array of information about the boards found.
string &censorText(string &text)
- censors the passed string.
- if the theme setting allow_no_censored is on, and the theme option
show_no_censored is enabled, does not censor.
- caches the list of censored words to reduce parsing.
void loadJumpTo()
// !!!
void template_include(string filename, bool only_once = false)
- loads the template or language file specified by filename.
- if once is true, only includes the file once (like include_once.)
- uses eval unless disableTemplateEval is enabled.
- outputs a parse error if the file did not exist or contained errors.
- attempts to detect the error and line, and show detailed information.
void loadSession()
// !!!
bool sessionOpen(string session_save_path, string session_name)
bool sessionClose()
bool sessionRead(string session_id)
bool sessionWrite(string session_id, string data)
bool sessionDestroy(string session_id)
bool sessionGC(int max_lifetime)
- implementations of PHP's session API.
- handle the session data in the database (more scalable.)
- use the databaseSession_lifetime setting for garbage collection.
- set by loadSession().
void cache_put_data(string key, mixed value, int ttl = 120)
- puts value in the cache under key for ttl seconds.
- may "miss" so shouldn't be depended on, and may go to any of many
various caching servers.
- supports eAccelerator, Turck MMCache, ZPS, and memcached.
mixed cache_get_data(string key, int ttl = 120)
- gets the value from the cache specified by key, so long as it is not
older than ttl seconds.
- may often "miss", so shouldn't be depended on.
- supports the same as cache_put_data().
void get_memcached_server(int recursion_level = 3)
- used by cache_get_data() and cache_put_data().
- attempts to connect to a random server in the cache_memcached
setting.
- recursively calls itself up to recursion_level times.
