Chris@76	17 /* This file has the hefty job of loading information for the forum. It uses
Chris@76	18 the following functions:
Chris@76	19
Chris@76	20 void reloadSettings()
Chris@76	21 - loads or reloads the $modSettings array.
Chris@76	22 - loads any integration settings, SMF_INTEGRATION_SETTINGS, etc.
Chris@76	23
Chris@76	24 void loadUserSettings()
Chris@76	25 - sets up the $user_info array
Chris@76	26 - assigns $user_info['query_wanna_see_board'] for what boards the user can see.
Chris@76	27 - first checks for cookie or intergration validation.
Chris@76	28 - uses the current session if no integration function or cookie is found.
Chris@76	29 - checks password length, if member is activated and the login span isn't over.
Chris@76	30 - if validation fails for the user, $id_member is set to 0.
Chris@76	31 - updates the last visit time when needed.
Chris@76	32
Chris@76	33 void loadBoard()
Chris@76	34 - sets up the $board_info array for current board information.
Chris@76	35 - if cache is enabled, the $board_info array is stored in cache.
Chris@76	36 - redirects to appropriate post if only message id is requested.
Chris@76	37 - is only used when inside a topic or board.
Chris@76	38 - determines the local moderators for the board.
Chris@76	39 - adds group id 3 if the user is a local moderator for the board they are in.
Chris@76	40 - prevents access if user is not in proper group nor a local moderator of the board.
Chris@76	41
Chris@76	42 void loadPermissions()
Chris@76	43 // !!!
Chris@76	44
Chris@76	45 array loadMemberData(array members, bool is_name = false, string set = 'normal')
Chris@76	46 // !!!
Chris@76	47
Chris@76	48 bool loadMemberContext(int id_member)
Chris@76	49 // !!!
Chris@76	50
Chris@76	51 void loadTheme(int id_theme = auto_detect)
Chris@76	52 // !!!
Chris@76	53
Chris@76	54 void loadTemplate(string template_name, array style_sheets = array(), bool fatal = true)
Chris@76	55 - loads a template file with the name template_name from the current,
Chris@76	56 default, or base theme.
Chris@76	57 - uses the template_include() function to include the file.
Chris@76	58 - detects a wrong default theme directory and tries to work around it.
Chris@76	59 - if fatal is true, dies with an error message if the template cannot
Chris@76	60 be found.
Chris@76	61
Chris@76	62 void loadSubTemplate(string sub_template_name, bool fatal = false)
Chris@76	63 - loads the sub template specified by sub_template_name, which must be
Chris@76	64 in an already-loaded template.
Chris@76	65 - if ?debug is in the query string, shows administrators a marker after
Chris@76	66 every sub template for debugging purposes.
Chris@76	67
Chris@76	68 string loadLanguage(string template_name, string language = default, bool fatal = true, bool force_reload = false)
Chris@76	69 // !!!
Chris@76	70
Chris@76	71 array getBoardParents(int id_parent)
Chris@76	72 - finds all the parents of id_parent, and that board itself.
Chris@76	73 - additionally detects the moderators of said boards.
Chris@76	74 - returns an array of information about the boards found.
Chris@76	75
Chris@76	76 string &censorText(string &text, bool force = false)
Chris@76	77 - censors the passed string.
Chris@76	78 - if the theme setting allow_no_censored is on, and the theme option
Chris@76	79 show_no_censored is enabled, does not censor - unless force is set.
Chris@76	80 - caches the list of censored words to reduce parsing.
Chris@76	81
Chris@76	82 void template_include(string filename, bool only_once = false)
Chris@76	83 - loads the template or language file specified by filename.
Chris@76	84 - if once is true, only includes the file once (like include_once.)
Chris@76	85 - uses eval unless disableTemplateEval is enabled.
Chris@76	86 - outputs a parse error if the file did not exist or contained errors.
Chris@76	87 - attempts to detect the error and line, and show detailed information.
Chris@76	88
Chris@76	89 void loadSession()
Chris@76	90 // !!!
Chris@76	91
Chris@76	92 void loadDatabase()
Chris@76	93 - takes care of mysql_set_mode, if set.
Chris@76	94 // !!!
Chris@76	95
Chris@76	96 bool sessionOpen(string session_save_path, string session_name)
Chris@76	97 bool sessionClose()
Chris@76	98 bool sessionRead(string session_id)
Chris@76	99 bool sessionWrite(string session_id, string data)
Chris@76	100 bool sessionDestroy(string session_id)
Chris@76	101 bool sessionGC(int max_lifetime)
Chris@76	102 - implementations of PHP's session API.
Chris@76	103 - handle the session data in the database (more scalable.)
Chris@76	104 - use the databaseSession_lifetime setting for garbage collection.
Chris@76	105 - set by loadSession().
Chris@76	106
Chris@76	107 void cache_put_data(string key, mixed value, int ttl = 120)
Chris@76	108 - puts value in the cache under key for ttl seconds.
Chris@76	109 - may "miss" so shouldn't be depended on, and may go to any of many
Chris@76	110 various caching servers.
Chris@76	111 - supports eAccelerator, Turck MMCache, ZPS, and memcached.
Chris@76	112
Chris@76	113 mixed cache_get_data(string key, int ttl = 120)
Chris@76	114 - gets the value from the cache specified by key, so long as it is not
Chris@76	115 older than ttl seconds.
Chris@76	116 - may often "miss", so shouldn't be depended on.
Chris@76	117 - supports the same as cache_put_data().
Chris@76	118
Chris@76	119 void get_memcached_server(int recursion_level = 3)
Chris@76	120 - used by cache_get_data() and cache_put_data().
Chris@76	121 - attempts to connect to a random server in the cache_memcached
Chris@76	122 setting.
Chris@76	123 - recursively calls itself up to recursion_level times.
