Chris@76 17 /* This file contains functions that are specifically done by administrators.
Chris@76 18 The most important function in this file for mod makers happens to be the
Chris@76 19 updateSettingsFile() function, but it shouldn't be used often anyway.
Chris@76 20
Chris@76 21 void getServerVersions(array checkFor)
Chris@76 22 - get a list of versions that are currently installed on the server.
Chris@76 23
Chris@76 24 void getFileVersions(array versionOptions)
Chris@76 25 - get detailed version information about the physical SMF files on the
Chris@76 26 server.
Chris@76 27 - the input parameter allows to set whether to include SSI.php and
Chris@76 28 whether the results should be sorted.
Chris@76 29 - returns an array containing information on source files, templates
Chris@76 30 and language files found in the default theme directory (grouped by
Chris@76 31 language).
Chris@76 32
Chris@76 33 void updateSettingsFile(array config_vars)
Chris@76 34 - updates the Settings.php file with the changes in config_vars.
Chris@76 35 - expects config_vars to be an associative array, with the keys as the
Chris@76 36 variable names in Settings.php, and the values the varaible values.
Chris@76 37 - does not escape or quote values.
Chris@76 38 - preserves case, formatting, and additional options in file.
Chris@76 39 - writes nothing if the resulting file would be less than 10 lines
Chris@76 40 in length (sanity check for read lock.)
Chris@76 41
Chris@76 42 void updateAdminPreferences()
Chris@76 43 - saves the admins current preferences to the database.
Chris@76 44
Chris@76 45 void emailAdmins(string $template, array $replacements = array(), additional_recipients = array())
Chris@76 46 - loads all users who are admins or have the admin forum permission.
Chris@76 47 - uses the email template and replacements passed in the parameters.
Chris@76 48 - sends them an email.
Chris@76 49
Chris@76 50 bool updateLastDatabaseError()
Chris@76 51 - attempts to use the backup file first, to store the last database error
Chris@76 52 - and only update Settings.php if the first was successful.
