Parameters

$type : int: denotes which module that has submitted the entry. This is the current list: 1=tce_db; 2=tce_file; 3=system (eg. sys_history save); 4=modules; 254=Personal settings changed; 255=login / out action: 1=login, 2=logout, 3=failed login (+ errorcode 3), 4=failure_warning_email sent
$action : int: denotes which specific operation that wrote the entry (eg. 'delete', 'upload', 'update' and so on...). Specific for each $type. Also used to trigger update of the interface. (see the log-module for the meaning of each number !!)
$error : int: flag. 0 = message, 1 = error (user problem), 2 = System Error (which should not happen), 3 = security notice (admin)
$details_nr : int: The message number. Specific for each $type and $action. in the future this will make it possible to translate error messages to other languages
$details : string: Default text that follows the message
$data : array<string|int, mixed>: Data that follows the log. Might be used to carry special information. If an array the first 5 entries (0-4) will be sprintf'ed the details-text...
$tablename : string = '': Special field used by tce_main.php. These ($tablename, $recuid, $recpid) holds the reference to the record which the log-entry is about. (Was used in attic status.php to update the interface.)
$recuid : int|string = '': Special field used by tce_main.php. These ($tablename, $recuid, $recpid) holds the reference to the record which the log-entry is about. (Was used in attic status.php to update the interface.)
$recpid : int|string = '': Special field used by tce_main.php. These ($tablename, $recuid, $recpid) holds the reference to the record which the log-entry is about. (Was used in attic status.php to update the interface.)

updatePasswordHashInDatabase()

Method updates a FE/BE user record - in this case a new password string will be set.


    protected
                    updatePasswordHashInDatabase(string $table, int $uid, string $newPassword) : void

Parameters

$table : string: Database table of this user, usually 'be_users' or 'fe_users'
$uid : int: uid of user record that will be updated
$newPassword : string: Field values as key=>value pairs to be updated in database

writeLogMessage()

Writes log message. Destination log depends on the current system mode.


    protected
                    writeLogMessage(string $message, array<int, mixed> ...$params) : void

This function accepts variable number of arguments and can format parameters. The syntax is the same as for sprintf() If a marker ###IP### is present in the message, it is automatically replaced with the REMOTE_ADDR

Parameters

$message : string: Message to output
$params : array<int, mixed>
