t3lib_userAuth::setBeUserByUid (  $  uid  ) 
 

Raw initialization of the be_user with uid=$uid This will circumvent all login procedures and select a be_users record from the database and set the content of ->user to the record selected. Thus the BE_USER object will appear like if a user was authenticated - however without a session id and the fields from the session table of course. Will check the users for disabled, start/endtime, etc. ($this->user_where_clause())

Parameters:
integer The UID of the backend user to set in ->user
Returns:
void

type. Also used to trigger update of the interface. (see the log-module for the meaning of each number !!)

integer 
details_nr
The message number. Specific for each
type and $action. in the future this will make it possible to translate errormessages to other languages
string $details: Default text that follows the message
array $data: 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...

t3lib_userAuth::writeUC (  $  variable = ''  ) 
 

This writes $variable to the user-record. This is a way of providing session-data. You can fetch the data again through $this->uc in this class! If $variable is not an array, $this->uc is saved!

Parameters:
