Displaying Log off link

To display Log off link, e.g. “Welcome username Log off“:

Setup.TS


lib.welcomeLogOff = COA_INT
lib.welcomeLogOff {
 10 = COA
 10 {
  20 = TEXT
  20.typolink.parameter = 1
  20.typolink.returnLast = url
  20.wrap = <form id="logoutform" action="|" method="post">
  25 = TEXT
  25.wrap = Welcome 
  30 = COA
  30 {
   3 = TEXT
   3.data = TSFE:fe_user|user|username
   4 = TEXT
   4.value =  
   5 = TEXT
   5.value = Log off
   5.wrap = <a href="javascript:{}" onclick="document.getElementById('logoutform').submit(); return false;">|
   10 = TEXT
   10.value = <input type="hidden" name="logintype" value="logout" />
   20 = TEXT
   20.value = <input type="hidden" name="redirect_url" value="" />
   30 = TEXT
   30.value = </form>
  }
 }  
}


or simply:

Setup.TS


lib.logout {
 10 = TEXT
 10 {
  value = Logout
  typolink.parameter.data = TSFE:id
  typolink.additionalParams = &logintype=logout
 }
}


this snippet will create link to current page and add “logintype” variable (&logintype=logout) at the end. If you click on this link Typo3 will sign you out.
