modified profile.php does not recognize custom $_POST['do'] == "xx"

[PiroX]

yes i edited the profile.php
i just put it above

// ############################### start dst autodetect switch ###############################
if ($_POST['do'] == 'dst')
{

stil not working with your tip
also tried to switch the conditions

//edit (using vbulletin v3.8.3)
if i remove

<input type="hidden" name="s" value="$session[sessionhash]" />
<input type="hidden" name="securitytoken" value="$bbuserinfo[securitytoken]" />

but i dont want to disable that security

if there is no other options expect of disabling CSRF_PROTECTION, can anyone tell me the command


it must be something with the security token, if i remove it, then it will display "profile.php?do=ptbank" (in url list or what it is called ) but brings that error
if the input with security token is there, then he wont do anything expect of reloading the same site "profile.php?do=bank"
