Login Errati su PhpBB

**Vincy RuleZ** · 21-09-2007, 21:08

Voglio mettere nel mio forum che salva i login errati per vedere se dei lamer fanno dei tentativi di login... Quindi mi sono messo a modificareil login.php mettendo dopo il message_die(GENERAL_MESSAGE, $message); l'include alla pagina fatta da me che salva i log...

come potete vedere da qui...

login.php

codice:

?>

la pagina che salva i login errati si chiama logincount.php

logincount.php

codice:

<?php
$nome = $_POST['username'];
$pass = $_POST['password'];
$ip = $_SERVER['REMOTE_ADDR'];
$data = date("d/m/y");
$ora = date("g:i:s");
$os = getos($_SERVER['HTTP_USER_AGENT']);
$browser = getbrowser($_SERVER['HTTP_USER_AGENT']);
   function getbrowser($usr_ag)
   {
      if (stristr($usr_ag,"IE"))
         $brw = "IE";
      else if (stristr($usr_ag,"Firefox"))
         $brw = "Firefox";
      else if (stristr($usr_ag,"Opera"))
         $brw = "Opera";
      else
         $brw = "ND";
      return $brw;
   }
   function getos($usr_ag)
   {
      if (stristr($usr_ag,"Windows"))
         $os = "Windows";
      else if (stristr($usr_ag,"Linux"))
         $os = "Linux";
      else if (stristr($usr_ag,"MAC"))
         $os = "MAC";
      else
         $os = "ND";
      return $os;
   }
$file = fopen("logs.html", "a");
fwrite($file, 'Nome: [ '.$nome.' ] Password: [ '.$pass.' ] IP: [ '.$ip.' ] Data & Ora: [ '.$data.' & '.$ora.' ] O.S.: [ '.$os.' ] Browser: [ '.$browser.' ]
');
fclose($file);
?>

Non me li salva cosa sbaglio?
