<?php


function clean($var)
{
$var=trim(mysql_real_escape_string(strip_tags($var)));
$var=htmlspecialchars($var,ENT_QUOTES);
$var=preg_replace("/n","<br>",$var);

return filter_var($var,FILTER_SANITIZE_STRING);
}

echo clean(recaptcha_get_html($publickey, $error));

?>

 

Should be:

<?php
echo clean(recaptcha_get_html($publickey, $error));?>

Try:

 

<?php


function clean($var)
{
$var=trim(mysql_real_escape_string(strip_tags($var)));
$var=htmlspecialchars($var,ENT_QUOTES);
$var=preg_replace("/n","<br>",$var);

return filter_var($var,FILTER_SANITIZE_STRING);
}

echo clean(recaptcha_get_html($publickey, $error));

?>

ill check that later (again)

it didnt do any difference, but ill have to double check the coding to make sure its correct

 

and ill  go back to a error free code and build from there and see if i can produce it free of errors

based on what youve written

so, thanks and c you later

only thing i can think of is filter_var() is a PHP5 function so if you run PHP4 it wont work properly ;)

in which case you would need :

 

<?php
session_start();
if (!isset($_SESSION['user'])) { header("Location: index.php"); }
//------------------------------------------------------------------------ANTI-XSS FUNCTION------------------------------
function RemXSS($val) {
   // remove all non-printable characters. CR(0a) and LF(0b) and TAB(9) are allowed
   // this prevents some character re-spacing such as <java\0script>
   // note that you have to handle splits with \n, \r, and \t later since they *are* allowed in some inputs
   $val = preg_replace('/([\x00-\x08,\x0b-\x0c,\x0e-\x19])/', '', $val);

   // straight replacements, the user should never need these since they're normal characters
   // this prevents like <IMG SRC=&#38;#X40&#38;#X61&#38;#X76&#38;#X61&#38;#X73&#38;#X63&#38;#X72&#38;#X69&#38;#X70&#38;#X74&#38;#X3A&#38;#X61&#38;#X6C&#38;#X65&#38;#X72&#38;#X74&#38;#X28&#38;#X27&#38;#X58&#38;#X53&#38;#X53&#38;#X27&#38;#X29>
   $search = 'abcdefghijklmnopqrstuvwxyz';
   $search .= 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
   $search .= '1234567890!@#$%^&*()';
   $search .= '~`";:?+/={}[]-_|\'\\';
   for ($i = 0; $i < strlen($search); $i++) {
      // ;? matches the ;, which is optional
