trying to make php code work for profile

[Gio~Logist]

a code hellsatan has come up with

PHP Code:

if(!(empty($vboptions['allowedhtmltags']))) {  
  
 $post['fieldx'] = strip_tags($post['fieldx'], $vboptions['allowedhtmltags']);  
  
 } 


now if only we can find out where $post[fieldx] is parsed

here's some php i found in member.php

PHP Code:

// *********************
// CUSTOM PROFILE FIELDS
$profilefields = $DB_site->query("
    SELECT profilefieldid, required, title, type, data, def, height
    FROM " . TABLE_PREFIX . "profilefield
    WHERE form = 0 OR 6 OR 7  OR 8" . iif(!can_moderate(), "
        AND hidden = 0") . "
    ORDER BY displayorder
");


$search = array(
    '#(\r\n|\n|\r)#',
    '#(<br />){3,}#', // Replace 3 or more <br /> with two <br />
);
$replace = array(
    '<br />',
    '<br /><br />',
);

while ($profilefield = $DB_site->fetch_array($profilefields))
{
    exec_switch_bg();
    $profilefieldname = "field$profilefield[profilefieldid]";
    if ($profilefield['type'] == 'checkbox' OR $profilefield['type'] == 'select_multiple')
    {
        $data = unserialize($profilefield['data']);
        foreach ($data AS $key => $val)
        {
            if ($userinfo["$profilefieldname"] & pow(2, $key))
            {
                $profilefield['value'] .= iif($profilefield['value'], ', ') . $val;
            }
        }
    }
    else if ($profilefield['type'] == 'textarea')
    {
        $profilefield['value'] = preg_replace($search, $replace, trim($userinfo["$profilefieldname"]));
    }
    else
    {
        $profilefield['value'] = $userinfo["$profilefieldname"];
    }
    if ($profilefield['value'] != '')
    {
        $show['extrainfo'] = true;
    }
    eval('$customfields .= "' . fetch_template('memberinfo_customfields') . '";');

}
// END CUSTOM PROFILE FIELDS
// ************************* 


is this where the $post[fieldx] isparsed?
