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

[PiroX]

if i add print_r($_POST); to profile.php, then he will bring a site error: "wrong coding of content"

lololol if i change the action to another file like

PHP Code:

<form action="lol.php?do=ptbank" method="post"> 


then he will also NOT go to this file by clicking on submit, if i check the source, then there is the correct code, so i dont get it, it seems that it is blocked somehow oO

ok found the source file of the problem
it is global.php

if i remove "require_once('./global.php');" in my TARGET file, "lol.php", then submit works, hm

the only part with exec_header... is this part in global.php

PHP Code:

// #############################################################################
// Redirect if this forum has a link
// check if this forum is a link to an outside site
if (trim($foruminfo['link']) != '' AND (THIS_SCRIPT != 'subscription' OR $_REQUEST['do'] != 'removesubscription'))
{
    // get permission to view forum
    $_permsgetter_ = 'forumdisplay';
    $forumperms = fetch_permissions($forumid);
    if (!($forumperms & $vbulletin->bf_ugp_forumpermissions['canview']))
    {
        print_no_permission();
    }

    // add session hash to local links if necessary
    if (preg_match('#^([a-z0-9_]+\.php)(\?.*$)?#i', $foruminfo['link'], $match))
    {
        if ($match[2])
        {
            // we have a ?xyz part, put session url at beginning if necessary
            $query_string = preg_replace('/([^a-z0-9])(s|sessionhash)=[a-z0-9]{32}(&|&)?/', '\\1', $match[2]);
            $foruminfo['link'] = $match[1] . '?' . $vbulletin->session->vars['sessionurl_js'] . substr($query_string, 1);
        }
        else
        {
            $foruminfo['link'] .= $vbulletin->session->vars['sessionurl_q'];
        }
    }

    exec_header_redirect($foruminfo['link'], true);
} 


it seems that if (trim($foruminfo['link']) != '' AND (THIS_SCRIPT != 'subscription' OR $_REQUEST['do'] != 'removesubscription')) IS TRUE, that means $foruminfo['link'] is not set, but i dont know what it is or how to set, any idea? or am i totally wrong
