Link is not working for embed mode for non-clean_urls Drupal set up

Tested in the discussion forum. http://drupal.org/node/217369#comment-2338680

In phpbbforum.module

Add this inside _phpbbforum_set_globals()

  global $_v_site_forum_url;
  // Vorapoap
  $clean_url = variable_get("clean_urls", 0);
  $site_forum_url = $base_url .'/'. $site_phpbb_page;
  if ($clean_url == 0) {
          $vpatterns = array('/\//', '/\^/', '/\./', '/\$/', '/\|/',
'/\(/', '/\)/', '/\[/', '/\]/', '/\*/', '/\+/',
'/\?/', '/\{/', '/\}/', '/\,/');
        $vreplace = array('\/', '\^', '\.', '\$', '\|', '\(', '\)',
'\[', '\]', '\*', '\+', '\?', '\{', '\}', '\,');

        $_v_site_forum_url = array(
            preg_replace($vpatterns, $vreplace, $site_forum_url.'/'),
             $base_url .'/index.php?q='. $site_phpbb_page
        );
  }
  // \Vorapoap

In phpbbforum.pages.inc

Add this function

//Vorapoap
function _v_phpbbforum_replace_url($output) {
    global $_v_site_forum_url;
    //http://xx.xx.com/phpbbforum/xxx.php?
    return preg_replace('/'.$_v_site_forum_url[0].'(\w+)\.php\??/', $_v_site_forum_url[1].'/$1.php&', $output);
}
//\Vorapoap

And modify below functions

function _phpbbforum_replace_block_links($output) {
  $output = _phpbbforum_replace_forum_url($output);
  $output = _phpbbforum_restore_block_links($output);
  //Vorapoap
  if (!empty($GLOBALS['_v_site_forum_url'])) {
      $output = _v_phpbbforum_replace_url($output);
  }
  //\Vorapoap

  return $output;
}

function _phpbbforum_replace_block_links($output) {
  $output = _phpbbforum_replace_forum_url($output);
  $output = _phpbbforum_restore_block_links($output);
  //Vorapoap
  if (!empty($GLOBALS['_v_site_forum_url'])) {
      $output = _v_phpbbforum_replace_url($output);
  }
  //\Vorapoap

  return $output;
}

Next is the fix for "search"

You have to modify phpBB3/styles/...../templates/search_body.html

And put this

<input type="hidden" name="q" value="phpbbforum/search.php" />

You may have a better way to add this code for clean_url version.

Optional Fix

For people want to redirect all non-Drupal page to Drupal page only.

I added this at very top of phpBB3/common.php

//Vorapoap (Hacked (top of /phpBB3/common.php))
if (!defined("ADMIN_START") && !defined("IN_PHPBB_AJAX") && !defined("IN_PHPBB_NO_EMBED")) {
    // Not in Drupal embedded page?
    if ($_SERVER['PHP_SELF'] != '/index.php') {
        $s = $_SERVER['REQUEST_URI'];
        $s = str_replace(array('/phpBB3/','.php?'), array('','.php&'), $s);
        header("Location: http://".$_SERVER['HTTP_HOST'].'/index.php?q=phpbbforum/'.$s);
        exit();
    }
}
//\Vorapoap
