PM Wiki Integration With Icy Phoenix
-----------------------------------
Hi Guys

I am trying to incorporate pmWiki to my website and have it editable by the members of my site.

In pmwiki cookbook is many scripts to interface it into phpbb2, phpbb3 smf etc etc but not one for ICY. 

What i have here is the PHPbb2 script , can someone please help modify it so that it may work for ICY if you know what i mean.

pmwiki resides at the same level as my forum folder ie in the root.

[code linenumbers=false]

<?php if (!defined('PmWiki')) exit();

##
## SMC: New alternative Wiki Auth
## SMC: Check if we are already authenticated via phpBB2 forum
## Version: 1.0
##

// Set the default phpBB2 cookie name.  _data is appended to this name later in this script.
SDV($phpBB2cookie,'phpBB2_cookie_name');

// Override the default AuthFunction to phpAuth
$AuthFunction = 'PhpBB2Auth';

  $m_phpBB2_auth = false;
  $m_username = 'Anonymous';  // forum defaults to this also

  $m_data_cookie = $phpBB2cookie . '_data';  // append _data to cookie name as this is the element we need
  #print "Session Cookie: " . $m_data_cookie . "<br>";

	if (isset($_COOKIE[$m_data_cookie]))
	{
        $sessiondata = isset($_COOKIE[$m_data_cookie]) ? unserialize(stripslashes($_COOKIE[$m_data_cookie])) : array();
        if (strcasecmp((string)$sessiondata['username'],"Anonymous") <> 0) {
            $m_phpBB2_auth = true;
            $Author = (string)$sessiondata['username'];
		    #print "Session Data: " . (string)$sessiondata['username'] . "<br>";
        }
	}

function PhpBB2Auth($pagename, $level, $authprompt=true, $since=0) {
  global $DefaultPasswords, $GroupAttributesFmt, $AllowPassword,
    $AuthCascade, $FmtV, $AuthPromptFmt, $PageStartFmt, $PageEndFmt,
    $AuthId, $AuthList, $NoHTMLCache, $m_phpBB2_auth;

  if (!$authprompt) return false;

    if ($k == 'authpw' || $k == 'authid') continue;
    $v = str_replace('$', '$',
             htmlspecialchars(stripmagic($v), ENT_COMPAT));
    $postvars .= "<input type='hidden' name='$k' value=\"$v\" />\n";
  }
  $FmtV['$PostVars'] = $postvars;
  SDV($AuthPromptFmt,array(&$PageStartFmt,
    "<p><b>$[Password required]</b></p>
      <form name='authform' action='{$_SERVER['REQUEST_URI']}' method='post'>
        $[Password]: <input tabindex='1' type='password' name='authpw'
          value='' />
        <input type='submit' value='OK' />\$PostVars</form>
        <script language='javascript' type='text/javascript'><!--
          document.authform.authpw.focus() //--></script>", &$PageEndFmt));
  PrintFmt($pagename,$AuthPromptFmt);
  exit;
[/code]

I hope someone can help, its been pulling my hair out for weeks.
