tinyMCE undefined when realpath disabled

IMPORTANT: THIS IS FOR ANYBODY THAT HAS FUNCTION realpath DISABLED BY THE SERVER

I’ve found a way to manage and override the usage of realpath function in order to see the tinyMCE toolbar.

First step:
Edit tiny_mce_gzip.php and just below

@require_once('../../../wp-config.php'); // For get_bloginfo().

add the following code:

// beggining of myRealPath

  function myRealPath($path) {

    // check if path begins with "/" ie. is absolute
    // if it isnt concat with script path
    if (strpos($path,"/") !== 0) {
        $base=dirname($_SERVER['SCRIPT_FILENAME']);
        $path=$base."/".$path;
    }

    // canonicalize
    $path=explode('/', $path);
    $newpath=array();
    for ($i=0; $i<sizeof($path); $i++) {
        if ($path[$i]==='' || $path[$i]==='.') continue;
           if ($path[$i]==='..') {
              array_pop($newpath);
              continue;
        }
        array_push($newpath, $path[$i]);
    }
    $finalpath="/".implode('/', $newpath);

    // check then return valid path or filename
    if (file_exists($finalpath)) {
        return ($finalpath);
    }
    else return FALSE;
}

  // end of myRealPath

Second step:
Edit and replace inside tiny_mce_gzip.php
realpath
into
myRealPath

This should get your tinyMCE toolbar working. Make sure that you have “Use the visual editor when writing” under your profile selected.
