I'm using prepopulate to prepopulate a feild of a `node/add/content`. I'm trying to generate a URL using some PHP code that willl generate a URL like:

    http://mysite.com/node/add/content_type?edit[title]={$some_var}

Each of my user profiles will have this link at the top of the page and I would like `$some_var` to hold the username of the user whos profile we are currently viewing. I was wonder how to populate `$some_var` with the username of the user profile being viewed.

Something like:

    $some_var = $username;
    print("<a href=\"http://mysite.com/node/add/content_type?edit[title]={$some_var}\">Content Type</a>");
