retrieve data (query) problem smarty

Hi,

I recently installed 'collabtive' (project management script in some sort of mvc with smarty engine).
Although it is my first time using the smarty engine I kind of managed to retrieve some data from my database.

One problem though:
I only get the amount of data from the database but with no text or what so ever.
To be more exact, I have 7 rows in mysql, and also get them on my page, but they are just empty rows.

The code itself is kind of long, but I still hope you guys could help me.


EDIT: don't mind the tools column, I still have to fix that

function getportfolio($id)
    {
        $id = (int) $id;

        $sel = mysql_query("SELECT * FROM portfolio WHERE ID = $id LIMIT 1");
      $portfolio = mysql_fetch_array($sel,MYSQL_ASSOC);
      
        if (!empty($portfolio))
        {
         $portfolio["id"] = stripslashes($portfolio["id"]);
         $portfolio["name"] = stripslashes($portfolio["name"]);
            $portfolio["description"] = stripslashes($portfolio["description"]);
            return $portfolio;
        }
        else
        {
            return false;
        }
    }
    function getportfolios()
    {
        $category = mysql_real_escape_string($category);

        $portfolios = array();
        $sel1 = mysql_query("SELECT id, name, description FROM portfolio");

        while ($portfolio = mysql_fetch_array($sel1))
        {
            $theportfolio = $this->getportfolio($portfolio["ID"]);
            array_push($portfolios, $theportfolio);
        }

        if (!empty($portfolios))
        {
            return $portfolios;
        }
        else
