Normal PHP to Codeigniter

You need to fetch your results as an array with result_array() instead of result() as the paser want's an array and not an object.

PHP Code:

$alimente = $this->db->query('select name as aliment from alimente')->result_array();
$content = $this->parser->parse('alergeni_alimente/list', array('ALIMENTE' => $alimente), true);

{ALIMENTE}
<tr>
    <td>{aliment}</td>

    <td></td>
</tr>
{/ALIMENTE}
