My array is blank for some reason?

Alright here are my fucntions, all in line. Should work just perfectly together. The database connections inside of them are correct, infact no errors are printed - I am presented with 100% nothingness.

	/**

	 **/
	function department_array($array, $parent)
	{
		$arr = array();
		for ($i = 0; $i < count($array); $i++)
		{
			if ($array[$i]['dept_parent'] == $parent) {
				$arr[] = $array[$i];
			}
		}
		return $arr;
	}

	$departments = array();
	$q = $this->db->query('SELECT dept_id, dept_name, dept_parent FROM ' . $this->pre . 'departments ORDER BY ' . $sort);

	while ($d = $this->db->nqfetch($q))
	{
		$departments[] = $d;
	}

	return $departments;
}

I've been working on this for nearly two days now, and have rewritten them several times. I am using this as such because I am working with a permission cube and will later incorporate it. This may seem pointless to some to have such functions just to show a department list, but it is very healthy in my opinion for sub categories, and global departments, etc for our nightly reports in our CMS.

Here is how I'm calling it: nqfetch is my custom array function. The only thing I need help with is why this is showing up blank, everything works fine, but the departments in the database are just 'not' showing. {}'s should not be worried about these work, I am simply using them to keep the code from breaking the page. I am calling it like so:

				<form action='to come later' method='post'>
				{$this->table}
				<tr>
				  <td class='header' colspan='2'>Report</td>
				</tr>
				<tr>
				  <td class='tablelight' width='30%'><b>Department?</b></td>
				  <td class='tabledark'>
				    <select name='parent'>
				      <option value='0'>Select One</option>
				      <option value='0'>----------------------------</option>" .
      $this->select_departments($this->department_grab(), $d['dept_parent']) . "
				    </select>
				  </td>
				</tr>
				{$this->etable}
				</form>
