Checkbox til array

Jeg har et problem med at overføre data fra checkboxe til arrays.

Jeg opstiller følgende:

$strSQLYears = "SELECT * FROM kontingent_years ORDER BY year";
$resYears = mysql_query($strSQLYears);

while ($rowYears = mysql_fetch_assoc($resYears))
{
  echo "<td class=TDCenter><input class=checkbox type=checkbox name=\"".$rowYears['year']."[]\" value=\"".$row['member_id']."\"";

  $strSQLPaid = "SELECT * FROM kontingent_year_combi WHERE year = '".$rowYears['year']."' AND member_id ='".$row['member_id']."'";
  $resPaid = mysql_query($strSQLPaid);

  if (mysql_num_rows($resPaid) == "1")
  {
    echo " checked></td>";
  }
  else
  {
    echo " ></td>";
  }
}

hvilket virker fint.

I modtagerenden forsøger jeg med:

foreach ($_POST as $felt)
{
  echo $felt;
  for ( $i = 0; $i < count($felt); $i=$i+1 )
  {
    $strSQL1 = "SELECT * FROM kontingent_year_combi WHERE member_id = '".$felt[$i]."' AND year = '".$felt."'";
    $res1 = mysql_query($strSQL1);

    if ( mysql_num_rows($res1) == 0 )
    {
      $strSQLInsert = "INSERT INTO kontingent_year_combi (year, member_id) VALUES ('".$felt."', '".$felt[$i]."')";
      $resInsert = mysql_query($strSQLInsert);
    }
  }

  $strNotIn = "";
  for ( $i = 0; $i < count($felt); $i=$i+1 )
  {
    $strNotIn = $strNotIn."'".$felt[$i]."', ";
  }
  $strNotIn = substr($strNotIn, 0, strlen($strNotIn) - 2);
}

$strSQLNotIn = "SELECT member_id FROM members WHERE member_id NOT IN (".$strNotIn.")";
$resNotIn = mysql_query( $strSQLNotIn );

while ($rowNotIn = mysql_fetch_assoc($resNotIn))
{
  $strSQL2 = "SELECT * FROM kontingent_year_combi WHERE member_id = '".trim($rowNotIn['member_id'])."' AND year = '".$felt."'";
  $res2 = mysql_query($strSQL2);
     
  if (mysql_num_rows($res2) > 0)
  {
    $strSQL3 = "DELETE FROM kontingent_year_combi WHERE member_id = '".trim($rowNotIn['member_id'])."' AND year = '".$felt."'";
    //$res3 = mysql_query($strSQL3);
    echo $strSQL3;
  }
}

Hvis jeg prøver med echo $felt får jeg 'Array'
