ช่วยด้วยครับใช้ checkbox เพิ่มและลบข้อมูลแบบหลายๆ record

mysql_select_db($database_localhost, $localhost);
$query_action = "SELECT member.*,action.*  FROM action,member where member.id_m = action.id_member and action.id_member = '".$_POST["id_member$i"]."' and action.id_folder = '".$_POST["id_folder$i"]."' and action.status_action = '".$_POST["status$i"]."' and action.id_a = '".$_POST["status$i"]."'"; 
$action = mysql_query($query_action, $localhost) or die(mysql_error());
$row_member = mysql_fetch_assoc($action);
$totalRows_action = mysql_num_rows($action);

	echo $totalRows_action;
	echo $query_action;
	for($i=0;$i<=$totalRows_member;$i++)
	{ 
	
		if(($totalRows_action<0)and($_POST["status$i"] != ""))
		{
			$strSQL = "INSERT INTO action ";
			$strSQL .="(id_member,id_folder,status_action,id_a) ";
			$strSQL .="VALUES ";
			$strSQL .="('".$_POST["id_member$i"]."','".$_POST["id_folder$i"]."', ";
			$strSQL .="'".$_POST["status$i"]."','".$_POST["id_a"]."') ";

		mysql_select_db($database_localhost, $localhost);	
  $Result1 = mysql_query($strSQL, $localhost) or die(mysql_error());
		
		}else if($_POST["status$i"] != 1)  {

	// ลบ$row_member['id_a']
	   $strSQL = "DELETE FROM action ";
 	  $strSQL .="WHERE id_a = '".$_POST["id_a"]."' ";
 	 mysql_select_db($database_localhost, $localhost);
 	 $Result1 = mysql_query($deleteSQL, $localhost) or die(mysql_error());

}
}
