我使用下表管理机构的来信与采取的行动
letter_branch
+-----------+-------------+
| branch_id | branch_name |
+-----------+-------------+
| 1 | Admin |
| 2 | Accounts |
| 3 | Engineering |
| 4 | Health |
+-----------+-------------+
letter_letter
+-----------+-------------+--------+----------------+
| letter_id | description | branch | current_status |
+-----------+-------------+--------+----------------+
| 1 | A | 1 | Pending |
| 2 | B | 4 | Pending |
| 3 | C | 2 | Start |
| 4 | D | 4 | Pending |
| 5 | E | 3 | Start |
| 6 | F | 2 | Finish |
+-----------+-------------+--------+----------------+
letter_action_taken
+------------------------+--------+---------------------+
| letter_action_taken_id | ref_no | action_taken_status |
+------------------------+--------+---------------------+
| 100 | 3 | 1 |
| 101 | 5 | 1 |
| 102 | 6 | 2 |
+------------------------+--------+---------------------+
02）系统正确执行接收到的信件的详细信息以及每个字母的已采取操作。 （letter_action_taken.ref_no = letter_letter.letter_id）
03）我在codeigniter中使用以下方法通过使用“数据表”查看收到的信件与采取的行动
public function getactionTaken($id=null)
{
$this->load->library('datatables');
$this->datatables
->select("letter_letter.letter_id, letter_action.action_name as action, letter_action_taken.forward as forward,
letter_action_taken.a_date as action_date, letter_action_taken.file_no as file_no, letter_action_taken.action_taken_status")
->from('letter_action_taken')
->join('letter_letter','letter_letter.letter_id=letter_action_taken.ref_no')
->join('letter_action','letter_action.action_id=letter_action_taken.action','left')
->where("letter_action_taken.status=1 AND letter_action_taken.ref_no=$id" )
->unset_column("letter_letter.letter_id");
$this->datatables->add_column("Actions", $action, "letter_letter.letter_id");
$branch = $this->session->userdata('branch_id');
if ($branch && $branch !=5)
$this->datatables->where('letter_letter.branch', $branch);
$this->db->order_by('a_date', 'DESC');
echo $this->datatables->generate();
}
并使用了以下HTML / JavaScript / Bootstrap
<style>
.group {
background: #575757 !important;
color: #FFFFFF;
}
.table > tbody > tr > th, .table > tbody > tr > td{
font-size: 13px;
}
</style>
<script type="text/javascript">
$(document).on('change', '#action', function () {
var val = $(this).val();
if(val == 1 || val == 6){
$('#ref-col').hide();
}
else{
$('#ref-col').show();
}
});
$(document).ready(function () {
$('#ref-col').hide();
$(document).ready(function () {
var oTable = $('#ExData').dataTable({
"aaSorting": [[0, "asc"]],
"aLengthMenu": [[10, 25, 50, 100, -1], [10, 25, 50, 100, "ALL"]],

04）通过使用以上代码，系统将显示对混合在一起的所有字母采取的所有操作。出问题了。
但是我需要对字母分别采取措施。 例如：-需要显示letter_action_taken表的第一条记录，该表用于letter_id，3
05）我不明白我要怎么做。任何人都可以参加并帮助我修复此错误吗？
我认为需要在方法中修改以下行。
-> where（“ letter_action_taken.status = 1 AND letter_action_taken.ref_no = $ id”）
