如何从表中删除表过滤器搜索 - ajax with codeigniter 3

问题描述

所以我尝试了本教程：https://mbahcoding.com/tutorial/php/codeigniter/codeigniter-ajax-crud-modal-server-side-validation.html

我的数据显示如下：image of how the data & the features looks

我只想显示表格并使用图片中绿色标志上的搜索功能。但是，当我按照教程进行操作时，会显示一些功能（例如：图片中的红色和蓝色符号）。

哪里可以更改去除图片中的红色特征，将图片中的蓝色标志特征移到绿色标志上？

我仍在学习 ajax 的工作原理。对不起，如果我的解释太复杂了。但是，我希望你能理解...希望你能帮助我...

这是我在模型中使用的函数 - detkelModel.PHP：

var $table = 'detail_keluarga';
    var $column_order = array('nama','hubungan','personilid','lahir',null); //set column field database for datatable orderable
    var $column_search = array('nama','lahir'); //set column field database for datatable searchable just nama,hubungan,personilid,lahir are searchable
    var $order = array('id' => 'desc'); // default order

    private function _get_datatables_query()
    {

        $this->db->from($this->table);

        $i = 0;

        foreach ($this->column_search as $item) // loop column 
        {
            if ($_POST['search']['value']) // if datatable send POST for search
            {

                if ($i === 0) // first loop
                {
                    $this->db->group_start(); // open bracket. query Where with OR clause better with bracket. because maybe can combine with other WHERE with AND.
                    $this->db->like($item,$_POST['search']['value']);
                } else {
                    $this->db->or_like($item,$_POST['search']['value']);
                }

                if (count($this->column_search) - 1 == $i) //last loop
                    $this->db->group_end(); //close bracket
            }
            $i++;
        }

        if (isset($_POST['order'])) // here order processing
        {
            $this->db->order_by($this->column_order[$_POST['order']['0']['column']],$_POST['order']['0']['dir']);
        } else if (isset($this->order)) {
            $order = $this->order;
            $this->db->order_by(key($order),$order[key($order)]);
        }
    }

    function get_datatables()
    {
        $this->_get_datatables_query();
        if ($_POST['length'] != -1)
            $this->db->limit($_POST['length'],$_POST['start']);
        $query = $this->db->get();
        return $query->result();
    }

    function count_filtered()
    {
        $this->_get_datatables_query();
        $query = $this->db->get();
        return $query->num_rows();
    }

    public function count_all()
    {
        $this->db->from($this->table);
        return $this->db->count_all_results();
    }

这是我对表格和搜索栏的看法 - detkel.PHP：

<div class="navbar navbar-expand navbar-white navbar-light">
    <!--left navbar / Data Keluarga label-->
    <div class="col-sm-6 float-left">
        <h5>Data Keluarga Personil</h5>
    </div>
    <!-- Right navbar links -->
    <ul class="navbar-nav ml-auto">
        <!-- Navbar Search,filter,plus data -->
        <li class="nav-item">
            <div class="form-inline">
                <div class="input-group" data-widget="search-bar">
                </div>
            </div>
        </li>
        <!-- Filter Dropdown Menu -->
        <li>
        </li>
        <!-- Plus data dropdown menu -->
        <li>
            <a class="btn btn-default" data-toggle="dropdown" href="#">
            </a>
            <div class="dropdown-menu dropdown-menu-lg dropdown-menu-right">
            </div>
        </li>
    </ul>
</div>
<div class="card">
    <div class="table-responsive p-0">
        <table id="table" class="table table-hover text-Nowraps">
            <thead>
                <tr>
                    <th>Nama</th>
                    <th>id personil</th>
                    <th>Hubungan</th>
                    <th>Tanggal Lahir</th>
                    <th>Aksi</th>
                </tr>
            </thead>
            <tbody>
            </tbody>
        </table>
    </div>
</div>

这是我认为的脚本

<script type="text/javascript">
    var save_method; //for save method string
    var table;
    $(document).ready(function() {
        //datatables
        table = $('#table').DataTable({
            "processing": true,//Feature control the processing indicator.
            "serverSide": true,//Feature control DataTables' server-side processing mode.
            "order": [],//Initial no order.
            // Load data for the table's content from an Ajax source
            "ajax": {
                "url": "<?PHP echo site_url('DetkelController/ajax_list') ?>","type": "POST"
            },//Set column deFinition initialisation properties.
            "columnDefs": [{
                "targets": [-1],//last column
                "orderable": false,//set not orderable
            },],});
    });
</script>

这是我的控制器中的 ajax_list() DetkelController.PHP：

public function ajax_list()
{
    $list = $this->dk->get_datatables();
    $data = array();
    //$no = $_POST['start'];
    foreach ($list as $dk) {
        //$no++;
        $row = array();
        $row[] = $dk->nama;
        $row[] = $dk->hubungan;
        $row[] = $dk->personilid;
        $row[] = $dk->lahir;

        //add html for action
        $row[] = '<a class="btn btn-sm btn-primary" href="javascript:void(0)" title="Edit" onclick="edit_person(' . "'" . $dk->id . "'" . ')"><i class="glyphicon glyphicon-pencil"></i> Edit</a>
                <a class="btn btn-sm btn-danger" href="javascript:void(0)" title="Hapus" onclick="delete_person(' . "'" . $dk->id . "'" . ')"><i class="glyphicon glyphicon-trash"></i> Delete</a>';

        $data[] = $row;
    }

    $output = array(
        "draw" => $_POST['draw'],"recordsTotal" => $this->dk->count_all(),"recordsFiltered" => $this->dk->count_filtered(),"data" => $data,);
    //output to json format
    echo json_encode($output);
}
