Question

如何在数据表中创建自定义数据过滤器？，

如果我选择选项框中的一行：

然后datatables将在datatables中显示选项框的值：

这是我在自定义搜索中想要的示例：

最后我的自定义搜索成功了

我从数据库

中的表dept显示连接中的数据（Department）

在我的数据表中我在数据库中使用了表emp

这是我的代码选项框

<div class="row">
    <div class="col-md-6">
      <form action="<?=site_url('proses/pindah_departemen');?>" method="get">
        <div class="panel panel-primary">
            <div class="panel-heading">Filter Data</div>
            <div class="panel-body">
                <table class="table table-bordered">
                    <tr>
                        <td width="20%">Pilih Departemen</td>
                        <td width="30%">
                            <select class="form-control" name="filter_departemen">
                                <option value="" <?php if(empty($this->input->get('filter_departemen'))) echo 'selected';?>>Show All data</option>
                                <?php
                                foreach($groups as $city)
                                {
                                    $selected = $this->input->get('filter_departemen')==$city['dept_id_auto'] ? 'selected':'';
                                    echo '<option value="'.$city['dept_id_auto'].'" '.$selected.'>'.$city['dept_name'].'</option>';
                                }
                                ?> 
                            </select>
                        </td>
                    </tr>
                </table>
            </div>
            <div class="panel-footer text-right">
                <button type="submit" class="btn btn-primary">Tampilkan Data</button>
            </div>
        </div>
      </form>
    </div>
  </div>

这是我的控制器命名（Proses）：

public function pindah_departemen()
{
    $data = array(
        'title'     => 'Pindah Departemen',
        'data' => $this->Pindah_dept_model->GetSiswa($this->input->get('filter_departemen'))
    );

    $data['groups'] = $this->Pindah_dept_model->getAllGroups();

    $this->template->load('template','proses/pindah_departemen', $data);
}

这个我的模型命名（Pindah_dept_model）：

var $table = 'emp';

public function GetSiswa()
{
    /*i dont know exactly  your query. please fix this is this wrong*/
    $this->db->select(array('emp_id', 'first_name', 'nik', 'gender', 'pin', 'dept_name'))
        ->from('emp AS e')
        ->join('dept AS d','d.dept_id_auto = e.dept_id_auto', 'left');
    if(!empty($dep)) $this->db->where('d.dept_id_auto', $dep); 
    $data = $this->db->order_by('emp_id','ASC')->get();
    return $data->result_array();
}

public function getAllGroups()
{
    $query = $this->db->query('SELECT dept_id_auto,dept_name FROM dept');
    return $query->result_array();
}

如果我已正确理解该问题，您需要在selectbox的“getAllGroup”函数中添加一个过滤器。如果我错了，请纠正我。

您应该为select添加一个名称，我将其命名为“dept_filter”。

<div class="row">
  <div class="col-md-6">
    <div class="panel panel-primary">
        <div class="panel-heading">Filter Data</div>
        <form action="" method="post">
        <div class="panel-body">
                  <table class="table table-bordered">
            <tr>
              <td width="20%">Pilih Departemen</td>
              <td width="30%">
                <select class="form-control" name="dept_filter">
                  <?php
                    foreach($groups as $city)
                    {
                        echo '<option value="'.$city['dept_id_auto'].'">'.$city['dept_name'].'</option>';
                    }
                  ?> 
                </select>
              </td>
            </tr>
          </table>          
        </div>
        <div class="panel-footer text-right">
          <input type="submit" class="btn btn-primary" value="Tampilkan Data">
        </div>
        </form>
      </div>
    </div>
  </div>

在你的Proses控制器中：

public function pindah_departemen()
{

    //we take the current selected option (return false when none)
    $filter_dept = $this->input->post('dept_filter');

    //and we pass it to the model
    $data = array(
        'title'     => 'Pindah Departemen',
        'data' => $this->Pindah_dept_model->GetSiswa($filter_dept)
    );
    $data['groups'] = $this->Pindah_dept_model->getAllGroups();

    $this->template->load('template','proses/pindah_departemen', $data);
}

在您的模型中：我已在codeigniter查询生成器语法中转换您的SQL查询。

    /*to avoid any conflict if this function is used anywhere else, 
    I made the param optionnal, so if there is none, 
    the filter is set to "false"*/
    public function GetSiswa($filter = FALSE)
    {

        $this->db->select();
        $this->db->from($this->table); //here "emp"
        //do the same join as your query
        $this->db->join('dept', 'debt.dept_id_auto = emp.dept_id_auto'); 

        //when the filter isn't false, we add a "where" condition
        if($filter){
            $this->db->where("dept_id_auto", $filter);
        }

        $this->db->order_by("emp_id", "DESC");

        $query = $this->db->get();

        return $data->result_array();
    }

Udpate：代码更新为当前问题。

Udpate2：在条件

更新3：通过添加表单标记

如果你没有取得好成绩：

您在<select>...</select>？

<form>

您在method="post"使用<form>吗？
您是否可以检查控制器中是否收到了发布数据 var_dump($this->input->post());
您可以通过添加行检查GetSiswa（）函数中的当前查询运行吗？ echo $this->db->last_query(); 在回归之前？

你的过滤器html

<div class="row">
    <div class="col-md-6">
        <form action="<?=site_url('proses/pindah_departemen');?>" method="get">
            <div class="panel panel-primary">

                                    {
                                        $selected = $this->input->get('filter_departemen')==$city['dept_id_auto'] ? 'selected':'';
                                        echo '<option value="'.$city['dept_id_auto'].'" '.$selected.'>'.$city['dept_name'].'</option>';
                                    }
                                    ?> 
                                </select>
                            </td>

                </div>
            </div>
        </form>
    </div>
</div>

你的控制器

public function pindah_departemen()
{
    // MASUKKAN PARAMETER DATA DISINI, BIASANYA HASIL DARI QUERY
    $data = array(
            'title'     => 'Pindah Departemen',
            'data' => $this->Pindah_dept_model->GetSiswa($this->input->get('filter_departemen'))
        );
    $data['groups'] = $this->Pindah_dept_model->getAllGroups();
    $this->template->load('template','proses/pindah_departemen', $data);
}

你的模特

var $table = 'emp';

public function GetSiswa($dep=NULL)
{
    $this->db->select(array('emp_id', 'first_name', 'nik', 'gender', 'pin', 'dept_name')) //or select(array('emp_id, first_name, nik, gender, pin, dept_name')
        ->from('emp AS e')
        ->join('dept AS d','d.dept_id_auto = e.dept_id_auto', 'left');
    if(!empty($dep)) $this->db->where('dept_id_auto', $dep);
    $data = $this->db->order_by('emp_id','ASC')->get();
    return $data->result_array();
}

public function getAllGroups()
{
    $query = $this->db->query('SELECT dept_id_auto,dept_name FROM dept');
    return $query->result_array();
}

public function get_by_id_siswa($id)
{
    $this->db->from($this->table);
    $this->db->where('emp_id',$id);
    $query = $this->db->get();

    return $query->row();
}
