Question

我的模特名称mymodel.php

.....    
function all($table,$order)
        {
            $this->db->select('*');
            $this->db->from($table);
            $this->db->order_by($order);
            $query = $this->db->get();
            if ($query->num_rows() == 0) {
                return FALSE;
            } else {
                return $query->result();
            }
        } .....

我的控制器名称donate.php

.....
    function index()
    {
      $data = array(
                        'rekening' => $this->mymodel->all('rekening', 'id_rekening ASC'),
                        );
                    $this->load->view('client/donate/index', $data);
                } .....

此路径视图中的我的视图/ client / donate / index

<?php foreach ($rekening as $rek): ?>
                <option value="<?php echo $rek->id_rekening; ?>" <?php echo set_select('ke_rekening', $rek->id_rekening); ?>><?php echo $rek->bank .' - '. $rek->atas_nama_rekening; ?></option>
              <?php endforeach ?>

但为什么不能在选择选项中显示？我使用codeigniter 3， Show image

Answer 1

我认为你必须在模态中传递这样的值。

function all($table,$order)
        {
            $this->db->select('*');
            $this->db->from($table);
            $this->db->order_by("id_rekening",$order);
            $query = $this->db->get();
            if ($query->num_rows() == 0) {
                return FALSE;
            } else {
                return $query->result();
            }
        }

如果我弄错了你的问题是获得所有列表，或者你想要选择之前选择的那个选项？

以下是为选择框中的<option>添加值的解决方案。我还添加了如何选择预先选择的值。

  In Model:
    $query = $this->db->select('*')
        ->from($table)
        ->order_by($order)
        ->get();

    $your_result_array = $query->result_array();
    return $your_result_array;


    In Controller:

    $data = $this->mymodel->all($data1,$data2);
    $this->load->view('client/donate/index',['data'=>$data]) ;


    Inside Your View:

    <?php

    if(isset($data) && !empty($data)){
        foreach ($data as $single_data){

        ?> <option value="<?= $data['id_rekening] ?>" <?= $your_selected_value_array['your_selected_value'] === $data['id_rekening] ? 'selected':''  ?> > <?= $data['your_other_data_column_name_here] ?> </option> <?php

        }
    }else {

          ?><option> data not found </optiop> <?php
    }
    ?>

Answer 3

controller donate.php

function index()
{
  $data = array('rekening' => $this->mymodel->all('rekening', 'id_rekening'));
  $this->load->view('client/donate/index', $data);
}

模型donate.php

function all($table,$order)
{
   $this->db->select('*');
   $this->db->from($table);
   $this->db->order_by($order, 'asc');
   $query = $this->db->get();
   if ($query->num_rows() == 0) {
      return FALSE;
   } else {
      return $query->result();
   }
}

无法将结果显示为选择选项Codeigniter 3
