Question

我正在尝试学习CI这个方面的项目，但目前有一些我没有找到答案的错误。我已经尝试了一些建议/答案，例如die($this->db->last_query());和var_dump 但它仍然显示错误。我使用<?php echo print($list_rawmat) ?>在我的视图中显示了数据但它不会出现在表格中（同一页面）这是视图

<?php echo print($list_rawmat) ?>
<div id="list_data_rawmat">
  <table class="table table-hover text-centered">
    <tr>
      <td><b>No.</td>
            <td><b>Jenis Barang</td>
            <td><b>Nama Barang</td>
            <td><b>Harga Satuan</td>
            <td><b>Jumlah</td>
            <td><b>Satuan</td>
            <td><b>Berat</td>
            <td><b>Edit/Delete</td>
        </tr>
        <?php

        $i = 1;
             foreach($list_rawmat as $row)
            {
                $type = "Raw Material";
                echo "<tr> 
                <td>".$i++."</td>
                <td>".$type."</td>
                <td>".$row->rawmat_name."</td>
                <td>".$row->rawmat_price."</td>
                <td>".$row->qty."</td>
                <td>".$row->qty_nama."</td>
                <td>".$row->weight."</td>
    </tr>"; 
            }
            ?>
    </table>
</div>

这是模型

    *$proyek = AM1 (it was sent by previous page)
function list_rawmat($proyek){
        $sql = "SELECT * FROM order_table g, order_detail b 
            WHERE g.project_id = '".$proyek."' AND g.order_detail_id = b.order_detail_id";
    $item_id = $this->db->query($sql)->result();
    $i = 0;
    $result = array();
    foreach($item_id as $row){
        if ($row->rawmat_id != null) {
            $sql2 = "SELECT g.order_id, g.order_date, g.total, b.qty, i.rawmat_id, i.rawmat_name, i.rawmat_price, b.weight, h.qty_nama
        FROM order_table g, order_detail b, raw_material i, quantity_type h
        WHERE g.project_id = '".$proyek."' AND b.rawmat_id = i.rawmat_id 
        AND h.qty_type_id = b.qty_type_id AND g.order_detail_id = b.order_detail_id ";
            $query = $this->db->query($sql2);
            $result[$i++] = $query->result();
        }
    }
    return $result;
}

最后这里是控制器

*$this->session->project_id = AM1 (sent from view before the view in question)
function view_data_rawmat(){
    $config['base_url'] = base_url().'index.php/c_data/index';
    $config['total_rows'] = $this->m_data->count();
    $config['per_page'] = 10;
    $config['next_link'] = 'Selanjutnya';
    $config['prev_link'] = 'Sebelumnya';
    $config['uri_segment'] = 3;
    $this->pagination->initialize($config); 
    $offset=$this->uri->segment(3);     
    $data['list_rawmat'] = $this->m_data->list_rawmat($this->session->project_id);
    $str_links = $this->pagination->create_links();
    $data["links"] = explode('&nbsp;',$str_links );
    $this->load->view ('view_header');
    $this->load->view ('view_data_rawmat',$data);
    $this->load->view ('view_footer');
    //die($this->db->last_query());
}

这是echo print_r ($list_rawmat);

的结果

Array ( [0] => Array ( 
[0] => stdClass Object ( [order_id] => 5 [order_date] => 2016-04-05 [total] => 876348553 [qty] => 313 [rawmat_id] => 1 [rawmat_name] => WF - 346x174x6x9 L.9000mm [rawmat_price] => 7514 [weight] => 116624 [qty_nama] => Bh )

[1] => Array (

我不知道为什么阵列是这样的，请也赐教我。
