mysql - 打印 PHP 数组 HTML View 中的所有元素

Question

我有一个 codeigniter 项目，它以最简单的形式描述如下表

tbl_direct_fuel 表

+----------------+------------+------------+
| direct_fuel_id | vehicle_id | issue_date |
+----------------+------------+------------+
|              1 |       1000 | 2019-10-01 |
|              2 |       1001 | 2019-10-02 |
+----------------+------------+------------+

tbl_direct_fuel_details 表

+-----------------------+----------------+---------+----------+
| direct_fuel_detail_id | direct_fuel_id | item_id | fuel_qty |
+-----------------------+----------------+---------+----------+
|                   100 |              1 |      50 |     1.00 |
|                   101 |              2 |      60 |     2.00 |
+-----------------------+----------------+---------+----------+

store_item 表

+---------+-----------+
| item_id | item_name |
+---------+-----------+
|      50 | DOT 3     |
|      60 | DOT 4     |
|      70 | DOT 5     |
+---------+-----------+

我尝试使用我的 View 以数字和文字打印 fuel_qty，如下所示

1.00    One and Cents Zero Only
2.00    Two and Cents Zero Only

型号

public function directFuelQtyById($id) {

        $this->db->select('tbl_direct_fuel_details.fuel_qty');
        $this->db->from('tbl_direct_fuel_details');
        $this->db->join('tbl_direct_fuel', 'tbl_direct_fuel_details.direct_fuel_id=tbl_direct_fuel.direct_fuel_id', 'inner');

        $this->db->where('tbl_direct_fuel.status=1 and tbl_direct_fuel.direct_fuel_id="'.$id.'"');
        $this->db->order_by('tbl_direct_fuel.direct_fuel_id','DESC');
        $q = $this->db->get();

        if ($q->num_rows() > 0) {
            return $q->result();
        }
        return false;
    }

    {

        $hyphen = ' ';
        $conjunction = ' and ';
        $separator = ' ';

                    $string .= $hyphen . $dictionary[$units];

        $fuel = $this->Fuel_model->directFuelQtyById($id);      
        foreach($fuel as $obj)

    }

查看(打印燃料)

<html>
<head>
    <title>Fuel Order</title>
</head>
<body onload="window.print()">
<body>

<div class="col-xs-12 table-responsive">
<table class="table table-bordered"  style="font-size: 13px; ">
<tbody>
<?php
if (!empty($printData)) {
  $offset=1; // cm
  $cnt=0;
  foreach ($printData as $item) {
?>
<tr>        

  <td><p style="position: absolute;top: <?= ($cnt*$offset)+20 ?>cm;right: 12cm"><?=$item->fuel_qty?> Litres</p></td>
  <td><p style="position: absolute;top: <?= ($cnt*$offset)+20 ?>cm;right: 8cm"><?=$this->amount_word?></p></td>                           
</tr> 
<?php $cnt++; 
  } // close your foreach HERE
  ?>         
</tbody>
</table>
</div>

<?php   
}    
?>
</body>
</html>

但是当转换为单词时，该函数只打印 <?=$this->amount_word?> 的最后一个元素。 ，如下所示:

1.00    Two and Cents Zero Only
2.00    Two and Cents Zero Only

如何得到想要的输出？

1.00    One and Cents Zero Only
2.00    Two and Cents Zero Only

Answer 1

在您的函数 printFuel($id) 中，您将用每个新数组值覆盖 $this->amount_word。因此，您只能获得最后一个值。

因此，只需使用函数 convert_number_to_words() 在你的 Controller 中:

public function printFuel($id){
    $arr=$this->Fuel_model->directFuelById($id);               
    foreach($arr as $key=>$obj)
    { 
       $str=$this->convert_number_to_words($obj->fuel_qty) . '<br>'." Only";
       $arr[$key]->fuel_qty_str=$str;    
    }
    $data['printData']=$arr;
    $this->load->view('/template/directFuel/printFuel',  $data);

}

然后在你的 View 中输出数组:

foreach ($printData as $item) {
  ?>
  <tr>          
    <td>
      <p style="position: absolute;top: <?= ($cnt*$offset)+20 ?>cm;right: 12cm">
        <?=$item->fuel_qty?> Litres
      </p>
    </td>
    <td>
      <p style="position: absolute;top: <?= ($cnt*$offset)+20 ?>cm;right: 8cm">
        <?=$item->fuel_qty_str?>
      </p>
    </td>                           
  </tr> 
  <?php $cnt++; 
}
