Question

我有这样的表格：

<form method="post" action="mypage.php" orderform="" name="" id="orderform">
<a id="add">+</a>
 <table width="533" cellspacing="0" cellpadding="2" border="0" id="ordertable">
  <tbody>
    <tr>
      <td width="33%">Product Code (e.g 66203)</td>
      <td width="33%">mtrs sq Required (e.g 10)</td>
      <td width="33%">Preview Image</td>
    </tr>
    <tr class="item">
      <td class="prodcode "><input type="text" id="prodcode[]" name="prodcode[]" class=" "></td>
      <td class="meterage"><input type="text" id="meterage[]" name="meterage[]"></td>
      <td class="imgsample"></td>
    </tr>
    <tr class="item">
      <td class="prodcode "><input type="text" id="prodcode[]" name="prodcode[]" class=" "></td>
      <td class="meterage"><input type="text" id="meterage[]" name="meterage[]"></td>
      <td class="imgsample"></td>
    </tr>
    </tbody>
  </table>
  <button>Submit</button>
</form>

我正在尝试接收帖子并用其计量打印副产品价值......如下所示（这似乎只返回最后的结果）任何想法？

    $number_of_products=count($_POST['prodcode']);
   for ( $i=0; $i<$number_of_products; $i++){
       $orderdetails = $_POST['prodcode'][$i]." has the meterage: ".$_POST['meterage'][$i]."<br/>";
   }

Answer 1

每次运行for循环时，你都会覆盖$ orderdetails的内容。

尝试这样的事情：

$number_of_products=count($_POST['prodcode']);
$orderdetails = "<h1>Order Details</h1>";
for ( $i=0; $i<$number_of_products; $i++){
       $orderdetails .= $_POST['prodcode'][$i]." has the meterage: ".$_POST['meterage'][$i]."<br/>";
}

Answer 2

尝试为输入字段上的prodcode[]和meterage[]名称编制索引，即：

<form method="post" action="mypage.php" orderform="" name="" id="orderform">
<a id="add">+</a>
 <table width="533" cellspacing="0" cellpadding="2" border="0" id="ordertable">
  <tbody>
    <tr>
      <td width="33%">Product Code (e.g 66203)</td>
      <td width="33%">mtrs sq Required (e.g 10)</td>
      <td width="33%">Preview Image</td>
    </tr>
    <tr class="item">
      <td class="prodcode "><input type="text" id="prodcode_0" name="prodcode[0]" class=" "></td>
      <td class="meterage"><input type="text" id="meterage_0" name="meterage[0]"></td>
      <td class="imgsample"></td>
    </tr>
    <tr class="item">
      <td class="prodcode "><input type="text" id="prodcode_1" name="prodcode[1]" class=" "></td>
      <td class="meterage"><input type="text" id="meterage_1" name="meterage[1]"></td>
      <td class="imgsample"></td>
    </tr>
    </tbody>
  </table>
  <button>Submit</button>
</form>

Answer 3

因为你每次都会覆盖它更改 $ orderdetails = 至 $ orderdetails。=

从已发布的数组中提取所有表单值
