单选按钮发布多个输入字段的数据 [英] Radio button post data of multiple input fields

问题描述

我的 PHP 页面中有一个表单，它是通过数组循环创建的.

I have a form in my PHP page which is created by a loop through an array.

echo '<form method="POST" name="add_to_cart_form">
        <div id="Product_add_sizes">
           <table border="0" cellpadding="2" class="product_txt_font" align="center">
              <input type="hidden" name="product_id" value="'.$arr_get_products[$c]['id'].'">';

                   for ($d = 0; $d < count($arr_get_product_details); $d++)
                   {
                      echo '<tr>
                              <td>
                                 <input type="radio" name="size[]" value="'.$arr_get_product_details[$d]['size'].'">
                              </td>
                              <td>
                                 <input class="qty" type="text" size="3" name="amount" value="1">
                              </td>
                            </tr>';
                   }

     echo '</table>
          <input type="submit" name="add_to_chart" value="Add Product" />
        </div>
      </form>';

现在，当我发布此表单时，我正在寻找一种方法来获取属于所选单选按钮的数量的输入.我只需要所选单选按钮行中的数据.不需要其他数据，因为我想将此产品添加到购物车数组中.

Now when I post this form, I'm searching for a way to get the input of qty which belongs to the selected radio button. I only need the data from the selected radio button row. The other data is not needed as I want to add this product to a shopping cart array.

if (isset($_POST['add_to_chart']))
{
    $product_id = $_POST['product_id'];
    $size = $_POST['size'][0];
    $qty = $_POST['amount'];
}

发布页面时，我知道 size[] 需要什么尺寸数组，但我无法获得与所选单选按钮匹配的相关数量值.

When posting the page, I know what size is wanted cause of the size[] array but I can't get the related qty value that matches the selected radio button.

我试图通过将 qty 设为数组 qty[] 来以与单选按钮相同的方式处理 qty，但这将返回所有值.

I've tried to treat the qty the same way as the radio button by making it an array qty[] but that will return me all values.

我搜索了 SO 并用谷歌搜索了一堆，但没有找到一个像样的答案，但在我看来，这已经被大量使用了.请让我知道我在这里缺少什么.

I've search SO and googled a bunch but haven't found a decent answer, but It looks to me that this is used a lot. Please let me know what i'm missing here.

非常感谢任何帮助！

The guys above here all got me on the right track and couldn't have done it without them!

改变了

<input type="radio" name="size[]" value="'.$arr_get_product_details[$d]['size'].'">
<input class="qty" type="text" size="3" name="amount" value="1">

到

<input type="radio" name="size['.$d.']" value="'.$arr_get_product_details[$d]['size'].'">
<input class="qty" type="text" size="3" name="amount['.$d.']" value="1">

也改了

if (isset($_POST['add_to_chart']))
{
    $product_id = $_POST['product_id'];
    $size = $_POST['size'][0];
    $qty = $_POST['amount'];
}

到这里

if (isset($_POST['add_to_chart']))
{
    // Array ID key
    $key = key($_POST['size']);

    $product_id = $_POST['product_id'];
    $size = $_POST['size'][$key];
    $qty = $_POST['amount'][$key];
}
