如何对表单元素进行分组

Question

我得到了这个表格:

<form method="post" action="" accept-charset="utf-8"> 
<p>
  <label>first_field</label><br />
  <input type="text" id="first_field" name="points[]" /><br />
  <input type="radio" value="inside" name="group_1" checked /><br />
  <input type="radio" value="outside" name="group_1"><br />
</p>
<p>
  <label>second_field</label><br />
  <input type="text" id="second_field" name="points[]" /><br />
  <input type="radio" value="inside" name="group_2" checked /><br />
  <input type="radio" value="outside" name="group_2"><br />
</p>
</form>

我想要完成的是检查内部或外部是否被检查,如果在外面我检查给定文本输入的乘法点为1.5.BTW需要用PHP计算.

我怎样才能做到这一点？

UPDATE

Array
(
[bonus] => Array
    (
        [points] => Array
            (
                [0] => 0
                [1] => 0
                [2] => 0
                [3] => 0
                [4] => 0
                [5] => 0
                [6] => 0
                [7] => 0
                [8] => 0
                [9] => 0
                [10] => 0
                [11] => 0
                [12] => 0
                [13] => 0
                [14] => 0
            )

        [group] => Array
            (
                [0] => inside
                [1] => outside
                [2] => outside
                [3] => inside
                [4] => inside
                [5] => inside
                [6] => inside
                [7] => inside
                [8] => outside
                [9] => inside
                [10] => inside
                [11] => inside
                [12] => outside
                [13] => inside
                [14] => inside
            )

    )

)

以上是print_r($ _ POST)的结果

现在我要将点数组与Group数组进行比较/删除,这样:

points [0]与组[0]等"连接"？

事实证明,您可以使用HTML表单对字段进行分组.在这里查看此代码:(特别注意name属性)

<form method="post" action="" accept-charset="utf-8">
<p>
  <label>first_field</label><br />
  <input type="text" id="first_field" name="field[1][points]" /><br />
  <input type="radio" value="inside" name="field[1][group]" checked /><br />
  <input type="radio" value="outside" name="field[1][group]"><br />
</p>
<p>
  <label>second_field</label><br />
  <input type="text" id="second_field" name="field[2][points]" /><br />
  <input type="radio" value="inside" name="field[2][group]" checked /><br />
  <input type="radio" value="outside" name="field[2][group]"><br />
</p>
</form>

如果没有填充任何内容,这将产生一个这样的POST数组:

Array
(
    [field] => Array
        (
            [1] => Array
                (
                    [points] => 
                    [group] => inside
                )

            [2] => Array
                (
                    [points] => 
                    [group] => inside
                )

        )
)

我希望这能回答你的问题,这是一个很好的小技巧,我没有看到很多人讨论过.需要注意的一点是,您需要在任何一组括号中手动指定ID号.您只能[]用作最后一组括号.
