我如何分组表单元素 [英] How can I group form elements

问题描述

 < form method =postaction =accept-charset =utf -8\" > 
< p> 
< label> first_field< / label>< br /> 
< input type =textid =first_fieldname =points []/>< br /> 
< input type =radiovalue =insidename =group_1checked />< br /> 
< input type =radiovalue =outsidename =group_1>< br /> 
< / p> 
< p> 
< label> second_field< / label>< br /> 
< input type =textid =second_fieldname =points []/>< br /> 
< input type =radiovalue =insidename =group_2checked />< br /> 
< input type =radiovalue =outsidename =group_2>< br /> 
< / p> 
< / form> 
  

我想要完成的是检查是否检查了内部或外部，如果外部检查了乘法给定的文字输入点数为1,5。顺便说一句，这需要用PHP来计算。

我该怎么做？

UPDATE

 数组
（
 [bonus] =>数组
（
 [points] = >数组
（
 [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 
（$ b在
 [1] =>以外
 [2] =>以外
 [3] =>以内
 [4] = > insid e 
 [5] =>在
 [6] =>内
 [7] =>在
 [8] =>在
之外[9] =>内
 [10] =>内
 [11] =>内
 [12] =>在
之外[13] =>内
 [14] =>内
）
 
）
 
）
  

以上是print_r（$ _ POST）的结果

现在，我要比较/削减带有组数组的点数组：

points [0]获得连接到组[0]等。

解决方案

事实证明，您可以使用HTML表单对字段进行分组。请在此处查看此代码:(特别注意 name 属性）

  < form method =postaction =accept-charset =utf-8> 
< p> 
< label> first_field< / label>< br /> 
< input type =textid =first_fieldname =field [1] [points]/>< br /> 
< input type =radiovalue =insidename =field [1] [group]checked />< br />> 
< input type =radiovalue =outsidename =field [1] [group]>< br /> 
< / p> 
< p> 
< label> second_field< / label>< br /> 
< input type =textid =second_fieldname =field [2] [points]/>< br /> 
< input type =radiovalue =insidename =field [2] [group]checked />< br />> 
< input type =radiovalue =outsidename =field [2] [group]>< br /> 
< / p> 
< / form> 
  

没有填充任何内容，这会产生一个POST数组，如下所示：

 数组
（
 [field] =>数组
（
 [1] =>数组
（
 [points] => 
 [group] =>里面
）
 
 [2] =>数组
 （
 [points] => 
 [group] =>内部
）
 
）
）
  

我希望这能回答你的问题，这是一个我并没有真正见过许多其他人讨论的巧妙小技巧。有一点需要注意的是，你需要在任何一组括号中手动指定一个ID号码。您只能使用 [] 作为最后一组括号。

I got this form:

<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>

What i want to accomplish is to check if inside or outside is checked, if outside i checked the multiply points for the given text input by 1,5. BTW this needs to be calculated in PHP.

How can I do that?

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
            )

    )

)

Above is the result of print_r($_POST)

Now ho do I compare/pare The points array with the Group array so:

points[0] gets "connected" to group[0] etc.?

解决方案

As it turns out, you can group fields using HTML forms. Check out this code here: (specifically note the name attributes)

<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>

Without filling anything in, this will yield a POST array like this:

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

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

        )
)

I hope this answered your question, it's a neat little trick I haven't really seen many others discuss. One thing to note is that you'll need to manually specify an ID number in that any set of brackets. You can only use [] as the last set of brackets.
