Html / PHP - 表单 - 输入为数组 [英] Html/PHP - Form - Input as array

问题描述

我有这样的表格

 < form> 
< input type =textclass =form-controlplaceholder =Titelname =levels [level]> 
< input type =textclass =form-controlplaceholder =Titelname =levels [build_time]> 
 
< input type =textclass =form-controlplaceholder =Titelname =levels [level]> 
< input type =textclass =form-controlplaceholder =Titelname =levels [build_time]> 
 
< / form> 
  

我想要的$ _POST输出是一个像

$ b这样的数组数组（
[1] =>数组（[level] => 1 [build_time] => 123）$ b $（
$ b pre $ b [2] => Array（[level] => 2 [build_time] => 456）
）


我知道我可以做类似name =levels [1] [build_time]等等，但是因为这些元素是动态添加的，所以很难添加索引。有没有其他的办法？

编辑：

我的形式。我现在也包括了我的整个HTML，因为我觉得我在这里错过了一些东西。我的HTML现在：

 < div class =form-group> 
< label class =col-md-2>名称（z.B。1）< / label> 
< div class =col-md-10> 
< input type =textclass =form-controlplaceholder =Titelname =levels [] [level]> 
< / div> 
 
< label class =col-md-2> Bauzeit（In Sekunden）< / label> 
< div class =col-md-10> 
< input type =textclass =form-controlplaceholder =Titelname =levels [] [build_time]> 
< / div> 
< / div> 
 
< div class =form-group> 
< label class =col-md-2>名称（z.B。1）< / label> 
< div class =col-md-10> 
< input type =textclass =form-controlplaceholder =Titelname =levels [] [level]> 
< / div> 
 
< label class =col-md-2> Bauzeit（In Sekunden）< / label> 
< div class =col-md-10> 
< input type =textclass =form-controlplaceholder =Titelname =levels [] [build_time]> 
< / div> 
< / div> 
  

我现在得到的输出是：

  [levels] =>数组（
 [0] =>数组（[level] => 1）
 [1] =>数组（[build_time] => 234） > Array（[level] => 2）
 [3] => Array（[build_time] => 456）
）
  pre>

形成并将方括号移到名称的末尾。我现在得到的输出是：
 
 
  [levels] => Array（
 [level] => Array（
 [0] => 1 
 [1] => 2 
）
 [build_time] => ;数组（
 [0] => 234 
 [1] => 456 
）
）
  
我猜这样做可能会有用，但它看起来很复杂。没有更好的办法吗？
          
 < input type =textclass =form-controlplaceholder =Titelname =levels [level ] []> 
< input type =textclass =form-controlplaceholder =Titelname =levels [build_time] []> 
  
获取该模板，然后您可以使用循环添加这些模板。
 
 
 
然后，您可以根据需要动态添加这些内容，而不必提供索引。 PHP将会像你期望的场景例子一样提取它们。

对不起，我在错误的地方有大括号，这会使每个新值都成为一个新的数组元素。现在使用更新后的代码，这会给你以下数组结构： 
 
 
  levels> level（Array）
 levels> build_time（Array）
  
两个子阵列上的相同索引会为您提供配对。例如
  echo $ levels [level] [5]; 
 echo $ levels [build_time] [5]; 
  
 
I got a form like this
<form>
<input type="text" class="form-control" placeholder="Titel" name="levels[level]">
<input type="text" class="form-control" placeholder="Titel" name="levels[build_time]">

<input type="text" class="form-control" placeholder="Titel" name="levels[level]">
<input type="text" class="form-control" placeholder="Titel" name="levels[build_time]">

</form>
What I'd like to have as $_POST output is an array like
Array ( 
  [1] => Array ( [level] => 1 [build_time] => 123 ) 
  [2] => Array ( [level] => 2 [build_time] => 456 )
)
I know I could do something like name="levels[1][build_time]" and so on but since these elements get added dynamically, it would be hard to add an index. Is there any other way?


EDIT:

As suggested, I changed my form. I also included my whole HTML now, because I think I'm missing something here. My HTML now:
<div class="form-group">
  <label class="col-md-2">Name(z.B. 1)</label>
  <div class="col-md-10">
    <input type="text" class="form-control" placeholder="Titel" name="levels[][level]">
  </div>

  <label class="col-md-2">Bauzeit(In Sekunden)</label>
  <div class="col-md-10">
    <input type="text" class="form-control" placeholder="Titel" name="levels[][build_time]">
  </div>
</div>

<div class="form-group">
  <label class="col-md-2">Name(z.B. 1)</label>
  <div class="col-md-10">
    <input type="text" class="form-control" placeholder="Titel" name="levels[][level]">
  </div>

  <label class="col-md-2">Bauzeit(In Sekunden)</label>
  <div class="col-md-10">
    <input type="text" class="form-control" placeholder="Titel" name="levels[][build_time]">
  </div>
</div>
The output I get now is:
[levels] => Array ( 
  [0] => Array ( [level] => 1 ) 
  [1] => Array ( [build_time] => 234 ) 
  [2] => Array ( [level] => 2 ) 
  [3] => Array ( [build_time] => 456 ) 
)
Edit 2:

As suggested in your edit, I edited my form and moved the square brackets to the end of the name. The output I get now is:
[levels] => Array ( 
  [level] => Array ( 
    [0] => 1 
    [1] => 2 
  ) 
  [build_time] => Array ( 
    [0] => 234 
    [1] => 456 
  )
) 
I guess that would kinda work but it still looks complicated. No better way?
解决方案
Simply add [] to those names like
 <input type="text" class="form-control" placeholder="Titel" name="levels[level][]">
 <input type="text" class="form-control" placeholder="Titel" name="levels[build_time][]">
Take that template and then you can add those even using a loop.

Then you can add those dynamically as much as you want, without having to provide an index. PHP will pick them up just like your expected scenario example.

Edit

Sorry I had braces in the wrong place, which would make every new value as a new array element. Use the updated code now and this will give you the following array structure
levels > level (Array)
levels > build_time (Array)
Same index on both sub arrays will give you your pair. For example
echo $levels["level"][5];
echo $levels["build_time"][5];
