对PHP表单数组使用HTML字段集 [英] Using HTML Fieldsets for PHP form arrays

问题描述

我知道您可以将名称数组用于多个表单输入(例如<input type="text" name="username[]">，但是也可以将其用于整个字段集吗?如何使用PHP $ _POST global来操纵它?

I know you can use name arrays for multiple form inputs (e.g. <input type="text" name="username[]">, but can this also be used for entire fieldsets? How would this be manipulated with the PHP $_POST global?

这就是我想要做的:

<fieldset name="player[]">
  <input type="text" name="username">
  <input type="number" name="points">
</fieldset>

<fieldset name="player[]">
  <input type="text" name="username">
  <input type="number" name="points">
</fieldset>

之所以尝试这样做，是因为我正在构建一个允许用户动态添加/减去玩家"字段集的表单.如果您有比我要求的解决方案更好的解决方案，请随时提供替代方案.

The reason why I am trying to do this is because I am building a form that allows the user to dynamically add/subtract "player" fieldsets. If you have a better solution than what I was asking for, please feel free to provide an alternative.

推荐答案

或者，如果您希望进行这种分组，则可以按照以下形式创建分组:考虑以下示例:

Alternatively, if you want such grouping you could create a grouping in your form such as this: consider this example:

<form method="POST" action="">
    <fieldset>
        Username: <input type="text" name="player[0][username]" />
        Points: <input type="number" name="player[0][points]" />
    </fieldset>

    <fieldset>
        Username: <input type="text" name="player[1][username]" />
        Points: <input type="number" name="player[1][points]" />
    </fieldset>


    <br/>
    <input type="submit" name="submit" />
</form>

处理时:

if(isset($_POST['submit'])){
    $all_players = $_POST['player'];
    echo '<pre>';
    print_r($all_players);
    echo '</pre>';
}

它应该产生如下内容:

Array
(
    [0] => Array
        (
            [username] => Test1
            [points] => 1
        )

    [1] => Array
        (
            [username] => Test2
            [points] => 2
        )

)
