如何用这样的HTML数组输入？

Question

我有一个循环的laravel代码，这是示例输入

<input type="hidden" value="{{ $question['question'] }}" name="custom_form[question][{{ $question['name'] }}]" />
<input type="text" name="custom_form[answer][{{ $question['name'] }}]" />

，结果就像这样

任何想法如何做到这样的结果？

Array
(
    (
        [immigration_status] => Array
                    (
                        [question]  => What is your current Immigration status?
                        [answer]    => Naturalized Citizen
                    )
        [green_card] => Array
                    (
                        [question]  => Do you have a Green Card?
                        [answer]    => Yes
                    )
        ....
    )

)

如果在<input>上没有这样的话，那么如何在foreach循环上执行此操作会产生这样的结果？

Answer 1

我只会foreach超过一个数组，因为密钥匹配问题和答案。然后，您可以引用另一个数组的键来获取当前值

foreach($_POST['custom_form']['question'] as $key => $question) {
     echo htmlentities($question . ' ' . $_POST['custom_form']['answer'][$key]) . '<br>';
}

Answer 2

如果可以假设所有字段始终存在，则应该有效：

$transposed = [];
foreach($arr['question'] as $key => $value) {
    $transposed[$key] = array('question' => $value, 'answer' => $arr['answer'][$key]);
}

但是，如果不能，则需要进行有效性检查：

$transposed = [];
foreach($arr['question'] as $key => $value) {
    if (array_key_exists($key, $arr['answer'])) {
        $transposed[$key] = array(
            'question' => $value,
            'answer'   => $arr['answer'][$key]
        );
    }
}
