使用HTML表单隐藏元素传递数组 [英] Passing an array using an HTML form hidden element

问题描述

我正在尝试在隐藏字段中发布数组，并希望在用PHP提交表单后检索该数组.

I am trying to post an array in a hidden field and want to retrieve that array after submitting a form in PHP.

$postvalue = array("a", "b", "c");
<input type="hidden" name="result" value="<?php echo $postvalue; ?>">

但是在打印发布的值后，我只能得到一个数组字符串.那我该怎么解决呢?

But I am getting only an array string after printing the posted value. So how can I solve it?

推荐答案

使用:

$postvalue = array("a", "b", "c");
foreach($postvalue as $value)
{
    echo '<input type="hidden" name="result[]" value="'. $value. '">';
}

然后您将获得$_POST['result']作为数组.

And you will get $_POST['result'] as an array.

print_r($_POST['result']);
