下午好!所以,我在这里遇到了我的PHP代码的一些问题。 我不完全确定为什么,但按下提交按钮后,没有信息发送到$ _POST。任何推理为什么这是?

发送到html文档的数据被写入到php多维关联数组中。

我的代码张贴如下。

<html> 
<?php 
$pageId = "Quiz"; 
$questions = array(
    array('question' => 'How do you install Apache2 on Debian?', 
     'answer' => 'sudo apt-get install apache2', 
     'choices' => array('1' => 'apt-get update', '2' => 'sudo apt-get install apache2', '3' => "sudo apt-get install apache", '4' => 'apt-get install apache2',), 
    ), 
    array('question' => 'What command enables ufw?', 
     'answer' => 'sudo ufw enable', 
     'choices' => array('1' => 'sudo ufw allow', '2' => 'sudo ufw enable 80', '3' => 'ufw allow', '4' => 'sudo ufw enable',), 
    ), 
    array('question' => 'What ports do you keep open to ensure your web content can be driven?', 
     'answer' => '80 and 443', 
     'choices' => array('1' => '80 and 443', '2' => '88 and 441','3' => "80 and 4443", '4' => '90 and 433',), 
    ), 
    array('question' => 'What OS was this tutorial tailored for?', 
     'answer' => 'Debian', 
     'choices' => array('1' => 'Debian', '2' => 'Ubuntu','3' => 'CentOS', '4' => 'FreeBSD',), 
    ), 
    array('question' => 'What are some of the benefits to setting up your own web server?', 
     'answer' => 'choice 1 data', 
     'choices' => array('1' => 'choice 1 data', '2' => 'choice 2 data',), 
    ), 
); 
include 'includes/header.html.php'; 
echo '<pre>'; 
print_r($_POST); 
echo '</pre>'; 
?> 

<div class="container" id="theBestStuff"> 
    <main> 
     <form> 
      <ol> 
<?php foreach ($questions as $q => $question) : ?> 
       <li><?= $question['question']?></li> 
<?php foreach ($question['choices'] as $c => $choice) : ?> 
       <label><input type="radio" name="question<?= $q ?>" value="<?= $choice ?>"><?= $choice ?></label> 
<?php endforeach; ?> 
<?php endforeach; ?> 
      </ol> 
      <input class="btn btn-info" action="" method="post" type="submit" value="submit"> 
     </form> 
    </main> 
</div> 

<?php 
include 'includes/footer.html.php'; 
?> 
</html>

形式use the GET method by default。您必须在<form>标记上明确设置method="post"以便浏览器将请求作为POST提交并填充超全球$_POST<input>标签上的method属性没有意义,因为有关将数据发送到服务器的详细信息在整个表单中应用。

我的天哪,你说得对!我知道。一些非常简单的... 即使经过数小时的故障排除,您也可以忽略其中一件事。 –

这将是因为您的<form>标记在其中没有任何属性。它应该已经:

<form action="php_script_to_process_the_form.php" method="POST"> 

    ... Form elements ... 

    <input class="btn btn-info" type="submit" value="submit"> 

</form> 

参考标签上W3Schools的所有可用的属性列表,它可能需要:https://www.w3schools.com/tags/tag_form.asp

方法=“GET”是方法属性的默认值,它追加表单数据在名称/值对的网址:URL名=值&名=值

然而,

方法? =“POST”的形式发送数据作为HTTP交易后

而且,

动作=“URL”指定在提交表单时向何处发送表单数据。该URL可以是绝对的:行动= “http://www.example.com/example.php”或相对:行动= “使用example.php”
