Question

我目前有一个页面可以从MySQL数据库中动态填写调查问题（问题，答案为单选按钮/复选框）。生成的HTML看起来像这样：

  <form id="form1" name="form1" method="post" action="">
  1 . How do you classify yourself?
  <br/>
       <input type="radio" name="radio[0]" id="radio[0]" value="Alien" />Alien     
   <br />
       <input type="radio" name="radio[0]" id="radio[1]" value="Hobbit" />Hobbit     
   <br />
       <input type="radio" name="radio[0]" id="radio[2]" value="Tree" />Tree     
   <br /><br/>

  2 . Who are you?
  <br/>
       <input type="radio" name="radio[1]" id="radio[3]" value="Camel Collector" />Camel Collector     
   <br />
       <input type="radio" name="radio[1]" id="radio[4]" value="sadasd" />sadasd     
   <br />
       <input type="radio" name="radio[1]" id="radio[5]" value="Voolome" />Voolome     
   <br />
       <input type="radio" name="radio[1]" id="radio[6]" value="31231235" />31231235     
   <br />
    <br/>
  3 . Test Question
  <br/>
       <input type="radio" name="radio[2]" id="radio[7]" value="Nobody Knows" />Nobody Knows     
   <br />
       <input type="radio" name="radio[2]" id="radio[8]" value="Somebody Knows" />Somebody Knows     
   <br />
       <input type="radio" name="radio[2]" id="radio[9]" value="Who Knows" />Who Knows     
   <br />
    <br/>
  4 . Test Question 2
  <br/>
       <input type="radio" name="radio[3]" id="radio[10]" value="Answer1" />Answer1     
   <br /><br/>
  5 . First Multiple
  <br/>
      <input type="checkbox" name="Check4" value="Bike">Answer One<br>

   <br />
      <input type="checkbox" name="Check4" value="Bike">Answer Two<br>

   <br />
      <input type="checkbox" name="Check4" value="Bike">Answer Three<br>

   <br /><br/>
  6 . First Open!
  <br/>
      <input type="text" name="Ans5" />

   <br /><br/>
</form>

需要注意的一些重要事项：

有3种类型的问题，“选择” - 单选（单选按钮）; “多个” - 多项选择（复选框）; “打开” - 用户输入（文本框）。
每个元素的名称对应于相应的问题编号（问题旁边显示的数字是问题+1（因为它从0开始）。[例如，问题14将使用Radio [14]作为名称。

我的主要问题：如何提交这些字段以存储到数据库中？我想弄清楚如何编写代码，找出每个问题选择哪个选项。

方面问题：是否也可以验证这些问题以确保为每个问题选择至少一个选项？（检查textbox！=“”很简单，但我如何为单选按钮/复选框执行此操作？）

如果需要，可以提供用于生成此表单的PHP代码！它本质上是使用一个变量来存储问题编号（$ qno），它用作计数器，同时循环语句以从MySQL中提取数据，找出答案的类型，并在表单上放置适当的控件。

Answer 1

选项已选，将在您的$_POST数组和radio2中，而不是radio[2]，即使您的工作也是如此，或使用名称{{1在所有单选按钮中，您将获得包含所有选定单选按钮的数组。

此外，选中的选项应位于同一radio[]数组中的数组

您使用一个简单的名称作为复选框，这只会将最后检查的值发送到您的php脚本，并且即使检查了多个值也将作为无线电工作：

而不是$_POST，它必须是name="Check4"。

为了显示答案，您可以像这样迭代name="Check4[]"的值：

$_POST

Answer 2

做这样的事情：

<form id="form1" name="form1" method="post" action="">
1 . How do you classify yourself?
<br/>
   <input type="radio"  id="radio[0]" value="Alien" name="question1" />Alien     
<br />
   <input type="radio"  id="radio[1]" value="Hobbit" name="question1" />Hobbit     
<br />
   <input type="radio"  id="radio[2]" value="Tree" name="question1" />Tree     
<br /><br/>

2 . Who are you?
<br/>
   <input type="radio" id="radio[3]" value="Camel Collector" name="question2" />Camel Collector     
<br />
   <input type="radio"  id="radio[4]" value="sadasd" name="question2" />sadasd     
<br />
   <input type="radio"  id="radio[5]" value="Voolome" name="question2" />Voolome     
<br />
   <input type="radio"  id="radio[6]" value="31231235" name="question2" />31231235     
<br />
<br/>
3 . Test Question
<br/>
   <input type="radio"  id="radio[7]" value="Nobody Knows" name="question3" />Nobody Knows     
<br />
   <input type="radio"  id="radio[8]" value="Somebody Knows" name="question3" />Somebody Knows     
<br />
   <input type="radio"  id="radio[9]" value="Who Knows" name="question3" />Who Knows     
<br />
<br/>
4 . Test Question 2
<br/>
   <input type="radio"  id="radio[10]" value="Answer1" name="question4" />Answer1     
<br /><br/>
5 . First Multiple
<br/>
  <input type="checkbox"  value="Bike" name="question5[]">Answer One<br>

<br />
  <input type="checkbox" value="Bike" name="question5[]">Answer Two<br>

<br />
  <input type="checkbox"  value="Bike" name="question5[]">Answer Three<br>

<br /><br/>
6 . First Open!
<br/>
  <input type="text" name="question6" />

<br /><br/>
</form>

Answer 3

验证单选按钮使用此：

if($("#radio:checked").length==0)
{
  alert("Please Select atleast one");
  return false;
}

参考此Building a Simple Quiz

你可以用这个代码：

<!DOCTYPE html>

  <br/>
       <input type="radio" name="radio[]" id="radio[0]" value="Alien" />Alien     
   <br />
       <input type="radio" name="radio[]" id="radio[1]" value="Hobbit" />Hobbit     
   <br />
       <input type="radio" name="radio[]" id="radio[2]" value="Tree" />Tree     
   <br /><br/>

  2 . Who are you?
  <br/>
       <input type="radio" name="radio1[]" id="radio[3]" value="Camel Collector" />Camel Collector     
   <br />
       <input type="radio" name="radio1[]" id="radio[4]" value="sadasd" />sadasd

   <br />
       <input type="radio" name="radio1[]" id="radio[6]" value="31231235" />31231235     
   <br />
    <br/>
  3 . Test Question
  <br/>
       <input type="radio" name="radio2[]" id="radio[7]" value="Nobody Knows" />Nobody Knows     
   <br />
       <input type="radio" name="radio2[]" id="radio[8]" value="Somebody Knows" />Somebody Knows     
   <br />
       <input type="radio" name="radio2[]" id="radio[9]" value="Who Knows" />Who Knows     
   <br />
    <br/>
  4 . Test Question 2
  <br/>
       <input type="radio" name="radio3[]" id="radio[10]" value="Answer1" />Answer1     
   <br /><br/>
  5 . First Multiple
  <br/>
      <input type="checkbox" name="Check4" value="Bike">Answer One<br>

   <br />
      <input type="checkbox" name="Check4" value="Bike">Answer Two<br>

   <br />
      <input type="checkbox" name="Check4" value="Bike">Answer Three<br>

   <br /><br/>
  6 . First Open!
  <br/>
      <input type="text" name="Ans5" />

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

PHP代码

<?php if($_POST['submit']) {
    echo "<pre>";
    print_r($_POST);
    echo "</pre>";
    exit;
}
?>

<强>输出

Array
(
    [radio] => Array
        (
            [0] => Hobbit
        )

    [radio1] => Array
        (
            [0] => sadasd
        )

    [radio2] => Array
        (
            [0] => Somebody Knows
        )

    [Ans5] => 
    [submit] => Submit Query
)

提交表单中的多个字段（PHP）
