通过HTML表单向数据库添加问题时选择正确的答案

问题描述：

I have a form which has the question and 4 answers (it's a quiz), I tried to comment on https://stackoverflow.com/a/29280091/6482242 but I don't have enough reputation yet. This is very similar to what I have (as well as How to set the correct answer via checkbox? ).

The layout that I have is:

<label for="question_text">Question Text:</label>
<textarea title="Insert Question Text" name="question_text"></textarea>

<h4>Check Correct answer -></h4>
<input type="radio" name="correct_answer_flag" value="1">
<label for="correct_answer_flag, answer_1">Answer One:</label>
<input type="text" title="Enter Answer" name="answer_1" />
<br />
<br />
<input type="radio" name="correct_answer_flag" value="1">
<label for="correct_answer_flag, answer_2">Answer Two:</label>
<input type="text" title="Enter Answer" name="answer_2" />
<br />
<br />
<input type="radio" name="correct_answer_flag" value="1">
<label for="correct_answer_flag, answer_3">Answer Three:</label>
<input type="text" title="Enter Answer" name="answer_3" />
<br />
<br />
<input type="radio" name="correct_answer_flag" value="1">
<label for="correct_answer_flag, answer_4">Answer Four:</label>
<input type="text" title="Enter Answer" name="answer_4" />
<br />
<br />
<input type="submit" value="Submit Question" name="question_submit" />

There is some PHP in the background to grab these and put them into a database, but I need to know please what the correct syntax is to link a radio button to a text input?

Thanks in advance :D

我有一个有问题和4个答案的表格（这是一个测验），我试着评论 https://stackoverflow.com/a/29280091/6482242 但我还没有足够的声誉。这与我的非常相似（以及如何通过复选框设置正确答案？）。 p>

我的布局是： p>

 ＆lt; label for =“question_text”＆gt;问题文本：＆lt; / label＆gt;  
＆lt; textarea title =“插入问题文本”name =“question_text”＆gt;＆lt; / textarea＆gt; 
 
＆lt; h4＆gt;检查正确答案 - ＆gt;＆lt; / h4＆gt; 
＆lt; input type =“radio”  name =“correct_answer_flag”value =“1”＆gt; 
＆lt; label for =“correct_answer_flag，answer_1”＆gt;答案一：＆lt; / label＆gt; 
＆lt; input type =“text”title =“Enter Answer”name =  “answer_1”/＆gt; 
＆lt; br /＆gt; 
＆lt; br /＆gt; 
＆lt; input type =“radio”name =“correct_answer_flag”value =“1”＆gt; 
＆lt; label for =“correct_answer_flag，  answer_2“＆gt;答案二：＆lt; / label＆gt; 
＆lt; input type =”text“title =”输入答案“name =”answer_2“/＆gt; 
＆lt; br /＆gt; 
＆lt; br /＆gt; \  n＆lt; input type =“radio”name =“correct_answer_flag”value =“1”＆gt; 
＆lt; label for =“correct_answer_flag，answer_3”＆gt;答案三：＆lt; / label＆gt; 
＆lt; input type =“text”  title =“输入答案”name =“answer_3”/＆gt; 
＆lt; br /＆gt; 
＆lt; br /＆gt; 
＆lt; input type =“radio”name =“correct_a  nswer_flag“value =”1“＆gt; 
＆lt; label for =”correct_answer_flag，answer_4“＆gt;答案四：＆lt; / label＆gt; 
＆lt; input type =”text“title =”输入答案“name =”answer_4“  /＆gt; 
＆lt; br /＆gt; 
＆lt; br /＆gt; 
＆lt; input type =“submit”value =“提交问题”name =“question_submit”/＆gt; 
  code>  pre>  
 
 后台有一些PHP要抓住这些并将它们放入数据库，但我需要知道将单选按钮链接到文本输入的正确语法是什么？ p> \  n 
 
提前致谢：D  p>

答

You should change the values of radio buttons and then store its value to a separate column in table with column something like correct_answer

<label for="question_text">Question Text:</label>
<textarea title="Insert Question Text" name="question_text"></textarea>

<h4>Check Correct answer -></h4>
<input type="radio" name="correct_answer_flag" value="1">
<label for="correct_answer_flag, answer_1">Answer One:</label>
<input type="text" title="Enter Answer" name="answer_1" />
<br />
<br />
<input type="radio" name="correct_answer_flag" value="2">
<label for="correct_answer_flag, answer_2">Answer Two:</label>
<input type="text" title="Enter Answer" name="answer_2" />
<br />
<br />
<input type="radio" name="correct_answer_flag" value="3">
<label for="correct_answer_flag, answer_3">Answer Three:</label>
<input type="text" title="Enter Answer" name="answer_3" />
<br />
<br />
<input type="radio" name="correct_answer_flag" value="4">
<label for="correct_answer_flag, answer_4">Answer Four:</label>
<input type="text" title="Enter Answer" name="answer_4" />
<br />
<br />
<input type="submit" value="Submit Question" name="question_submit" />

And in that column just store the number of the selected Radio. So with each question, you will be storing 4 options, and among those 4 there will be one correct answer and its index will be stored in a separate table where you store you answer options.
