选择单选按钮时，从隐藏输入字段中检索值

Question

I have a table name courses

courses('course_id','course_name','course_desc')

I am using php. I have 2 rows of record in this table. And I have used a while loop to list the two as radio button options. I want to add a hidden input field that posts the related course_id to the course selected in the radio button. What I have right now is.

 while($row = mysql_fetch_assoc($result)){
          echo '<td><input type="hidden" name="courseid" value="'.$row['course_id'].'"><strong class="panel-title">'.$row['coursename'].'</strong> - '.$row['course_desc'].'<br><input type="radio" name="'.$row['coursename'].'" value="'.$row['coursename'].'"> - Choose '.$row['coursename'].'</td></tr>';

The related hidden input wont get selected when I select 1 of the course. How to achieve that. I hope it would be possible without use of jquery as much as possible.

Answer 1

You should put that course_id in value of radio field, so that you will get it posted with your form and by that course_id you can easily retrieve course_name

while($row = mysql_fetch_assoc($result)){
      echo '<td>'.
               '<strong class="panel-title">'.$row['coursename'].'</strong> - '.
                $row['course_desc'].'<br><input type="radio" name="'.$row['coursename'].'" value="'.$row['course_id'].'"> '.
               '- Choose '.$row['course_name']
           .'</td>';

OR

If you want to have course_name as well then you can change your value to something like this

... value="'.$row['course_id'].'-'.$row['course_name'].'" ...

and then you can easily break it to get course_id and course_name in PHP or JavaScript
