如何在另一个php页面中获取多个单选按钮值？

Question

I have multiple questions and each question has 4 answers, I display all questions and their answers in PHP, by:

 while($row=mysqli_fetch_array($rs)) 
  {
   echo "question:".$row['question']."<br>";
  ?>
   <input type="hidden" name="id[<?php echo $row[id] ?>]" value="<?php echo $row[id]    ?>" />
  <?php echo $row['op1'] ?>
  <input type="radio" name="opt[<?php echo $row['id'] ?>]" value="<?php echo $row['op1'] ?>-<?php echo $row['id'] ?>" /><br>
   <?php echo $row['op2'] ?>
  <input type="radio" name="opt[<?php echo $row['id'] ?>]" value="<?php echo $row['op2'] ?><?php echo $row['id'] ?>" /><br>
  <?php echo $row['op3'] ?>
  <input type="radio" name="opt[<?php echo $row['id'] ?>]" value="<?php echo $row['op3'] ?><?php echo $row['id'] ?>" /><br>
  <?php echo $row['op4'] ?>
   <input type="radio" name="opt[<?php echo $row['id'] ?>]" value="<?php echo $row['op4'] ?><?php echo $row['id'] ?>" /><br>

 <?php
  }

 ?>
  <input type="submit"  value="answer" /><br>

How can I get radio button value for each $row['id'] on the next page.

Answer 1

use form action as your redirection page and method POST or GET as you prefer, then try

print_r($_POST);// as your method and you could use $_REQUEST

for GET method

print_r($_GET);

you will see radio button value in array,...

if we use $_GET method as form attribue then we will retrieve form value by $_GET if we use $_POST method as form attribue then we will retrieve form value by $_POST

and $_REQUEST can retrieve value posted by both method, but Request is not a method
