In my database I have multi exam papers, for each paper, there are some multiple-choice questions that users have to answer. I use a multi-step form and put every question in one step.
I want to catch user answers but, I am unable to post their answers on the results.php page, please help.
/* Here is the HTML form Code*/
<form id="regForm" action="results.php">
<?php
if(!empty($_GET['id'])){
$id = $_GET['id'];
$fetchtarget = mysqli_query($conn, "select * from exam_paper where examPaperID= '$id' ");
$row= mysqli_fetch_assoc($fetchtarget);
$fetchquestion = mysqli_query($conn, "select * from question where examPaperID= '$id' ORDER BY questionID ");
while($row1= mysqli_fetch_assoc($fetchquestion)){
?>
<!-- One "tab" for each step in the form: -->
<div class="tab"><?php echo $row1["question_statment"]; ?> <br>
<section>
<?php
$fetchchoices = mysqli_query($conn, "select * from choice where questionID= '".$row1["questionID"]."' ORDER BY choiceID ");
while($row2= mysqli_fetch_assoc($fetchchoices)){
?>
<div class="radio-container">
<input type="radio" name="options" id="options" value="<?php echo $row2["choiceStatment"]; ?>" oninput="this.className = ''" required>
