php - Prevent submit button from duplicate in form -


i'm generating form questions stored in database. don't understand how can prevent submit button duplicate every row (question)? want 1 submit button in end of form.

// generate questions $query = "select * questions"; $result = @mysqli_query($con, $query);  if ($result) { while($row = mysqli_fetch_array($result, mysqli_assoc)) {      $body = $row['question_body'];     $question_id = $row['question_id'];      echo '           <tr>             <form action="insert.php" method="post">                 <td><input type="hidden" name="question_id" value="'.$question_id.'">'.$question_id, $body.'</td>                 <td><input type="radio" name="answer_value" value="1"></td>                 <td><input type="radio" name="answer_value" value="2"></td>                 <td><input type="radio" name="answer_value" value="3"></td>                 <input type="submit">          </tr>              </form>                         <br/>'; }

you'll need move submit button outside of while loop. (as side note, prefer alternative syntax control structures.)

<? // generate questions $query = "select * questions"; $result = @mysqli_query($con, $query); if ($result) : ?> <form action="insert.php" method="post">     <table> <?     while($row = mysqli_fetch_array($result, mysqli_assoc)) :         $body = $row['question_body'];         $question_id = $row['question_id']; ?>         <tr>             <td><input type="hidden" name="question_id" value="<? echo $question_id ?>"><? echo $question_body ?></td>             <td><input type="radio" name="answer_value" value="1"></td>             <td><input type="radio" name="answer_value" value="2"></td>             <td><input type="radio" name="answer_value" value="3"></td>         </tr> <?     endwhile; ?>         <tr>             <input type="submit">         </tr>     </table> </form> <? endif; ?>
