Question

For a multiple choice quiz application i would like to show the dummy answers with the correct answer. But with the correct answer being in a different position at each different question.

This is what i’ve tried but it doesn’t seem to be working:

if ($question->type == 1)
            {   

                echo "<div id='dummy_answers'>";
                //Show Dummy
                echo '<h3>Dummy Answers</h3>';
                //Get Dummy Answers
                $query = $this->test_model->getDummyAnswers($question->id);
                $dummy_num = 1;
                foreach ($query->result() as $row)
                {
                    $rand_number = rand(1, 3);
                    if ($dummy_num == $rand_number)
                    {
                        $dummy_num = $rand_number + 2;
                        echo '<h4>Answer '.$dummy_num.'</h4>';
                        echo '<p>';
                        echo $row->option;
                        echo '</p>';
                        //Now echo the real answer
                        echo '<h4>Answer '.$rand_number.'</h4>';
                        echo '<p>';
                        echo $row->option;
                        echo '</p>'; //Get id's for each.echo $row->id;         
                    }
                    else
                    {
                        echo '<h4>Answer '.$dummy_num.'</h4>';
                        echo '<p>';
                        echo $row->option;
                        echo '</p>';
                        $dummy_num++;
                    }
                }
                echo '</div>';
                echo '  <hr/>';
            }
        ?>

You should use shuffle function.
In your case it will be:

if ($question->type == 1)
  { 
    echo "<div id='dummy_answers'>";
    //Show Dummy
    echo '<h3>Dummy Answers</h3>';
    //Get Dummy Answers
    $query = $this->test_model->getDummyAnswers($question->id);
    $answers=$query->result();
    shuffle($answers);
    foreach ($answers as $nr=>$row)
    {
        echo '<h4>Answer '.($nr+1).'</h4>';
        echo '<p>';
        echo $row->option;
        echo '</p>';
    }
    echo '</div>';
    echo '  <hr/>';
  }
?>
