下面的代码是用于显示不同类型问题及其选择的视图页。。填空和多答案等问题由多个答案元素组成。

<?php echo form_open('courseware/saveanswer'); ?>
<?php if(count($test_questions)):?>
<?php $i = 1 ?>
<ol>
   <?php foreach($test_questions as $test_question):?>
 <li>
<?php if($test_question->question_type == 'Fill-blanks'):?>
    <?php $test_question->question_text = str_replace('___',form_input(array('name'=>'answer[]','id'=>'answer_'.$i++,'type'=>'text','size'=>'8')),$test_question->question_text)?>
<?php endif ?>
    <?php echo $test_question->question_text ?>
    <?php if($test_question->question_type == 'Multi-choice'):?>
        <?php $choices = explode("\n", $test_question->question_choices)?>
        <?php if(count($choices)):?>
            <ul>
            <?php foreach($choices as $choice):?>
                <li><?php echo form_radio('answer'.$test_question->question_id,$choice) ?> <?php echo $choice ?></li>
            <?php endforeach ?>
            </ul>
