php - 选择选项默认值中的 Codeigniter 不起作用

Question

嗨，我是 Codeigniter 的初学者。以下是我的代码。问题是，它不会在选择意见菜单中显示默认值。请帮忙，谢谢。

<select name="taskOption1" class="form-control">
    <option value="" disabled selected> -- select an option -- </option>
    <?php
        foreach($stagesData as $key => $value):
            echo '<option value="'. $value -> stage_id . '"' .
            set_select('taskOption1', $rows[0] -> stage_reject_id) . '>' . $value -> stage_name . '</option>';
        endforeach;
     ?>
</select>

<select name="taskOption2" class="form-control">
        <option value="" disabled selected> -- select an option -- </option>
        <?php
            foreach($rejectsData as $key => $value):
                echo '<option value="'. $value -> reject_id . '"' .
                set_select('taskOption2', $rows[0] -> stage_reject_id, ((($value -> reject_id) == ($rows[0] -> reject_id))?true:false)) . '>' . $value -> reject_name . '</option>';
             endforeach;
        ?>
</select>
