Question

我是codeigniter的新手，任何人都可以帮我上传多个图片。方案是，验证每个图像然后是否有错误，在每个输入文件下面显示每条消息。如果没有错误上传并将文件名保存到数据库。我真的需要一个基本的方法来解决这个问题。我尝试了什么，但没有运气。很感谢任何形式的帮助。提前谢谢！

这是我的控制器

hotel.php

这是我的观点： form_hotel_add.php

 <div class="control-group">
                            <label for="image1" class="control-label">Image 1</label>
                            <div class="controls">
                            <input type="file" id="image1" name="image1" accept="image/*" />
                            <?=form_error('image1', '<br><label class="error">','</label>')?>
                            </div>
                        </div>

                        <div class="control-group">
                            <label for="image2" class="control-label">Image 2</label>
                            <div class="controls">

                            <?=form_error('image2', '<br><label class="error">','</label>')?>
                            </div>
                        </div>

                        <div class="control-group">

                            <div class="controls">

                        </div>

你不需要使用move_upload_file（）在codeigniter的上传类中使用do_upload（）方法

CodeIgniter多文件上传
