在codeigniter中的同一网页上传和查看多个图像

Question

此图显示了我需要对 codeigniter 执行的操作。我有一个页面有几个div标签。我需要上传图片并在同一个地方展示。但是应该有3个不同的图像和3个不同的文件位置来保存这些图像。我尝试了很多方法。请有意见的人帮助我。

我的控制器

 <?php
        if (!defined('BASEPATH'))
            exit('No direct script access allowed');
        class Upload_Controller extends CI_Controller

我的观点

<div id="1">
<?php echo form_open_multipart( 'upload_controller/do_upload');?>
<?php echo "<input type='file' name='userfile' size='20' />"; ?>
<?php echo "<input type='submit' name='submit' value='upload' /> ";?>
<?php echo "</form>"?>
</div>
<div id="2">

<h3>Your file was successfully uploaded!</h3>
    <!-- Uploaded file specification will show up here -->
    <ul>

            <li>


            </li>
            <img alt="Your uploaded image" src="<?=base_url(). 'uploads/' . $upload_data['file_name'];?>">

    </ul>
</div>

<div id="3">

<?php echo form_open_multipart( 'upload_controller/do_upload2');?>
<?php echo "<input type='file' name='userfile' size='20' />"; ?>
<?php echo "<input type='submit' name='submit' value='upload' /> ";?>
<?php echo "</form>"?>
</div>

<div id="4">

    <h3>Your file was successfully uploaded!</h3>
    <!-- Uploaded file specification will show up here -->
    <ul>

            <li>


            </li>

试用此代码：

model name

这里是控制器代码：

<form method="post" action="uploader/go" enctype="multipart/form-data">
    <input type="file" name="image1" /><br />
    <input type="file" name="image2" /><br />
    <input type="file" name="image3" /><br />
    <input type="file" name="image4" /><br />
    <input type="file" name="image5" /><br />
    <input type="submit" name="go" value="Upload!!!" />
</form>

} }
