目前，我有一些代码可以执行以下操作：
我可以编辑，我可以为这个特定的房子添加上传/编辑一个图像的房屋销售，然后在创建过程中创建缩略图，然后将原始文件名和缩略图名称保存到名为
（注意：添加和编辑单独的页面）
我的想法是：
我将创建另一个页面，其中包含已放入下拉菜单中的房屋名称，因此当选择一个并选择图像时，它们将上传。
我的问题是：
我对于修改数据库以实现此更改的最佳方法感到困惑。
如何修改我的PHP代码以处理多个文件（如何处理多个图像然后传递图像以上传大小调整等）什么是最佳选项？ - 在我的想法中？
我可以举一个例子来说明我应该做些什么来解决这个问题。
我已添加了我的添加促销的模型视图和控制器（作为示例），但我还需要为相应的销售编辑图像。

对于处理下拉列表，我认为这很简单。但相关的多上传内容，你可以使用类似的东西......
在您的视图中
<?php echo form_label('Image: ','userfile1');?>
<?php echo form_upload('userfile1');?>
<?php echo form_label('Image: ','userfile2');?>
<?php echo form_upload('userfile2');?>
<!-- and so on -->
<span class="small">Required Field - 1MB Max Size</span>
然后在你的控制器中，你可以这样做
//Set File Settings
$config['upload_path'] = 'includes/uploads/sales/';
$config['allowed_types'] = 'jpg|png';
$config['remove_spaces'] = TRUE;
$config['overwrite'] = TRUE;
$config['max_size'] = '1024';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('upload', $config);
// Validate files for upload section...
$success = array();
$errors = array();
$updload_files = array(
'userfile1' => $_FILES['userfile1'],
'userfile2' => $_FILES['userfile2'],
// You can add more
);
foreach($updload_files as $field => $updload_file)
{
// Only process submitted file
if($updload_file['error'] == 0)
{
// If there is an error, save it to error var
if( ! $this->upload->do_upload($field) )
{
$errors[] = 'Failed to upload '.$field;
}
// Use this to get the new file info if you need to insert it in a database
$success[] = array( 'Success to upload '.$field => $this->upload->data());
}
else
{
$errors[] = $field . ' contain no data';
}
}
// Heres you could gettin know whats happen
var_dump($errors);
var_dump($success);
