上传多个文件userfile [] array？

Question

我试图上传多个图像,我有一个jquery插件设置,所以我可以浏览多个文件并选择它们.

我唯一的问题是访问我的控制器中的文件阵列,有谁知道我怎么做到这一点？谢谢.

视图:

<input type="file" name="userfile[]" id="userfile" class="multi" />

Answer 1

去年我在一个项目上遇到了同样的问题,经过一番搜索,我发现了一个完美的功能.

我不相信它,但不能记住我发现它的地方,所以如果有人知道请链接回作者.

确保表单包含这样的文件

<input type="file" name="userfile"/>
<input type="file" name="userfile2" />
<input type="file" name="userfile3" /> ..etc

要么

 <input type="file" name="userfile[]" />

功能..

function multiple_upload($upload_dir = 'uploads', $config = array())
{
    $files = array();

    if(empty($config))
    {
        $config['upload_path'] = '../path/to/file';
        $config['allowed_types'] = 'gif|jpg|jpeg|jpe|png';
        $config['max_size']      = '800000000';
    }

        $this->load->library('upload', $config);

        $errors = FALSE;

        foreach($_FILES as $key => $value)
        {            
            if( ! empty($value['name']))
            {
                if( ! $this->upload->do_upload($key))
                {                                           
                    $data['upload_message'] = $this->upload->display_errors(ERR_OPEN, ERR_CLOSE); // ERR_OPEN and ERR_CLOSE are error delimiters defined in a config file
                    $this->load->vars($data);

                    $errors = TRUE;
                }
                else
                {
                    // Build a file array from all uploaded files
                    $files[] = $this->upload->data();
                }
            }
        }

        // There was errors, we have to delete the uploaded files
        if($errors)
        {                    
            foreach($files as $key => $file)
            {
                @unlink($file['full_path']);    
            }                    
        }
        elseif(empty($files) AND empty($data['upload_message']))
        {
            $this->lang->load('upload');
            $data['upload_message'] = ERR_OPEN.$this->lang->line('upload_no_file_selected').ERR_CLOSE;
            $this->load->vars($data);
        }
        else
        {
            return $files;
        }
    } 

现在已经有一段时间了,因为我已经使用它,所以如果你需要任何额外的帮助设置它只是让我知道.
