Codeigniter多文件上传路径

// this is for form field 1 which is an image....
$config['upload_path'] = './uploads/path1';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->upload->initialize($config); 
$this->upload->do_upload($fieild_1);

// this is for form field 2 which is a pdf
$config['upload_path'] = './pdfs/path2';
$config['allowed_types'] = 'pdf';
$config['max_size'] = '300';
$this->upload->initialize($config); 
$this->upload->do_upload($fieild_2);

我在这里写了一整篇文章: http://taggedzi.com/articles/display/multiple-file-uploads-using-codeigniter

您可以更改第二个初始化脚本中允许的任何参数,以便第二个文件的组成完全不同。您可以随意多次执行此操作,只需为每种文件类型重新初始化即可。(您甚至可以设置一个配置数组,如果您愿意的话,还可以进行循环…)

希望这有帮助。

/images/member/1
/images/member/2
/images/member/3

我的控制器根据用户id动态设置上传目录

$config['upload_path'] = "/images/member/$user_id";

第二,你需要处理你上传的文件,创建大小和缩略图图像。我的图像处理库使用与传递给$config['upload\u path']的路径相同的路径作为其根目录,并将其输出放置到相对于该动态根目录的子目录中:

/images/member/1/resized
/images/member/1/thumbnails

我的网站其实比这要复杂一点。但关键是动态设置$config['upload\u path']可以让您拥有任意多的上传路径。

简短的(令人失望的)回答是:CodeIgniter的文件上传类设计为每个表单接受一个上传的文件。
