使用CodeIgniter通过FTP上传文件

Question

I am trying to upload a file using the FTP class in CodeIgniter. For that I have written the following:

        $this->load->library('ftp');

        $config['hostname'] = '127.0.0.1';
        $config['username'] = 'localftp';
        $config['password'] = '';
        $config['debug'] = TRUE;

        $this->ftp->connect($config);

        $this->ftp->upload($_FILES['book_file']['tmp_name'], asset_url()."books/" . $_FILES['book_file']['name'], "ascii", 0775);

        $this->ftp->close();

but it is showing me :

Unable to upload the specified file. Please check your path.

I am using XAMPP FileZilla to connect to my FTP host. For that I have created the user localftp with no password. And this user has all the permissions on the host.

and this is my local XAMPP server logging:

  (000016)24-Dec-13 23:27:05 PM - localftp (127.0.0.1)> disconnected.

on the second last line it is saying 550 filename invalid.. I think this is my problem.. Please can any one help me out to solve this issue..

Answer 1

It's right there in the log:

(000016)24-Dec-13 23:27:05 PM - localftp (127.0.0.1)> STOR http://localhost/International/public/books/ftpupload.pdf

You are trying to name the file

http://localhost/International/public/books/ftpupload.pdf

which is not a valid filename.

Try removing asset_url():

$this->ftp->upload($_FILES['book_file']['tmp_name'], "books/" . $_FILES['book_file']['name'], "ascii", 0775);
