每个字段上载多个文件并使用codeigniter存储在数据库中

Question

I have a form which uploads multiple file fields into a db using codeigniter.

I need to be able to upload multiple files for each field. I understand that this could be achieved using some jquery magic, however, my problem is how do I intercept the multiple files and what is the best way to store them in my database?

At the minute I just have one field which stores the file location/name, would I need to insert all the files as one long comma seperated string? If so, how do I then make use of that string for my view functions to show each file?

Sorry if the above doesn't make sense, I can explain in more detail or post my code if required.

Thanks for any help in advance

It pains me to say this, but the best method of uploading multiple files at once is to use a plugin like Uploadify .

With regard to how you'd like to store it in the database...If you're allowing a single user to upload multiple files, I'd recommend having three tables:

1. Users (user_id, username, email, etc.)
2. Files (file_id, filepath, time_uploaded, etc.)
3. Users_files (user_id, file_id)

Then when you store the files on your server, you can insert a new row into your "files" table. Then when you delete files, be sure to remove the row in the files table and the association in the users_files table.
