I am curently working on a file-sharing application which allows regsitered users to upload files onto the server.
Information about the files are stored in a database.

The problem I am having is stopping a file from being uploaded if the user has reached their upload limit. The users table in the database contains a set amount of space for each user. How can I ensure that they canot upload a file if they will go over their limit?

I would even be happy if someone could show me how I could simply delete the file after upload if the limit is reached.

Thanks for the help.

In your users table, you could create a field called used_diskspace. Every time a user loads up a file, you add the filesize to that field. Every time a user deletes one of his files, you substract it from that field.

So, when a user uploads a new file, you take the size of that file and check whether he has still enough diskspace left. If not, show an error, else continue the upload.

Makes sense?

hm, if I remember correctly, if you don´t call the php function move_uploaded_file() then the file will remain in the tmp folder and will be deleted automacially…
so just don´t call the CI upload library or move_uploaded_file() and it should be enough…

Yeah that’s what I am doing I was just wandering if there was anything in CI that would let me cancel an upload but obviously not. Thanks for the info.

You’re right. The file will be deleted from the temporary directory at the end of the request if it has not been moved away or renamed.
