filefield

问题 I want to localize a form in my app so that all the labels are in Finnish. This is easy with all other form components, but how do I do this with a file field?

问题 I am looking for a way to rename files that are uploaded by users through a filefield. For example, rename user profile photos using uniqid . I found a good solution for D6 at "Drupal 6: How to Change Filename on Upload" but can't find anything for D7.

问题 I am using the model with FileField to deal with file uploading. Now the files can be uploaded successfully. However, there is one more small improvement I want to make, which is to create folder for the user with the username.
