Newbie questions: How do I install this in Wordpress? Does it work with PHP 7+?

@KimberH that doesn't work on PHP. This 10 years old snippet is intended to run on Django framework, which is written in Python. I'm not sure on WordPress. Google for wp_handle_upload_overrides and check what you get.

Thanks! Helped me fix my problem quickly.

Here’s a sidenote: The original get_available_name method e.g. does a check for suspicious file operations and max_length. To benefit from the original method, call super():

storage.py

from django.core.files.storage import FileSystemStorage


class FileSystemOverwriteStorage(FileSystemStorage):
    """
    Custom file system storage: Overwrite get_available_name to make Django replace files instead of
    creating new ones over and over again.
    """
    def get_available_name(self, name, max_length=None):
        self.delete(name)
        return super().get_available_name(name, max_length)

… and in settings.py:

# …
DEFAULT_FILE_STORAGE = '<my-app>.storage.FileSystemOverwriteStorage'
