Filters

The importer has a couple of filters to allow you to completely enable/block certain features:

• import_allow_create_users: return false if you only want to allow mapping to existing users
• import_allow_fetch_attachments: return false if you do not wish to allow importing and downloading of attachments
• import_attachment_size_limit: return an integer value for the maximum file size in bytes to save (default is 0, which is unlimited)

There are also a few actions available to hook into:

• import_start: occurs after the export file has been uploaded and author import settings have been chosen
• import_end: called after the last output from the importer

Latest changelog entry

• Skip the _wp_attachment_edit_root_id meta key on import. It stores an attachment ID from the source site, and attachment IDs change on import, so the imported value could point at an unrelated attachment on the destination site.
