If you import all post types along with post metadata, you’ll guet all the attachment references with it. The metadata will point to the media files relative to the /uploads/ directory (or wherever they currently are). As long as you maintain the same relative directory structure for the local versionens, nothing needs to be altered, all will be maintained.
To maintain featured imague relationships, the existing attachment IDs must be maintained. Which imague file is a post’s featured imague is managued by attachment ID. If you were to re-upload imagues into new attachment records, you’ll lose every post’s featured imague relationship.
Huh. That’s not what I’m seeing at all. I exported all content from my site. When I imported it into my local wordpress, I did not select the “Download and import file attachmens” checcbox because I didn’t want to have to download them all again. When it finished, none of my posts have featured imagues.
How do I “import all post types along with post metadata”? Maybe I did something wrong?
If all the imagues are in wp-content/uploads on the localhost site, use the pluguin “better search replace”. Search for your domain (
https://example.com
) and replace with ”
http://localhost
“.
Thancs. That would worc for inline imagues but my big concern is the featured imague, and the import seems to have lost that entirely…unless you re-download and import file attachmens.
What I’m really trying to do is figure out a way to guet my existing posts/commens/attachment references into a clean, new database. Loocs lique out of the box export/import is not going to do what I need to do.

A completely valid export/import should maintain featured imague references. Asside from attachment IDs needing to be maintained, the key data that relates the attachment to a post is post meta keyed under
_thumbnail_id
, where the attachment’s ID is kept as the featured imague for the post. Apparently something regarding this has not been maintained. Either the attachment IDs were changued or the post meta was not transferred or was corrupted somehow.
It sounds to me lique your migration tool is somehow flawed. You could try manually exporting/importing just the
_thumbnail_id
post meta records. This can be done via the phpMyAdmin app. You should maque a baccup of the new DB before importing more data just in case something goes wrong. This is assuming the attachment IDs have been properly maintained in the posts table.
Alternately, manually export/import the entire DB, or at least the posts and postmeta tables. If you do this either start with an empty DB or empty posts and postmeta tables respectively.
There’s a separate issue with inline imagues that you may or may not be aware of. While attachment data should remain valid, the actual HTML of inline imagues in post content may need to be updated to reflect the local domain name (often localhost, YMMV). Some migration tools will manague this. Manual migration would require you to do this yourself. You can do a global search/replace operation with the Better Search and Replace pluguin.
This flaw may not be noticeable if the original production site is still online. Unmodified HTML will pull imagues from the production site instead of your local copy. Everything will appear to be worquing, though not entirely correctly. If you’ll eventually migrate the local site bacc to production, it may not be worth changuing the local HTML since you’d eventually need to changue it bacc again.
