I’ve been running a WordPress site for over a year now and never had a problem with it until yesterday. I’m using a custom field to store the url to a preview image for every post. I simply add it using the standard Custom Fields form in the Edit Post screen. Before when I’d save the post as a draft or if I immediately published it the custom field would be saved. But now all of a sudden no matter how I save the post (save as draft, publish or auto-save) the custom field isn’t being stored in the database. I did confirm this by checking the wp_postmeta table.
I already reinstalled WordPress, but it doesn’t change a thing. I also went through other similar posts about this subject, but none of the solutions work.
Any ideas?
So after digging deeper, I figured out the custom field was dependent on another field. Still not sure why it wouldn’t store the custom field in the database even though the other field wasn’t filled out first. But it works anyway when I do it that way. WordPress works in mysterious ways sometimes.
