ISBN doesn't save – No display book

If anyone of you knows how can I subscribe to these forums whenever one of you submits a new bug, I’d be grateful … 😀

I’m checking it out now …

That’s not the fix….

I have tried a valid ISBN against the Google Books API
http://www.google.com/books/feeds/volumes/?q=9781559351201

9781559351201 = Lord of the Rings, and it validated against the API.

The same issue is still valid. The problem is that the ISBN is not saved in the database at all. After you hit save, the ISBN field is reset.

Tested on WP 3.4.2 and 3.5 as well.

Yes the book is shown in that search, but if you call the public API with the ISBN number:

https://www.googleapis.com/books/v1/volumes?q=9781559351201

I only get

{
 "kind": "books#volumes",
 "totalItems": 0
}

as a response. And I don’t know of any other way to get a book from the Google Books API.

If you try other ISBNs (completely random):

9781133776574
9780307588364

…

These show a valid response in the form of:

}

So I don’t know a way around this, except another version of the book with a different ISBN. The values are saved in the database only if the response is valid. So the problem isn’t in the code itself.

The issue is now fixed.

If a book is not in the Google Books or OpenLibrary APIs an error message is shown.
