I get a ‘*Warning: file_get_contents … : failed to open stream: HTTP request failed! HTTP/1.0 403 Forbidden*’ Error in my logs and no books are displayed. Why is this happening?
Your web-site has been configure not to allow outgoing HTTP requests and you have ‘Use Google API’ enabled.
Please de-select the ‘Use Google API’ option to use the direct connection instead.
I get a ‘*No Google Books Entry Found for ISBN:NUMBER*’ on my Blog… Why?
Sometimes Google Books does not return any valid responses on ISBNs. Try the following:
- See if you can find an alternate ISBN for the book
- Toggle the “Use Google API” option
- Find the eBook on Google’s Books Web Page and use its ISBN
Are you planing to insert other sources than Google Books to the Currently Reading widget?
I’ll have a look into supporting Amazon, though they do make you jump through hoops to use their API (which is the reason I settled on using Google Books to start with).
Is there a way to get this plugin to do a library of all of your books into WordPress?
It’s not currently possible with this plugin, no.
I’ll give it a bit of thought and see if I can extend it to do that; but it will most likely need the creation of an alternate plugin to do that.
This would likely require its own database table to do properly, as well…
