WordPress Development Stack Exchange is a question and answer site for WordPress developers and administrators. It's 100% free, no registration required.

Each post has an ID and I would like to know how they were assigned. Is there a pattern? Why are the ID's not being incremented by 1 every posts? It would be easier..My ID's go from 9867, to 9869, to 9864, etc.. I can't seem to find a pattern.

I could use "The Loop", but I'm doing that from another site. I want to include the last 30 posts of my wordpress site, so I need to find a pattern in the url to get the last 30 posts.

Each auto-draft gets its own ID, each revision, each nav item, page, custom post type …

The actual ID of a post should be irrelevant, this is really just needed for the database and ugly permalinks.

You cannot get the last 30 items by inspecting the post ID only.

Install a REST API on the other site and a rule to get the last x items.

Then how can I retrieve the last 30 items from an external domain? –  Maxwell Apr 10 '13 at 15:22
    
@Maxwell See my update. –  toscho Apr 10 '13 at 15:24
    
Thank you. It looks like a very complicated solution though. –  Maxwell Apr 10 '13 at 15:25

If you take my code it is done in less than 20 minutes. Really not that complicated. :) –  toscho Apr 10 '13 at 15:26
    
20 mins for you, @toscho :) –  vancoder Apr 10 '13 at 16:56

Use the RSS feed - typically at http:/sitename/feed.

You can set the number of items the fed contains by changing the value Syndication feeds show the most recent in Settings > Reading

This is a very vague 'answer'. –  vancoder Apr 10 '13 at 16:55
