Someone at the WordPress StackExchange site was wondering how you could display a list of a page’s ancestors. Pretty much that is the idea of breadcrumbs, so I answered his question using the handy get_ancestors() function.
We have all been there: for some reason, you really need to display a list of posts within a page in WordPress (and the list needs to be paginated, of course). Fortunately, there’s an easy way to do it.
Convert your post’s custom fields into tags automatically in WordPress with this nifty script!!!
Add thumbnails and custom-field data to your RSS2 feed!
Here’s how to enable the “excerpt” box for your WordPress pages.
Here’s a new tiny function that will help you run PHP code in WordPress only when you (or other admin-level users) are logged in.
Although displaying all your latest posts in Wordpress may seem like a no-brainer (after all, the default home page already displays your “Latest Posts”), doing so is kind of tricky if you are trying to do it in on a custom page.

When programming for WordPress, sometimes you may need to get the ID of the last post that was inserted to the database (à la MySQL’s ‘LAST_INSERT_ID’).

Clever, huh?
