(PHP) Geo Mashup post query contextual map

Wed, 28 Jul 2010 02:51:41 GMT

Geo Mashup contextual maps display the results of a WordPress query, so they can be very useful in combination with the WordPress `query_posts` function. This example maps post with an example tag, but any call to `query_posts` could be substituted. This is code that would go in a WordPress template.

This makes template code that applies to children of a particular page much more readable, especially if you can use a page path instead of an ID: `if ( is_child_of( 'topic/subtopic' ) ) :`.

Get the ID of the root (oldest ancestor, parent without parents) page relative to the current page in a WordPress page template. Can be helpful for use with wp\_list\_pages() to create navigation markup.

(jQuery) jQuery: select first and/or last list items

Mon, 17 Aug 2009 17:14:01 GMT

Select the first and last item in an unordered list. As an example, I add a CSS class to each. In WordPress, it's not so easy to get wp\_list\_pages() to generate these classes. jQuery provides an easy out for javascript-enabled clients.

(PHP) Wordpress: Does a page have children?

Mon, 17 Aug 2009 11:20:03 GMT

There's no has\_children() function in WP 2.8.4, but get\_children() returns false if the post/page has no children, so it can serve the same purpose in a page template. Outside a page template you'd have to add a global declaration for the $post variable.
