Need to send an Ajax request to a Solr server that’s on a different domain? You will, of course, need to use JSONP instead of an ordinary JSON request, due to JavaScript’s cross-domain security restrictions. To get a properly padded response from Solr, add the json.wrf parameter to your query string, giving it the name of your callback function. In jQuery:
jQuery.ajax({
url: mySolrUrl,
data: myQueryParameters,
success: mySuccessCallback,
dataType: 'jsonp',
jsonp: 'json.wrf'
});Of course, for this to work the Solr server you’re accessing needs to be publicly accessible, which probably isn’t ideal for security.
WordPress lets you create excerpts for Posts, but not for Pages. Generally, that makes good sense. If you need excerpts for pages, though, it’s pretty simple to add.
function my_init() {
add_post_type_support('page', array('excerpt'));
}
add_action('init', 'my_init');That’s all there is to it. Works with WordPress 3.0+.
Update 2010-10-01: Hey, look, I made it into a plugin.
As of version 6.14, Drupal works with PHP 5.3, but many essential modules still issue warnings (usually due to passing expressions by reference). If your Ubuntu 10.04 (Lucid Lynx) server is running 5.3, this script will automate the downgrade to the latest 5.2 by telling aptitude to use the source lists for Ubuntu 9.10 (Karmic Koala).
Thanks to Nick Veenhof, mrkandy, and their many commenters, from whom this script is derived.

There’s one primary distinction between Drupal and WordPress. In Drupal, URLs map to PHP functions. In WordPress, URLs map to documents (or, quite often, collections of documents). The former can certainly be powerful and easy to work with. The latter, once you get used to the paradigm, can provide an incredible simplicity, powerful in its own way.
I was building a website today that has a location-based search component. Basically, I have a collection of posts with addresses, and I need to be able to search for addresses within a given distance of a queried address, and sort them by said distance. To be honest, that’s hard to do with WordPress. But it is possible…

Building on my previous post about creating archive pages for custom post types, there’s another piece to add to the puzzle.
You archives pages will use the default index.php template. If you want to use a different template, you’ll need to hook into the template_redirect action to specify your template file. I like to use a file name like type-MY_POST_TYPE.php (although that’s easily changed), using the function below.
