Wrote this quick WordPress code snippet at WordCamp Louisville. It makes a /random/ URL on your site which redirects to a random post. Thought some people might find it useful.
Not a perfect little snippet, but gets the job done. Note the use of the little-used 307 redirect for temporary redirection. This is to make browsers not cache the results of the redirect, like some of them might do with a 302.
add_action('init','random_add_rewrite');
function random_add_rewrite() {
global $wp;
$wp->add_query_var('random');
add_rewrite_rule('random/?$', 'index.php?random=1', 'top');
}
add_action('template_redirect','random_template');
function random_template() {
if (get_query_var('random') == 1) {
$posts = get_posts('post_type=post&orderby=rand&numberposts=1');
foreach($posts as $post) {
$link = get_permalink($post);
}
wp_redirect($link,307);
exit;
}
}
There’s plugins that do this sort of thing too, but this is such a simple little thing that it doesn’t really need a big amount of code to do.
Edit: Added get_permalink() optimization from @Raherian.
Comment Form Autocomplete Snippet
Google came out with an experimental specification for websites to provide “hints” on forms, to allow things like autocomplete to work better and be more standardized. Seems useful.
Here’s a quick plugin snippet you can use to make your comments form use this specification. Only Chrome 15 and up is using this at the moment, but in the long run I think most browsers will be implementing something similar to this, since filling out forms is just one of those endless pieces of drudgery that we could all stand to do away with.
Note that your theme will need to be using the comment_form() function call for this to work, otherwise you’ll just have to edit your comment form in the theme manually.
<?php /* Plugin Name: Add X-Autocomplete Fields to Comment Form */ add_filter('comment_form_default_fields','add_x_autocompletetype'); function add_x_autocompletetype($fields) { $fields['author'] = str_replace('<input', '<input x-autocompletetype="name-full"', $fields['author']); $fields['email'] = str_replace('<input', '<input x-autocompletetype="email"', $fields['email']); return $fields; }Simple little bit of code, really. Should work with any theme using the normal comment_form() function call.
