Here is a simple snippet of PHP and Javascript that checks if the input fields have been filled and submits the login form one second after the page has been loaded. All you have to do is append #quicklogin to your login bookmark URL so that it looks like http://example.com/wp-admin/#quicklogin and Javascript will do its magic. Add this to your functions.php.

add_action('login_footer', 'enable_admin_quick_login');
function enable_admin_quick_login() {
?>
	<script type="text/javascript">
		$url_hash = window.location.hash;
		if ($url_hash.indexOf('quicklogin') != -1) {
			setTimeout(function() {
				if (document.loginform.user_login.value && document.loginform.user_pass.value) {
					document.loginform.submit();
				}
			}, 1000);
		}
	</script>
<?php

A “widow” in typography is defined as:

A paragraph-ending line that falls at the beginning of the following page/column, thus separated from the rest of the text.

If you are using the standard inline “Read more” links at the end of post excerpts on index and archive pages, here is a simple filter to ensure that a non-breaking space is added before the “Read more” link:

add_filter('the_content_more_link', 'prepend_non_breaking');
function prepend_non_breaking($more_link) {
	return str_replace(' <a ', '&nbsp;<a ', $more_link);
}

Update: turns out that in WordPress 3.4 there are new default redirects (/admin, /dashboard and /login) implemented in the core (see this ticket). So here is a better way to add your own redirects which will work only if you don’t have a page or post with the same name (slug) already:

Updated Version:

add_action('template_redirect', 'add_my_custom_redirects');
function add_my_custom_redirects() {
	if (!is_404())
		return;
	$current_uri = untrailingslashit($_SERVER['REQUEST_URI']);
	$my_admin_uris = array(
		home_url('dash', 'relative'),
		home_url('your-custom-uri', 'relative')
	);
	if (in_array($current_uri, $my_admin_uris)) {
 		wp_redirect(admin_url());
 		exit;
	}
}

The Obsolete Version:

add_filter('generate_rewrite_rules', 'add_my_custom_rewrites');
function add_my_custom_rewrites($wp_rewrite) {
    $my_rewrites = array(
	'dash' => 'wp-admin'
    );
    $wp_rewrite->rules = $my_rewrites + $wp_rewrite->rules;
}

A standard tweet containing a prefix (such as “New blog post:”), post title and a link to that post is generated automatically by the plugin. Wouldn’t it be nice to include also post categories and tags as hashtags in order to add additional metadata along with the post title? Like so:

Post categories and tags replaced or added to tweet as hashtags

Thanks to the stc_publish_text filter supplied with the plugin there is an easy way to do it. Add this snippet to your theme’s functions.php:

add_filter('stc_publish_text', 'add_taxonomies_to_tweets', 10, 2);
function add_taxonomies_to_tweets($output, $id) {
	if ($cats = get_the_category($id))
		foreach ($cats as $c => $cat)
			$output = add_taxonomy_hashtag($output, $cat->cat_name);
	if ($tags = get_the_tags($id))
		foreach ($tags as $t => $tag)
			$output = add_taxonomy_hashtag($output, $tag->name);
	return $output;
}
function add_taxonomy_hashtag($tweet, $tax) {
	if (stripos($tax, ' ')) // Remove whitespace
		$tax = str_replace(' ', '', $tax);
	if (strlen($tweet) + 1 > 140) { // Check if the new tweet is not too long
		return $tweet;
	} elseif (stripos($tweet, $tax)) {  // Replace an existing word with a tag
		return str_replace($tax, '#' . $tax, $tweet);
	} elseif (strlen($tweet) + strlen($tax) + 1 < 140) { // or simply append it
		return $tweet . ' #' . $tax;
	}
	return $tweet;
}

I know that the latest WordPress update (version 3.3) broke both Widget Context and Tabbed Widgets plugins. I’ll be able to fix them only by the end of January 2012. Please check the WordPress forum for temporary fixes.

On putukrejums.lv blog we use the ‘sticky’ posts to add introductory information to all category pages (see here, for example). This approach is better than using the category description field because it allows for all the usual formatting options.

Here is how to add sticky posts on top of their respective category index pages and hide them from the rest of pages and indexes:

add_action('pre_get_posts', 'alter_stickies');
function alter_stickies($query) {
	if (!$query->is_category && !$query->is_single)
		$query->set('post__not_in', get_option('sticky_posts'));
}
add_filter('posts_orderby', 'sticky_orderby');
function sticky_orderby($orderby){
	global $wpdb;
	if (is_category())
		$orderby = "Field(". $wpdb->prefix ."posts.ID," . implode(',', get_option('sticky_posts')) . ") DESC, " . $orderby;
 	return $orderby;
}

Add the is-sticky class to the post wrap for additional formatting control:

add_filter('post_class', 'add_stickies_class');
function add_stickies_class($classes) {
	if (is_sticky())
		$classes[] = 'is-sticky';
	return $classes;
}

Redirect Sticky Posts to Their Category Index Page

We don’t want the sticky posts to be available as individual posts that can be access via their permalinks because this information is already being displayed at the top of every category index page. Here is a simple filter to redirect all sticky posts to their category index pages:

add_action('template_redirect', 'redirect_stickies');
function redirect_stickies() {
	global $wp_query;
	if (!is_single())
		return;
	$stickies = get_option('sticky_posts');
	if (empty($stickies))
		return;
 	if (in_array($wp_query->post->ID, $stickies))
		if ($cats = get_the_category($wp_query->post->ID))
			if ($cat = end($cats))
				wp_redirect(get_category_link($cat->cat_ID), '302');
}
