Most downloaded WordPress plugins ever
Best Design Options has compiled a list of the 10 most downloaded WordPress plugins of all time. The data is readily available at the WordPress plugin repository, but this post prioritizes download history instead of rating, which the WP site does.
- All in One SEO Pack
- Akismet
- Google XML Sitemaps
- NextGEN Gallery
- Contact Form 7
- WordPress.com Stats
- WP Super Cache
- Sociable
- Google Analyticator
- Google Analytics for Wordpress
Three Google-related plugins, two of which are for the same purpose—site analytics, but both were beaten by WordPress.com’s own stats service and plugin. Contact Form 7 and NextGEN Gallery are the most popular contact form and gallery plugins, respectively.
Force WordPress theme CSS changes immediately
Theme authors: if you’ve been tweaking a WordPress site’s CSS file, the changes you’ve made usually don’t immediately show up for the blog visitors without a forced refresh. The reason: web browsers usually keep cached copies of site files. Mark Jaquith has a neat fix that allows you to grab the latest version of the CSS file and override the cached one automatically.
Just use this line of code in your header.php file:
<link rel="stylesheet" href="<?php bloginfo('template_url'); ?>/style.css?v=<?php echo filemtime(TEMPLATEPATH . '/style.css'); ?>" type="text/css" media="screen, projection" />This automatically updates the
?v=part every time you modify the file. Boom. Now everyone instantly sees your changes.
This should also work for other files like your Javascript files.
