Here is a quick and undocumented fix for placing postal code before city name in address fields generated by Gravity Forms plugin:
add_filter( 'gform_address_display_format', 'place_zip_before_city' );
function place_zip_before_city() {
return 'zip_before_city';
}
Knowing these keyboard shortcuts for working with terminal is an incredible time saver and basically a necessity for every web developer.

In this paper (.pdf) Ali Rantakari covers the complexities of parsing the Markdown markup language and building a Markdown syntax highlighter. A great read for anyone making any kind of syntax highlighter.
I just wrote a tutorial on how to use Git (and GitHub) with Subversion mirroring for WordPress plugin development
WordPress doesn’t fully support adding plugins by using symbolic links in the wp-content/plugins folder. This is because plugins_url() which is often used for enqueuing plugin CSS and Javascript files uses plugin_basename() which in turn relies on WP_PLUGIN_DIR constant for extracting the plugin’s basename. However, the path to a symlinked plugin doesn’t include WP_PLUGIN_DIR and therefore it fails at this replacement:
$file = preg_replace('#^' . preg_quote($plugin_dir, '#') . '/|^' . preg_quote($mu_plugin_dir, '#') . '/#','',$file); // get relative path from plugins dir
The solution is to use the following plugins_url filter:
// Allow symlinking this plugin
add_filter( 'plugins_url', 'your_plugin_symlink_fix', 10, 3 );
function your_plugin_symlink_fix( $url, $path, $plugin ) {
// Do it only for this plugin
if ( strstr( $plugin, basename(__FILE__) ) )
return str_replace( dirname(__FILE__), '/' . basename( dirname( $plugin ) ), $url );
return $url;
}
or replace all instances of plugins_url( '/js/plugin.js', __FILE__ ) with something like:
WP_PLUGIN_URL . '/' . basename( __DIR__ ) . '/js/plugin.js'
It appear as most stock-plugins are configured in
/etc/munin/plugin-conf.d/munin-node. This isn’t the case for the Memcached plugin. Hence this post.
An RSS feed with enclosure element linking to a thumbnail of featured image
Apparently WordPress doesn’t add featured images as proper enclosures to the RSS feeds, so I created a little plugin called Feed Image Enclosure that will do just that. You can download it from GitHub.
Add Custom Image Sizes to Media Uploader – It’s been long since I wanted to write a tutorial on doing just that. Thanks Pippin!
I recently updated my server to PHP 5.4 and discovered that I was no longer able to restart the PHP-FPM service using the regular:
$ /etc/init.d/php5-fpm restart
or
$ service php5-fpm restart
I went to the official Debian GIT repository for the PHP 5.4 beta package and found the following differences between the init scripts (here is the one from Dotdeb):
Replacing my init script with the one from the official beta package solved the problem. I wonder what export ZEND_DONT_UNLOAD_MODULES=1 does wrong.
Update: This is useful only if you can’t edit your local /etc/hosts file (using a tool like Gas Mask makes it fast and super easy) and use the production domain for development.
To my knowledge, there was no way to work on a WordPress Multisite network locally while using a production database, so I spent a few hours and created a simple MU plugin which allows you to do just that.
The way Multisite Local Dev works is it filters all get_option and get_site_option calls for siteurl and home values to correct the site URLs. In addition, we define both $current_site and $current_blog globals already in wp-config.php to stop WordPress from querying database for these variables in wp-includes/ms-settings.php, which is the key to this solution.
Currently this works only with sites in sub-folders, but it should be relatively easy to modify it for either subdomains or separate domains.
