What’s new in the world of Polylang?

Polylang Pro 2.0 comes with major features for users having multiple domains: Another major improvement for Polylang Pro users is the integration of Advanced Custom Fields Pro: Custom fields are automatically copied when you create a new translation. Some new features are common to both versions of Polylang: Also some major changes, interesting mainly developers,…

I am glad to announce that the long awaited Polylang extension for WooCommerce is now available to allow you to create a multilingual shop. It is already tested by a few Polylang Pro customers for more than one month, some of them already using it on a production site. This extension can work either with Polylang…

Almost five years ago, I started writing a multilingual plugin for my personal needs. Three months later, I made it available to the public and released Polylang 0.1 on wordpress.org. To my great surprise, the number of users grew very rapidly. I started adding more features. Synchronization in 0.7, media in 0.9, WPML config file…

WordPress provides a lot of filters (and actions) to allow plugins or themes to modify the WordPress comportment. Among them, ‘get_search_form’ can be used to modify the search form. If a theme author codes a search form which does not pass through this filter, no plugin is aware of this search form and thus no plugin can…

Quite often, I see plugins calling WordPress functions before the action ‘plugins_loaded’ has been fired, i.e. before all plugins are loaded. Thus, plugins which are loaded after can’t make use of available filters. Among the most frequent functions called as soon as the plugin is loaded are the function ‘load_plugin_textdomain’ and the function ‘get_option’. For…

Quite often, i find in themes custom queries to customize the content displayed on a page. These themes use either ‘query_posts’ or ‘WP_Query’ to achieve that. For example, the code below allows to exclude posts of some categories from homepage. The author of this code took care to not override the query var ‘paged’, not to…

With the time, more and more plugins and themes intend to be multilingual compatible. As WPML is the most widely used plugin, they implement this multilingual compatibility on top of WPML. What’s fine is that Polylang mimics WPML by implementing the WPML documented API and the language configuration file wpml-config.xml. This is very interesting for…

Using the WordPress navigation menus is quite straightforward. First a theme location is registered. Here is an example taken from Twenty Twelve: Second, the navigation menu is displayed with ‘wp_nav_menu’. Here again is an example taken from Twenty Twelve: The function accepts quite a lot of (optional) arguments, but the most important one is ‘theme_location’….

A few Polylang users asked how to switch from WPML. That’s pretty easy to do manually but it is quite boring to do if there are tons of posts to migrate (you would have to set all languages and translations manually). Thus I wrote a small plugin which does automate the conversion. It imports languages,…

Yet Another Related Posts Plugin is probably the most popular related posts plugin for WordPress. And since Polylang 1.0, both plugins work together! Step 1: Go to YARPP settings page and in the “Relatedness” options metabox, choose ‘require at least one language in common’ for the Languages option. This will force YARPP to get related…

Some themes (Twenty Twelve, Responsive…) use the builtin WordPress custom header image. That’s a nice feature, but what if you include text in this header image? You will need one image per language! It is very easy to obtain thanks to the wpml-config.xml file. Step 1: create a directory ‘polylang’ in ‘wp-content’ (this is a…

For a very long time, Polylang allows to synchronize some post properties or metadata across translations. For example, you can synchronize taxonomies and custom fields. The site’s administrator decides this under Languages > Settings > Synchronizations. How does it work? Let say that you have a post about an event and that this post includes…
