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…
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…
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…

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…
