Cet article est destiné aux personnes ayant quelques connaissances en php et en WP (thème, modèle, …).
La fonction twentythirteen_xilidev_setup actionnée par le filtre “after_setup_theme” après (11) celui du parent va permettre de mettre en place les bons fichiers, instancier la classe “xili_language_theme_options” avec des paramètres personnalisés (nom du thème parent, nom du domaine pour la traduction,…) et rendre compte d’éventuelles erreurs. La classe “xili_language_theme_options_admin” n’est activée que du côté admin.

Le message en couleur jaune indique que tout va bien, les messages en rouge indique que l’extension xili-language n’est pas activée ou que sa version est ancienne. Idem si la classe n’est pas présente.
La function ‘special_head’ actionnée par le filtre ‘wp_head’ va agir sur la circonstance où l’on décide d’avoir un formulaire de recherche enrichi des langues disponibles pour cibler cette recherche. Une autre tâche est – selon les préférences – d’injecter dans une balise style les lignes css dans le header pour avoir le nom des langues remplacé par une image (drapeau).

La version xili-language propose le filtre ‘xl_propagate_post_attributes’. Donc selon le thème et la politique éditoriale, il est possible de choisir ce qui est copié lors de la création d’un article dans une autre langue. Le travail de l’auteur/traducteur est ainsi facilité : ici le post_format est recopié, idem pour le template en cas de page. Il est tout à fait possible d’imaginer que le format (ou le template ) ne soit pas le même selon chaque langue… c’est l’avantage de pourvoir coder.
