\nOn va donc \u00e9crire un feed sur mesure car nous avons souvent des besoins sp\u00e9cifiques \u00e0 utiliser l’information d’un blog ou d’un site, fait sous WordPress, tout en ayant le minimum de langage \u00e0 disposition pour retravailler ce flux.<\/p>\n

Par d\u00e9faut WordPress g\u00e9n\u00e8re plusieurs formats de flux (RSS, RSS2, et Atom) et leur structure de permalien est d\u00e9finie dans l’objet $wp_rewrite<\/code> mais on se trouve souvent dans l’obligation de g\u00e9n\u00e9rer son propre feed que l’on pourra \u00e0 loisir rendre personnalisable.<\/p>\n

Notre plugin myfeed<\/code><\/h4>\n

Notre objectif est d’afficher les 5 derniers article d’une cat\u00e9gorie particuli\u00e8re, en l’occurrence la cat\u00e9gorie ayant un ID 24<\/code> \u00e0 cette adresse : http:\/\/mon-site-sous-wp\/feed\/myfeed\/<\/code> <\/b><\/p>\n

Voil\u00e0 le r\u00e9sultat de notre plugin, c’est assez simple et pour se faire on a copi\u00e9 le code disponible dans le fichier de base livr\u00e9e avec WP feed-rss2.php<\/code>.<\/p>\n

Une des choses les plus importantes est que lorsque vous avez activ\u00e9 le plugin, il ne faut pas oublier de bien g\u00e9n\u00e9rer \u00e0 nouveau les permaliens via l’outil administration de WordPress pour faire exister le feed \u00e0 l’adresse suivante http:\/\/mon-site-sous-wp\/feed\/myfeed\/<\/code> <\/b><\/p>\n
