Comment implémenter WP_List_Table? WP_List_Table Table to Listing List
J'essaie d'implémenter WP_List_Table pour mon plugin. J'ai parcouru ce tutoriel et utiliser son plugin sample .
J'ai installé ce plugin et viens de changer le nom de la table et légèrement modifié les fonctions suivantes:
nom_colonne, get_columns et get_sortable_columns
Maintenant, il montre la table mais au lieu de valeur, il montre un tableau de lignes. S'il vous plaît voir l'image:
Structure de la table:
CREATE TABLE IF NOT EXISTS `wp_fa_user_logins` (
`id` int(11) NOT NULL,
`user_id` int(11) DEFAULT NULL,
`time_login` datetime NOT NULL,
`time_logout` datetime NOT NULL,
`ip_address` varchar(20) COLLATE utf8mb4_unicode_ci NOT NULL,
`browser` varchar(100) COLLATE utf8mb4_unicode_ci NOT NULL,
`operating_system` varchar(100) COLLATE utf8mb4_unicode_ci NOT NULL,
`country_name` varchar(100) COLLATE utf8mb4_unicode_ci NOT NULL,
`country_code` varchar(20) COLLATE utf8mb4_unicode_ci NOT NULL,
`time_last_seen` datetime NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci AUTO_INCREMENT=4 ;

Puisque vous essayez seulement de rendreuser_id,browseretip_addresset que ceux-ci ne sont pas disponibles dans le cas du commutateur dont la valeur par défaut est default case et le cas par défaut imprime le entier tableau de l'item comme ceci (return print_r( $item, true );)
