Extending BuddyPress Componenti (plugins) bp-custom.php (snippets) Temi

Plugin per BuddyPress • sono plugin per WP ma usano le API di BP (funzioni, azioni, ﬁltri) • eseguire il codice di BP solo dopo che viene caricato:/* Only load code that needs BuddyPress to run once BP isloaded and initialized. */function my_plugin_init(){ require( dirname( __FILE__ ) . /my-plugin.php );}add_action( bp_include, my_plugin_init );

Componenti example.org/groups/my-group/forum/topic/test-topic/current_component action_variables current_item current_action example.org/members/francesco/messages/1/view Accessibili tramite la variabile globale $bp http://codex.buddypress.org/developer-docs/the-bp-global/

Struttura dei componenti • Struttura standard • Usata anche per le funzionalità base di BuddyPress

BP Skeleton Component • Esempio di componente “high ﬁve” • Buona base di partenza per componenti personalizzatihttp://wordpress.org/extend/plugins/buddypress-skeleton-component/

bp-custom.php• wp-content/plugins/bp-custom.php• snippets di codice, piccole modiﬁche• cambiare slug ai forum: define(BP_FORUMS_SLUG, board);• rimuovere i link cliccabili dal proﬁlo: function remove_xprofile_links() { remove_filter(bp_get_the_profile_field_value, xprofile_filter_link_profile_data, 50, ); } add_action(plugins_loaded, remove_xprofile_links);
