Buddypress插件bug-XML到PHP

它是一个外部组博客插件

它使BuddyPress上的组创建者和管理员能够将外部博客RSS源附加到组。 博客帖子将显示在组的活动流中。 如果有人专门访问某个组页面，则每小时或每30分钟自动删除一次新帖子

我发现了很多虫子。 1它不是自动获取提要的 2如果我试图手动更新feed，它会重新发布相同的条目，我的意思是它不会获取新的feed。 3 WordPress管理栏也不能正常使用此插件

此插件包含2个网页

首先，主页面是loader.php

<?php

/*
Plugin Name: External Group Blogs
Plugin URI: http://wordpress.org/extend/plugins/external-group-blogs/
Description: Allow group creators to supply external blog RSS feeds that will attach        future posts on blogs to a group.
*/

 /* Only load the plugin functions if BuddyPress is loaded and initialized. */
function bp_groupblogs_init() {
require( dirname( __FILE__ ) . '/bp-groups-externalblogs.php' );
}
add_action( 'bp_init', 'bp_groupblogs_init' );

/* On activation register the cron to refresh external blog posts. */
function bp_groupblogs_activate() {
wp_schedule_event( time(), 'hourly', 'bp_groupblogs_cron' );
}
register_activation_hook( __FILE__, 'bp_groupblogs_activate' );

/* On deacativation, clear the cron. */
function bp_groupblogs_deactivate() {
wp_clear_scheduled_hook( 'bp_groupblogs_cron' );

/* Remove all external blog activity */
if ( function_exists( 'bp_activity_delete' ) )
    bp_activity_delete( array( 'type' => 'exb' ) );
}
register_deactivation_hook( __FILE__, 'bp_groupblogs_deactivate' );

?>

第二个文件是bp-groups-externalblogs.php

我有一个停止活动流中重复数据的建议。可能每天使用一次wp cron api和当前日期xml提要获取系统。因此，它不会在组活动流中重复相同的提要。我们需要一个标准来停止bp组活动流中的数据重复。这是我项目的一部分。是否有其他方法可以获取提要并将其保存到组活动流中的mysql表中，然后将其显示为最新的组更新？

实际上它是自动获取的。 我在插件中看到了cron的用法。WordPress Cron仅在任何用户打开您的站点时触发。因此，没有用户，没有页面浏览，没有cron活动。在每个页面视图中，WP Cron都会检查启动任何函数的时间是否已到

---

也许会对您有所帮助-在单独的组选项卡中显示RSS提要。

我们在buddy media上也遇到类似问题。知道我们做了什么来修复它吗？我们停止使用buddy media。呵呵..但我需要这个插件。。BuddyPress上没有这个插件的替代品，您必须更具体地回答您的问题。如果有什么问题的话。。抱歉，这里不是其他程序员为你做这项工作的地方。我知道，但我只是想寻求一点帮助，…如果我要修复它，那么我将永远不会在这里发布它..我试图解决完全相同的问题。这就是我发现这个问题的原因。我不知道为什么它没有更新群订阅源。这是一个很好的插件，但有问题。我想在我的群活动流中rss订阅源更新，这样用户就可以在发布的订阅源上喜欢、评论或喜爱它。这是必要的。你能补充一下吗。。但无论如何，这是一个很好的脚本。你的插件并没有从rss保存数据，它只是实时获取提要并在组rss选项卡中显示它们。。分页也不起作用…看到这个没有分页，可能是因为rss提要中只有10个项目-没有更多显示。不保存-是的，这是最初的功能。无论如何，插件相当旧，甚至没有发布到WordPress插件库-因为它不完整。好吧。但它是一个好插件。我想你必须更新它，因为buddypress中没有可用的插件来显示来自外部源的rss提要。我已经检查了buddypress的hole插件目录。。所有这些都包含bug，它们已经过时了@斯拉夫
