如何获取自定义页面的RSS提要？

时间：2012-12-20 作者：bran

我的博客上有一个自定义页面，没有显示RSS feed. 您可以看到code here 用于自定义页面。我不确定我需要做什么来为该页面上的每个帖子制作rss提要。我自己不太懂php，所以非常感谢您的帮助。

您可以在wordpress中创建自己的提要。

将此添加到函数。php：

function my_customfeed() {
load_template( TEMPLATEPATH . \'your-customfeed.php\');
}
add_action(\'do_feed_customfeed\', \'my_customfeed\', 10, 1);

这将启用一个名为customfeed的新提要。

现在您可以创建自定义提要。新rss的主题目录中的php。为了简化操作，您可以从/wp includes/feed-rss2复制rss2 wordpress模板。php和适应自定义页面的代码。

然后您可以使用http://yoursite.com/?feed=customfeed.

customfeed可以是您喜欢的任何唯一名称，只需确保在所有这些位置都替换，包括操作名称do\\u feed\\u customfeed。

ANOTHER METHOD (doesn\'t need to add code in functions.php)

一种更简单的方法是为提要创建一个模板，如下所示：

<?php
/*
Template Name: My Custom Feed
*/

$posts = query_posts(array(\'post_type\' => \'project\', \'posts_per_page\' => get_wizy(\'portfolio_num_projects\')));

include(\'wp-includes/feed-rss2.php\');
?>

然后在wordpress中创建一个空白页面（它可以被命名为任何名称，比如我的自定义提要），并在侧栏中选择您创建的模板（它具有相同的名称，它是用模板名称写的：…）。

现在，当您转到刚刚创建的页面的url时，您就有了提要。

WordPress可以通过hook创建一个新的feed，但feed的内容和格式都在您的待办事项中。

请参见以下插件，为帖子类型的草稿创建提要post 在WordPress中，您可以在URL上找到此提要example.com/?feed=drafts 钥匙drafts 来自此插件中的initadd_feed( \'drafts\', array( $this, \'get_draft_feed\') );. 内容和xml标记来自方法get_draft_feed.
