How do I get a random post in Wordpress?
如何在 Wordpress 中获得随机帖子？
I would like to display a button on a page that, when pressed, goes to a random post from the blog. I don't want a random post to be displayed on the page, I just want a link that leads to that post. I tried searching for a code on Google and here at stackoverflow but no success.
我想在页面上显示一个按钮，当按下该按钮时，会转到博客中的随机帖子。我不想在页面上显示随机帖子，我只想要一个指向该帖子的链接。我尝试在 Google 和 stackoverflow 上搜索代码，但没有成功。
Thanks...

Here's a solution copy/pasted from the wpbeginner blog post. No copyright infringement intended.
这是从 wpbeginner 博客文章复制/粘贴的解决方案。无侵犯版权之意。
Just add the following code to the functions.phpfile:
只需将以下代码添加到functions.php文件中：
add_action('init','random_add_rewrite');
function random_add_rewrite() {
global $wp;
$wp->add_query_var('random');
add_rewrite_rule('random/?$', 'index.php?random=1', 'top');
}
add_action('template_redirect','random_template');
function random_template() {
if (get_query_var('random') == 1) {
$posts = get_posts('post_type=post&orderby=rand&numberposts=1');
foreach($posts as $post) {
$link = get_permalink($post);
}
wp_redirect($link,307);
exit;
}
}
Use mydomain.com/random/as your hreffor your button that leads to the random post.
使用mydomain.com/random/作为您href为您的按钮，导致随机职位。

create a page template, and use the following code to get a random post:
创建一个页面模板，并使用以下代码获取随机帖子：
//Create WordPress Query with 'orderby' set to 'rand' (Random)
$the_query = new WP_Query( array ( 'orderby' => 'rand', 'posts_per_page' => '1' ) );
// output the random post
while ( $the_query->have_posts() ) : $the_query->the_post();
echo '<li>';
the_title();
echo '</li>';
endwhile;
// Reset Post Data
wp_reset_postdata();
then in a page, just use:
然后在页面中，只需使用：
<a href="the link to the page">see a random post</a>

I find it is more useful to have a URL that will redirect to a random post that you can use as link in sidebar or in menus. If it is a single WP site and even on wp.com it's really easy, for a blog at
我发现有一个 URL 会重定向到一个随机帖子，您可以将其用作侧边栏或菜单中的链接，这会更有用。如果它是一个单一的 WP 站点，甚至在 wp.com 上，这真的很容易，对于博客
http://mygroovywpsite.me/
All you need to do is append it with ?random
你需要做的就是用 ?random 附加它
http://mygroovywpsite.me/?random
I found this did not work (nor the wp_beginner code above) on subsites in my multisite installation, either approach just loaded the home page. Maybe I had some funky cache issues. The way I do this on many sites is a few more steps w/o plugins.
我发现这在我的多站点安装中的子站点上不起作用（也不是上面的 wp_beginner 代码），这两种方法都只是加载了主页。也许我有一些时髦的缓存问题。我在许多网站上执行此操作的方式是多一些步骤，无需插件。
First make a Page in your site called "Random" / with the slug "random" -- it does not need any content in it
首先在您的站点中创建一个名为“Random”的页面/带有“random”的slug——它不需要任何内容
Then create a page-random.php template
然后创建一个 page-random.php 模板
<?php
/*
Random Post Picker
Use on page to send viewer to random post optionally mod query
*/
// set arguments for WP_Query on published posts to get 1 at random
$args = array(
'post_type' => 'post',
'post_status' => 'publish',
'posts_per_page' => 1,
'orderby' => 'rand'
);
// It's time! Go someplace random
$my_random_post = new WP_Query ( $args );
while ( $my_random_post->have_posts () ) {
$my_random_post->the_post ();
// redirect to the random post
wp_redirect ( get_permalink () );
exit;
}
?>
Then you get the re-direct for any link on your blog ...../random w/o any wrestling with .htaccess
然后，您将获得博客上任何链接的重定向...../random w/o 与 .htaccess 的任何角力
I've done it this way because I've had to modify the query, sometimes for custom post type, sometimes to restrict to category, etc.
我这样做是因为我不得不修改查询，有时是自定义帖子类型，有时是限制类别等。
I only had one site that was a problem because the hosting suppressed the use of mySQL queries with ORDER BY RAND()
我只有一个站点有问题，因为托管通过 ORDER BY RAND() 抑制了 mySQL 查询的使用
