WordPress 纯代码添加随便看看功能 进去随机一篇文章

WordPress 添加随便看看，也就是随机给出文章看看，点一下随机给你来一篇网站里面的文章看看，这个功能之前571分享家在wordpress增加一个点一下就能随机进入一篇文章的功能一文中使用PHP代码实现过一次，这次我们换个方式，直接使用wordpress的functions函数实现，更简单一点。

首先将如下代码加入到你网站主题functions.php文件中

// 添加随便看看
function random_postlite() {
global $wpdb;
$query = "SELECT ID FROM $wpdb->posts WHERE post_type = 'post' AND post_password = '' AND post_status = 'publish' ORDER BY RAND() LIMIT 1";
if ( isset( $_GET['random_cat_id'] ) ) {
$random_cat_id = (int) $_GET['random_cat_id'];
$query = "SELECT DISTINCT ID FROM $wpdb->posts AS p INNER JOIN $wpdb->term_relationships AS tr ON (p.ID = tr.object_id AND tr.term_taxonomy_id = $random_cat_id) INNER JOIN $wpdb->term_taxonomy AS tt ON(tr.term_taxonomy_id = tt.term_taxonomy_id AND taxonomy = 'category') WHERE post_type = 'post' AND post_password = '' AND post_status = 'publish' ORDER BY RAND() LIMIT 1";
}
if ( isset( $_GET['random_post_type'] ) ) {
$post_type = preg_replace( '|[^a-z]|i', '', $_GET['random_post_type'] );
$query = "SELECT ID FROM $wpdb->posts WHERE post_type = '$post_type' AND post_password = '' AND post_status = 'publish' ORDER BY RAND() LIMIT 1";
}
$random_id = $wpdb->get_var( $query );
wp_redirect( get_permalink( $random_id ) );
exit;
}
if ( isset( $_GET['random'] ) )
add_action( 'template_redirect', 'random_postlite' );

然后就可以了，使用的话，就是访问你网站域名?random 即可随机进入一篇文章。

这个URL无论放在哪里，只要有人点，就可以随机进入一篇文章，看个人需求，相放在哪里就放在哪里。
