尝试将两个返回值添加到一个短代码PHP WordPress（帖子和页面的总数）

Question

I am new to php, please help. I am using this shortcode to show total number of published posts (400), it works fine. If I change ('post') to ('page') it shows total number of published pages (100) just as fine. I am trying to show total number of posts and pages (500) using one shortcode. Is it possible to add the two results and display as one total result?

function published_posts($atts) {
return wp_count_posts('post')->publish;
}
add_shortcode('posts_count', 'published_posts');

Yes, what you're attempting to do is possible. Simply assign the value of wp_count_posts() for both posts and pages to variables and then add them together in the return statement.

Example:

function published_posts( $atts ) {
    $post_count = wp_count_posts( 'post' )->publish;
    $page_count = wp_count_posts( 'page' )->publish;

    return $post_count + $page_count;
}
add_shortcode( 'posts_count', 'published_posts' );

While this will work, I'm not convinced it's the most efficient approach you could take. It's making two trips to the database for information which could be retrieved in one. That being said, wp_count_posts() won't accept an array of post types so you'd likely have to code something from scratch.
