I found the solution. I was looking for: $wp_query->post_count And some of my assumptions were not correct. This is the actual output: Total posts from the loop 22. Posts per page 10. 1 sticky post. Page 1 gives 10 (9 + 1 sticky). Page 2 gives 10. Page 3 gives 2.
Did you actually find a case where there are any real comments in the wp-query object after running a normal query? If you examine the code in class-wp-query.php, you should find that the comments field only is populated with comments when a “comments-feed” is being queried for. In normal operation, comments are not retrieved by … Read more
User Rarst has a very famous answer where he lays out the load process. Looking at this graph whenever wp-blog-header.php gets loaded it calls function wp() which sets up many of WordPress globals like $post and $wp_query. ( Secondary Reference by User Gmazzap ) That’s the technical side of things but it looks like the … Read more
Stop WordPress to run main query is hard: you have to dig inside the deep heart of WordPress. WordPress frontend workflow: wp-blog-header.php call the function wp() wp() function creates an instance of wp class, and call main() method on it main() method code: public function main($query_args=””) { $this->init(); $this->parse_request($query_args); // build query vars starting from … Read more
EDIT 2 Here is another version of the code in EDIT 1. This code is about much more faster. Here is my test between the code in EDIT 1 and EDIT 2 EDIT 1 Database query time = +/- 0.25 and Database queries = 69 EDIT 2 Database query time = +/- 0.07 and Database … Read more
WordPress uses global $post variable. This way you don’t have to pass post nor post_ID as param for functions. So you can call the_title() and WP knows which title should it show. This behavior works fine, if there is only one loop on the site. But if you create your own custom loops and iterate … Read more
It’s actually a good question. Of course user input cannot be trusted, but also sanitizing the same value twice “just in case” isn’t the best solution for a problem. The only real answer to this question can be given by looking at the code and following what goes on. And after reading it for a … Read more
WordPress does its own query on every page. You should modify that query instead of creating a new one. What happens now is that WordPress does a query with the standard posts per page of 10, but you don’t do anything with these results and do your own query. This works… until WordPress goes beyond … Read more
I’m not sure you understand the logic of WP_Query. Rather than explain in words, here’s a code example; $query = new WP_Query( array( ‘meta_key’ => ‘Old ID’, ‘meta_value’ => $atts[‘oldid’] ) ); if ( $query->have_posts() ) return $query->posts[0]->post_title; return ”; Check out the codex on interacting with WP_Query. UPDATE: To use the query as you … Read more
