As stated in the documentation: (bold formatting was added by me) Note that meta_query expects nested arrays, even if you only have one query. So your meta query should actually look like the following, and note that in a meta_query, we don’t use the meta_ prefix, e.g. we use just key and not meta_key: $query_args[‘meta_query’] … Read more
Looking at the codebase, the only difference appears to be that category__not_in excludes child terms from selection, whereas cat does not. Should category__not_in be used with caution, similar to posts__not_in? Absolutely, but for different reasons. The main issue with excluding posts is that it causes problems for caching – every query with a different excluded … Read more
As far as I know, WordPress only stores original authors of the posts. If you want to also save the publisher’s ID, you need to do a bit of custom coding, or use some 3rd party plugin. Essentially what you need to do is to store the user ID whenever the post status is being … Read more
WP_Query doesn’t have a fallback system in it. It just executes the query with the given parameters. One option is just to check, if the first query has any posts and if not, then run another query with different parameters. Another way is to conditionally build up the parameters. So first get the tag term … Read more
Custom WP_query in Jnews theme returns thousands of posts
Plugins and themes are loaded pretty early in WordPress’s lifecycle. Assuming this code is a plugin file or a theme’s functions.php file, then it is executing before WordPress has set up the query, or even parsed the arguments in the request. The queried object ID is 0 because no query has taken place yet 🙂 … Read more
This just requires adding additional parameters to the query->set() array… …it’s standard WP_Query() stuff. So you’d essentially be taking this line: $query->set( ‘post_type’, [ ‘libri’, ‘post’] ); …and expanding it to include a tax query… $tax_query = array( ‘relation’ => ‘OR’, //can also use ‘AND’ depends how you want it to work array( ‘taxonomy’ => … Read more
Yes, using ‘posts_per_page’ => -1 is a bad practice as it loads every matching post from the database, which can mean hundreds, thousands or millions of entries in the worst case. And it looks like you only need post ID’s in your code, not the whole post objects. This means you can slim down the … Read more
It is not entirely clear what you are trying to do but sticky posts should be at the top– that is, the first posts displayed– already unless you have made an effort to prevent that. That is the default. I just tested this with your query, changing only the category ID to something that exists … Read more
As the error states, your $my variable is not defined. The reason behind it is that you only defines $my when $the_query->have_posts(). Adding $my = ‘No results found’; right after $the_query = new WP_Query( $args ); would solve your problem. $my would then be redefined if results are found.
