Thanks for the suggestions, guys. I did some more research, and found this – https://wordpress.org/plugins/attachments/ It’s a great plugin that lets you attach images to the post without inserting them in the post and the images can be easily sorted with ajax, it’s also quite modifiable and just what I needed, and works on custom … Read more

You can use pre_get_posts action to exclude categories from search query. function wcs_exclude_category_search( $query ) { if ( is_admin() || ! $query->is_main_query() ) return; if ( $query->is_search ) { $query->set( ‘cat’, ‘-22, -21’ ); } } add_action( ‘pre_get_posts’, ‘wcs_exclude_category_search’, 1 ); You should paste this code in your theme’s functions.php file.
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

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
I recently needed the same thing, I had menu of categories and I needed to get the categories that in the menu. After a several hours digging in the WP core, I found the wp_get_nav_menu_items() function that helped me. I finnally came with this, 220 was my menu_id $navcat = wp_get_nav_menu_items(‘220’); foreach ($navcat as $obj) … Read more
You can set the taxonomy query for the main query using pre_get_posts: add_action( ‘pre_get_posts’, ‘my_exclude_terms_from_query’ ); function my_exclude_terms_from_query( $query ) { if ( $query->is_main_query() /* && whatever else */ ) { $tax_query = array ( array( ‘taxonomy’ => ‘category’, ‘terms’ => array( ‘cat-slug’ ), ‘field’ => ‘slug’, ‘operator’ => ‘NOT IN’, ) ); $query->set( ‘tax_query’, … Read more
It seems that is was a simple problem. get_posts() has various default settings, one of which is that the post_status is set to public and my custom post type which doesn’t use post_status used the default value, draft. To fix this you can either query by post status (see the code below) or change the … Read more
