Well you can try and run debug_backtrace(); on your function. For example: function wpse_82183_debug( $query ) { //your query goes here, this is just a basic one if ( $query->is_home() && $query->is_main_query() ) { $query->set( ‘posts_per_page’, 1 ); //magic happens here var_dump(debug_backtrace()); } } add_action( ‘pre_get_posts’, ‘wpse_82183_debug’ ); There are also a number of plugins … Read more

I’m not quite sure what do you mean by you have extended the visual composer, but I do have a couple of concerns here. SoC -> From your code I detect that you are using a shortcode, which should have its own separate class. You should not extend the class to the visual editor (at … Read more
Milo is right, you should be using pre_get_posts instead of calling a 2nd query on load. This will make paging much easier. Whatever the orderby session you’re using it should still be accessible in the hook. The code to do so is fairly straightforward too, it would look like this: /** * Modify the query … Read more
I ran into this today. It’s a bug. I filed a bug report here: https://core.trac.wordpress.org/ticket/46797 The problem is this line of code: $qv[‘name’] = trim( $qv[‘name’] ); Source: https://github.com/WordPress/wordpress-develop/blob/a0ca5afd8977b5a3857084d9cb1bd345166e2f21/src/wp-includes/class-wp-query.php#L764 A (malicious) user sends a request that looks like: GET /?q=user/password&name[#post_render][]=passthru&name[#type]=markup&name[#markup]=echo ‘Vuln!! patch it Now!’ > vuln.htm; echo ‘Vuln!!’> sites/default/files/vuln.php; echo ‘Vuln!!’> vuln.php; cd sites/default/files/; echo … Read more

So, the best option is to save meta data as key / value pair. Query Serialized array Although it’s not a good approach, … Read more
You should use posts_join and posts_where filters to modify JOIN and WHERE clauses. add_filter( ‘posts_join’ , ‘se333659_posts_join’, 20, 2 ); add_filter( ‘posts_where’ , ‘se333659_posts_where’, 20, 2 ); function se333659_posts_join( $join, $query ) { global $wpdb; if ( isset($query->query_vars[‘_rev_of_publ’]) && $query->query_vars[‘_rev_of_publ’] == ‘1’ ) { $join .= ” LEFT JOIN {$wpdb->posts} AS rev_p ON ({$wpdb->posts}.post_parent = … Read more
Update with a better example header( ‘Content-Type: text/plain;charset=utf-8’ ); error_reporting( E_ALL | E_STRICT ); function failed_unset() { // Copy the variable to the local namespace. global $foo; // Change the value. $foo = 2; // Remove the variable. unset ( $foo ); } function successful_unset() { // Remove the global variable unset ( $GLOBALS[‘foo’] ); … Read more
You should use add_feed() function (take name of feed and callback) to add new feed, it will take care of settings up hooks and rewrite rules automagically. Then in your callback function you can use query_posts() to override query before loading template.
