Refrain from editing core files WordPress was developed with extensibility in mind, and provides many ways to change the appearance and functionality of an installation without altering the WordPress software itself (mostly using Hooks in conjunction with Plugins and Themes). The software is comprised of it’s “core files”, which are generally everything outside of the … Read more

Straight from the codex value (string|array) – Custom field value. It can be an array only when compare is ‘IN’, ‘NOT IN’, ‘BETWEEN’, or ‘NOT BETWEEN’. SOLUTION Change compare’ => ‘!=’ to compare’ => ‘NOT IN’
You don’t need the type variable and other bits of custom search query code, or custom functions like the other answers. In your searchbox, instead of submitting the form to / submit it to /my_post_type/ instead! WordPress will handle all the rest for you automagically, with no effort involved. What’s more this means all the … Read more
I tested the query and it does work so the only thing I can spot that is misleading but not right is directly after you while() statement you have the_post(). This doesn’t work in secondary queries, it should look like: <?php if( $subpages->have_posts() ) : ?> <?php while( $subpages->have_posts() ) : $subpages->the_post(); ?> … <?php … Read more

The big issue you have here is calling your post thumbnails. That adds about two queries per post, which is quite heavy. When we look at the source code of get_the_post_thumbnail(), we will see that the thumbnails is only cached on the main query, and not custom queries. So we would need to do that … Read more
Fields in database tables can not contain other types of data than text strings and numbers, and variations of them like dates and times. The field meta_value of wp_postmeta is a text field. So, when you store an array as meta_value you are really storing a string containing the serialized data that represents the original … Read more
You can’t do that. When you save postmeta (or any other meta, for that matter), WordPress runs it through maybe_serialize which turns objects and arrays into serialized data. When it gets pulled back out, it is run through maybe_unserialize. Serialized data looks something like this: a:1:{s:3:”one”;s:3:”two”;} In other words, what get’s stored cannot be queried … Read more
