How to query custom fields via meta_query?

WordPress has vast functionality to customize and we can create custom post types and custom fields as many as we required. We can also make queries them to show search results. I got chance to make custom search feature for a wordpress project. That required custom post type and custom fields. For custom fields I used meta_query.

I have 4 custom fields to search in.

$args=array(
'post_type' => 'your-post-type', // any post type
'post_status' => 'publish',
'posts_per_page' => -1, // to show all posts on 1 page
'meta_query' => array(
'relation' => 'OR',
array('key' => 'Custom Field 1','compare' => 'LIKE','value' => $customfield1),
array('key' => 'Custom Field 2','compare' => 'LIKE','value' => $customfield2),
array('key' => 'Custom Field 3','compare' => 'LIKE','value' => $customfield3),
array('key' => 'Custom Field 4','compare' => 'LIKE','value' => $customfield4)
);
);
query_posts( $args );

After that make loop to show posts. That’s it hope it will be helpful. You can learn more on WordPress WP_Query
