Custom queries in wordpress

We can create custom queries to show post for wordpress based websites or blogs. Custom query parameters can pass to wordpress function WP_Query. These queries cover posts, pages, taxonomies, custom fields. Following is the query for custom taxonomy with meta query.

        $args = array( 'post_type'=>'posttype',
           'post_status' => 'publish',
           'meta_query' => array(
                 array('key' => 'custom_key',
                 'compare' => '==',
                 'value' => 'any_value')
           ),
           'tax_query' => array(
              array(
                'taxonomy' => 'custom_taxonoy',
                'field' => 'field_to_compare',
                'terms' => 'field_value',
                'operator' => 'NOT IN'
               ),
            )
          );
$custom_query =  new WP_Query($args);

In above code example “posttype” is post type, in meta_query array “custom_key” is custom field name, “any_value” is custom field value, in tax_query “custom_taxonomy” is custom taxonomy name, “field_to_compare” is field name like “slug, id”, “field_value” is the value of field that is in “field_to_compare”.

For taxonomy query and meta query we must have to create array of array.

This is just one example and I used same way of custom query for one of my project. We can play with it in different ways to get our required posts.

Hope this will helpful. Thanks.
