This plugin adds Tax_Query support to the WP GraphQL Plugin for postObject query args (WP_Query).

Pre-req's

Using this plugin requires having the WPGraphQL plugin installed and activated. (version 0.0.15 or newer)

Activating / Using

Activate the plugin like you would any other WordPress plugin.

Once the plugin is active, the taxQuery argument will be available to any post object connectionQuery (posts, pages, custom post types, etc).

Example Query

Below is an example Query using the taxQuery input on a posts query. (Go ahead and check things out in GraphiQL)

This will find posts that are in the category "graphql" OR tagged with "wordpress".

query{
  posts(
    where: {
      taxQuery: {
        relation: OR,
        taxArray: [
          {
            terms: ["graphql"],
            taxonomy: CATEGORY,
            operator: IN,
            field: SLUG
          },
          {
            terms: ["wordpress"],
            taxonomy: TAG,
            operator: IN,
            field: SLUG
          }
        ]
      }
    }
  ){
    edges{
      cursor
      node{
        id
        postId
        link
        date
      }
    }
  }
}

The same query in PHP using WP_Query would look like:

$args = [
    'tax_query' => [
        'relation' => 'OR',
        [
            'terms' => ['graphql'],
            'taxonomy' => 'category',
            'operator' => 'IN',
            'field' => 'slug',
        ],
        [
            'terms' => ['wordpress'],
            'taxonomy' => 'post_tag',
            'operator' => 'IN',
            'field' => 'slug',
        ],
    ],
];

new WP_Query( $args );
