Shows how to add a custom order value to a connection to order by a custom field.

order-by-acf-like-count.php

add_filter( 'graphql_PostObjectsConnectionOrderbyEnum_values', function( $values ) {

	$values['LIKE_COUNT'] = [
		'value' => 'like_count',
		'description' => __( 'The number of likes on the post', 'wp-graphql' ),
	];

	return $values;

} );

add_filter( 'graphql_post_object_connection_query_args', function( $query_args, $source, $input ) {

	if ( isset( $input['where']['orderby'] ) && is_array( $input['where']['orderby'] ) ) {

		foreach( $input['where']['orderby'] as $orderby ) {

			if ( ! isset( $orderby['field'] ) || 'like_count' !== $orderby['field'] ) {
				continue;
			}

			$query_args['meta_type'] = 'NUMERIC';
			$query_args['meta_key'] = 'like_count';
			$query_args['orderby']['meta_value_num'] = $orderby['order'];

		}

	}

	return $query_args;

}, 10, 3);

@juanu96 I believe if the field is storing numbers, you need:

  $query_args['orderby'] = 'meta_value_num';

instead of:

$query_args['orderby'] = 'meta_value';

yes, this worked for me, thank you very much for your help

Hi all,

I've used this solution in my own code.

add_filter( 'graphql_PostObjectsConnectionOrderbyEnum_values', function( $values ) {

    $values['PARTNER_TIER'] = [
	    'value' => 'partner_tier',
	    'description' => __( 'Tier Level of the partner'),
    ];

    return $values;} 
);


add_filter( 'graphql_post_object_connection_query_args', function( $query_args, $source, $input ) {

    if ( isset( $input['where']['orderby'] ) && is_array( $input['where']['orderby'] ) ) {

	    foreach( $input['where']['orderby'] as $orderby ) {

		    if ( ! isset( $orderby['field'] ) || 'partner_tier' !== $orderby['field'] ) {
		    	continue;
		    }

		    $query_args['meta_type'] = 'NUMERIC';
		    $query_args['meta_key'] = 'partner_tier';
		    $query_args['orderby']['meta_value_num'] = $orderby['order'];

	    }

    }

    return $query_args;

}, 10, 3);

And while the initial call works, the cursor pagination is not working, and returning and empty set of partners when calling the next page.

Here's the working initial query.

And here's the query calling the next page

Was wondering if anyone else here had a similar issue or if there's something I am doing incorrectly

@ndigenpcc Did you ever find a solution to your problem? I'm facing something similar, and can't seem to find the bug.

@mickras I never ended up finding a solution, so I had moved back to the Wordpress REST API and created my own search filters

Thanks for posting this example, @jasonbahl ! It worked flawlessly for my use case (ordering posts by a Number ACF field VIEW_COUNT).
