WP REST Filter

Since WordPress 4.7 the filter argument for any post endpoint was removed.

This plugin restores the filter parameter for websites that were previously using it.

Usage

Use the filter parameter on any Post, or Custom Post Type endpoint such as /wp/v2/posts or /wp/v2/cpt as an array of WP_Query
argument. ACF values are also supported.

Default Post Type

fetch( 'https://domain.com/wp-json/wp/v2/posts?filter[meta_key]=acfkey&filter[meta_value]=acfvalue'); 

Filter Users

fetch( 'https://domain.com/wp-json/wp/v2/users?filter[meta_key]=acfkey&filter[meta_value]=acfvalue'); 

Custom Post Type

fetch( 'https://domain.com/wp-json/wp/v2/cars?filter[meta_key]=currency&filter[meta_value]=AUD'); // here 'cars' is the endpoint for CPT 

Advanced Custom Field

fetch( 'https://domain.com/wp-json/wp/v2/cars?filter[meta_key]=price&filter[meta_compare]=<&filter[meta_value]=200000'); // Query for car 'less' than '200000' in 'price' 

Advanced Custom Field – By Date (before, equal & after)

fetch( 'https://domain.com/wp-json/wp/v2/cars?filter[meta_key]=expiry_date&filter[meta_value]=2018-12-27T23:59:59&filter[meta_compare]=< // 'Expiry' Before '2018 Boxing Day ends' 

Advanced Custom Field – Value in Array (Single Value)

fetch( 'https://domain.com/wp-json/wp/v2/cars?filter[meta_key]=features&filter[meta_compare]=LIKE&filter[meta_value]=electric 

Advanced Custom Field – Search

fetch( 'https://domain.com/wp-json/wp/v2/cars?filter[meta_key]=brands&filter[meta_compare]=LIKE&filter[meta_value]=tesla
