In some cases, you may want more than 100 results. In my case, I was building a web app using Angular and it needed to load all the customers on the page. Since there were only 150 or so customers and I knew that they would never cross 500 , I wanted to load all of them in one request and display later using data tables.
I could not find any resources that allowed me to override number of results. A bit of research lead me to rest_{$this->post_type}_query hook. It executes only for the post type we mention, so that’s perfect for our use case.
In my case, here’s the code I ended up with:
The post type in my case is customer. So the hook becomes rest_customer_query. $params is just an array passed to our function that’s used for WP_Query. You can modify it to alter results. I am setting $params['posts_per_page'] to PHP constant PHP_INT_MAX to get all the results.
Have any better approach in mind? Do let me know via comments.
