I have pricing that I load from my billing system whmcs to my WordPress website using PHP.

I wanted to know if there is a way I can preload it for it to load nicely or cache only that page or something that will make the page just show without loading slowly.


  • How often is the pricing updated in your billing system? – ChristopherJones Jun 10 '19 at 21:29
  • @ChristopherJones Pricing is changed often. It links to the exchange rate. – Thovhakale Murendeni Jun 12 '19 at 10:50

WordPress has Transient and Object Cache APIs available. In a default WordPress install, Transients are stored in the database while Object Cache is stored in memory for the duration of the request. You can change this configuration to using something like Redis, Memcache, or APC to store and access this faster.

In your case, you'd want to use Transients.

Here's a good example from the Transient API Codex:

// Get any existing copy of our transient data
if ( false === ( $special_query_results = get_transient( 'special_query_results' ) ) ) {
    // It wasn't there, so regenerate the data and save the transient
     $special_query_results = new WP_Query( 'cat=5&order=random&tag=tech&post_meta_key=thumbnail' );
     set_transient( 'special_query_results', $special_query_results, 12 * HOUR_IN_SECONDS );

// Use the data like you would have normally...

  • Hi MikeNGarrett, Thanks for your solution. I will try and give you feedback. – Thovhakale Murendeni Jun 12 '19 at 10:51
  • My brain leans towards setting up a cronjob to hit a simple script that will get your pricing, and then pair it with @MikeNGarrett's idea of storing it with the Transient API. I like the idea of a cron so that you are not forcing the user's page load to go get your pricing data. All that is done behind the scene. So on page load, you are just running get_transient() – ChristopherJones Jun 12 '19 at 15:53
  • That's fine, but transients can be cleared or lost. Make sure you handle this scenario. – MikeNGarrett Jun 12 '19 at 17:05
