How WordPress transients work

Transients work by storing knowledge within the WordPress database utilizing a key-value pair construction. This secret’s used to establish the transient, whereas the worth specifies the information that’s being saved.

• $worth: that is the information that’s being retrieved by way of an API.
• $expiration: this specifies how lengthy the information can be saved within the database earlier than it’s deleted and wishes to be fetched by way of the API once more.

To set the transient, you’d want to use the set_transient() operate. So, right here’s what the ultimate outcome would appear to be:

set_transient( 'special_query_results', $special_query_results, 12 * HOUR_IN_SECONDS );
