Inject external sponsor data into a credit at stamp time
Use benecaster_credit_before_stamp to pull the current sponsorship copy from an external source — a custom options page, a remote API, or a post meta field — and merge it into the stamped credit at the moment of application. Because stamping bakes the resolved text permanently into the episode, the sponsor copy is frozen to what was current when the episode was created, which is correct for pre-recorded sponsorships.
Code
<?php
/**
* Inject current sponsor promo code into the stamped credit.
* Template body must include {{PROMO_CODE}} as a replacement target.
* The filter fires BEFORE do_shortcode() runs, so any shortcodes in the
* injected copy are still resolved and frozen into _benecaster_stamped_credit.
*/
add_filter(
'benecaster_credit_before_stamp',
function ( string $body, int $episode_id, string $credit_id, \WP_Post $show ): string {
// Fetch the current sponsor data — stored in a custom options page.
