Raise the maximum number of cycles available in the recurring-expiration limit dropdown with a single filter.
When a coupon uses a recurring expiration, the Recurring Expiration Limit dropdown lets you choose how many cycles it runs before ending. By default the dropdown counts up to 20. Coupon Creator Pro builds that dropdown from a filterable amount.
Filter #
apply_filters( 'cctor_filter_recurring_limit_amount', 20 );
Return a larger number to extend the dropdown. This affects both the per-coupon field and the plugin option default.
add_filter( 'cctor_filter_recurring_limit_amount', function ( $amount ) {
return 30; // allow up to 30 recurring cycles
} );
Change 30 to whatever maximum you need. The dropdown then offers every value from 1 up to that number.
See Expiration & Recurring for how recurring expirations work and Pro Custom Fields for the cctor_recurring_expiration_limit meta key.
