## Code

```php
$wpide_coupon_batch = array(
    'count'   => 25,        // Coupons to create (max 500 per run).
    'prefix'  => 'FLYER-',
    'type'    => 'percent', // percent, fixed_cart or fixed_product.
    'amount'  => 15,
    'expires' => '+90 days',
);

if ( ! class_exists( 'WC_Coupon' ) || ( ! current_user_can( 'manage_woocommerce' ) && ! ( defined( 'WP_CLI' ) && WP_CLI ) ) ) {
    return;
}

$wpide_codes = array();

for ( $i = 0; $i < min( 500, (int) $wpide_coupon_batch['count'] ); $i++ ) {
    do {
        $code = $wpide_coupon_batch['prefix'] . strtoupper( wp_generate_password( 8, false, false ) );
    } while ( wc_get_coupon_id_by_code( $code ) );

    $coupon = new WC_Coupon();
    $coupon->set_code( $code );
    $coupon->set_discount_type( $wpide_coupon_batch['type'] );
    $coupon->set_amount( $wpide_coupon_batch['amount'] );
    $coupon->set_usage_limit( 1 );
    $coupon->set_date_expires( strtotime( $wpide_coupon_batch['expires'] ) );
    $coupon->set_description( 'Generated batch ' . wp_date( 'Y-m-d' ) );
    $coupon->save();

    $wpide_codes[] = $code;
}

echo esc_html( implode( "\n", $wpide_codes ) );
```

## Notes

Runs only when you press Run in the editor or use WP-CLI, so set the amount, type and expiry first.
