WooCommerce plugin to set which payment gateway will be selected when the customer reaches the checkout.
Add ?payment_gateway=<gateway_id> to the URL you send your customer and when they reach the checkout, that gateway will be selected. e.g. https://store.brianhenry.ie/?payment_gateway=bitcoin
Useful for running promotions specific to a payment type, e.g. a Bitcoin related promotion, and useful for sending failed payment emails to customers with links to the checkout to place the same order again using a specified gateway.
This plugin makes no theme/user-facing changes.
Install Set Gateway by URL from the WordPress plugin directory.
There is no configuration needed.
Cart links for WooCommerce by Soft79 plugin adds similar functionality to WooCommerce allowing adding products to customers' carts via the URL, ?fill_cart=12,2x44.
WooCommerce Extended Coupon Features also by Soft79 enables applying coupons via URL, ?apply_coupon=my_coupon.
Autologin URLs, written by me, adds single-use login codes to URLs so customers can be logged in when they follow a link to your site.
Together, it is possible to send your customers URLs to your store's checkout which fill your customers' carts, apply a coupon, specify the payment gateway and as returning customers, have their billing and shipping information pre-filled!
The general form is to add ?payment_gateway=<gateway_id> to the URL querystring.
Gateways' ids do not necessarily match their titles, so this plugin adds a field on each gateway's settings page displaying a URL that can be copied and sent to customers.
If the gateway id is opaque or obtusely long, the filter set_payment_gateway_from_url exists so the text in the URL can be arbitrary.
/**
* When ?payment_gateway=abbreviation is set, use the areallylonggatewayidthatyoudontwantinyoururl gateway.
*
* @hooked set_payment_gateway_from_url
*
* @see BH_WC_Set_Gateway_By_URL\woocommerce\WooCommerce_Init::set_payment_gateway_from_url()
*
* @param string $gateway_id The gateway id used in the URL.
* @return string The gatway id as understood by WooCommerce.
*/
function translate_set_payment_gateway_id( $payment_gateway ) {
if( 'abbreviation' === $payment_gateway ) {
$payment_gateway = 'areallylonggatewayidthatyoudontwantinyoururl';
}
return $payment_gateway;
}
The plugin is hooked on woocommerce_init and exits quickly if the payment_gateway querystring is not set.
If the specified gateway does not exist, the plugin exits silently.
No data is saved by the plugin.
As I sought the solution for this myself, I found no plugin for it but did find a StackOverflow post WooCommerce : Pre Setting Default Payment Method on Cart Page which seems to get viewed ~50 times/month.
See github.com/BrianHenryIE/WordPress-Plugin-Boilerplate for initial setup rationale.
I credit the spare time I had to publish this to COVID-19. Stay safe.
