Regarding Payment Gateway Redirect Methods

[knit-pay]

Hello Team

I understand, currently, there are 2 types of payment gateway redirect methods, METHOD_HTTP_REDIRECT and METHOD_HTML_FORM. In METHOD_HTTP_REDIRECT, the customer gets redirected to the action URL directly and in METHOD_HTML_FORM, a redirect page is visible to the customer (with Pay Now button) before he gets redirected to the payment gateway page.

I understand that in the METHOD_HTML_FORM redirection method, we can pass custom output fields on the payment redirect page using the get_output_fields function, which is getting displayed using the get_form_html function.

I want to know if there is a way to do METHOD_HTML_FORM redirection without showing the redirect page to the customer? For example on the WooCommerce checkout page, after selecting a payment method and clicking "Pay Now", the customer should directly redirect to the payment gateway page, instead of showing the redirection page. Can we show a hidden custom field on the WooCommerce checkout page, instead of a redirection page and redirect customers directly to the payment gateway page.
This particular thing will help me several ways. For example, there are certain payment gateways, in which both METHOD_HTTP_REDIRECT and METHOD_HTML_FORM don't work. In these payment gateways, they show the iFrame popup box directly on the checkout page instead of any kind of redirection. As a workaround, I am overriding the get_form_html function and doing all the javascript-related tasks on the redirection page, and showing the iFrame pop-up box on the redirection page. But if we will be able to load get_form_html on the checkout page instead of the redirection page, it will look good for particularly those payment gateways in which there is no redirection at all.

What do you suggest, is there any functionality already there to handle iframe related checkouts? Is there any better way to implement it? Can we do the enhancement and show the output from get_form_html function directly in extensions checkout instead of redirect page?

There is no specific functionality for this.

Depending on what this field should contain, you might be able to do something with get_input_fields() or print_fields() in https://github.com/wp-pay-extensions/woocommerce/blob/develop/src/Gateway.php#L1055-L1073
