I have created a custom payment gateway plugin for WooCommerce. The plugin activates without any errors, and debugging logs show that the gateway class is registered and initialized. However, the payment method does not appear in the WooCommerce checkout page, and the message “There are no payment methods available” is displayed.

Here’s the complete code for the plugin:

<?php
/**
 * Plugin name: Noob Payment for Woocommerce
 * Plugin URI: http://www.insafinhaam.com/custom-woocommerce-payment-gateway-plugin
 * Author: Insaf Inhaam
 * Author URI: https://insafinhaam.com/
 * Description: This Plugin allows for local content payment system
 * Version: 1.0.0
 * License: 0.1.0

            public function thank_you_page()
            {
                if ($this->instructions) {
                    echo wpautop($this->instructions);

}

add_filter('woocommerce_payment_gateways', 'add_to_woo_noob_payment_gateway');

function add_to_woo_noob_payment_gateway($gateways)
{
    $gateways[] = 'WC_Noob_pay_Gateway';
    return $gateways;
}

What I have tried:

• Confirmed that WooCommerce is active.

• Verified that the plugin activates without any errors.

• Checked the WordPress debug log, which shows that the WC_Simple_Noob_Pay_Gateway class is registered and initialized.

Expected Result:

The “Noob Payment” method should appear as a payment option on the WooCommerce checkout page.

Actual Result:

The checkout page displays the message: “There are no payment methods available. This may be an error on our side. Please contact us if you need any help placing your order.”

Any help in resolving this issue would be greatly appreciated. Thank you!
