Woocommerce API连接到下订单按钮

Question

I am trying to connect to an api using the code below, so when the customer clicks on the "place order" button on the Woocommerce checkout page, I am getting a "please try again" error:

var amount = <?php global $woocommerce; print WC()->cart->total; ?>;
var merchantOrderId = '<?php echo print time(); ?>';
var apiKey = 'm85BXXLpf_icrSvqbElR11xquEgmKZ8wfeRb2ly3-G7pIwCKDuytgplB7AQGi-5t';

renderMMoneyPaymentButton(amount, merchantOrderId, apiKey);

I am trying to pass this information to the api via this function but I am not getting a successful connection.

public function process_payment( $order_id ) {

    global $woocommerce;

    // we need it to get any order detailes
    $order = new WC_Order($order_id);


    /*
     * Array with parameters for API interaction
     */
    $args = array(
     'amount' => '<?php global $woocommerce; print WC()->cart->total; ?>',
     'merchant_order_id' => '<?php print time(); ?>',
     'api_Key' => 'm85BXXLpf_icrSvqbElR11xquEgmKZ8wfeRb2ly3-G7pIwCKDuytgplB7AQGi-5t',
     'currency' => 'BBD',

    );
    /*
     * Your API interaction could be built with wp_remote_post()
     */
     $response = wp_remote_post( 'https://api.mmoneybb.com/merchant/js/mmoney-payment.js', $args );


     if( !is_wp_error( $response ) ) {

         $body = json_decode( $response['body'], true );

         // it could be different depending on your payment processor
         if ( $body ['$response'] == 'APPROVED') {

            // we received the payment
            $order->payment_complete();
            $order->reduce_order_stock();

            // some notes to customer (replace true with false to make it private)
            $order->add_order_note( 'Thanks for your payment!!!!', true );

            // Empty cart
            $woocommerce->cart->empty_cart();

            // Redirect to the thank you page
            return array(
                'result' => 'success',
                'redirect' => $this->get_return_url( $order )
            );

         } else {
            wc_add_notice(  'Please try again.', 'error' );
            return;
        }

    } else {
        wc_add_notice(  'Connection error.', 'error' );
        return;
    }

}

let me know what i am doing wrong much appreciated also this is the other script as well

 function renderMMoneyPaymentButton(amount, merchantOrderId, apiKey) {
  let paymentParams = {
    amount: amount,
    api_key: apiKey,
    currency: 'BBD',
    merchant_order_id: merchantOrderId,
    onCancel: function () { console.log('Modal closed'); },
    onError: function(error) { console.log('Error', error); },
    onPaid: function (invoice) { console.log('Payment complete', invoice); }
  };

  // "mMoney" window global provided by sourcing mmoney-payment.js script.
  // Attach the button to the empty element.
  mMoney.payment.button.render(paymentParams, '#mmoney-payment-button');


}

Answer 1

1) In your first snippet code you are using javascript and you need to get the order Id and then the order total… You can only get the Order ID after the order is placed…

There is an answer example here.

2) Your 2nd public function involves only PHP… There are some errors and mistakes in this code. Try the following revisited code instead:

public function process_payment( $order_id ) {

    // Get The WC_Order Object instance
    $order = wc_get_order( $order_id );

    /*
     * Array with parameters for API interaction
     */
    $args = array(
        'amount'            => $order->get_total(),
        'merchant_order_id' => $order_id,
        'api_Key'           => 'm85BXXLpf_icrSvqbElR11xquEgmKZ8wfeRb2ly3-G7pIwCKDuytgplB7AQGi-5t',
        'currency'          => $order->get_currency(),
    );

    /*
     * Your API interaction could be built with wp_remote_post()
     */
     $response = wp_remote_post( 'https://api.mmoneybb.com/merchant/js/mmoney-payment.js', $args );

     if( !is_wp_error( $response ) ) {

         $body = json_decode( $response['body'], true );

         // it could be different depending on your payment processor
         if ( $body ['$response'] == 'APPROVED') {

            // we received the payment
            $order->payment_complete();
            $order->reduce_order_stock();

            // some notes to customer (replace true with false to make it private)
            $order->add_order_note( 'Thanks for your payment!!!!', true );

            // Empty cart
            $woocommerce->cart->empty_cart();

            // Redirect to the thank you page
            return array(
                'result' => 'success',
                'redirect' => $this->get_return_url( $order )
            );

         } else {
            wc_add_notice(  'Please try again.', 'error' );
            return;
        }

    } else {
        wc_add_notice(  'Connection error.', 'error' );
        return;
    }

}

It should better work.
