How can i get my IPN works in woocommerce payment

Viewing 15 replies - 31 through 45 (of 55 total)

  • Hi guys,

    I too am having a problem.

    I have tried combinations of everything to try and get this to work but I am not having any luck.

    When I set up WC, I changed the Invoice Prefix to FF (instead of the default WC).

    So I tried this:

    global $woocommerce;

    $order = new FF_Order( $order_id );

    $order->payment_complete()

    Note: I changed the CC to FF

    This stsill didn’t work.

    I have turned on Auto Redirect in Paypal.

    I have tried this with both Redirect and Forced and I still don’t get a complete sale. It stays on pending.

    I also have the “grant access to download after payment” so that it should not rely on being complete.

    I also did as suggested and copied the templates folder into a woocommerce folder in my wordpress child theme. I have made changes to these documents only.

    I am new to WordPress and Woocommerce and am feeling a tad intimidated.

    Does anyone have a suggestion of what I have overlooked.

    Cheers Diamond

    Hi Diamond,

    WC_ is one of woocommerce function in their function files.
    Im not sure why you want to change to FF_ . If u change that , be sure in function files u have to change it too.

    But i would advice u to stick to woocommerce default.
    Have you check on your IPN log files in woocommerce? You can easily see it at plugin—> editor
    Then choose woocommerce then IPN log file.

    Good day!
    I’m a web developer based in Nigeria. I built woocommerce payent plugin based on Cashenvoy and Eyowo but the big issue is changing order status from pending to completed or processing on successful transaction. This has been a challenging issue and i hope someone get assist me in solving this. Thanks

    I looked at my file but do not understand where should I put this part: $ order-> payment_complete ()

    Help me, please.

    Hi anderson,

    Put it in your thankyou template that woocommerce generated.
    Try this:-
    <?php else : ?>
    <?php $order->payment_complete(); ?>
    <p><?php _e(‘Thank you. Your order has been received.’, ‘woocommerce’); ?></p>

    Hi winexviv, what was the issue u faced?

    The issue i’m facing is updating my order status from pending to completed or processing on successful payment. I’m suspecting that my gateway is not getting response. Here is my entire source code, please help me review

    [Excessive code outside of backticks moderated. Please post code or markup snippets between backticks or use the code button. Or better still – use a pastebin.]

    Quenielow, I dont find “thank you template”.

    just

    [woocommerce_thankyou]

    hi winexviv,

    you r not using paypal r u?
    could you see any log error when u make payment or when your payment being process?

    Hello Queenielow,
    I’m not using paypal. I’m using a payment gateway based in Nigeria https://www.cashenvoy.com . I’m not seeing any log error and I’m not receiving any response which should change my order status from pending to completed or processing.

    Hi Winexviv,

    After the payment, there’s no redirect back to Thank you page?
    if this gateway you purchase it from woocommerce, i suggest u ask them.

    if you created this plugin, you should maybe check with the bank that you are using.

    Here is the line of code that redirects to thank you page 'ce_notifyurl' => $redirect_url,. It recieves response with json decode. Please try and review the code.

    Hi I’m having problems with one of my WordPress E-commerce sites,

    The Template Design I’m using is called ‘Verde’, I think the last template update would have been in 2012 for this theme.

    I haven’t had any problems with customer orders until today. I can go through and select my products, I can add to cart, then when I select to go through to PayPal to make the payment, I receive this error message:
    (This is on the PayPal screen after being redirected)

    This invoice has already been paid. For more information, please contact the merchant.
    Your purchase couldn’t be completed
    There’s a problem with the merchant’s PayPal account. Please try again later.

    I had a similar problem on another website of mine, that also happened to have the same problem as this site but I simply updated the Woocommerce plugin which seemed to fix it.

    Having updated the Woocommerce plugin for this site however, I get this error message at the top of my dashboard in the back-end:

    Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘woocommerce_price_filter_init’ was given in /home/djukok/public_html/pueraria-mirifica.com/wp-includes/plugin.php on line 406

    The site still seems to work fine, however I still can’t get the paypal payment gateway to connect and function properly, where as the other site was a simple update to get it fixed.

    Can anyone please offer any advice or help in regards to this problem?

    Many thanks in advance,

    Sam
