After payment callback does not return to invoice automatically

[Shaz3e]

Hello,

I am developing a third party payment gateway where customer can pay through Mobile Account/Shop/CreditCard I am good till I submit the payment but when it returns to success/failure payment the callback shows blank page if I use 'header("Location: http://test.com/whmcs/viewinvoice.php?id=123");' the invoice gets updates but does not show information message i.e. Thank you! Up on successfull transaction and error message when the transaction is failed. What is a good practice to redirect from callback.php to invoice page without using an extra function? For reference integration guide and payment gateway is attached to this post.

Any help would be appreciated.

I understand that you need to display a success/failure message of payment when redirecting to view invoice page, correct me if I'm wrong.

you could use one of these URLs when redirecting your client to view invoice page:

http://test.com/whmcs/viewinvoice.php?id=123&paymentsuccess=true

http://test.com/whmcs/viewinvoice.php?id=123&paymentfailed=true

You are absolutely right, Thank you for your time for understanding my problem. What I want to know to redirect to the invoice page with prebuilt WHMCS function or should I use header() function for this purpose.

Now I want to know if there is any pre-built function in WHMCS so the user will be redirected to the invoice page and then shows a message.

the header("Location: URL-To-Invoice") is perfect

How about showing a message on invoice page? like, Thank you! or Decline Message

[sentq]

you can always edit the viewinvoice.tpl file, for example add the following:

{if $smarty.get.thankyou}<div class="alert alert-danger">Thank you!</div>{/if}

and redirect your client to this URL: http://whmcs/viewinvoice.php?id=123&thankyou=1

Thank you for your time answering my question. but I can see the code under viewinvoice.tpl how can I use default code instead of my own custom code.

{php}

            {if $paymentSuccessAwaitingNotification}
                {include file="$template/includes/panel.tpl" type="success" headerTitle=$LANG.success bodyContent=$LANG.invoicePaymentSuccessAwaitingNotify bodyTextCenter=true}
            {elseif $paymentSuccess}
                {include file="$template/includes/panel.tpl" type="success" headerTitle=$LANG.success bodyContent=$LANG.invoicepaymentsuccessconfirmation bodyTextCenter=true}
            {elseif $pendingReview}
                {include file="$template/includes/panel.tpl" type="info" headerTitle=$LANG.success bodyContent=$LANG.invoicepaymentpendingreview bodyTextCenter=true}
            {elseif $paymentFailed}
                {include file="$template/includes/panel.tpl" type="danger" headerTitle=$LANG.error bodyContent=$LANG.invoicepaymentfailedconfirmation bodyTextCenter=true}
            {elseif $offlineReview}
                {include file="$template/includes/panel.tpl" type="info" headerTitle=$LANG.success bodyContent=$LANG.invoiceofflinepaid bodyTextCenter=true}
            {/if}

{/php}

the following URLs will redirect you to view invoice and display the built-in message of success/failure payment:

http://test.com/whmcs/viewinvoice.php?id=123&paymentsuccess=true

http://test.com/whmcs/viewinvoice.php?id=123&paymentfailed=true

other options you see in tpl file doesn't work in the same way, but maybe you can try activating them using ActionHook:ClientAreaPageViewInvoice

<?php

add_hook('ClientAreaPageViewInvoice', 1, function($vars) {
    // Display Payment Pending Message if the "pendingreview" specified in the view invoice URL
	if (isset($_GET['pendingreview'])){
    	return array("pendingReview" => true);
    }
});

Thank you for helping me in this way.

Now I am getting success/failure message according to the parameters in the URL now I want to know I am using the following code to return on the invoice page I hope I am following the right direction.

<?php
if ( $success ) {
    addInvoicePayment(
        $invoiceId,
        $transactionId,
        $paymentAmount,
        $paymentFee,
        $gatewayModuleName
    );
?>
    <form method="GET" action="<?php echo $gatewayParams['systemurl'] . 'viewinvoice.php';?>" id="PaymentSuccessFul">
        <input type="hidden" name="id" value="<?php echo $invoiceId;?>">
        <input type="hidden" name="paymentsuccess" value="true">
    </form>
    <script>
        (function(){
            document.getElementById("PaymentSuccessFul").submit();
        })();
    </script>
<?php }else{ ?>
    <form method="GET" action="<?php echo $gatewayParams['systemurl'] . 'viewinvoice.php';?>" id="PaymentFailed">
        <input type="hidden" name="id" value="<?php echo $invoiceId;?>">
        <input type="hidden" name="paymentfailed" value="true">
    </form>
    <script>
        (function(){
            document.getElementById("PaymentFailed").submit();
        })();
    </script>
<?php } ?>
?>
