Display different contents according to invoice payment status

[howardroark]

Hello,

 

I'm trying to modify the file complete.tpl so that:

_ If the invoice is paid, my custom "thank you message" will be shown (1).

_ If the invoice is not paid, another custom message instructing user to go to invoice page will be shown (2).

 

Here is my code:

 

----------------------------------------

<link rel="stylesheet" type="text/css" href="templates/orderforms/{$carttpl}/style.css" />

 

<!-- (1) If the order is fully paid -->

{if $ispaid}

<div id="order-boxes">

<p>My "thank you" message.</p>

</div>

 

<!-- (2) If the order is not fully paid -->

{else}

<div id="order-boxes">

<p>My instruction</p>

<p align="center"><a href="viewinvoice.php?id={$invoiceid}" target="_blank">{$LANG.gotoinvoice} {$invoiceid}</a></p>

</div>

 

{/if}

----------------------------------------------------

 

 

I have carefully reviewed and found no problem in this code. However, the code behaves very strangely:

_ Even if the invoice is paid (It's status in WHMCS --> Billing --> Invoices is "Paid"), (2) is ALWAYS shown FIRST when the browser returns to the Complete Page (cart.php?a=complete). (2) is shown even when I press F5 several times.

_ After (2) is shown, I open the invoice link (viewinvoice.php?id=xxxx), and is immediately redirected to the Complete Page again, this time (1) is shown!

_ From this point, pressing F5 on the Complete Page will always lead to (1).

 

Please help me solve this problem.
