Email message rendered empty

[D9Hosting]

I'm pulling my hair out with some modifications I'm making to the "Invoice Created" email template.

 

I've added the following code to the template:

 

{if $invoice_payment_method eq "PayPal"}
<br /><br />If you have previously set up a PayPal billing agreement then*{$invoice_total} will be automatically taken from your PayPal account on or around the*{$invoice_date_due}. You can check the status of your billing agreements from within your*<a href="snip">Client Area</a>.*

{elseif*$invoice_payment_method eq "Credit/Debit Card"}
If you have a credit/debit card on file with us then*{$invoice_total} will be automatically taken from your PayPal account on or around the*{$invoice_date_due}.

{else}If you already have an active PayPal subscription set up to pay this invoice, payment will be sent to us by PayPal on or around the invoice due date and no action is required on your part.{/if}

 

But on attempting to send a test email it keeps coming back with:

 

Email Sending Failed - Email message rendered empty - please check the email message Smarty markup syntax

 

So there's obviously something wrong somewhere although it all looks fine to me.

 

If I remove the above code block from the email it works fine.

 

Help!

 

 

Edit: the * after the elseif statement has been added by the forum and isn't present in the actual code

[brian!]

have you pressed the HTML button in the email template page to view the source code - there may be some hidden code that is causing the issue.

 

also, have you checked the activity log as that might give you a clue.

Hi Brian,

Yeah, I've been doing all the editing via HTML view.

 

The logs are telling me the error is on line 85 due to an unclosed {if} tag, but from what I can see there are only 2 IF statements in there and both have been closed.

 

Entire code below:

As before, those *'s have been added by the forum and aren't present in the actual code.

[brian!]

those asterisks are bloody annoying when you're trying to debug code - never seen that here before.

 

if I remove the asterisks and use your code in my invoice created template, it works fine...

 

there's a redundant {else} (not the one in your new code) but apart from that, the only thing I can see that could cause an issue would be your use of strstr - if you haven't defined it in your Smarty security settings, then it will give an error... though not the one you describe.

 

https://docs.whmcs.com/Smarty_Security_Policy

 

other that that, and if you ignore the asterisks, I don't see any other obvious issues.

Well, as a last resort I copy/pasted the new bit of code into the template via the WYSIWYG editor rather than the code view and it worked. Don't you just love WHMCS! :evil:
