How to add new merge field for {$invoice_url} to emails

[Benbodhi]

Anybody know how I can create a new merge tag {$invoice_url} to be used in invoice email templates that returns just the URL of the invoice in question so I can use the plain text URL in a custom button?

 

I'm currently modifying all of my email templates.

When using the{$invoice_link} merge field, it outputs the entire link, when I only need the plain text url to use in a custom button's markup.

 

I have looked at adding hooks, but the only documentation I can find will replace existing content with custom content... Which could work, but I can't find anywhere in the codebase where the original {$invoice_link} is created to see how it pulls the URL in to that link.

 

Cheers

create new .php file inside /includes/hooks/ directory, and put the following code inside it

 

<?php

add_hook("EmailPreSend", 1, function($vars){

   global $CONFIG;

   return array("invoice_url" => $CONFIG['SystemURL']."/viewinvoice.php?id".$vars['relid']);

});

 

now in your email templates (Invoice Messages) use the {$invoice_url} to insert URL of invoice

if you're editing the templates in the way you describe, then you shouldn't really need a hook if the URL you want already occurs in an existing variable.

so in your email template, you have {$invoice_link} which, let's say, outputs the following code...

 

<a href="http://demo.whmcs.com/viewinvoice.php?id=1">http://demo.whmcs.com/viewinvoice.php?id=1</a>

you could use some Smarty code to obtain just the URL.

 

{$invoice_link|strip_tags:false}

... and you can then go on to use that in your button code, e.g...

 

<input onclick="window.location.href='{$invoice_link|strip_tags:false}'" type="button" value="Invoice Link" />

you should then find that you can add working links to your buttons - however, you decide to show them, e.g input forms, css etc.
