defince a variable ?

[rugg]

Hello,

 

on my invoice,

 

i need to get a value "{$invoice_total}+20",

 

by the way,

 

i need to define a variable like {$money55555555}={$invoice_total}+20,

 

can you please tell me how to do it ?

 

 

thank you

i would prefer the PHP variant:

 

old output: {$invoice_total}<br />

{php}
$itotal = $this->get_template_vars('invoice_total');
$itotal = $itotal + 20; // better (int)$itotal + 20;
$this->assign('awesomenewsmartyvar', $itotal);
{/php}

new output: {$awesomenewsmartyvar}

 

this should work as long as $invoice_total is a numeric string. if not try preg_match()

Hello,

 

should i put this code into which page to make it work ?

The code shows how you can change a SMARTY var technically.

 

Anyway manipulating an invoice sum is bungling!

For pre changing your invoice i recommend using the hook "UpdateInvoiceTotal" or "AfterShoppingCartCheckout.

 

For visible-only changes in cart and invoice you have to change the tpl viewcart.tpl and viewinvoice.tpl. But that is crap.

You can use smarty

{math equation="x + y" x=$invoice_total y=20 assign=money55555555}

then use that new variable like normal

{$money55555555}
