Hi

I've a problem with a variable. My {$whatever} Smarty variable stores this value "$25.00" and i want to remove the $ symbol. Even if i can do it easly with {$whatever|substr:1}, this method doesn't work with symbol because it's a multibyte character.

I tried to remove the from "25.00" with {$whatever|mb_substr:1} and also with {$whatever|escape:'html':'UTF-8'|substr:1} with no success. How can i fix this issue with Smarty?

try:

Code:
{$whatever|regex_replace:"/[^0-9\.]+/",""}


ideally, you would assign the currency symbol and amount to smarty separately.

Thank you. I fixed your code (: instead of ,):
Code:
{$whatever|regex_replace:"/[^0-9\.]+/":""}


Anyway i know that i should make this kind of modifications on top directly with php but as i said above i'm working with obfuscated php files so i can only work on tpl with smarty.
