Smarty将字符串连接到变量以获取另一个变量

Question

Hi I would like to concat a string into a variable to retrieve the value of another variable let say the example is below

# Variable one
filter_var = "The value to get"
name = "var"

# now I want to retrieve the value of filter_var. What I was thinking is something like this
{{ "filter_".name }} # assuming "name" variable has dynamic content

How do I solve this?

Edit:

Another sample is below

traduction.Product = "the value"
categorie = "Product"

# Now I'm trying to output the value in a div tag
<div>{{ traduction.{{categorie}} }}</div>

but I'm getting an error of Expected name or number.

Assuming you're using Smarty 3, you can use this:

{$filter_{$name}}

It's mentioned in the "Variable variables" section on this page: https://www.smarty.net/docs/en/language.syntax.variables.tpl
