Question

In smarty script I need to assign a random integer to a variable and display some content if that variable is odd or even. I know I can get a random integer with

{math equation = rand(1,20)}

But how to assign it to a variable and check if it is odd or even?

Answer 1

To assign to a variable in Smarty you can use

{$check=rand(1,20) nocache}

To check if a variable is even you can use

{if $check is even}
   ...
{/if}
