smarty include file How to use variables_PHP tutorial

When I was using smarty to build a website today, there was a need to include file="dynamic path", which required using variables in the value of file. After trying for a long time, I finally solved it. I think the method is It's quite clever. I've never used smarty like this before, so I'll record it here.

Let’s talk about how to use variables in the value of include file!

include file={$path}"header.dwt" or include file="{$path}header.dwt"

The above two ways of writing are wrong. Using variables directly in the template does not work. We can write it in a php file. The final correct writing is as follows:

You can write this in the php file:

$header=$path.'header.dwt';
$smarty->assign('header',$header);

is written like this in the template file:

{include file=$header}
