Copy the module into <thelia_root>/local/modules/ directory and be sure that the name of the module is SmartyRedirection.
Activate it in your thelia administration panel

Add it in your main thelia composer.json file

composer require thelia/smarty-redirection-module ~1.0.0

Usage

You can use the {redirect } function like {url }. Only one parameter is specific to this function: status.

If this parameter isn't given, its value is 302. Otherwise, you can set it to 301 to define a permanent redirection in a template.

Example

{if ! $foo}
    {redirect path="/anywhere"}
{/if}

{if ! $foo}
    {redirect path="/anywhere" status=301}
{/if}
