Developer's Guide

$mymodule = new MyModule();
$message = $mymodule->l( 'Welcome to my shop!' );
$smarty->assign( 'messageSmarty', $message ); // creation of our variable
$smarty->display( dirname(__FILE__) . '/mymodule_page.tpl' );
include( '../../footer.php' );
?>
From there on, we can ask Smarty to display the content of this variable
in our TPL file.
mymodule_page.tpl
{$messageSmarty}
PrestaShop includes a number of variables. For instance,
{$HOOK_LEFT_COLUMN} will be replaced with the content for the left
column, meaning the content from all the modules that have been
attached to the left column's hook.
All Smarty variables are global. You should therefore pay attention not to
name your own variable with the name of an existing Smarty variable, in
order to avoid overwriting it. It is good practice to avoid overly simple
names, such as products, and to prefix it with your module's name, or
even your own name, such as: {$mark_mymodule_product}.
