Page output
Tpl::output (' index_sign ', ' brand ');
Model (' seo ')->type (' brand ')->show ();
echo "/////////";
$tl =tpl::showpage (' brand ');
Var_dump ($TL);
echo "";
The red code above is my attempt to print out the path of the template, but the result is not out, I do not know why. Of course, I also know that the method must have a problem, do not know where the problem is, the right way is what

How do you know that Tpl::showpage (' brand ') has a return value? Have you read the ShowPage or the source code?
