smarty3检测{include}是否包含模板

Question

In smarty3, is there a way to find out if a smarty template was included my the {include} tag? I know i just could do it that way for example:

{include file="blahblah.tpl" included=1}

And inside blahblah.tpl

{if $included==1}
  yadda yadda yadda 
{/if}

I just want to know if there's a simpler way.

Before including your template file , you can check with template_exists() , to see if template exists

if( !$smarty->template_exists($mid_template) ){
    $mid_template = 'page_not_found.tpl';
} else {
    $mid_template = 'blahblah.tpl';
}
$smarty->assign('content_template', $mid_template);
