first,let me show you the files.

index.php
[php:1:1ec9644a21]
<?php
include_once ('Smarty/Smarty.class.php');
$smarty = new Smarty;
$smarty->compile_check = true;
$smarty->caching = true;
$smarty->display('head.tpl.html');
echo 'I am the content.'; //you can change this with the caching turned on
$smarty->display('foot.tpl.html');
?>
[/php:1:1ec9644a21]

head.tpl.html

if your biggest problem is, that insert has to *return* the output and not *echo* it: use output-buffering. ( http://php.net/manual/en/ref.outcontrol.php ) . it's damn easy and very powerful.

[php:1:9f1722c819]
function insert_foo($params, &$smarty) {
ob_start();
// output all stuff you want to be display not cached here
// do echo or print() or file() etc.. even include() or $smarty->display()
...
$ret = ob_get_contents();
ob_end_clean();
return $ret;
}[/php:1:9f1722c819]

well done,that's a good idea,I haven't thougt it before.
but I have heared somebody say that using the tag {insert} will be very slow,is that really?

BTW:
[php:1:ea24fc080b]<?php
function insert_foo($params, &$smarty) {
ob_start();
// output all stuff you want to be display not cached here
// do echo or print() or file() etc.. even include() or $smarty->display()
...
$ret = ob_get_contents();
ob_end_clean();
return $ret;
}
?>[/php:1:ea24fc080b]

Is this the way you solve the problem,I mean to keep some area varible when caching turned on.
