Smarty caching (with dynamic content)

I have a very dynamic (social network) site running smarty, for which I want to enable caching.

My structure: index.php display () s template.tpl template.tpl include () s indexContent.tpl

Most of the content in template.tpl is static, such as scripts, banner, footer, etc. How can I cache these, but not specific parts, that look different depending on whose input (among other factors)

I discovered 3 methods:

  • {nocache} {include='indexContent.tpl'} {nocache}
  • {dynamic} {include ...
  • Set cache_id for each page.

Unfortunately, each of them has a problem:

  • Really not working? Dynamic content is still cached.
  • Not sure how to implement or how it differs from (1)
  • ? "", ... , "myProfile.php"

? !!

{include file='head.html' cache_lifetime=5000}

or vice versa, delete the dynamic part of your page and put it in another template and include it as

{include file='head.html' nocache}

3. How to uniquely identify? Some pages have the same "name" but different content for certain members ... think "myProfile.php"

for the same page with different content, such as a profile page, you can pass the profile identifier as a parameter to cache the call.

$my_cache_id = $_GET['profile_id'];    
$smarty->display('index.tpl', $my_cache_id);

This ensures that the same page with different parameters will not be considered the same page.

Hope this helps.
