-No PHP knowledge is required to manage smarty templates.
-Web designer and PHP developers can easily work and don't blame each other. ( When they develop a big websites )
Smarty offers tools
- granular data caching
- template inheritance
- functional sandboxing to name a few
How to install?
Unzip the downloaded smarty file into your appserv/www folder and run the application.
Basic syntax in the smarty
In the index.php file (In the root folder of your application )
a) Include the smarty class ( Which is libs folder).
require('libs/Smarty.class.php');
b) Create object to the that smarty class
$smarty = new Smarty;
c) Assign variables
$smarty->assign("var_name", "Smarty");
Here:
“var_name” is to use in the smarty template ( .tpl file)
“Smarty” is the value to that
Add Styles and Javascript files in templates files ( .tpl files)
Control Structure in smarty
Conditions
