This is the name of the directory where compiled templates are located. By default this is ./templates_c, meaning that Smarty will look for the templates_c/ directory in the same directory as the executing php script. This directory must be writeable by the web server, see install for more info.

Technical Note

This setting must be either a relative or absolute path. include_path is not used for writing files.

Technical Note

It is not recommended to put this directory under the web server document root.


As of Smarty 3.1 the attribute $compile_dir is no longer accessible directly. Use getCompileDir() and setCompileDir() instead.

See also getCompileDir(), setCompileDir(), $compile_id and $use_sub_dirs.
