Modules can provide a default output style and allow advanced theme builders to CLEANLY and EASILY modify their output.

Template Files vs Functions

Template Files (*.tpl.php) Functions

Output is printed<?php print $variable; ?>

Build a single output variable and return it.

$output .= “output”;

Easier to use if mixing a lot of plain html.

Easier to use if using control structures and loops.

The choice is up to you.

Template Files

In D 6.x you can create a template file for ANY theming hook.

Automatically recognized after theme cache is cleared.

Example...

*Note the underscore being changed into a hyphen.

Functions

Template.php is where the party is at!

Overridden functions are placed in template.php.

Keep this file organized with comments.

If it gets too big you CAN use php’s include function to include other files.

Example...
