# First we'll need the functions in wfpl/template.php:
require_once 'code/wfpl/template.php';
# Always use the exact require_once statement above to get access to these
# functions. You should have in each directory of your projects a copy of wfpl
# or a symbolic link to it. This allows there to be different versions of wfpl
# without changing the php for the site.
# Now grab the template (you might want to take a look at this file)
tem_load('tem_test.php.html');
# This creates a template object to store all sorts of things, and then reads
# in the template file and scans through it for sub-templates. Sub templates
# are parts of the template that may appear any number of times in the output
# (even zero times) such as a table row meant to hold a database record.
# This is probably not the best example, but this template contains tables for
# login, and for displaying some fake database content. For this silly example
# I decide which I'm going to display by checking if the user has submitted a
# username.
if (!isset($_REQUEST['user'])) {
# tem_set() gives a key/value pair to template.php. When the template is
# output (or sub-templates are run with tem_sub) any occurences of ~user~
# will be replaced with 'bert'.
tem_set('user', 'bert');
# The template file contains a sub-template called 'login'. By default,
# sub-templates do not display at all. They display once for each time you
# call tem_sub()
tem_sub('login');
# This runs the template and prints the output. Running the template is
