8 # This file (along with its html template) demonstrates, documents and tests
11 # First we'll need the functions in wfpl/template.php:
12 require_once(__DIR__.'/../'.'template.php');
14 function tem_test_main() {
15 # Now grab the template (you might want to take a look at this file)
16 tem_load('tem_test.php.html');
17 # This creates a template object to store all sorts of things, and then reads
18 # in the template file and scans through it for sub-templates. Sub templates
19 # are parts of the template that may appear any number of times in the output
20 # (even zero times) such as a table row meant to hold a database record.
22 # This is probably not the best example, but this template contains tables for
23 # login, and for displaying some fake database content. For this silly example
24 # I decide which I'm going to display by checking if the user has submitted a
26 if(!isset($_REQUEST['user'])) {
27 # tem_set() gives a key/value pair to template.php. When the template is
28 # output (or sub-templates are run with tem_sub) any occurences of ~user~
29 # will be replaced with 'bert'.
30 tem_set('user', 'bert');
32 # The template file contains a sub-template called 'login'. By default,
33 # sub-templates do not display at all. They display once for each time you
37 # This runs the template and prints the output. Running the template is
38 # simply replacing all ~key~ tags with the associated value. The values are
39 # set with tem_set() and tem_sub().
45 # Below is an example of using a sub-sub-template many times
47 # first set some values to be displayed in the row:
48 tem_set('foo', '*&^@$<>"');
49 tem_set('bar', 'one*&^@$<>"');
51 # Now run the row. This runs the sub-template for the row, and appends the data
52 # for the 'foobar_row' entry in the main key/value list.
53 tem_sub('foobar_row');
55 # and a couple more times:
56 tem_set('foo', '"""""****"""""');
57 tem_set('bar', 'two*&^"');
58 tem_sub('foobar_row');
59 tem_set('foo', '<<<<<<&&&&&&&&>>>>>');
60 tem_set('bar', 'threeeeeeee*&^@$<>"eeeeeeeeeeee');
61 tem_sub('foobar_row');
63 # Now we have a 'foobar_row' in the main keyval array with three rows of html in it.
65 # in the template foobar_row is within a bigger sub-template called
66 # 'foobar_table'. The only reason for this is so that we can have that table
67 # not display at all when we're displaying the login. This is a silly use of
68 # the templates, but I wanted to demonstrate and test a simple use of a
69 # sub-template within a sub-template.
70 tem_sub('foobar_table');
73 # Now run the main template (the body of the template file)
77 # if this file were in a wfpl site proper, this would get called automatically,
78 # but this is here so you can run it directly from the examples dircectory:
