PHP code doesn't get parsed in templates. The variables you see in templates, outside of the conditionals, hold values to be shown on screen. These variables need to be set before the call to the template if they are to show. Consider this example:

Code:

The PHP file:
<?php
// some vB prep here
$foobar = 5;
eval('print_output("' . fetch_template('barfoo') . '");');
?>

The template:
<!-- template barfoo -->
<html><body>
$foobar
</body></html>
<!-- /template barfoo -->

The output:
'5' is shown on screen

The <if condition=""> <else /> </if> template conditionals do allow a limited number of functions. The variables used in conditionals also need to be set before the call to the template if they are to be accurately evaluated. Consider this example:

Code:

The PHP file:
<?php
// some vB prep here
$foobar = 5;
eval('print_output("' . fetch_template('barfoo') . '");');
?>

The template:
<!-- template barfoo -->
<html><body>
<if condition="in_array($foobar, array(1,2,3,4,5))">
	$foobar is in the array
<else />
	$foobar is not in the array
</if>
</body></html>
<!-- /template barfoo -->

The output:
'5 is in the array' is shown on screen

The functions you can use in template conditionals are as follows:

Code:

PHP functions:
in_array, is_array, is_numeric, isset, empty,
defined, array

vBulletin functions:
can_moderate, can_moderate_calendar,
exec_switch_bg, is_browser, is_member_of

Plus you can add your own using the template_safe_functions hook.
