{if},{elseif},{else}{if} statements in Smarty have much the same flexibility as PHP
if
statements, with a few added features for the template engine.
Every {if} must be paired with an
{/if}. {else} and
{elseif} are also permitted. All PHP conditionals
and functions
are recognized, such as ||, or,
&&, and,
is_array(), etc.
If $security is enabled
then IF_FUNCS array in the $security_settings array.
The following is a list of recognized qualifiers, which must be
separated from surrounding elements by spaces. Note that items listed
in [brackets] are optional. PHP equivalents are shown where applicable.
