Control Structures
Smarty offers several control structures capable of conditionally and iteratively evaluating
passed-in data. These structures are introduced in this section.
The if Function
Smarty??™s if function operates much like the identical function in the PHP language.
As with PHP, a number of conditional qualifiers are available, all of which are displayed
here:
A simple example follows:
{* Assume $dayofweek = 6. *}
{if $dayofweek > 5}
Gotta love the weekend!
{/if}
??? eq ??? is not odd
??? gt ??? div by
??? gte ??? even by
??? ge ??? not
??? lt ??? mod
??? lte ??? odd by
??? le ??? ==
??? ne ??? !=
??? neq ??? >
??? is even ??? <
??? is not even ??? <=
??? is odd ??? >=
CHAPTER 19 ?– TEMPLAT ING WITH SMARTY 485
Consider another example. Suppose you want to insert a certain message based on
the month. The following example uses conditional qualifiers and elseif and else to
carry out this task:
{if $month < 4}
Summer is coming!
{elseif $month ge 4 && $month <= 9}
It's hot out today!
{else}
Brrr.
