{while} loops in Smarty have much the same flexibility as PHP while statements, with a few added features for the template engine. Every {while} must be paired with a matching {/while}. All PHP conditionals and functions are recognized, such as ||, or, &&, and, is_array(), etc.

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.

Qualifier Alternates Syntax Example Meaning PHP Equivalent
== eq $a eq $b equals ==
!= ne, neq $a neq $b not equals !=
> gt $a gt $b greater than >
< lt $a lt $b less than <
>= gte, ge $a ge $b greater than or equal >=
<= lte, le $a le $b less than or equal <=
===   $a === 0 check for identity ===
! not not $a negation (unary) !
% mod $a mod $b modulous %
is [not] div by   $a is not div by 4 divisible by $a % $b == 0
is [not] even   $a is not even [not] an even number (unary) $a % 2 == 0
is [not] even by   $a is not even by $b grouping level [not] even ($a / $b) % 2 == 0
is [not] odd   $a is not odd [not] an odd number (unary) $a % 2 != 0
is [not] odd by   $a is not odd by $b [not] an odd grouping ($a / $b) % 2 != 0

Example 132. {while} loop

{while $foo > 0}


The above example will count down the value of $foo until 1 is reached.
