{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. 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 1000 ) and $volume >= #minVolAmt#} ... {/if} {* you can also embed php function calls *} {if count($var) gt 0} ... {/if} {* test if values are even or odd *} {if $var is even} ... {/if} {if $var is odd} ... {/if} {if $var is not odd} ... {/if} {* test if var is divisible by 4 *} {if $var is div by 4} ... {/if} {* test if var is even, grouped by two. i.e., 0=even, 1=even, 2=odd, 3=odd, 4=even, 5=even, etc. *} {if $var is even by 2} ... {/if} {* 0=even, 1=even, 2=even, 3=odd, 4=odd, 5=odd, etc. *} {if $var is even by 3} ... {/if} {* check for array. *} {if is_array($foo) } ...do something {/if} ]]>
