The IF statement in Smarty is as flexible and easy to use as the IF statement in PHP, and adds several features to fit the template engine. If must appear in pairs of/if. You can use the else and elseif clauses. You can use the following conditions to modify words: EQ, NE, neq, GT, LT, LTE, Le, GTE, GE, is even, is odd, is not even, is not odd, not, MoD, div by, even by, odd by, = =,!=, >, <, <=, >=. You must use these modifiers with a variable or constant in an empty space.

{* An example with "or" logic *}
{if $name eq ' Fred ' or $name eq ' Wilma '}
...
{/if}

{* Same as above *}
{if $name = = "Fred" | | $name = = "Wilma"}
...
{/if}

Must be separated from surrounding elements by spaces *}
{if $name = = "Fred" | | $name = = "Wilma"}
...
{/if}


{* Parenthesis are allowed *}
{if ($amount < 0 or $amount > 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 are 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. *}
