Smarty Manual
PrevChapter 7. Built-in FunctionsNext

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 are recognized, such as ||, or, &&, and, 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.

Example 7-11. if statements

{if $name eq "Fred"}
	Welcome Sir.
{elseif $name eq "Wilma"}
	Welcome Ma'am.
{else}
	Welcome, whatever you are.
{/if}

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

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

{* the following syntax will NOT work, conditional qualifiers
   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 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}
