CODE: 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. "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","==","!=",">", "<","<=",">=" are all valid conditional qualifiers, and must be separated from surrounding elements by spaces. |
[PHP]
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}
[/PHP]
