Example 7-11. if statements 例 7-11. if 语句演示 {if $name eq Fred} Welcome Sir. {elseif $name eq Wilma} Welcome Maam. {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 $nameFred || $nameWilma} ... {/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., 0even, 1even, 2odd, 3odd, 4even, 5even, etc. *} {if $var is even by 2} ... {/if} {* 0even, 1even, 2even, 3odd, 4odd, 5odd, etc. *} {if $var is even by 3} ... {/if} 时间戳 而在smarty模板中如$time是php文件中assign过来的时间戳在模板文件中写法为 {$time|date_format:%Y-%m-%d %H:%M:%S} 同样对应的输出格式为“年-月-日 时分秒”。 转载于:https://my.oschina.net/u/162418/blog/123049
