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. Everyifmust be paired with an/if.elseandelseifare 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.

Smarty 中的 if 语句和 php 中的 if 语句一样灵活易用,并增加了几个特性以适宜模板引擎. if 必须于 /if 成对出现. 可以使用 else 和 elseif 子句. 可以使用以下条件修饰词: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、==、!=、>、<、<=、>=. 使用这些修饰词时必须和变量或常量用空格格开.

Example 7-11. if statements
例 7-11. if 语句演示

{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}
