{{'param1'|functionName}}例如
{{$tmpStr|
strlen
}}2个参数时候:
{{'param1'|functionName:'param2'}}
{$tmpStr|substr:'1'}多个参数时候:
{{'param1'|functionName:'param2':'param3'..}}
{{$tmpStr|substr:'1':'2'}}
{{'a'|str_replace:'A':$tmpStr}}如下代码php分配给tmpStr为空或没分配;那么smarty中输出0。这个是调用了php的内置函数strlen
:
$smarty->assign('tmpStr','');
smarty代码:
{{if $tmpStr|strlen > 0 }}
1
{{else}}
0
{{/if}}
通过php内置的函数is_array和count求得数组长度,如下的代码输出5
php代码:
$smarty->assign('tmpArr',array(1,2,3,4,5));smarty代码:
{{if $tmpArr|is_array && $tmpArr|@count > 0}}
{{$tmpArr|@count}}{{else}}
0
{{/if}}如下的代码是将tmpStr中的b替换为c
$smarty->assign('tmpStr','abb');
{{'b'|str_replace:'c':$tmpStr}}输出:
acc
$smarty->assign('tmpStr','abb');
{{$tmpStr|substr:'1'}}输出:
bb
{{$tmpStr|substr:'1':'1'}}输出:
b
