functionA是一个自定义smarty的插件,这个函数有一个参数url.
但是url的值由字符串1,变量$onetopic.id,字符串2组成。

{fuctionA url='str2{$onetopic.id}str2'}
Copy after login

{fuctionA url='str2'.'$onetopic.id'.'str2'}
Copy after login

我试了以上几种形式都不行!大牛指教一下吧!


回复讨论(解决方案)

{fuctionA url="str2{$onetopic.id}str2"}

都不行

换吧,分成多个参数,在函数里再改动下。

{fuctionA url="str2"|cat:$onetopic.id|cat:"str2"}

cat是smarty的字符串连接函数,你多试试,好久不用smarty了

感谢 4 5 楼

百度搜到的答案,感谢LZ分享,这里做个标记,
更复杂的应用:

<!--{tag t_id=48 where="id="|cat:(","|explode:base64_decode($ci_uri.4)|end|default:8) html_type='detail'}-->
Copy after login
