聪明的分配变量
我试图通过这样做在我的 .tpl 中分配一个变量，
{assign var="image" value="images/stores/{$location.storename|regex_replace:"/[' ']/":"-"|lower}.jpg"}
但是我收到了这个错误，
Smarty 错误：[stores/view-store.tpl 第 135 行]：语法错误：无效属性名称：'|lower'
如何停止此错误，但仍将返回信息的大小写改为小写？
I am trying to assing a variable in my .tpl by doing this,
{assign var="image" value="images/stores/{$location.storename|regex_replace:"/[' ']/":"-"|lower}.jpg"}
however I am getting this error,
Smarty error: [in stores/view-store.tpl line 135]: syntax error: invalid attribute name: '|lower'
How Can i stop this error but still drop the casing of the returned info to lowercase?

即使你降价了，你仍然会遇到问题。 {} 块内不能包含 {} 块。也不能将“”嵌套在“”中。

查看该页面，查看复杂的示例。您将使用类似的内容
这可能对您也有用：
http:// /www.smarty.net/docs/en/language.function.eval.tpl
但最终，您应该在 PHP 端执行此操作，逻辑和代码并不意味着位于模板中，除非确实存在没有其他选择。
Even if you take lower off you're still going to have problems. You can't have a {} block inside a {} block. Nor can you have "" nested in "".

Look at that page, check out the complex example. You'll use something like
This might also be useful for you:

Ultimately though, you should be doing that on the PHP side, logic and code is not meant to be in the template unless there really is no other choice.
