在truncate smarty中显示一个链接

Question

在smarty中，我们可以使用它来缩短文本输出：

{$articleTitle}
{$articleTitle|truncate}
{$articleTitle|truncate:30}
{$articleTitle|truncate:30:""}
{$articleTitle|truncate:30:"---"}
{$articleTitle|truncate:30:"":true}
{$articleTitle|truncate:30:"...":true}
{$articleTitle|truncate:30:'..':true:true}

结果将是这样的：

Two Sisters Reunite after Eighteen Years at Checkout Counter.
Two Sisters Reunite after Eighteen Years at Checkout Counter.
Two Sisters Reunite after...
Two Sisters Reunite after
Two Sisters Reunite after---
Two Sisters Reunite after Eigh
Two Sisters Reunite after E...
Two Sisters Re..ckout Counter.

我想要显示的是：“... <a href="{$url}">read more</a>” 当你将它应用于代码时，它将是这样的：

{$articleTitle|truncate:30:"... <a href="{$url}">read more</a>":true}

但这不起作用。我怎样才能使它发挥作用？

Answer 1

首先尝试在邮件中用单引号替换双引号：

{$articleTitle|truncate:30:"... <a href='{$url}'>read more</a>":true}

如果没有帮助，请尝试为您的消息使用其他变量：

{assign var=readMoreText value="... <a href='{$url}'>read more</a>"}   
{$articleTitle|truncate:30:$readMoreText:true}
