是否有限制显示字数的功能啊

有！用truncate

从字符串开始处截取某长度的字符.默认是80个.

你也可以指定第二个参数作为追加在截取字符串后面的文本字串.该追加字串被计算在截取长度中。

默认情况下,smarty会截取到一个词的末尾。

如果你想要精确的截取多少个字符,把第三个参数改为"true"

CODE:

index.php:

$smarty =new Smarty;

$smarty->assign('articleTitle','Two Sisters Reunite after Eighteen Years at CheckoutCounter.');

$smarty->display('index.tpl');

index.tpl:

{$articleTitle}

{$articleTitle|truncate}

{$articleTitle|truncate:30}

{$articleTitle|truncate:30:""}

{$articleTitle|truncate:30:"---"}

{$articleTitle|truncate:30:"":true}

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

OUTPUT:

Two Sisters Reunite after Eighteen Years at Checkout Counter.
