【伍佰网站目录】通过字符截取让网站变得整洁

 很多用伍佰网站目录和用35DIR目录的朋友都知道，每个收录的网站的标题如果自己不限制标题，会让网站很难看，长的非常长，甚至引起错位，在这里伍佰告诉大家如何用截取的方式限制标题的长度


修改方式:

在你的模版页面，需要截取限制标题的长度地方

例如{#$art.art_title#} 把这个标签里面添加{#$art.art_title|truncate:限制的字数:""#}

就可以了

关于truncate函数的使用方法参考如下：

truncate
截取


Parameter Position参数位置     Type参数类型     Required必需     Default默认     Description描述
1     integer     No     80     This determines how many characters to truncate to.
截取字符的数量
2     string     No     ...     This is the text to append if truncation occurs.
截取后追加在截取词后面的字符串
3     boolean     No     false     This determines whether or not to truncate at a word boundary (false), or at the exact character (true).
是截取到词的边界（假）还是精确到字符（真）


This truncates a variable to a character length, default is 80.
As an optional second parameter, you can specify a string of text to display at the end if the variable was truncated. The characters in the string are included with the original truncation length.
By default, truncate will attempt to cut off at a word boundary.
If you want to cut off at the exact character length, pass the optional third parameter of true.

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"

Example 5-21. truncate
例.截取

index.php:

$smarty = new Smarty;
$smarty->assign('articleTitle', 'Two Sisters Reunite after Eighteen Years at Checkout Counter.');
$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.
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...
