php smarty函数扩展_php模板_脚本之家

扩展函数放到 */Smarty/libs/plugins目录下，文件命名格式 modifier.xxxx.php,函数名格式function smarty_modifier_xxxx

中文截取 modifier.cn_truncate.php
代码如下:
function smarty_modifier_cn_truncate($string, $strlen = 20, $etc = '...',
$keep_first_style = false)
{
$strlen = $strlen*2;
$string = trim($string);
if ( strlen($string) return $string;
}
$str = strip_tags($string);
$j = 0;
for($i=0;$iif(ord(substr($str,$i,1))>0xa0) $j++;
}
if($j%2!=0) $strlen++;
$rstr=substr($str,0,$strlen);
if (strlen($str)>$strlen ) {$rstr .= $etc;}
if ( $keep_first_style == true && ereg('^$',$string) ) {
if ( strlen($str) return $string;
}
$start_pos = strpos($string,substr($str,0,4));
$end_pos = strpos($string,substr($str,-4));
$end_pos = $end_pos+4;
$rstr = substr($string,0,$start_pos) . $rstr . substr($string,$end_pos,strlen($string));
}
return $rstr;
}

modifier.ubb.php
代码如下:
function smarty_modifier_ubb($str) {
$ubbs['quote'][0] = '/\[quote\](.*?)\[\/quote\]/s';
$ubbs['quote'][1] = '
