下面是调用函数

/*当前位置*/

function getposition($id){ 

$path = M('terms')->where(array('term_id'=>$id))->getField('path'); 

$str = ''; 

if(!empty($path)){ $path = explode('-', $path); 

foreach ($path as $key => $value) { 

if($value==0){ $str = $str . '<a href="' . __ROOT__ . '">HOME</a>&gt;'; 

}else{ 

$name = M('terms')->where(array('term_id'=>$value))->getField('name'); $str = $str . '<a href="' . __ROOT__ . '">' . $name . '</a>&gt;'; }

} 

} 

return $str;

}
