dedecms独立模型分页功能的完好
dedecms事实上在架构方面没什么问题，可是预计里面有些功能是新手做的吧，有非常多待完好的地方，比方分页功能。从代码能够直接看出当时的负责人有敷衍了事的心里。
dede的分页假设有两个页码显示的话，无法显示出总的文章数，举个样例：
在普通文章模型以下，列表的分页是这种：
可是在独立模型中就成了这样了
最后面的共*页*条的信息不见了。相信遇到这个问题的同学首先想到的是自己哪里用错了，事实上不是，dede独立模型这里的代码是偷工减料了的。处理独立模型列表的代码在arc.sglistview.class.php中，我们比較下相同负责显示分页的代码段，独立模型和普通模型中有什么差别：
普通文章模型：

细致观察 普通模型中在28行左右的位置多了句$maininfo = "<li><span class=\"pageinfo\">共 <strong>{$totalpage}</strong>页<strong>".$this->TotalResult."</strong>条</span></li>\r\n";而在独立模型中则没有。
并且在最后，普通模型中将$maininfo的值增加了$plist字符串中。（更细节的地方是普通模型还推断了标签中是否有info属性来决定是否增加：
|
1
|
if(preg_match('/info/i', $listitem)) $plist .= $maininfo; |
）独立模型中这些都省了。
要将独立模型改动过来非常easy。只是“普通模型还推断了标签中是否有info属性来决定是否增加”这点我就不去实现了，这里不推断直接再不论什么情况下都增加maininfo：
