dedecms其实在架构方面没什么问题,但是估计里面有些功能是新手做的吧,有很多待完善的地方,比如分页功能,从代码可以直接看出当时的负责人有敷衍了事的心里。
dede的分页如果有两个页码显示的话,无法显示出总的文章数,举个例子:
在普通文章模型下面,列表的分页是这样的:
但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,其实不是,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,我们比较下同样负责显示分页的代码段,独立模型和普通模型中有什么区别:
普通文章模型:
/**

* @param string $list_len 列表宽度
* @param string $list_len 列表样式
* @return string

$list_len=3;

$totalpage = ceil($this->TotalResult/$this->PageSize);

$maininfo = "<li><span class=\"pageinfo\">共 <strong>{$totalpage}</strong>页<strong>".$this->TotalResult."</strong>条</span></li>\r\n";

仔细观察 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>".$this->TotalResult."</strong>条</span></li>\r\n";而在独立模型中则没有。
而且在最后,普通模型中将$maininfo的值加入了$plist字符串中。(更细节的地方是普通模型还判断了标签中是否有info属性来决定是否加入:
if(preg_match('/info/i', $listitem)) $plist .= $maininfo;
)独立模型中这些都省了。
要将独立模型修改过来很简单,不过“普通模型还判断了标签中是否有info属性来决定是否加入”这点我就不去实现了,这里不判断直接再任何情况下都加入maininfo:
