织梦dedecms手机站m目录下不生成index.html实现动态更新

用dedecms会手机站首页不更新的苦恼，每次PC更新，要去删除m目录下的index.html，手机站首页才会更新，这样很麻烦，通过以下修改，让手机站首页是动态的，不生成index.html，PC端更新后，手机端首页自动更新。

把\m\index.php里面的

$row['showmod'] = isset($row['showmod'])? $row['showmod'] : 0;
if ($row['showmod'] == 1)
{
   $pv->SaveToHtml(dirname(__FILE__).'/index.html');
   include(dirname(__FILE__).'/index.html');
   exit();
} else {
   $pv->Display();
   exit();
}

改成

$pv->SetTemplet($cfg_basedir . $cfg_templets_dir . "/" . $row['templet']);
$pv->Display();
exit();

 

Dede实现1次同时一级、二级、三级栏目循环调用

一、修改文件：\include\taglib目录下的channel.lib.php，请将以下代码全部复制替换上述文件

function lib_channel_son($ctag,$typeid = 0,$dsql2)

二、在模板调用实例：
{dede:channel type='son' typeid='改成你的大栏目ID'}
              [field:typename/]
                    <ul>
                    [field:sonchannel0]
                    <li><a href="[field:typelink/]">[field:typename/]</a></li>
                         [field:sonchannel1]
                        <li><a href="[field:typelink/]">---[field:typename/]</a></li>
                             [field:sonchannel2]
                            <li><a href="[field:typelink/]">===[field:typename/]</a></li>
                                [field:sonchannel3]
                                <li><a href="[field:typelink/]">===[field:typename/]</a></li>
                                 [/field:sonchannel3]
                             [/field:sonchannel2]
                         [/field:sonchannel1]
                    [/field:sonchannel0]
                    </ul>
 {/dede:channel}
模板调用    [field:sonchannel0] [/field:sonchannel0] 这个是用来取子栏目用的（使用[sonchannel+数字] 作为标签名是为了防止嵌套的时候无法正确解析标签）这个的作用就是当你的栏目有很多子栏目 无限分级的时候方便你取子栏目的。
