用帝国CMS自定义标签实现当前栏目高亮
<div><p>
一番测试下来,雪①找到了自己觉得方便的方法, 特记录在此。 <br>
1、因为要用到自定义标签,所以首先要在eclassuserfun.php 加入一个自定义函数, 即 <br>
</p>
<div>
代码如下:</div>
<div id="phpcode12">
<br>
//取得顶级栏目ID函数 <br>
function user_GetTopBclassid($classid){ <br>
global $class_r; <br>
$fr=explode('|',$class_r[$classid]); <br>
$topbclassid=$fr?$fr:$classid;//取得第一级栏目id <br>
return $topbclassid; <br>
} </div>
<p>
<br><span>2、接下来用灵动标签调用导航部分,用<?=user_GetTopBclassid($GLOBALS)?>动态获取当前栏目id以及父栏目id。 </span></p>
<blockquote>
<ol>
<li>
<span><span><ul </span><span>class</span><span>=</span><span>"menu"</span><span>> </span></span>
</li>
<li>
<span><li id=<span>"current"</span><span>><a href=</span><span>"/"</span><span>>首页</a></li> </span></span>
</li>
<li>
<span><!--灵动标签开始--> </span>
</li>
<li>
<span>enewsclass where bclassid=0 order by classid'</span><span>,0,24,0}] </span></span>
</li>
<li>
<span><li id=<span>"current<?=$bqr?>"</span><span>><a href=</span><span>"<?=$public_r?><?=$bqr?>"</span><span> title=</span><span>"<?=$bqr?>"</span><span> target=</span><span>"_self"</span><span> ><?=$bqr?></a></li> </span></span>
</li>
<li>
<span> </span>
</li>
<li>
<span><style type=<span>"text/css"</span><span>><!--加入动态css样式--> </span></span>
</li>
<li>
<span><!-- </span>
</li>
<li>
<span><span>#menu #current<?=user_GetTopBclassid($GLOBALS)?> /*---动态获取当前栏目id -*/ </span><span> </span></span>
</li>
<li>
<span>{background:url(/images/2008a/bg_menu_on_left.gif) no-repeat; font-weight:bold;} </span>
</li>
<li>
<span><span>#menu #current<?=user_GetTopBclassid($GLOBALS)?> a,#menu&nbsp;#current<?=user_GetTopBclassid($GLOBALS)?> a:hover{color:#000; background:url(/images/2008a/bg_menu_on_right.gif) no-repeat right;} </span><span> </span></span>
</li>
<li>
<span>--> </span>
</li>
<li>
<span></style> </span>
</li>
<li>
<span><!--灵动标签结束--> </span>
</li>
</ol>
</blockquote>
<p>
<br><br><span>3、在模板变量中制作一个变量, 如 [!--temp.tab--] 在其中加入第2步的代码, 就可以在首页及列表页调用啦, </span><br><br><span>引用wc在论坛的一个回复 <?=user_GetTopBclassid($GLOBALS)?> </span><br><span>当为首页的时候当前栏目是为空即channle </span><br><span>当前为一级栏目时，则为channle当前栏目id </span><br><span>当有栏目为非一级栏目，则为channle一级父栏目id </span><br><br><span>封面模板、列表模板、内容模板下都有效.</span></p>
</div>
