帝国CMS如何调用带下拉菜单的导航

帝国CMS建网站时，使用程序自带的菜单标签，可以生成纯A的菜单。

[!--class.menu--]

如果只想调用一级导航，可以使用以下的代码：

<ul class="topnav">

<li class="<?= ($GLOBALS['navclassid'] ? '' : 'current-menu-item') ?>"><a href="[!--news.url--]">网站首页</a></li>

<?php

// 查询一级菜单

$sql = $empire->query("select classid, sonclass, classname, islast, islist from {$dbtbpre}enewsclass where bclassid=0 and showclass=0 order by myorder asc LIMIT 20");

while ($primaryMenu = $empire->fetch($sql)) {

$classUrl = sys_ReturnBqClassname($primaryMenu, 9);

$topClass = '';

$featherClass = explode('|', $class_r[$GLOBALS['navclassid']]['featherclass']);

$topbclassid = $featherClass[1] ? $featherClass[1] : $GLOBALS['navclassid'];



// 判断是否为当前菜单

if ($topbclassid == $primaryMenu['classid']) {

$topClass = 'current-menu-item';

}



?>

<li class="navbar-item <?=$topClass?>"><a href="<?=$classUrl?>"><?=$primaryMenu['classname']?></a></li>

<?php }?>

</ul>

如果想制作带二级菜单，需要显示带下拉功能的导航菜单，使用默认菜单标签是无法实现的。可以使用以下的代码来实现。( LIMIT 20 可以控制数量)

<ul class="topnav">

<li class="<?= ($GLOBALS['navclassid'] ? '' : 'current-menu-item') ?>"><a href="[!--news.url--]">网站首页</a></li>

<?php

// 查询一级菜单

$sql = $empire->query("select classid, sonclass, classname, islast, islist from {$dbtbpre}enewsclass where bclassid=0 and showclass=0 order by myorder asc LIMIT 20");

while ($primaryMenu = $empire->fetch($sql)) {

$classUrl = sys_ReturnBqClassname($primaryMenu, 9);

$topClass = '';

$featherClass = explode('|', $class_r[$GLOBALS['navclassid']]['featherclass']);

$topbclassid = $featherClass[1] ? $featherClass[1] : $GLOBALS['navclassid'];



// 判断是否为当前菜单

if ($topbclassid == $primaryMenu['classid']) {

$topClass = 'current-menu-item';//当前样式

}



//判断是否有二级菜单

if ($primaryMenu['islast'] == 0) {//有下拉

$fuliclass=" ";

$fuaclass=" ";

}else{

$fuliclass=" ";

$fuaclass=" ";

}



?>

<li class="<?=$topClass?> <?=$fuliclass?>"><a class="<?=$fuaclass?>" href="<?=$classUrl?>"><?=$primaryMenu['classname']?></a>



<?php

//判断是否有二级菜单

if ($primaryMenu['islast'] == 0) { ?>

<ul class="sub-menu">

<?

$sql2 = $empire->query("select classid, classname from {$dbtbpre}enewsclass where bclassid={$primaryMenu['classid']} and showclass=0 order by myorder asc");

$subMenuStr = "";

while ($secondaryMenu = $empire->fetch($sql2)) {

$classUrl2 = sys_ReturnBqClassname($secondaryMenu, 9);

?>

<li><a href="<?=$classUrl2?>"><?=$secondaryMenu['classname']?></a></li>

<?

}

?>

</ul>

<?php }

?>



</li>

<?php }?>

</ul>
