首先,非常感谢所有试图在这里提供帮助的人,一些答案让我头疼不已。 其次,请假设我几乎不懂任何语言。
我正在尝试使用 cssmenumaker.com/blog/wordpress-中的 apycom.com/menus/12-forest-green.html 菜单作为wordpress动态菜单 cssmenumaker.com/blog/wordpress- 3-下拉菜单教程即可。
一切看起来都不错,但是子菜单不起作用。这是一张图片http://i.imgur.com/LHGhYyn.jpg。
修改
也许我不太清楚。让我详细解释一下
第1步:我将此自定义walker类添加到我的functions.php
class CSS_Menu_Maker_Walker extends Walker {
var $db_fields = array( 'parent' => 'menu_item_parent', 'id' => 'db_id' );
function start_lvl( &$output, $depth = 0, $args = array() ) {
$indent = str_repeat("\t", $depth);
$output .= "\n$indent<ul>\n";
}
function end_lvl( &$output, $depth = 0, $args = array() ) {
$indent = str_repeat("\t", $depth);
$output .= "$indent</ul>\n";
}
function start_el( &$output, $item, $depth = 0, $args = array(), $id = 0 ) {
global $wp_query;
$indent = ( $depth ) ? str_repeat( "\t", $depth ) : '';
$class_names = $value = '';
$classes = empty( $item->classes ) ? array() : (array) $item->classes;
/* Add active class */
if(in_array('current-menu-item', $classes)) {
$classes[] = 'active';
unset($classes['current-menu-item']);
}
/* Check for children */
$children = get_posts(array('post_type' => 'nav_menu_item', 'nopaging' => true, 'numberposts' => 1, 'meta_key' => '_menu_item_menu_item_parent', 'meta_value' => $item->ID));
if (!empty($children)) {
$classes[] = 'has-sub';
}
$class_names = join( ' ', apply_filters( 'nav_menu_css_class', array_filter( $classes ), $item, $args ) );
$class_names = $class_names ? ' class="' . esc_attr( $class_names ) . '"' : '';
$id = apply_filters( 'nav_menu_item_id', 'menu-item-'. $item->ID, $item, $args );
$id = $id ? ' id="' . esc_attr( $id ) . '"' : '';
$output .= $indent . '<li' . $id . $value . $class_names .'>';
$attributes = ! empty( $item->attr_title ) ? ' title="' . esc_attr( $item->attr_title ) .'"' : '';
$attributes .= ! empty( $item->target ) ? ' target="' . esc_attr( $item->target ) .'"' : '';
$attributes .= ! empty( $item->xfn ) ? ' rel="' . esc_attr( $item->xfn ) .'"' : '';
$attributes .= ! empty( $item->url ) ? ' href="' . esc_attr( $item->url ) .'"' : '';
$item_output = $args->before;
$item_output .= '<a'. $attributes .'>';
$item_output .= $args->link_before . apply_filters( 'the_title', $item->title, $item->ID ) . $args->link_after;
$item_output .= '</a>';
$item_output .= $args->after;
$output .= apply_filters( 'walker_nav_menu_start_el', $item_output, $item, $depth, $args );
}
function end_el( &$output, $item, $depth = 0, $args = array() ) {
$output .= "</li>\n";
}
}
第2步:添加图片文件夹,menu.js&amp; jquery.js到我的主题文件夹。还将以下菜单css添加到我的主题样式表中。
/**

步骤3:在外观上制作菜单&gt;菜单并命名为'menu'并将此代码添加到我的模板中以打印菜单
<?php
wp_nav_menu(array(
'menu' => 'menu',
'container_id' => 'menu',
'link_before' => '<span>',
'link_after' => '</span>',
'walker' => new CSS_Menu_Maker_Walker()
));
?>
现在您可以从上图中看到,子菜单卡在菜单顶部并始终可见。但是,如果没有子菜单,菜单将完美地工作,包括lavalamp效果。
我希望我现在足够清楚了。不幸的是@ 5wordpressthemes的答案没有帮助。 谢谢你的时间。
答案 0 :(得分:0)
1.在您的Worpress仪表板中,转到* 外观 - 菜单 屏幕并开始创建菜单。 *
2.添加左栏中的菜单项
第3。将此代码添加到您的页面以显示菜单
<?php $defaults = array(
'theme_location' => '',
'menu' => 'Your menu name',
'container' => 'ul',
'container_class' => 'menu-{menu slug}-container',
'container_id' => 'div',
'menu_class' => 'menu',
'menu_id' => 'menu-{menu slug}[-{increment}]',
'echo' => true,
'fallback_cb' => 'wp_page_menu',
'before' => '',
'after' => '',
'link_before' => '',
'link_after' => '',
'items_wrap' => '<ul id="%1$s" class="%2$s">%3$s</ul>',
'depth' => 0,
'walker' => ''
); ?>
<?php wp_nav_menu( $defaults ); ?>
<强> 4。将css代码保存在..css文件中,如menu.css,并将此文件链接到header.php
<link rel="stylesheet" href="<?php bloginfo('template_url'); ?>/menu.css" type="text/css" media="screen" />
所有文件必须位于主题文件夹

答案 1 :(得分:0)
我找到了一个适合我的解决方案。我在这里张贴它,任何人都在寻找它。由于我对代码一点都不熟悉,所以不得不为它而努力。
我注意到,对于子菜单,wordpress会<ul class="sub-menu">
所以我改变了我的助行器
function start_lvl( &$output, $depth = 0, $args = array() ) {
$indent = str_repeat("\t", $depth);
$output .= "\n$indent<ul>\n";
}
function end_lvl( &$output, $depth = 0, $args = array() ) {
$indent = str_repeat("\t", $depth);
$output .= "$indent</ul>\n";
}
到
function start_lvl( &$output, $depth = 0, $args = array() ) {
$indent = str_repeat("\t", $depth);
$output .= '<div><ul class="sub-menu">';
}
function end_lvl( &$output, $depth = 0, $args = array() ) {
$indent = str_repeat("\t", $depth);
$output .= '</ul></div>';
}
可能不是一个好的解决方案,但现在我可以从外观&gt;菜单中创建子菜单和子菜单。
然而,现在我的箭头图像css不再起作用,但我想我可以忍受。
div#menu ul ul a.parent {
background: url(images/submenu-pointer.png) no-repeat right top;
-background: url(images/submenu-pointer.gif) no-repeat right top;
margin-right: -1px;
}
div#menu ul ul a.parent span {
padding-right: 26px;
}
div#menu ul ul a.parent:hover {
background: url(images/submenu-pointer-hover.gif) no-repeat right top;
-background: url(images/submenu-pointer.gif) no-repeat right top;
}
快速提问
我的下拉列表隐藏在我的内容背后。我尝试过增加z-index,但它不起作用,当我将position: absolute
更改为position: relative
或删除它时,它会破坏子菜单。
对此的任何帮助都将受到高度赞赏。
