我试图在我的模板文件中放置一个WordPress菜单。我发现使用wp_nav_menu不舒服，因为它输出的标记与我的静态HTML模板不兼容。我知道我可以使用自定义菜单walker类来修改wp_nav_menu的标记。但相反，我只想使用菜单名称及其相应的URL并将其放在我的模板中。为此，我使用this function来获取菜单的所有属性/属性的数组。

我该怎么做？
我目前正在努力解决这些代码行
function mt_get_menu_items($menu_name) {
if ( ( $locations = get_nav_menu_locations() ) && isset( $locations[ $menu_name ] ) ) {
$menu = wp_get_nav_menu_object( $locations[ $menu_name ] );
return wp_get_nav_menu_items($menu->term_id);
}
}
$menu_items = mt_get_menu_items ('main_menu');
<nav id="nav">
<ul>
<?php if (isset ($menu_items) ) : ?>
<?php foreach ( (array) $menu_items as $key => $menu_item ) : ?>
<?php // $menu_item_array = get_object_vars($menu_item[$key]);
$menu_object = $menu_item[$key];
// this line is 98
?>
<li>
// this line is 101
<a href="<?php $menu_object->url; ?>" class="active"><?php $menu_object->post_title; ?></a>
</li>
<?php endforeach; ?>
<?php endif; ?>
</ul>
</nav>
这会产生此错误：
致命错误：未捕获错误：无法在D：\ xampp \ htdocs \ mySite \ wp-content \ themes \ mySite \ header.php：98
中使用WP_Post类型的对象作为数组
答案 0 :(得分：11)
我将在此发布此答案以供参考......
使用foreach循环
foreach ($originalArray as $key => $data) {
$post_date = $data->post_date; // 2017-07-10 11:50:32
}
因为要访问对象内的数据，请使用->。
例如：$data['post_date']到$data->post_date
答案 1 :(得分：2)
您正在检索某个对象，您可以将其转换为数组，如下所示：
function object_to_array($obj) {
if(is_object($obj)) $obj = (array) $obj;
if(is_array($obj)) {
$new = array();
foreach($obj as $key => $val) {
$new[$key] = object_to_array($val);
}
}
else $new = $obj;
return $new;
}
