未捕获的错误:不能将WP_Post类型的对象用作数组

我试图将WordPress菜单放在模板文件中。我发现使用wp_nav_menu很不舒服, 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浏览器类来修改wp_nav_menu的标记。但是, 我只想使用菜单名称及其相应的url并将其放置在我的模板中。为此, 我使用此函数获取菜单的所有属性/属性的数组。

这是此函数生成的代码…

我通过使用var_dump()找到了它。

                )

            [xfn] = 
        )

)

我的意图是获取” post_title”和” url”的值

我怎样才能做到这一点?

我目前正在努力处理这些代码行

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>

这将产生此错误:

致命错误:未捕获错误:无法将WP_Post类型的对象用作D:\ xampp \ htdocs \ mySite \ wp-content \ themes \ mySite \ header.php:98中的数组


#1


我将在此处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
}

因为要访问对象内部的数据, 请使用->。

例如:$ data [‘post_date’]至$ data-> post_date


#2


你正在检索对象, 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;       
}
