我使用CCTM plugin 和复制/粘贴存档。php存档车辆。php，但这导致我的标题中出现错误：
Warning: in_array() expects parameter 2 to be array, null given in /home/.../public_html/wp-includes/nav-menu-template.php on line 439
每个主菜单项（没有子菜单）都会重复相同的错误。
如果我移除存档车辆。php和使用归档查看相同的帖子。php没有出现错误。
为什么会这样？
Update
导航菜单模板第439行。php是
in_array( $parent_item->object_id, $queried_object->ancestors )
print_r($queried_object) 就在第439行生成以下内容之前-没有“祖先”键：

最合适的回答,由SO网友:chrisguitarguy 整理而成
在第439行生成以下内容之前打印\\r（$queryed\\u object）-没有“祖先”键：
当您进行post类型存档调用时get_queried_object （代码可能会这样做）或使用WP_Query::$queried_object 返回post类型“object”。所有这些都是post类型注册时使用的参数。
的相关位nav-menu-template.php 在WordPress 3.6中。
<?php
function _wp_menu_item_classes_by_context( &$menu_items ) {
// ...
foreach ( (array) $menu_items as $key => $parent_item ) {
// ...
if (
isset( $parent_item->type ) &&
(
// ancestral post object
(
\'post_type\' == $parent_item->type &&
! empty( $queried_object->post_type ) &&
is_post_type_hierarchical( $queried_object->post_type ) &&
in_array( $parent_item->object_id, $queried_object->ancestors ) &&
$parent_item->object != $queried_object->ID
) ||
// ancestral term
(
\'taxonomy\' == $parent_item->type &&
isset( $possible_taxonomy_ancestors[ $parent_item->object ] ) &&
in_array( $parent_item->object_id, $possible_taxonomy_ancestors[ $parent_item->object ] ) &&
(
! isset( $queried_object->term_id ) ||
$parent_item->object_id != $queried_object->term_id
)
)
)
) {
$classes[] = empty( $queried_object->taxonomy ) ? \'current-\' . $queried_object->post_type . \'-ancestor\' : \'current-\' . $queried_object->taxonomy . \'-ancestor\';
}
// ...
}
// ...
}
这个钻头
! empty( $queried_object->post_type ) 应在柱式档案上评估为假。正在向查询的对象添加post类型。通过某种方式
I mean your plugin 这是
_doing_it_wrong. 看看
CCTM::register_custom_post_types() 和
CCTM::$default_post_type_def.
任何被传递到register_post_type 只是作为参数存储在post类型的全局数组中。
如果我这样做：
register_post_type(\'some_type\', array(\'this_is_not_a_wp_arg\' => true));
在上
archive-some_type.php 我可以查一下
this_is_not_a_wp_arg.
<?php
// archive-some_type.php
var_dump(get_queried_object()->this_is_not_a_wp_arg); // true
因为你的插件碰巧
post_type 在arguments数组中，它会使WP求值
! empty( $queried_object->post_type ) 这是真的。这不是
archive.php 因为
$query_object->post_type 为空。因为它应该在任何post类型的存档上。不幸的是，CCTM插件作者不理解传递“保留”字的后果，如
post_type 作为论点的关键。这就是为什么在事物前面加前缀很重要。
EDIT
一个非常老套的解决方法是
init 非常晚，并循环浏览所有帖子类型。如果
post_type 参数已设置，请将其删除。这可能会破坏插件在管理区域的其他功能。
<?php
add_action(\'init\', \'wpse115604_fix\', 10000);
function wpse115604_fix()
{
foreach (get_post_types(array(), \'objects\') as $type) {
if (isset($type->post_type)) {
unset($type->post_type);
}
}
}
这将避免您必须编辑插件本身。我会这样做，然后将问题报告给插件作者。如果/当它在将来的版本中得到修复，您将能够删除该代码。
TL;DR: CCTM向名为post_type 它扰乱了事物的秩序，并在运动中设置了一系列错误。
