我已经从 Woocommerce--> Inventory 中检查了从我的 eshop 中隐藏“缺货”产品的选项。现在，我试图找出如何从只有缺货产品的类别列表菜单小部件中隐藏类别。任何的想法？提前致谢。我使用iks菜单插件。
我试过了
function exclude_categories( $category_list_args ) {
$args = array(
'hide_empty' => false,
'hierarchical' => true,
);
$product_categories = get_terms( 'product_cat', $args );
$exclude = array();
foreach ( $product_categories as $category ) {
$posts = get_posts( array( 'post_type' => 'product', 'posts_per_page' => -1, 'product_cat' => $category->slug, 'fields' => 'ids' ) );
$show_category = false;
foreach ( $posts as $post ) {
$product = new wC_Product( $post );
$visible_product = $product->is_visible();
if ( true === $visible_product ) {
$show_category = true;
break;
}
}
if ( false === $show_category ) {
$exclude[] = $category->term_id;
}
}
if ( ! empty( $exclude ) ) {
$category_list_args['exclude'] = implode( ',', $exclude );
unset( $category_list_args['include'] );
}
return $category_list_args;
}
add_filter( 'woocommerce_product_categories_widget_args', 'exclude_categories', 10, 1 );
我应该使用哪个钩子而不是 woocommerce_product_categories_widget_args ？我使用iks menus插件在手风琴上显示产品类别列表。上面的代码适用于 Woocommerce 产品类别小部件，但不适用于 iks 菜单小部件...
在iks菜单插件上，负责在widget侧边栏显示类别的函数是
private function get_WP_terms() {
$taxonomy = $this->get_taxonomy();
if ( $taxonomy ) {
$this->args = [
"taxonomy" => $taxonomy,
];
$this->save_args( [
"orderby",
"order",
"hide_empty",
"hierarchical",
"include",
"exclude",
"search",
"child_of",
"parent",
"childless",
] );
if ( version_compare( get_bloginfo( 'version' ), '4.5', '>=' ) ) {
$items = get_terms( $this->args );
} else {
$items = get_terms( $taxonomy, $this->args );
}
if ( is_array( $items ) ) {
if ( ! empty( $items ) ) {
$index = 0;
$show_posts = $this->settings_manager->get_value( "show_posts" );
/* Posts */
if ( $show_posts ) {
$post_type = Utils::get_post_type_by_taxonomy( $taxonomy );
$include = $this->settings_manager->get_value( "include" );
$has_include = ! empty( $include );
$posts = get_posts( [
'post_type' => $post_type,
'posts_per_page' => - 1,
'orderby' => 'date',
'order' => 'DESC',
'tax_query' => [
[
'taxonomy' => $taxonomy,
'operator' => $has_include ? 'IN' : 'EXISTS',
'terms' => $has_include ? Utils::get_terms_ids( $items ) : [],
]
],
'suppress_filters' => false // [Fix] WPML compatibility
] );
$posts_by_terms = [];
foreach ( $posts as $post ) {
$terms = get_the_terms( $post, $taxonomy );
if ( ! empty( $terms ) ) {
foreach ( $terms as $term ) {
if ( ! isset( $posts_by_terms[ $term->term_id ] ) ) {
$posts_by_terms[ $term->term_id ] = [];
}
$posts_by_terms[ $term->term_id ][] = $post;
}
}
}
}
foreach ( $items as $key => $item ) {
$id = (int) $item->term_id;
$link = get_term_link( $id );
$item_data = [
"id" => $id,
"title" => $item->name,
"link" => $link,
"parent" => (int) $item->parent,
"is_current" => $this->is_current_page_url( $link ) || $this->get_queried_object_term_id() === $id,
"is_term_includes_post" => $this->is_term_includes_post( $id, $this->get_taxonomy() ),
"is_page_includes_post" => false,
"index" => $index,
"is_expanded" => false,
"posts_count" => $item->count,
"is_post" => false,
"target" => null,
];
$index ++;
$this->data[] = $item_data;
if ( $show_posts ) {
if ( isset( $posts_by_terms[ $id ] ) ) {
$result_posts = $posts_by_terms[ $id ];
foreach ( $result_posts as $post ) {
$post_link = get_permalink( $post->ID );
$this->data[] = [
"id" => $post->ID,
"title" => $post->post_title,
"link" => $post_link,
"parent" => $id,
"is_current" => $this->is_current_page_url( $post_link ),
"is_term_includes_post" => false,
"is_page_includes_post" => false,
"index" => $index,
"is_expanded" => false,
"posts_count" => false,
"is_post" => true,
"target" => null,
];
$index ++;
}
}
}
}
}
我想我需要类似的东西
'meta_query' => array(
array(
'key' => '_stock_status',
'value' => 'instock',
'compare' => '=',
)
)
但我有点困惑...
答案 0 :(得分：0)
我们可以找到每个类别的帖子数的唯一方法是获取 Option Explicit
Sub EmailCC()
Dim xOTApp As Object
Dim xMItem As Object
Dim xCell As Range
Dim xRg As Range
Dim xEmailAddr As String
Dim xTxt As String
Dim w As Workbook
Dim sProject As Worksheet
Dim sContacts As Worksheet
Dim i As Integer
Dim column As Integer
Set w = ActiveWorkbook
Set sProject = w.Sheets(1)
Set sContacts = w.Sheets(2)
On Error Resume Next
column = sProject.Cells(3, 9).Value
If Not (IsNumeric(column)) Then Exit Sub
Set xOTApp = CreateObject("Outlook.Application")
i = 3
Do While Not sContacts.Cells(i, column).Value = ""
xEmailAddr = sContacts.Cells(i, column).Value & ";" & xEmailAddr
i = i + 1
Loop
Set xMItem = xOTApp.CreateItem(0)
With xMItem
.To = " "
.CC = xEmailAddr
.Display
End With
End Sub
的所有类别 (terms)。然后我们循环遍历它们 - 每次调用我的函数 product_cat 并传递 get_count。在 term_id 中，我们运行查询以获取与其关联的所有帖子，并且我们还传递帖子元 get_count。这将返回库存状态为库存的所有产品。然后我们返回 _stock_status = instock 属性 - IF 语句然后检查帖子计数是否大于 0。
