获取给定类别ID

的产品列表
我找不到正确的方法来获取给定类别ID(而非类别名称)的所有产品的列表.

我用来获取类别列表的代码如下,它可以正常工作:

$args = array( 'orderby' => $orderby, 'order' => $order, 'hide_empty' => 0, 'include' => $ids, 'parent' => 0, ); $categories = get_terms( 'product_cat', $args );

但是,现在对于给定的类别ID(例如47),我找不到获取其相关产品的方法.我尝试了以下方法:

$args = array( 'posts_per_page' => 5, 'offset'=> 1, 'category' => 47 ); $products = get_posts( $args ); echo var_dump($products);

调试$products数组总是返回0,这是错误的,因为我知道ID为47的类别下有一些产品.有什么想法可以解决我的代码吗?
I couldn't find the right way to get the list of all products for a given category ID (not category name).

The code I am using to get the categories list is the following, it works fine:

$args = array( 'orderby' => $orderby, 'order' => $order, 'hide_empty' => 0, 'include' => $ids, 'parent' => 0, ); $categories = get_terms( 'product_cat', $args );

However, now for a given category ID (say 47), I couldn't find the way to get its relevant products. I tried the following way:

$args = array( 'posts_per_page' => 5, 'offset'=> 1, 'category' => 47 ); $products = get_posts( $args ); echo var_dump($products);

Debugging the $products array returns always 0 which is wrong since I know there is some products under the category with ID 47. Any ideas how to fix my code?

我怀疑主要问题是您应该使用WP_Query对象,而不是get_posts().默认情况下,后者仅返回post_type为post的商品,而不返回产品

因此,给定ID为26的类别,以下代码将返回其产品(WooCommerce 3 +):

     $args = array(
    'post_type'             => 'product',
    'post_status'           => 'publish',
    'ignore_sticky_posts'   => 1,
    'posts_per_page'        => '12',
    'tax_query'             => array(
        array(
            'taxonomy'      => 'product_cat',
            'field' => 'term_id', //This is optional, as it defaults to 'term_id'
            'terms'         => 26,
            'operator'      => 'IN' // Possible values are 'IN', 'NOT IN', 'AND'.
        ),
        array(
            'taxonomy'      => 'product_visibility',
            'field'         => 'slug',
            'terms'         => 'exclude-from-catalog', // Possibly 'exclude-from-search' too
            'operator'      => 'NOT IN'
        )
    )
);
$products = new WP_Query($args);
var_dump($products);

在WooCommerce的早期版本中,可见性存储为元字段,因此代码为:

     $args = array(
    'post_type'             => 'product',
    'post_status'           => 'publish',
    'ignore_sticky_posts'   => 1,
    'posts_per_page'        => '12',
    'meta_query'            => array(
        array(
            'key'           => '_visibility',
            'value'         => array('catalog', 'visible'),
            'compare'       => 'IN'
        )
    ),
    'tax_query'             => array(
        array(
            'taxonomy'      => 'product_cat',
            'field' => 'term_id', //This is optional, as it defaults to 'term_id'
            'terms'         => 26,
            'operator'      => 'IN' // Possible values are 'IN', 'NOT IN', 'AND'.
        )
    )
);
$products = new WP_Query($args);
var_dump($products);

在这里,我们仅返回可见的产品,每页12个.

通过 http://codex.wordpress.org/Class_Reference/WP_Query#Taxonomy_Parameters 有关类别定位的工作原理的更多详细信息-通常,按段检索比按ID检索更有用！

I suspect the main problem is that you should be using the WP_Query object rather than get_posts(). The later by default only returns items with a post_type of post not products,

So given a category with ID 26, the following code would return it's products (WooCommerce 3+):

    $args = array(
    'post_type'             => 'product',
    'post_status'           => 'publish',
    'ignore_sticky_posts'   => 1,
    'posts_per_page'        => '12',
    'tax_query'             => array(
        array(
            'taxonomy'      => 'product_cat',
            'field' => 'term_id', //This is optional, as it defaults to 'term_id'
            'terms'         => 26,
            'operator'      => 'IN' // Possible values are 'IN', 'NOT IN', 'AND'.
        ),
        array(
            'taxonomy'      => 'product_visibility',
            'field'         => 'slug',
            'terms'         => 'exclude-from-catalog', // Possibly 'exclude-from-search' too
            'operator'      => 'NOT IN'
        )
    )
);
$products = new WP_Query($args);
var_dump($products);

In earlier versions of WooCommerce the visibility was stored as a meta field, so the code would be:

    $args = array(
    'post_type'             => 'product',
    'post_status'           => 'publish',
    'ignore_sticky_posts'   => 1,
    'posts_per_page'        => '12',
    'meta_query'            => array(
        array(
            'key'           => '_visibility',
            'value'         => array('catalog', 'visible'),
            'compare'       => 'IN'
        )
    ),
    'tax_query'             => array(
        array(
            'taxonomy'      => 'product_cat',
            'field' => 'term_id', //This is optional, as it defaults to 'term_id'
            'terms'         => 26,
            'operator'      => 'IN' // Possible values are 'IN', 'NOT IN', 'AND'.
        )
    )
);
$products = new WP_Query($args);
var_dump($products);

Here we are only returning visible products, 12 per page.

Have a look through http://codex.wordpress.org/Class_Reference/WP_Query#Taxonomy_Parameters for more details about how the category targeting works - it's often more useful to retrieve it by slug than by ID!

解决方案有效.很好的解释.

Solution worked. Nice explanation.

从Woocommerce 3开始,可见性更改为分类而不是meta,因此您需要将meta_query更改为tax_query.参见https://wordpress.stackexchange.com/a/262628/37355.

As of Woocommerce 3, visibility is changed to taxonomy instead of meta so you need to change the meta_query to tax_query. See https://wordpress.stackexchange.com/a/262628/37355.

您对`get_posts()`的结论是错误的.您可以在代码中将`new WP_Query($ args)`替换为`get_posts($ args)`,它将起作用.

Your conclusion about `get_posts()` is wrong. You can replace `new WP_Query($args)` with `get_posts($args)` in your code and it will work.

 $products = wc_get_products(array(
    'category' => array('your-category-slug'),
));

$products = wc_get_products(array(
    'category' => array('your-category-slug'),
));

OP专门要求使用类别ID来获取产品,但是,这对我有所帮助,因此无论如何我都会投票.请注意,它不能回答原始问题

OP specifically asked for getting products using a category ID, however, this helped me, so I'll upvote anyhow. Just be aware it doesn't answer the original question

通过ID或名称或子弹更改类别(类别-子弹名称)

 <?php

$args = array( 'post_type' => 'product', 'stock' => 1, 'posts_per_page' => 2,'product_cat' => 'category-slug-name', 'orderby' =>'date','order' => 'ASC' );
  $loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
global $product; 
?>
Within loop we can fetch Product image, title, description, price etc. 

<?phpendwhile;wp_reset_query(); ?>

change category (category-slug-name) by id or name or slug

<?php

$args = array( 'post_type' => 'product', 'stock' => 1, 'posts_per_page' => 2,'product_cat' => 'category-slug-name', 'orderby' =>'date','order' => 'ASC' );
  $loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
global $product; 
?>
Within loop we can fetch Product image, title, description, price etc. 

<?phpendwhile;wp_reset_query(); ?>

有点晚了,但想澄清一下事情并提供更干净的答案.用户@benz001提供了可能的有效答案,但说错了:get_posts返回任何类型的帖子类型,默认为posts帖子类型,就像WP_Query.很好地解释了这里.

事实是,OP只是在$args数组中缺少一些参数:

他正在搜索的帖子类型的定义:

     'post_type'             => 'product',

以及搜索查询的"分类部分"的修改:

     'tax_query' => array(
        array(
            'taxonomy' => 'product_cat',
            'terms' => 26,
            'operator' => 'IN',
        )
    )

这样您的下一行

 $products = new WP_Query($args);
var_dump($products);

将为您显示所需的产品:)

@benz001显示的所有其他附加参数当然是有效的,但OP并没有要求,因此我决定在此答案中将其保留.

A bit late, but would like to clarify things and provide a cleaner answer. User @benz001 gave a possible valid answer, but said something wrong: get_posts returns any kind of post-types, defaulting to posts post-type, just like WP_Query. The real differences between the two are wonderfully explained HERE.

The fact is, the OP was simply missing some parameters into the $args array:

The definition of the post-type he is searching for:
```
    'post_type'             => 'product',
```

And the modification of the "taxonomy part" of the search query:

    'tax_query' => array(
        array(
            'taxonomy' => 'product_cat',
            'terms' => 26,
            'operator' => 'IN',
        )
    )

This way your next lines

$products = new WP_Query($args);
var_dump($products);

Will show you the needed products :)

All other additional parameters shown by @benz001 are of course valid but not requested by the OP, so I decided to leave them behind in this answer.
