通过WooCommerce按类别显示所有产品

我希望使用WooCommerce将商店中的所有类别显示为标题,并且其所有产品下面都以无序列表的形式列出.这可能吗?我看过几件事,可以显示类别列表或特定类别的产品列表,但没有任何内容可以像我描述的那样循环显示所有内容.

这是我目前用来列出所有类别的内容:

 <?php
$args = array(
    'number'     => $number,
    'orderby'    => $orderby,
    'order'      => $order,
    'hide_empty' => $hide_empty,
    'include'    => $ids
);
$product_categories = get_terms( 'product_cat', $args );
$count = count($product_categories);
if ( $count > 0 ){
    foreach ( $product_categories as $product_category ) {
        echo '<h4><a href="' . get_term_link( $product_category ) . '">' . $product_category->name . '</h4>';
    }
}
?>

With WooCommerce, I want to display all the categories in a store as headings, with all of their products listed below in an unordered list. Is this possible to do? I've seen a few things that'll let me display a list of categories or a list of products for a specific category, but nothing that'll loop through everything the way I described.

Here's what I'm currently using to list all categories:

<?php
$args = array(
    'number'     => $number,
    'orderby'    => $orderby,
    'order'      => $order,
    'hide_empty' => $hide_empty,
    'include'    => $ids
);
$product_categories = get_terms( 'product_cat', $args );
$count = count($product_categories);
if ( $count > 0 ){
    foreach ( $product_categories as $product_category ) {
        echo '<h4><a href="' . get_term_link( $product_category ) . '">' . $product_category->name . '</h4>';
    }
}
?>

- 您只需要一个循环.在您的`foreach()`中,运行一个新的`WP_Query()`来获取该术语中的所有产品.然后遍历这些产品.
  
  You simply need a loop of loops. Inside your `foreach()`, run a new `WP_Query()` to grab all the products in that term.. and then loop through those.

- 我想我知道如何做到这一点,但是我找不到关于使用PHP按类别列出产品的任何信息(我所能找到的只是短代码废话).如果您可以告诉我该代码是什么样的,那么我应该可以弄清楚其余的代码.
  
  I think I understand how to do this, but I can't find anything about listing products by category with PHP (all I can find is shortcode nonsense). If you can show me what that code looks like, I should be able to figure out the rest.

- 您不需要简码,按类别列出产品只是[税收查询](http://codex.wordpress.org/Class_Reference/WP_Query#Taxonomy_Parameters).
  
  You don't need a shortcode, listing products by category is just a [Tax Query](http://codex.wordpress.org/Class_Reference/WP_Query#Taxonomy_Parameters).

- 我知道我不需要简码,我只是说那是我能找到的,这无济于事.您提供的链接看起来很有希望,我明天会试一试,然后报告,谢谢.
  
  I knew I didn't need a shortcode, I was saying that's all I could find, which was unhelpful. That link you provided looks promising, I'll give it a shot tomorrow and report back, thanks.

- 好.如果您仍然遇到问题,请尝试使用新的编码方法来编辑问题,我会看一下.
  
  Ok. If you are still stuck, edit your question with your new coding attempt and I'll take a look.

想通了！下面的代码会自动列出所有类别以及每个类别的帖子！

 $args = array(
    'number'     => $number,
    'orderby'    => 'title',
    'order'      => 'ASC',
    'hide_empty' => $hide_empty,
    'include'    => $ids
);
$product_categories = get_terms( 'product_cat', $args );
$count = count($product_categories);
if ( $count > 0 ){
    foreach ( $product_categories as $product_category ) {
        echo '<h4><a href="' . get_term_link( $product_category ) . '">' . $product_category->name . '</a></h4>';
        $args = array(
            'posts_per_page' => -1,
            'tax_query' => array(
                'relation' => 'AND',
                array(
                    'taxonomy' => 'product_cat',
                    'field' => 'slug',
                    // 'terms' => 'white-wines'
                    'terms' => $product_category->slug
                )
            ),
            'post_type' => 'product',
            'orderby' => 'title,'
        );
        $products = new WP_Query( $args );
        echo "<ul>";
        while ( $products->have_posts() ) {
            $products->the_post();
            ?>
                <li>
                    <a href="<?php the_permalink(); ?>">
                        <?php the_title(); ?>
                    </a>
                </li>
            <?php
        }
        echo "</ul>";
    }
}

Figured it out! The code below automatically lists all categories and each categories posts!

$args = array(
    'number'     => $number,
    'orderby'    => 'title',
    'order'      => 'ASC',
    'hide_empty' => $hide_empty,
    'include'    => $ids
);
$product_categories = get_terms( 'product_cat', $args );
$count = count($product_categories);
if ( $count > 0 ){
    foreach ( $product_categories as $product_category ) {
        echo '<h4><a href="' . get_term_link( $product_category ) . '">' . $product_category->name . '</a></h4>';
        $args = array(
            'posts_per_page' => -1,
            'tax_query' => array(
                'relation' => 'AND',
                array(
                    'taxonomy' => 'product_cat',
                    'field' => 'slug',
                    // 'terms' => 'white-wines'
                    'terms' => $product_category->slug
                )
            ),
            'post_type' => 'product',
            'orderby' => 'title,'
        );
        $products = new WP_Query( $args );
        echo "<ul>";
        while ( $products->have_posts() ) {
            $products->the_post();
            ?>
                <li>
                    <a href="<?php the_permalink(); ?>">
                        <?php the_title(); ?>
                    </a>
                </li>
            <?php
        }
        echo "</ul>";
    }
}

真好如果您想变得非常疯狂,则可能需要研究[Transients API](https://codex.wordpress.org/Transients_API)...,这将有助于您避免在每次加载页面时都运行这么多查询.

Nice. If you want to get really crazy you might want to look into the [Transients API](https://codex.wordpress.org/Transients_API)... that would help keep you from running so many queries on every page load.

如何获得每个类别的图像缩略图?

How can I get the image thumbnails for each category?

@AlyssaReyes类别本质上没有缩略图.您是否为此为此类别设置了自定义字段?您可以将其发布在新问题中,并提供更多详细信息,并将链接发送给我,以便我更好地理解吗?

@AlyssaReyes categories don't inherently have thumbnails; did you set up a custom field for your categories for this? Could you post this in a new question with more detail and send me the link so I can better understand?

谢谢您,您为我节省了一些时间,并设定了正确的方向.我可以改善此答案的唯一方法是使用WooCommerce的内置查询类:WC_Product_Query而不是WP_Query,然后使用foreach循环而不是while循环.由于某些原因,请查看Github查询文档:https://github.com/woocommerce/woocommerce/wiki/wc_get_products-and-WC_Product_Query#description,但是要点是:>"自定义WP_Queries查询可能会随着数据移向自定义表以提高性能,在将来的WooCommerce版本中破坏代码."

Thanks man, you saved me some time and set me in the right direction. The only way I could improve this answer is to use WooCommerce's built-in query class: `WC_Product_Query`, instead of `WP_Query`, then use a `foreach` loop instead of a `while` loop. For reasons why, take a look at the Github documentation for the query: https://github.com/woocommerce/woocommerce/wiki/wc_get_products-and-WC_Product_Query#description, but the gist is: > "custom WP_Queries queries is likely to break your code in future versions of WooCommerce as data moves towards custom tables for better performance."
