通过woocommerce在模板页面上的自定义循环显示特色产品

我想在home-page.php模板上显示woocommerce商店中的6种特色产品.经过一番研究后,我发现正确的方法是通过自定义循环((我不想使用短代码,因为我想添加其他类来设置样式等.))我还发现woocommerce用于特色产品为" _featured".我将下面的代码放在一起,以显示我选择在商店中成为特色产品的任何产品,但此方法不起作用...不胜感激.

 <?php

    $args = array(
        'post_type'   => 'product',
        'stock'       => 1,
        'showposts'   => 6,
        'orderby'     => 'date',
        'order'       => 'DESC' ,
        'meta_query'  => array(
            array(
                'key'     => '_featured',
                'value'   => 0,
                'compare' => '>',
                'type'    => 'numeric'
            )
        )
    );

    $loop = new WP_Query( $args );
    while ( $loop->have_posts() ) : $loop->the_post(); global $product; ?>

        <li>    
            <?php 
                if ( has_post_thumbnail( $loop->post->ID ) ) 
                    echo get_the_post_thumbnail( $loop->post->ID, 'shop_catalog' ); 
                else 
                    echo '<img src="' . woocommerce_placeholder_img_src() . '" alt="Placeholder" width="65px" height="115px" />'; 
            ?>
            <h3><?php the_title(); ?></h3>

            <?php 
                echo $product->get_price_html(); 
                woocommerce_template_loop_add_to_cart( $loop->post, $product );
            ?>    
        </li>

<?php 
    endwhile;
    wp_reset_query(); 
?>

I would like to display 6 featured products from my woocommerce store on my home-page.php template. After some researched I found that the right way to do this was through a custom loop,( I do not wish to use shortcodes because I would like to add additional classes for styling etc. ) I also found that the key that woocommerce uses for the featured products is '_featured'. I put together the code below to display any products that I chose to be featured products in my store, but it doesn't work... Any help is appreciated.

<?php

    $args = array(
        'post_type'   => 'product',
        'stock'       => 1,
        'showposts'   => 6,
        'orderby'     => 'date',
        'order'       => 'DESC' ,
        'meta_query'  => array(
            array(
                'key'     => '_featured',
                'value'   => 0,
                'compare' => '>',
                'type'    => 'numeric'
            )
        )
    );

    $loop = new WP_Query( $args );
    while ( $loop->have_posts() ) : $loop->the_post(); global $product; ?>

        <li>    
            <?php 
                if ( has_post_thumbnail( $loop->post->ID ) ) 
                    echo get_the_post_thumbnail( $loop->post->ID, 'shop_catalog' ); 
                else 
                    echo '<img src="' . woocommerce_placeholder_img_src() . '" alt="Placeholder" width="65px" height="115px" />'; 
            ?>
            <h3><?php the_title(); ?></h3>

            <?php 
                echo $product->get_price_html(); 
                woocommerce_template_loop_add_to_cart( $loop->post, $product );
            ?>    
        </li>

<?php 
    endwhile;
    wp_reset_query(); 
?>

- 从var_dump(get_meta_values('_featured','product');`中添加结果；其中,get_meta_values函数由[this answer](http://wordpress.stackexchange.com/a/9451/31545)
  
  Add the result from `var_dump( get_meta_values( '_featured', 'product' );` where the function `get_meta_values` is supported by the custom function explained in [this answer](http://wordpress.stackexchange.com/a/9451/31545)

这在WooCommerce 3.0中已更改.它不仅是meta_query,而且现在包括tax_query.现在的参数是:

     $meta_query  = WC()->query->get_meta_query();
    $tax_query   = WC()->query->get_tax_query();
    $tax_query[] = array(
        'taxonomy' => 'product_visibility',
        'field'    => 'name',
        'terms'    => 'featured',
        'operator' => 'IN',
    );

    $args = array(
        'post_type'           => 'product',
        'post_status'         => 'publish',
        'ignore_sticky_posts' => 1,
        'posts_per_page'      => $atts['per_page'],
        'orderby'             => $atts['orderby'],
        'order'               => $atts['order'],
        'meta_query'          => $meta_query,
        'tax_query'           => $tax_query,
    );

请参阅woocommerce/includes/class-wc-shortcodes.php

This has changed in WooCommerce 3.0. It's not simply a meta_query, but now includes a tax_query. The arguments are now:

    $meta_query  = WC()->query->get_meta_query();
    $tax_query   = WC()->query->get_tax_query();
    $tax_query[] = array(
        'taxonomy' => 'product_visibility',
        'field'    => 'name',
        'terms'    => 'featured',
        'operator' => 'IN',
    );

    $args = array(
        'post_type'           => 'product',
        'post_status'         => 'publish',
        'ignore_sticky_posts' => 1,
        'posts_per_page'      => $atts['per_page'],
        'orderby'             => $atts['orderby'],
        'order'               => $atts['order'],
        'meta_query'          => $meta_query,
        'tax_query'           => $tax_query,
    );

See woocommerce/includes/class-wc-shortcodes.php

正是我想要的！

Just what I was looking for!

同样对于Woocommerce 3.0,他们建议使用" wc_placeholder_img_src"而不是" woocommerce_placeholder_img_src".

Also for Woocommerce 3.0, they recommend using `wc_placeholder_img_src` instead of `woocommerce_placeholder_img_src`.

根据 WooCommerce Wiki :

在将来的WooCommerce版本中,随着数据移向自定义表以提高性能,构建自定义WP_Queries或数据库查询(以检索产品)可能会破坏代码.

WooCommerce提倡使用wc_get_products()或WC_Product_Query()而不是WP_Query()或get_posts()

我已经用我用来实现您想要的代码的代码写了一篇文章: https://cfxdesign.com/create-a-custom-woocommerce-product-loop-the-right-way/

According to the WooCommerce Wiki:

Building custom WP_Queries or database queries [to retrieve products] is likely to break your code in future versions of WooCommerce as data moves towards custom tables for better performance.

WooCommerce advocates using wc_get_products() or WC_Product_Query() instead of WP_Query() or get_posts().

我知道这已经很老了,但是我刚刚在此处分享了一个替代解决方案,我认为它可以为您提供帮助那些也达到这个主题的人.

您可以使用 wc_get_featured_product_ids()也是如此:

 $args = array(
    'post_type'           => 'product',
    'posts_per_page'      => 6,
    'orderby'             => 'date',
    'order'               => 'DESC',
    'post__in'            => wc_get_featured_product_ids(),
);

$query = new WP_Query( $args );

希望对您有帮助！

I know this is quite old, but I've just shared an alternative solution here and I think it can help those reaching this topic too.

Instead of using meta_query or tax_query, you can use wc_get_featured_product_ids() too:

$args = array(
    'post_type'           => 'product',
    'posts_per_page'      => 6,
    'orderby'             => 'date',
    'order'               => 'DESC',
    'post__in'            => wc_get_featured_product_ids(),
);

$query = new WP_Query( $args );

I hope it helps!

基于: https://github.com/woocommerce/woocommerce/wiki/wc_get_products-and-WC_Product_Query

我会尝试:

外循环:

 $args = array (
'limit' => 6,
'orderby' => 'title',
'order' => 'ASC',
'category' => $club_cat,
'stock_status' => 'instock',
'featured' => true,

 );

 $products = wc_get_products( $args );

在循环中:

 $query = new WC_Product_Query( array(
'limit' => 6,
'orderby' => 'title',
'order' => 'ASC',
'category' => $club_cat,
'stock_status' => 'instock',
'featured' => true,
'return' => 'ids',

 ) );

 $products = $query->get_products();

Based on: https://github.com/woocommerce/woocommerce/wiki/wc_get_products-and-WC_Product_Query

I would try:

outside loop:

$args = array (
'limit' => 6,
'orderby' => 'title',
'order' => 'ASC',
'category' => $club_cat,
'stock_status' => 'instock',
'featured' => true,

 );

 $products = wc_get_products( $args );

in the loop:

$query = new WC_Product_Query( array(
'limit' => 6,
'orderby' => 'title',
'order' => 'ASC',
'category' => $club_cat,
'stock_status' => 'instock',
'featured' => true,
'return' => 'ids',

 ) );

 $products = $query->get_products();

人们应该开始使用wc_get_products,因为woocommerce表示这是检索产品的标准方法. wc_get_products具有一个仅需设置为true的参数.所以代码就在下面.

  <?php 

// Display featured products by category. on this case its "shirts" which is the slug of the category.
$query_args = array(
    'featured' => true,  
    'category' => array( 'shirts' ),
);
$products = wc_get_products( $query_args );

global $post;
$columns = wc_get_loop_prop( 'columns' );
?>
<div class="woocommerce columns-<?php echo esc_attr( $columns ); ?>">
  <?php
    woocommerce_product_loop_start();
    foreach ($products as $product) {
        $post = get_post($product->get_id());
        setup_postdata($post);
        wc_get_template_part('content', 'product');
    }
    wp_reset_postdata();
    woocommerce_product_loop_end();
  ?>
</div>

在此处查看完整文章: https://jameshwartlopez.com/plugin/get-featured-products-of-a-category/

People should start using wc_get_products because woocommerce said this is the standard way of retrieving product. wc_get_products has an argument featured which just needs to be set to true. So the code is simply below.

 <?php 

// Display featured products by category. on this case its "shirts" which is the slug of the category.
$query_args = array(
    'featured' => true,  
    'category' => array( 'shirts' ),
);
$products = wc_get_products( $query_args );

global $post;
$columns = wc_get_loop_prop( 'columns' );
?>
<div class="woocommerce columns-<?php echo esc_attr( $columns ); ?>">
  <?php
    woocommerce_product_loop_start();
    foreach ($products as $product) {
        $post = get_post($product->get_id());
        setup_postdata($post);
        wc_get_template_part('content', 'product');
    }
    wp_reset_postdata();
    woocommerce_product_loop_end();
  ?>
</div>

如果您查看wp_postmeta表中的数据库,将会看到meta_key将具有_featured和meta_value将是yes或no,因此不是值0或1,而是写yes或no

 <?php
    $q = new WP_Query([
      'post_type'   =>  'product',
      'stock'       =>  1,
      'showposts'   =>  3,
      'orderby'     =>  'date',
      'order'       =>  'DESC',
      'meta_query'  =>  [ 
        ['key' => '_featured', 'value' => 'yes' ]
        ]
    ]);
    if ( $q->have_posts() ) :
        while ( $q->have_posts() ) : $q->the_post();
            // display product info
        endwhile; wp_reset_query();
    endif;
?>

if you take a look in the database in wp_postmeta table you will see meta_key will be _featured and meta_value will be yes or no so instead of value 0 or 1 write yes or no

<?php
    $q = new WP_Query([
      'post_type'   =>  'product',
      'stock'       =>  1,
      'showposts'   =>  3,
      'orderby'     =>  'date',
      'order'       =>  'DESC',
      'meta_query'  =>  [ 
        ['key' => '_featured', 'value' => 'yes' ]
        ]
    ]);
    if ( $q->have_posts() ) :
        while ( $q->have_posts() ) : $q->the_post();
            // display product info
        endwhile; wp_reset_query();
    endif;
?>

将您的参数更改为这样:

 $meta_query   = WC()->query->get_meta_query();
$meta_query[] = array(
    'key'   => '_featured',
    'value' => 'yes'
);
$args = array(
    'post_type'   =>  'product',
    'stock'       =>  1,
    'showposts'   =>  6,
    'orderby'     =>  'date',
    'order'       =>  'DESC',
    'meta_query'  =>  $meta_query
);

如果您访问wp-content/plugins/woocommerce/includes/class-wc-shortcodes.php(@ 595),则可以找到WC短代码的处理方法.

Change your args to be like this:

$meta_query   = WC()->query->get_meta_query();
$meta_query[] = array(
    'key'   => '_featured',
    'value' => 'yes'
);
$args = array(
    'post_type'   =>  'product',
    'stock'       =>  1,
    'showposts'   =>  6,
    'orderby'     =>  'date',
    'order'       =>  'DESC',
    'meta_query'  =>  $meta_query
);

If you go to wp-content/plugins/woocommerce/includes/class-wc-shortcodes.php (@595) you can find how it's done for WC shortcodes.

他们要注意的关键是" _featured"未存储为数值.它存储为字符串"是"或"否".OP问题中的其他所有内容都应该对我有用.

They key to note is that '_featured' is not stored as a numeric value. It is stored as a string 'yes' or 'no'. Everything else in the OP question should work, worked for me.
