WooCommerce简码产品列表 [英] WooCommerce shortcode products list

问题描述

我必须制作一个Wordpress插件，该插件添加WooCommerce的简码.我想从特定的产品类别中获取产品，并显示最大数量的产品.简码参数应为类别ID和产品限制.我认为我必须使用WP_Query对象.

I have to make a Wordpress plugin which adds shortcode for WooCommerce. I want to get products from a specific product category and the maximum number of products to show. The shortcode parameters should be category ID and product limit. I think I should have to use WP_Query object.

我需要使它看起来像这样:

I need to get it look like this:

短代码如下:[productslist_category="[category_ID]" limit="[product_limit]"]

我使用了下面的代码 LoicTheAztec ):

I used the code below from this answer (thanks to LoicTheAztec):

if( !function_exists('products_list_in_a_product_category') ) {

function products_list_in_a_product_category( $atts ) {

    // Shortcode Attributes
    $atts = shortcode_atts(
        array(
            'cat'       => '',
            'limit'     => '4', // default product per page
            'column'    => '4', // default columns
        ),
        $atts, 'productslist'
    );

    // The query
    $posts = get_posts( array(
        'post_type'      => 'product',
        'posts_per_page' => intval($atts['limit'])+1,
        'product_cat'    => $atts['cat'],
    ) );

    $output = '<div class="products-in-'.$atts['cat'].'">';

    // The loop
    foreach($posts as $post_obj)
        $ids_array[] = $post_obj->ID;

    $ids = implode( ',', $ids_array );

    $columns = $atts['column'];

    $output .= do_shortcode ( "[products ids=$ids columns=$columns ]" ) . '</div>';

    return $output;
}
add_shortcode( 'productslist', 'products_list_in_a_product_category' );}

但是我得到一个错误.内爆功能出现问题.

But I get an error. It says that there is something wrong with the implode function.

推荐答案

这是我原来的答案，是您删除的上一个问题的缩写，您在此处使用的是: 该代码在woocommerce 2.6.x和3+版本中均可完美运行.

这是您(在删除上一个问题之前)采用的原始答案代码:

这是一个基于您的简码与现有的[product] WooCommerce简码混合的解决方案.如您所见，您将得到您所期望的……

Here is a solution based on your shortcode mixed with existing [product] WooCommerce shortcode. As you will see you will get what you are expecting…

这是代码:

if( !function_exists('products_list_in_a_product_category') ) {

    function products_list_in_a_product_category( $atts ) {

        // Shortcode Attributes
        $atts = shortcode_atts(
            array(
                'cat'       => '',
                'limit'     => '5', // default product per page
                'column'    => '4', // default columns
            ),
            $atts, 'productslist'
        );

        // The query
        $posts = get_posts( array(
            'post_type'      => 'product',
            'posts_per_page' => intval($atts['limit'])+1,
            'product_cat'    => $atts['cat'],
        ) );

        $output = '<div class="products-in-'.$atts['cat'].'">';

        // The loop
        foreach($posts as $post_obj)
            $ids_array[] = $post_obj->ID;

        $ids = implode( ',', $ids_array );

        $columns = $atts['column'];

        $output .= do_shortcode ( "[products ids=$ids columns=$columns ]" ) . '</div>';

        return $output;
    }
    add_shortcode( 'productslist', 'products_list_in_a_product_category' );
}

代码会出现在您活动的子主题(或主题)的function.php文件或任何插件文件中.

此代码已在WooCommerce 3+上经过测试，并且可以正常工作.

This code is tested on WooCommerce 3+ and works.

用法 (示例):

[productslist cat="clothing" limit="4"]

您会得到这个:
