使用自定义简码获取 WooCommerce 特色产品

Question

我试图通过 jquery 滑块获取一系列特色产品以在我自己的插件中使用主题我已经制作了这个功能并从 class-wc-shortcodes.php 获取了属性但没有结果

    add_shortcode('soqopslider', 'wps_soqopslider');
function wps_soqopslider() {

        $atts = shortcode_atts( array(
            'per_page' => '12',
            'columns'  => '4',
            'orderby'  => 'date',
            'order'    => 'desc',
            'category' => '',  // Slugs
            'operator' => 'IN', // Possible values are 'IN', 'NOT IN', 'AND'.
        ), $atts, 'featured_products' );

        $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',
        );


    $query_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,
            );

    // The Query
    $the_query = new WP_Query( query_args );

    // The Loop
    if ( $the_query->have_posts() ) {
        echo '<ul>';
        while ( $the_query->have_posts() ) {
            $the_query->the_post();
            echo '<li>' . get_the_title() . '</li>';
        }
        echo '</ul>';
        /* Restore original Post Data */
        wp_reset_postdata();
    } else {
        echo "No featured products found :(";
    }

    return "<span style='background:green;color:white;' >nothing</span>";

}

我必须添加或更改什么才能使其正常工作我现在将它用作欢迎页面中的简码，仅用于测试

您的代码中存在一些错误。所以我做了必要的修改。

此外，短代码数据必须返回而不是回显。

功能代码如下：

add_shortcode('soqopslider', 'wps_soqopslider');
function wps_soqopslider( $atts) {

    $atts = shortcode_atts(
        array(
            'per_page' => '12',
            'columns'  => '4',
            'orderby'  => 'date',
            'order'    => 'desc',
            'category' => '',  // Slugs
            'operator' => 'IN', // Possible values are 'IN', 'NOT IN', 'AND'.
        ), $atts, 'soqopslider'
    );

    $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',
    );

    $query_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,
    );

    // The Query
    $the_query = new WP_Query( $query_args );

    $html = '</ul>';

    // The Loop
    if ( $the_query->have_posts() ) {
        while ( $the_query->have_posts() ) {
            $the_query->the_post();
            $html .= '<li>' . get_the_title() . '</li>';
        }
        // Restore original Post Data
        wp_reset_postdata();
        // Output
        return $html . '</ul>';
    } else {
        return "No featured products found :(";
    }
}

## BASIC USAGE: [soqopslider]

# ---- #

代码进入您的活动子主题（或主题）的 function.php 文件或任何插件文件。

This code is tested and will output a list of feature products titles.
