Question

我尝试使用jquery滑块在我自己的插件中使用主题的一系列特色产品我已经完成了这个功能，并从class-wc-shortcodes.php获得了attrs 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>";

}

我必须添加或更改以使其有效我现在将它用作欢迎页面中的短代码，仅用于测试

您的代码中存在一些错误。所以我有佣人必要的改变。

还必须返回短代码数据而不回显。

以下是功能代码：

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]

# ---- #

代码放在活动子主题（或主题）的function.php文件中，或者放在任何插件文件中。

此代码经过测试，将输出功能产品标题列表。
