我正在创建一个小部件，用于显示我的帖子类型“推荐”中的数据。小部件的后端工作正常，显示了一个推荐列表，并允许我选择要显示在前端的内容。

然而，我的WP\\u查询似乎根本没有引入任何数据。

这是我的小部件前端的代码。

    public function widget( $args, $instance ) {
        // extract the widget arguments
        extract( $args );
        $testimonial = $instance[\'testimonials\'];
        $options = $instance[\'options\'];

        // If All option selected display all testimomials
        if ( $options == \'All\' ) {
        $args = array ( \'post-type\' => \'testimonials\',
                        \'post_status\' => \'publish\',
                        \'posts_per_page\' => 20,
                        \'orderby\' => \'title\',
                        \'order\' => \'ASC\' 
            );
        // else only display the selected testimonial
        } else {
            $args = array( \'post-type\' => \'testimonials\',
                            \'post-status\' => \'publish\',
                            \'post_per_page\' => 20,
                            \'orderby\' => \'title\',
                            \'order\' => \'ASC\',
                            \'post__in\' => $testimonial );
        }

        $my_query = new WP_Query( $args );


?>


    <div id="rotate">
        <!-- WordPress Loop -->
        <?php if ( $my_query->have_posts() ) : while( $my_query->have_posts() ) : $my_query->the_post() ?>
                <p> <!-- echo the testimonial content, trim white space and strip out any unwanted html tags -->
                    "<?php echo trim( strip_tags( get_the_content() ) ); ?>"<br/>
                    <!-- print out the company name -->
                    <span><?php the_title(); ?></span>
                </p>

        <?php endwhile; endif;
        // reset WP query, restores $wp_query and global post data to original main query  
        wp_reset_query(); ?>
    </div>

<?php   }

register_post_type( \'testimonials\',
    array(
        \'labels\' => array(
            \'name\' => __( \'Testimonials\' ),
            \'singular\' => __( \'Testimonial\' ),
            \'add_new_item\' => __( \'Add New Testimonial\' ),
            \'edit_item\' => __( \'Edit Testimonial\' )
