Wordpress - 创建一个短代码来列出帖子

Question

I have created the custom post. I want to list down posts, but my shortcodes are not working.

Here is my code

function.php

// register a custom post type called 'Products'

function wptp_create_post_type() {
    $labels = array(
        'name' => __( 'Products' ),
        'singular_name' => __( 'product' ),
        'add_new' => __( 'New product' ),
        'add_new_item' => __( 'Add New product' ),
        'edit_item' => __( 'Edit product' ),
        'new_item' => __( 'New product' ),
        'view_item' => __( 'View product' ),
        'search_items' => __( 'Search products' ),
        'not_found' =>  __( 'No product Found' ),
        'not_found_in_trash' => __( 'No product found in Trash' ),
    );
    $args = array(
        'labels' => $labels,
        'has_archive' => true,
        'public' => true,
        'hierarchical' => false,
        'supports' => array(
            'title',
            'editor',
            'excerpt',
            'custom-fields',
            'thumbnail',
            'page-attributes'
        ),
        'taxonomies' => array( 'post_tag', 'category' ),
    );
    register_post_type('product', $args );
}
add_action( 'init', 'wptp_create_post_type' );

product-page.php

add_shortcode( 'list-posts', 'rmcc_post_listing_parameters_shortcode' );
function rmcc_post_listing_parameters_shortcode( $atts ) {
    ob_start();
    extract( shortcode_atts( array (
        'type' => 'product',
        'order' => 'date',
        'orderby' => 'title',
        'posts' => -1,

        'category' => '',
    ), $atts ) );
    $options = array(
        'post_type' => $type,
        'order' => $order,
        'orderby' => $orderby,
        'posts_per_page' => $posts,

        'category_name' => $category,
    );
    $query = new WP_Query( $options );
    if ( $query->have_posts() ) { ?>

            <?php while ( $query->have_posts() ) : $query->the_post(); ?>
            <li id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
                <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
            </li>
            <?php endwhile;
            wp_reset_postdata(); ?>
        </ul>
    <?php $myvariable = ob_get_clean();
    return $myvariable;
    }   
}

I have created a page from dashboard and select product-page as template and when I preview or load the page, but I couldn't see my posts.

I have try these below shortcodes on my page. Nothing works out for me

[list-posts]

[list-posts type="products" category = "movies" orderby="name" order="ASC"]

I followed this tutorial

add_shortcode( 'list-posts', 'rmcc_post_listing_parameters_shortcode' );
function rmcc_post_listing_parameters_shortcode( $atts ) {
    ob_start();
    extract( shortcode_atts( array (

    $options = array(

            'order' => $order,
            'orderby' => $orderby,
            'posts_per_page' => $posts,

            'category_name' => $category,
    );
    $query = new WP_Query( $options );
    if ( $query->have_posts() ) { ?>

            <?php while ( $query->have_posts() ) : $query->the_post(); ?>

        </ul>
    <?php $myvariable = ob_get_clean();
    return $myvariable;
    }

?>

product-page.php

 echo do_shortcode('[list-posts]');

I think that would help you. Let me know if you want something else
