问题是，我试图用一个“got to this Portfolio”按钮，只在拇指中显示文章的拇指和标题。类似这样：

    <section>
        <div class="portfolio">
            <div class="row">
            <?php
                $args = array( \'post_type\' => \'portfolio\', \'posts_per_page\' => 10 );
                $loop = new WP_Query( $args );
                while ( $loop->have_posts() ) : $loop->the_post();
                    echo \'<div class="col-md-4">\';
                    echo \'<h4>\';
                    the_title();
                    echo \'</h4>\';
                    // The Thumb
                    echo \'</div>\';
                endwhile;
            ?>
            </div>
        </div>
    </section>

WordPress管理面板中没有显示对自定义类型的thumb支持的另一件事是函数。php代码：

    /* Custom Post Type Start */

    function create_posttype() {
    register_post_type( \'portfolio\',
    // CPT Options

    array(
        \'labels\' => array(
        \'name\' => __( \'portfolio\' ),
        \'singular_name\' => __( \'portfolio\' )
        ),
        \'public\' => true,
        \'has_archive\' => false,
        \'rewrite\' => array(\'slug\' => \'portfolio\'),
    )
    );
    }
        // Hooking up our function to theme setup
    add_action( \'init\', \'create_posttype\' );

    /* Custom Post Type End */

    /*Custom Post type start*/

function cw_post_type_portfolio() {

    $supports = array(
    \'title\', // post title
    \'editor\', // post content
    \'author\', // post author
    \'thumbnail\', // featured images
    \'excerpt\', // post excerpt
    \'custom-fields\', // custom fields
    \'comments\', // post comments
    \'revisions\', // post revisions
    \'post-formats\', // post formats
    );

    $labels = array(
    \'name\' => _x(\'portfolio\', \'plural\'),
    \'singular_name\' => _x(\'portfolio\', \'singular\'),
    \'menu_name\' => _x(\'portfolio\', \'admin menu\'),
    \'name_admin_bar\' => _x(\'portfolio\', \'admin bar\'),
    \'add_new\' => _x(\'Add New\', \'add new\'),
    \'add_new_item\' => __(\'Add New portfolio\'),
    \'new_item\' => __(\'New portfolio\'),
    \'edit_item\' => __(\'Edit portfolio\'),
    \'view_item\' => __(\'View portfolio\'),
    \'all_items\' => __(\'All portfolio\'),
    \'search_items\' => __(\'Search portfolio\'),
    \'not_found\' => __(\'No portfolio found.\'),
    );

    $args = array(
    \'supports\' => array( \'title\', \'editor\', \'author\', \'thumbnail\', \'excerpt\', \'comments\' ),
    \'labels\' => $labels,
    \'public\' => true,
    \'query_var\' => true,
    \'rewrite\' => array(\'slug\' => \'portfolio\'),
    \'has_archive\' => true,
    \'hierarchical\' => false,
    );
    register_post_type(\'portfolio\', $args);
    }
    add_action(\'init\', \'cw_post_type_portfolio\');

    /*Custom Post type end*/
