我需要一些帮助，以获得一个横幅图像分配给一个页面自定义帖子类型。每页只有一个图像，每页都有不同的横幅图像，只需在img 标签

我在我的函数中尝试过这个。php：

function sixohthree_init() {
    $labels = array(
        \'name\' => \'Header Images\',
        \'singular_name\' => \'Header Image\',
        \'add_new_item\' => \'Add Header Image\',
        \'edit_item\' => \'Edit Header Image\',
        \'new_item\' => \'New Header Image\',
        \'view_item\' => \'View Header Image\',
        \'search_items\' => \'Search Header Images\',
        \'not_found\' => \'No Header Images found\',
        \'not_found_in_trash\' => \'No Header Images found in Trash\'
    );

    $args = array(
        \'labels\' => $labels,
        \'public\' => false,
        \'show_ui\' => true,
        \'supports\' => array(\'thumbnail\')
    );

    register_post_type( \'header-image\', $args );
}
add_action( \'init\', \'sixohthree_init\' );

/**
 * Modify which columns display when the admin views a list of header-image posts.
 */
function sixohthree_headerimage_posts_columns( $posts_columns ) {
    $tmp = array();

    foreach( $posts_columns as $key => $value ) {
        if( $key == \'title\' ) {
            $tmp[\'header-image\'] = \'Header Image\';
        } else {
            $tmp[$key] = $value;
        }
    }

    return $tmp;
}
add_filter( \'manage_header-image_posts_columns\', \'sixohthree_headerimage_posts_columns\' );

/**
 * Custom column output when admin is view the header-image post list.
 */
function sixohthree_headerimage_custom_column( $column_name ) {
    global $post;

    if( $column_name == \'header-image\' ) {
        echo "<a href=\'", get_edit_post_link( $post->ID ), "\'>", get_the_post_thumbnail( $post->ID ), "</a>";
    }
}
add_action( \'manage_posts_custom_column\', \'sixohthree_headerimage_custom_column\' );

/**
 * Make the "Featured Image" metabox front and center when editing a header-image post.
 */
function sixohthree_headerimage_metaboxes( $post ) {
    global $wp_meta_boxes;

    remove_meta_box(\'postimagediv\', \'header-image\', \'side\');
    add_meta_box(\'postimagediv\', __(\'Featured Image\'), \'post_thumbnail_meta_box\', \'header-image\', \'normal\', \'high\');
}
add_action( \'add_meta_boxes_header-image\', \'sixohthree_headerimage_metaboxes\' );

/**
 * Enable thumbnail support in the theme, and set the thumbnail size.
 */
function sixohthree_after_setup() {
    add_theme_support( \'post-thumbnails\' );
    set_post_thumbnail_size(150, 100, true);
}
add_action( \'after_setup_theme\', \'sixohthree_after_setup\' );
