我编写了一个简单的插件来创建一个名为“people”的自定义帖子类型：

add_action( \'init\', \'create_person\' );

function create_person() {
    register_post_type( \'people\',
        array(
            \'labels\' => array(
                \'name\' => \'People\',
                \'singular_name\' => \'Person\',
                \'add_new\' => \'Add New\',
                \'add_new_item\' => \'Add New Person\',
                \'edit\' => \'Edit\',
                \'edit_item\' => \'Edit Person\',
                \'new_item\' => \'New Person\',
                \'view\' => \'View\',
                \'view_item\' => \'View Person\',
                \'search_items\' => \'Search People\',
                \'not_found\' => \'No person found\',
                \'not_found_in_trash\' => \'No people found in trash\',
                \'parent\' => \'Parent Person\'
            ),

            \'public\' => true,
            \'menu_position\' => null,
            \'supports\' => array( \'title\', \'editor\', \'comments\', \'thumbnail\', \'custom-fields\' ),
            \'taxonomies\' => array( \'\' ),
            \'menu_icon\' => plugins_url( \'images/people_icon.png\', __FILE__ ),
            \'publicly_queryable\' => true,
            \'show_ui\' => true, 
            \'show_in_menu\' => true, 
            \'query_var\' => true,
            \'rewrite\' => array( \'slug\' => \'people\',\'with_front\' => FALSE),
            \'capability_type\' => \'post\',
            \'hierarchical\' => false,
            \'has_archive\' => true
        )
    );
}

并添加了一个名为“单人”的模板。php显示自定义帖子类型。此筛选器与上面的代码位于同一文件中：

add_filter( \'template_include\', \'include_template_people\', 1 );

function include_template_people( $template_path ) {
    if ( get_post_type() == \'people\' ) {
        if ( is_single() ) {
            // checks if the file exists in the theme first,
            // otherwise serve the file from the plugin
            if ( $theme_file = locate_template( array ( \'single-people.php\' ) ) ) {
                $template_path = $theme_file;
            } else {
                $template_path = plugin_dir_path( __FILE__ ) . \'/single-people.php\';
            }
        }
    }
    return $template_path;
}

然后这里有实际的模板：

<?php
 /*Template Name: New Template
 */

get_header(); ?>
<div id="primary">

    <div id="content" role="main">
    <?php
    $mypost = array( \'post_type\' => \'people\', );
    $loop = new WP_Query( $mypost );
    ?>
    <?php while ( $loop->have_posts() ) : $loop->the_post();?>
        <article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
            <div class="person">
                <div class="person-header">
                    <div class="person-image">
                        <?php the_post_thumbnail( array( 300, 300 ) ); ?>
                    </div>
                    <div class="person-name"><?php the_title(); ?></div>
                    <div class="roles-list">
                        <?php echo get_the_term_list( $id, \'roles\', \'\', \', \', \'\' ); ?>
                    </div>
                </div>
                <div class="person-content"><?php the_content(); ?></div>
            </div>
        </article>

    <?php endwhile; ?>
    </div>
</div>
<?php wp_reset_query(); ?>
<?php get_footer(); ?>

更新日期：

我把问题改了一点。我删除了我添加的一段代码。这个模板的问题是，当我转到URL时：

mysite.com/people/firstname-lastname

我希望只得到“people”类型的帖子，上面有“firstname lastname”。相反，所有类型为“people”的帖子都会显示在页面上。如何更改此设置，以便仅显示单个“帖子”？

<?php get_header(); ?>
<div id="primary">
<div id="content" role="main">
<?php if ( have_posts() ) : the_post(); ?>
    <article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
        <div class="person">
            <div class="person-header">
                <div class="person-image">
                    <?php the_post_thumbnail( array( 300, 300 ) ); ?>
                </div>
                <div class="person-name"><?php the_title(); ?></div>
                <div class="roles-list">
                    <?php echo get_the_term_list( get_the_ID(), \'roles\', \'\', \', \', \'\' ); ?>
                </div>
            </div>
            <div class="person-content"><?php the_content(); ?></div>
        </div>
    </article>
<?php endif; ?>
</div>
</div>
<?php get_footer(); ?>
