Wordpress上的精选帖子部分不会显示

[英]Featured Posts Section on Wordpress won't show up

尝试在我的网站上创建“特色帖子”部分,其中涉及三个文件:

  • 头文件
  • 页脚文件
  • 功能文件
  • 索引文件

我想通过选择编辑屏幕(帖子页面)中的复选框来选择特色帖子,并能够在首页上检索这些特色文章。

到目前为止,使用我当前的代码,它仅在帖子页面编辑屏幕上显示一个复选框,但是不会保存,并且在首页上除了帖子循环外什么都没有出现。

这是我的functions.php文件:

/**
 * ----------------------------------------------------------------------------------------
 * 1.0 - Define constants.
 * ----------------------------------------------------------------------------------------
 */

define( 'THEMEROOT', get_stylesheet_directory_uri() );
define( 'IMAGES', THEMEROOT. '/images' );
define( 'SCRIPTS', THEMEROOT. '/js' );

/** */


/***********************************************************************************************/
/* 2.0 - Add Theme Support for Post Thumbnails */
/***********************************************************************************************/
if (function_exists('add_theme_support')) {
    add_theme_support('post-thumbnails');
    set_post_thumbnail_size(300, 200);

}



/***********************************************************************************************/
/* 3.0 - Add Theme Support for Post Thumbnails */
/***********************************************************************************************/


function register_post_assets(){
    add_meta_box('featured-post', __('Featured Post'), 'add_featured_meta_box', 'post', 'advanced', 'high');
}
add_action('admin_init', 'register_post_assets', 1);

function add_featured_meta_box($post){
    $featured = get_post_meta($post->ID, '_featured-post', true);
    echo "<label for='_featured-post'>".__('Feature this post?', 'foobar')."</label>";
    echo "<input type='checkbox' name='_featured-post' id='featured-post' value='1' ".checked(1, $featured)." />";
}

function save_featured_meta($post_id){
    // Do validation here for post_type, nonces, autosave, etc...
    if (isset($_REQUEST['featured-post']))
        update_post_meta(esc_attr($post_id, '_featured-post', esc_attr($_REQUEST['featured-post']))); 
        // I like using _ before my custom fields, so they are only editable within my form rather than the normal custom fields UI
}
add_action('save_post', 'save_featured_meta');


?>

这是我在index.php文件上的代码:

<?php get_header(); ?>
<?php while(have_posts()) : the_post(); ?>
          <h1><a href="<?php the_permalink(); ?>" class="gray">
            <?php the_title(); ?>
            </a></h1>
          <p class="details">By <a href="<?php the_author_posts() ?>"><?php the_author(); ?> </a> / On <?php echo get_the_date('F j, Y'); ?> / In <?php the_category(', '); ?></p>
          <?php if (has_post_thumbnail()) : ?>
          <figure> <a href="<?php the_permalink(); ?>"><?php the_post_thumbnail('', array('class' => 'opacity-hover box-layer img-responsive')); ?></a> </figure>
          <p class="excerpt"> <?php the_excerpt(); ?> </p>
          <div class="btn-margin"> <a href="<?php the_permalink(); ?>" class="btn btn-primary">CONTINUE READING >>> </a> </div>
        </li>
        <?php endif; ?>
        <?php endwhile; ?>


<h1>Featured Posts</h1>     
<?php       
  $args = array(
        'posts_per_page' => 5,
        'meta_key' => '_featured-post',
        'meta_value' => 1
    );

    $featured = new WP_Query($args);

    if ($featured->have_posts()): while($featured->have_posts()): $featured->the_post();
        the_title();
        the_content();
    endwhile; else:

    endif;  
?>      

<?php get_footer(); ?>

您知道导致问题的原因是什么,或者如果我缺少什么? 我只想在我的博客上至少有一个特色帖子部分类似于此图片:

有什么帮助吗?

function add_featured_meta_box($post){
    $featured = get_post_meta($post->ID, '_featured-post', true);
    echo "<label for='_featured-post'>".__('Feature this post?', 'foobar')."</label>";
    echo "<input type='checkbox' name='featured-post' id='featured-post' value='1' ".checked(1, $featured)." />";
}

function save_featured_meta($post_id){
    // Do validation here for post_type, nonces, autosave, etc...
    if (isset($_REQUEST['featured-post']))
        update_post_meta(esc_attr($post_id), '_featured-post', esc_attr($_REQUEST['featured-post'])); 
        // I like using _ before my custom fields, so they are only editable within my form rather than the normal custom fields UI
}
add_action('save_post', 'save_featured_meta');

尝试使用该代码,我更正了name属性和update_post_meta函数。 抱歉,但我目前没有安装Wordpress来尝试。

您似乎也两次使用了id featured-post 您应该更改înput字段的ID。
