我的循環顯示精選帖子,然後按倒序時間順序發佈帖子。如何過濾通過元值DESC和發佈日期DESC獲得之前的帖子功能?

但是,當我使用<?php echo get_previous_post(); ?>時,它會以反向時間順序抓取帖子。

如何添加一個過濾器到類似於this類似的以前的帖子功能,而是過濾一個像這樣的數組:'orderby' => array('meta_value' => 'DESC', 'date' => 'DESC')


代碼:


UPDATE:

盪滌的index.php從@sMyles幫助和@JackJohansson

的index.php後循環迴路

$args = array( 'posts_per_page' => - 1, 'meta_key' => 'meta-checkbox', 'orderby' => array('meta_value' => 'DESC', 'date' => 'DESC') ); $posts = new WP_Query($args); if($posts->have_posts()){ while($posts->have_posts()){ $posts->the_post(); // Set to content template by default $template = 'content'; // Change template to featured when `is_featured` meta has a value if(get_post_meta(get_the_ID(), 'meta-checkbox', 'yes')){ $template = 'featured'; } // Load template part get_template_part($template, get_post_format()); } } 


UPDATE:至於建議,我說,我用以前的帖子功能

一篇文章功能

<div id="next-post"> 
    <?php $prev_post = get_previous_post(); 
    if(!empty($prev_post)) { 
     echo '<a class="next-story" href="' . get_permalink($prev_post->ID) . '">Next Story</a>'; 
     echo '<a class="next-story-title" href="' . get_permalink($prev_post->ID) . '" title="' . $prev_post->post_title . '">' . $prev_post->post_title . '</a>'; 
    } ?> 
</div> 


功能對於精選文章:

function sm_custom_meta() { 
    add_meta_box('sm_meta', __('Featured Posts', 'sm-textdomain'), 'sm_meta_callback', 'post'); 
} 
function sm_meta_callback($post) { 
    $featured = get_post_meta($post->ID); 
?> 

<p> 
<div class="sm-row-content"> 
    <label for="meta-checkbox"> 
     <input type="checkbox" name="meta-checkbox" id="meta-checkbox" value="yes" <?php if (isset ($featured['meta-checkbox'])) checked($featured['meta-checkbox'][0], 'yes'); ?> /> 
     <?php _e('Featured this post', 'sm-textdomain')?> 
    </label> 

</div> 
</p> 

<?php 
} 
add_action('add_meta_boxes', 'sm_custom_meta'); 

function sm_meta_save($post_id) { 

    // Checks save status 
    $is_autosave = wp_is_post_autosave($post_id); 
    $is_revision = wp_is_post_revision($post_id); 
    $is_valid_nonce = (isset($_POST[ 'sm_nonce' ]) && wp_verify_nonce($_POST[ 'sm_nonce' ], basename(__FILE__))) ? 'true' : 'false'; 

    // Exits script depending on save status 
    if ($is_autosave || $is_revision || !$is_valid_nonce) { 
     return; 
    } 

    // Checks for input and saves 
    if(isset($_POST[ 'meta-checkbox' ])) { 
     update_post_meta($post_id, 'meta-checkbox', 'yes'); 

    } else { 
     update_post_meta($post_id, 'meta-checkbox', ''); 
    } 

} 
add_action('save_post', 'sm_meta_save');

請嘗試以下參數

$args = array(
     'meta_key' => 'meta-checkbox', 
     'meta_value' => 'yes', 
     'posts_per_page' => -1, 
     'order_by'=> 'meta_value', 
     'order'=>'ASC' 
    );
