獲取後反對票特定的自定義字段值

Question

我想後誰擁有自定義字段值「說唱」對自定義文本字段「音樂型」

$artists = array('posts_per_page' => 50, 'offset'=> 0, 'meta_key' => 'music-type', 'meta_value' => 'Rap', 'order'=>'ASC'); 
$artists_lst = get_posts($artists); foreach ($artists_lst as $post) : setup_postdata($post); 
$post_id=$post->ID; 
<li><a href="#"><?php echo $post_id; ?></a></li> 
<?php endforeach; ?> 
</ul> 

Answer 1

解決了問題，使用get_pages而不是get_posts。

Answer 2

每https://codex.wordpress.org/Function_Reference/get_post_custom_values我會嘗試：

$artists = array('posts_per_page' => 50, 'offset'=> 0, 'meta_key' => 'music-type', 'meta_value' => 'Rap', 'order'=>'ASC'); 
$artists_lst = get_posts($artists); 
foreach ($artists_lst as $post) : 
    setup_postdata($post); 
    $post_id=$post->ID; 
    if(get_post_custom_values('music-type', $post_id) == "Rap"):?> 
    <li><a href="#"><?php echo $post_id; ?></a></li> 
    <?php endif; 
endforeach; ?> 

函數info頁面報告它返回一個數組，所以你可能需要在比較之前將它推入一個變量。像：

$music_type = get_post_custom_values('music-type', $post_id); 
if($music_type[0] == "Rap"):?> 

希望有所幫助。
