按照顺序在wordpress上显示自定义字段

Question

我在这里有一个情况，我得到的数组自定义字段不正确。我可以知道如何让所有自定义字段顺序吗？

，我用它来获取自定义阵列功能是：

$title = get_post_meta($post_id, "cap-display_name", false); 
foreach($title as $a){ 
    echo 'hello '.$a.'<br><br>'; 
} 

但是，我得到的输出是：

hello this is first 

hello this is second 

hello this is third 

hello this is six 

hello this is four 

hello this is five 

hello this is seven 

假想的输出是：

hello this is first 

hello this is second 

hello this is third 

hello this is four 

hello this is five 

hello this is six 

hello this is seven 

我可以知道如何获得上述输出吗？

的print_r（$标题）将得到这样的：

阵列（[0] =>这是第一个[1] =>这是第二[2] =>这是第三[3] =>这是六[4] =>这是四[5] =>这是五[6] =>这是七）

我认为你需要为此运行你的自定义SQL。例如：

global $wpdb; // your DB object 
    $sql = "SELECT m.meta_value FROM wp_postmeta m where m.meta_key = 'cap-display_name' and m.post_id = {$post_id} order by m.meta_id"; 
    $results = $wpdb->get_results($sql); 
    foreach($results as $result) 
    { 
     echo 'hello '.$result->meta_value.'<br><br>'; 
    }
