按照順序在wordpress上顯示自定義字段

Question

我在這裏有一個情況，我得到的數組自定義字段不正確。我可以知道如何讓所有自定義字段順序嗎？

，我用它來獲取自定義陣列功能是：

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

但是，我得到的輸出是：

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 

假想的輸出是：

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 

我可以知道如何獲得上述輸出嗎？

的print_r（$標題）將得到這樣的：

陣列（[0] =>這是第一個[1] =>這是第二[2] =>這是第三[3] =>這是六[4] =>這是四[5] =>這是五[6] =>這是七）

我認爲你需要爲此運行你的自定義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>'; 
    }
