Question

我在index.php文件中直接使用PDO查詢。現在我想創建單獨的文件，我將存儲函數。我創建了一個，但是當我調用函數時只返回「0」。舊版本的作品：

$abfrage11 = "SELECT COUNT(e.event_id) as numgoals 
FROM event e 
WHERE (e.match_id = '$row1->match_id' AND e.team_id = '$row1->team_a_id' AND e.eventtype IN ('soc_G','soc_PG')) OR 
     (e.match_id = '$row1->match_id' AND e.team_id = '$row1->team_b_id' AND e.eventtype = 'soc_OG')"; 
$ergebnis11 = $dbh->query($abfrage11); 
$row11 = $ergebnis11->fetch(PDO::FETCH_OBJ); 

但在新版本中沒有：

單獨的文件 「storage.php」：

class StorageAccess 
{ 
    /** @var PDO */ 
    public $db; 

    /** 
    * @param $db 
    */ 
    public function __construct($db) 
    { 
     $this->db = $db; 

    } 
public function getAbfrage11() 
    { 
     $query = "SELECT COUNT(e.event_id) as numgoals 
        FROM event e 
        WHERE (e.match_id = :mId AND e.team_id = :tmA AND e.eventtype IN ('soc_G','soc_PG')) OR 
          (e.match_id = :mId2 AND e.team_id = :tmB AND e.eventtype = 'soc_OG')"; 
     $statement = $this->db->prepare($query); 
     $statement->execute([ 
      ':mId' => $row1->match_id, 
      ':mId2' => $row1->match_id, 
      ':tmA' => $row1->team_a_id, 
      ':tmB' => $row1->team_b_id, 
     ]); 
     return $statement->fetchObject(); 
    } 
} 

呼叫的index.php：

require_once("dblogin.php"); 
require_once("Storage.php"); 

$dbFactory = new RepositoriesFactory(); 
$dbh = $dbFactory->getDataBaseInstance('admgsa_gsa'); 
$storage_access = new StorageAccess($dbh); 

$row11 = $storage_access->getAbfrage11(); 
echo "<span class='live-monitor-8' style=\"$goalscbgcolor\">$row11->numgoals</span>"; 

嘗試尋找解決方案，但找不到任何東西。提前感謝您的幫助。

得到了什麼問題。我沒有指定輸入參數：

public function getAbfrage11($row1) 
    { 
     $query = "SELECT COUNT(e.event_id) as numgoals 
        FROM event e 
        WHERE (e.match_id = :mId AND e.team_id = :tmA AND e.eventtype IN ('soc_G','soc_PG')) OR 
          (e.match_id = :mId2 AND e.team_id = :tmB AND e.eventtype = 'soc_OG')"; 
     $statement = $this->db->prepare($query); 
     $statement->execute([ 
      ':mId' => $row1->match_id, 
      ':mId2' => $row1->match_id, 
      ':tmA' => $row1->team_a_id, 
      ':tmB' => $row1->team_b_id, 
     ]); 
     return $statement->fetchObject(); 
    } 

這解決了我的問題。
