MySQLi没有插入表

Question

我试图插入数据到MySQL表使用mysqli但这段代码不工作，我没有得到任何错误打印出来。

我可能会错过什么？

<?php 
// if the form was submitted 
if($_POST){ 

    // sql query 
    $sql2 = "INSERT INTO 
       t_incident_persons (IncidentID, PersonID, KeywordID, description) 
      VALUES 
       (?, ?, ?, ?)"; 

    // if the statement was prepared 
    if($stmt2 = $mysqli->prepare($sql2)){ 

     //bind the values, 
     $stmt2->bind_param(
      "iiis", 
      $_POST['IncidentID'], 
      $_POST['PersonID'], 
      $_POST['KeywordID'], 
      $_POST['description'] 
     ); 

     // execute the insert query 
     if($stmt2->execute()){ 
    header('Location: details.php'); 
    exit; 
      $stmt2->close(); 
     }else{ 
      die("Unable to add an incident."); 
     } 

    }else{ 
     die("Unable to prepare statement."); 
    } 

    // close the database 
    $mysqli->close(); 
} 

?>

我相信这是自动提交行为。尝试在重定向之前关闭之前关闭。

... 
if($stmt2->execute()){ 
    $stmt2->close(); 
    header('Location: details.php'); 
    exit;    
}else{ 
    die("Unable to add an incident."); 
}
