php - 在 mysqli 准备中提交表单后显示成功消息

Question

如何在记录插入成功后显示成功消息。此代码运行完美，但不显示任何消息。

error_reporting(E_ALL ^ E_NOTICE);
$name=$_POST['name'];
$email=$_POST['email'];
$massage=$_POST['massage'];
$organization=$_POST['organization'];

$stmt = mysqli_prepare($connection, "INSERT INTO massage_board(name,email,organization,massage)VALUES (?, ?, ?, ?)");
mysqli_stmt_bind_param($stmt, 'ssss', $name, $email, $organization, $massage);

/* execute prepared statement */
mysqli_stmt_execute($stmt);
if($stmt->execute()){
    echo "<div id=\"success\"><h2>Your message has been sent. Thank you!</h2></div>";

header('Location:contact.html');
}else{
echo "Please retry";    
}

Answer 1

您的消息会显示，但它会重定向到另一个页面，因此您看不到它，请尝试以下代码而不在页面上重定向。

if($stmt->execute()){
    echo "<div id=\"success\"><h2>Your message has been sent. Thank you!</h2></div>";

header('Location:contact.html');   <--- Remove this line
}
