虽然我只是想从数据库中提取数据，但只要页面显示数据，它就会发送电子邮件。如何阻止它立即发送电子邮件。我想要发生的是我从数据库中检索数据＆gt;将其显示在页面＆gt;编辑页面＆gt;更新数据库并发送电子邮件。这是我希望发送电子邮件的唯一点。
根据建议，这是我的整个编辑代码，
$update = filter_input_array(INPUT_POST, $update_args);
$date = filter_input_array(INPUT_POST, $date_args);
$result = NULL;
$colcomments = NULL;
$dsn = 'mysql:dbname='.DBname.';host='.DBhost.';port=';
try {
$conn = new PDO($dsn, DBuser, DBpswd);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
if(isset($_POST['submit'])) {
if(!isset($_SESSION['update'])) {
$_SESSION['update'] = true;
//retrieve values from database
if($date['from'] !== NULL && $date['to'] !== NULL){
// get table data
$sql = 'SELECT `id`, `changeid`,
FROM `tracker` WHERE `scheduled_start_date` BETWEEN :d1 AND :d2';
$stmt = $conn->prepare($sql);
$stmt->bindParam(':d1', $date['from'], PDO::PARAM_STR);
$stmt->bindParam(':d2', $date['to'], PDO::PARAM_STR);
$stmt->execute();
$result = $stmt->fetchAll(PDO::FETCH_ASSOC);
}
}else {
unset($_SESSION['update']);
//put your mail function here

您提供的代码并不具备所有内容，因此我将解释它应如何运作
if(isset($_POST['submit'])) {
if(!isset($_SESSION['update'])) {
$_SESSION['update'] = true;
//retrieve values from database
}else {
unset($_SESSION['update']);
//put your mail function here
//update database records
}
}else {
//show the normal calender/form
}
我希望这会对你有所帮助。
如果您还有其他需要，请告诉我。我在这里帮忙。祝你好运！
