我有一個腳本，用於發送存儲在會話中的信息的電子郵件 - 信息是從用戶填寫的表單收集的。 （形式「動作」是指向下面的代碼）PHP發送電子郵件多次發送電子郵件
然而，當點擊兩次的形式例如在當提交按鈕時，2名的電子郵件的發送和點擊3次時，3個電子郵件被髮送。
我想確保只有1封電子郵件被髮送，如果任何會話是空的沒有電子郵件發送：
<?php
session_start();
if(isset($_POST['email'])) {
$email_to = "[email protected]";
$email_subject = "My Subject";
$machine = implode(",", $_SESSION['machinesesh']); //required
$machine_type = implode(" ", $_SESSION['typesesh']);; // required
$address = $_SESSION['addresssesh']; //required
$county = $_SESSION['countysesh']; //required
$postcode = $_SESSION['postcodesesh']; //required
$workplace = implode(', ', $_SESSION['worksesh']); //required
$serving = implode(', ', $_SESSION['peoplesesh']);
$company_name = $_SESSION['namesesh']; // required
$visitorname = $_POST['yourname']; // required
$email_from = $_POST['email']; // required
$telephone = $_POST['telephone']; // not required
$email_message = "New email alert .\n\n";
function clean_string($string) {
$bad = array("content-type","bcc:","to:","cc:","href");
return str_replace($bad,"",$string);
}
$email_message .= "Name: ".clean_string($visitorname)."\n";
$email_message .= "Company: ".clean_string($company_name)."\n";
$email_message .= "Address Line 1: ".clean_string($address)."\n";
$email_message .= "County: ".clean_string($county)."\n";
$email_message .= "Postcode: ".clean_string($postcode)."\n";
$email_message .= "Machine(s) Wanted: ".clean_string($machine)."\n";
$email_message .= "Environment: ".clean_string($workplace)."\n";
$email_message .= "Serving: ".clean_string($serving)."\n";
$email_message .= "Email: ".clean_string($email_from)."\n";
$email_message .= "Telephone: ".clean_string($telephone)."\n";
// create email headers
$headers = 'From: [email protected]' . "\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);
header("Location: http://www.example.com?tag=$machine");
?>
您可以爲會話添加一個計數器變量，如果它爲空/ 0 /未設置，請發送電子郵件。否則，不要。 – Antony
它發送三次（三次點擊），無需重新加載或重定向？ – Progrock
