無法從我的php聯系人表單獲取電子郵件

Question

我有一個contact.html表單，該表單將字段提交給contact.php腳本； 但是，我的收件箱中沒有收到電子郵件。 是，收件人：電子郵件地址正確。 這是表單網頁的地址，這是contact.php的代碼

<?php

    $my_email = "jlvazquez825@gmail.com";
    $final_msg = "";

    //validation function
    function validate($data) {
        $data = trim($data); //removing white space and tabs
        $data = stripslashes($data); //removing \
        $data = htmlspecialchars($data); //converting to html
        return $data;
    }

    if($_SERVER['REQUEST_METHOD'] == "POST") {
            $name = validate($_POST["name"]);
            $email = validate($_POST["email"]);
            $subject = validate($_POST["subject"]);
            $message = validate($_POST["message"]);

    }
    $final_msg += "name: " . $name . "\n" .
                 "email: " . $email . "\n" .
                 "subject: " . $subject . "\n" .
                 "message: ". $message;

    $headers = "From: miatech@sohotechnology.org \r\n" . "Reply-To: " . $email . "\r\n";

    if(mail($my_email, $subject, $final_msg, $headers)) {
        echo "<b>Your Message Was Successfuly Sent!... Thanks</b>" . "<br>";
        echo "<b>name: </b>" . $name . "<br>";
        echo "<b>email: </b>" . $email . "<br>";
        echo "<b>subject: </b>" . $subject . "<br>";
        echo "<b>message: </b>" . $message;
    }
    else {
        echo "<b>Your Message Could not be Sent!... Sorry</b>";
    }


?>

您使用錯誤的串聯運算符。

字符串的正確值是.= ，而不是+= 。

$final_msg .= '...';

然后，如果表單已發送，則一切都應處於良好狀態。 現在，您嘗試每次加載腳本時都發送郵件，具體取決於（成功）發送表單的事實。

if($_SERVER['REQUEST_METHOD'] == "POST") {
    // sanitize form data, prepare $headers, $final_msg here
    if (mail(...)) {
        ...
    } else {
        ...
    }
}

條件應該是

if (filter_var($_POST['mail'], FILTER_VALIDATE_EMAIL) &&
    !empty($_POST['name']) && 
    !empty($_POST['subject']) &&
    !empty($_POST['message'])
) {
    //
} else {
    // incomplete form was sent, or data are incorrect
}

if($_SERVER['REQUEST_METHOD'] == "POST") {指令
