Загруженный файл отправляется на сервер, но не с вложением почты

Question

Я новичок в php-кодировании. У меня есть контактная форма на моем веб-сайте, которая позволяет пользователю отправлять файлы в виде вложений на электронную почту.

По ссылкам в интернете мне наконец-то удалось отправить электронное письмо через контактную форму. Таким образом, вопрос в том, что файл загружается на сервер, но почта достигает без каких-либо вложений .

Я создал папку с именем upload и туда отправляется только файл Я что-то пропустил. Ниже код, который я использую:

HTML:

<form action="send_form_email.php" method="post" enctype="multipart/form-data" name="servicesform" id="servicesform" autocomplete="on">
  <div class="control-group form-group">
    <div class="controls">

Answer 1

Итак, как я сказал в комментариях, вы должны использовать Swift Mailer или PHPMailer . Я немного исправил ваш код, но все еще есть части, которые не очень хороши.

И самое главное: не изобретайте велосипед - уже есть отличные почтовые библиотеки. Функция mail() должна использоваться только в качестве базового слоя для библиотек, никогда не отправляйте электронные письма с ней в своем коде.

Что я сделал:

• заменил ваш чек регулярного выражения на filter_var()
• отредактировал ваше расширение и проверку типа пантомимы с помощью чего-то более удобочитаемого
• добавил код, необходимый для отправки вложения (не проверял его, возможно, он не работает должным образом, но должен)
• заменен синтаксис длинного массива (array()) на синтаксис короткого массива ([])

Что я не делал:

• Я не полировал ваш код, чтобы он был более читабельным
• Я не устранил проблему с перемещением файла (вы не должны использовать относительный путь, поэтому было бы лучше с чем-то вроде этого: move_uploaded_file($_FILES["uploads"]["tmp_name"], __DIR__."/upload/" . $_FILES["uploads"]["name"]);)

В любом случае, вот ваш код.

<?php
if (isset($_POST['email'])) {

    // TO AND FROM
    $emailTo = "info@mysite.com";
    $emailSubject = "Enquiry from my website";

    function died($error)
    {
        // ERROR MESSAGES TO THE USER
        echo "We are very sorry, but there were error(s) found with the form you submitted. ";
        echo "These errors appear below.<br /><br />";
        echo $error . "<br /><br />";
        echo "Please go back and fix these errors.<br /><br />";
        die();
    }

    // VALIDATION ON EXPECTED DATA
    if (!isset($_POST['yourname']) ||
        !isset($_POST['phone']) ||
        !isset($_POST['email']) ||
        !isset($_POST['enquiring']) ||
        !isset($_POST['field'])) {
        died('We are sorry, but there appears to be a problem with the form you submitted.');
    }

    $nameFrom = $_POST['yourname']; // required
    $phone = $_POST['phone']; // not required
    $emailFrom = $_POST['email']; // required
    $enquiring = $_POST['enquiring']; // not required
    $field = $_POST['field']; // not required
    $uploads = $_FILES['uploads']; // not required

    // MANDATORY FIELDS
    $errorMessage = "";
    if (!filter_var($emailFrom, FILTER_VALIDATE_EMAIL)) {
        $errorMessage .= 'The email address you entered does not appear to be valid.<br />';
    }
    // commented out, users whose names include special characters (á, ý, etc.) would be filtered out
//    $stringExp = "/^[A-Za-z .'-]+$/";
//    if (!preg_match($stringExp, $nameFrom)) {
//        $errorMessage .= 'The name you entered does not appear to be valid.<br />';
//    }
    if (strlen($errorMessage)) {
        died($errorMessage);
    }
    $emailMessage = "Services Form.\n\n";

    function clean_string($string)
    {
        $bad = ["content-type", "bcc:", "to:", "cc:", "href"];
        return str_replace($bad, "", $string);
    }

    $emailMessage .= "Name: " . clean_string($nameFrom) . "\n";
