Question

我已使用以下字段填写了联系表格：姓名，电子邮件，消息。一切正常-邮件已发送到我的电子邮件-直到我在表格中添加了附件选项。

我已经尝试通过搜索教程来验证附件字段，但是似乎没有任何效果。我想我只是不确定如何将其实现到我现有的代码中。

以下是表单：

<?php include 'contact-form.php'; ?>

<form id="contact" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" enctype="multipart/form-data">
<h3>Contact Us</h3>
<fieldset>
  <input placeholder="Nimi" type="text" tabindex="1" name="thename"  value="<?= $thename ?>" autofocus>
    <div class="error"><span><?= $name_error ?></span></div>
</fieldset>
<fieldset>
  <input placeholder="Email" type="text" tabindex="2" name="email" value="<?= $email ?>">
    <div class="error"><span><?= $email_error ?></span></div>
</fieldset>
<fieldset>
  <textarea placeholder="Sisesta sõnum siia.." type="text" tabindex="3" name="message"></textarea>
    <div class="error"><span><?= $message_error ?></span></div>
</fieldset>
<fieldset>
    <label for="attachment1">File:</label>&nbsp;<input type="file" id="attachment1" name="attachment[]" size="35">
    <label for="attachment2">File:</label>&nbsp;<input type="file" id="attachment2" name="attachment[]" size="35">
    <div class="error"><span><?= $attachment_error ?></span></div>
</fieldset>
<fieldset>
  <button name="submit" type="submit" id="contact-submit" data-submit="...Saatmine">Saada</button>
</fieldset>
<div class="success"><?= $success; ?></div>
<div class="error"><?= $error; ?></div>
</form>

这是PHP验证代码 contact-form.php ：

<?php
$name_error = $email_error = $message_error = $attachment_error = "";
$thename = $email = $message = $success = "";

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

if (empty($_POST["thename"])) {
    $name_error = "Palun sisesta nimi";
} else {
    $thename = test_input($_POST["thename"]);
    // check if name only contains letters, whitespace and hyphen
    if (!preg_match("/^[a-zA-Z -]*$/",$thename)) {
        $name_error = "Sisestada saab ainult tähti, tühikuid ja sidekriipse";
    }
}

if (empty($_POST["email"])) {
  $email_error = "Palun sisesta email";
} else {
    $email = test_input($_POST["email"]);
    // email validation
    if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
        $email_error = "Sisesta email korrektselt";
    }
}

if (empty($_POST["message"])) {
    $message_error = "Palun sisesta sõnum";
} else {
    $message = test_input($_POST["message"]);
}

if (empty($_FILES["attachment"])) {
    $attachment_error = "Palun sisesta enda eluloo fail";
}

if ($name_error == '' and $email_error == '' and $message_error == '' ){
    $message_body = '';
    unset($_POST['submit']);
    foreach ($_POST as $key => $value){
        $message_body .= "$key: $value\n";
    }


    $to = 'myemail@gmail.com';
    $subject = 'Eesti Elulood';
    $message = "Sulle saadeti kiri Rannu koguduse kodulehelt.\n\nSaatja nimi: $thename\n\nSaatja email: $email\n\nSõnum: $message";
    // create email headers
    $headers =  'From: '.$email."\r\n".
                'Reply-To: '.$email."\r\n" .
                'X-Mailer: PHP/' . phpversion();
    if (isset($_FILES['attachment']['name'])) {
$semi_rand = md5(uniqid(time()));
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
$headers = "From: " . '=?UTF-8?B?' . base64_encode($thename) . '?=' . " 
<$email>" . PHP_EOL;
$headers .= "Reply-To: " . '=?UTF-8?B?' . base64_encode($thename) . '?=' . 
" <$email>" . PHP_EOL;
$headers .= "Return-Path: $email" . PHP_EOL;
$headers .= "MIME-Version: 1.0" . PHP_EOL;
$headers .= "Content-Type: multipart/mixed;" . PHP_EOL;
$headers .= " Boundary=\"{$mime_boundary}\"";
$datamsg = "This is a multi-part message in MIME format." . PHP_EOL . 
PHP_EOL;
$datamsg .= "--{$mime_boundary}" . PHP_EOL;
$datamsg .= "Content-Type: text/plain; Charset=\"UTF-8\"" . PHP_EOL;
$datamsg .= "Content-Transfer-Encoding: 8bit" . PHP_EOL . PHP_EOL;
$datamsg .= $message . PHP_EOL . PHP_EOL;
for ($index = 0; $index < count($_FILES['attachment']['name']); $index++) 
{
if ($_FILES['attachment']['name'][$index] != "") {
  $file_name = $_FILES['attachment']['name'][$index];
  $data_file = 
chunk_split(base64_encode(file_get_contents($_FILES['attachment'] 
['tmp_name'][$index])));
  $datamsg .= "--{$mime_boundary}" . PHP_EOL;
  $datamsg .= "Content-Type: application/octet-stream; Name=\" 
{$file_name}\"" . PHP_EOL;
  $datamsg .= "Content-Disposition: attachment; Filename=\"{$file_name}\"" . PHP_EOL;
  $datamsg .= "Content-Transfer-Encoding: base64" . PHP_EOL . PHP_EOL . 
$data_file . PHP_EOL . PHP_EOL;
}
}
$datamsg .= "--{$mime_boundary}--";
}

    if (@mail($to, '=?UTF-8?B?' . base64_encode($subject) . '?=', 
$datamsg, $headers, "-f$email")){
        $success = "Thankyou, message sent!.";
    } else {
        $error = "Sorry but the email could not be sent. Please try again!";
    }   
}
}

function test_input($data) {
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}

点击提交按钮后，它将带我进入index.php页面。任何帮助表示赞赏！

Answer 1

1）除html标记外，您的php代码中没有邮件附件代码，因此您无法发送邮件附件。

2）您必须使用chunk_split(base64_encode())对附件进行编码，然后必须使用正确的方式将其导入到邮件部分。

3）您忘记输入正确的标题，这是无法发送邮件的另一个原因。

4）您必须考虑到，如果您使用GMail，则可以发送的文件类型可能会受到限制，因此请阅读以下内容：https://support.google.com/mail/answer/6590?hl=en

5）我建议您使用长php标签代替短标签：

写<?= $_SERVER['PHP_SELF']; ?>代替写<?php echo $_SERVER['PHP_SELF']; ?>

6）您的php出现严重错误，这就是为什么在您的家中按“提交”而不是联系表的原因：

<?= $SERVER['PHP_SELF']; ?>是错误的！

<?= $_SERVER['PHP_SELF']; ?>是正确的！

再见5点”

以下是正确的附件html标记示例：

<label for="attachment1">File:</label>&nbsp;<input type="file" id="attachment1" name="attachment[]" size="35">
<label for="attachment2">File:</label>&nbsp;<input type="file" id="attachment2" name="attachment[]" size="35">
<label for="attachment3">File:</label>&nbsp;<input type="file" id="attachment3" name="attachment[]" size="35">

这是附件的正确php邮件代码的示例：

if (isset($_FILES['attachment']['name'])) {
  $semi_rand = md5(uniqid(time()));
  $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
  $headers = "From: " . '=?UTF-8?B?' . base64_encode($sender_name) . '?=' . " <$from_email>" . PHP_EOL;
  $headers .= "Reply-To: " . '=?UTF-8?B?' . base64_encode($sender_name) . '?=' . " <$from_email>" . PHP_EOL;
  $headers .= "Return-Path: $from_email" . PHP_EOL;
  $headers .= "MIME-Version: 1.0" . PHP_EOL;
  $headers .= "Content-Type: multipart/mixed;" . PHP_EOL;
  $headers .= " Boundary=\"{$mime_boundary}\"";
  $datamsg = "This is a multi-part message in MIME format." . PHP_EOL . PHP_EOL;
  $datamsg .= "--{$mime_boundary}" . PHP_EOL;
  $datamsg .= "Content-Type: text/plain; Charset=\"UTF-8\"" . PHP_EOL;
  $datamsg .= "Content-Transfer-Encoding: 8bit" . PHP_EOL . PHP_EOL;
  $datamsg .= $message . PHP_EOL . PHP_EOL;
  for ($index = 0; $index < count($_FILES['attachment']['name']); $index++) {
    if ($_FILES['attachment']['name'][$index] != "") {
      $file_name = $_FILES['attachment']['name'][$index];
      $data_file = chunk_split(base64_encode(file_get_contents($_FILES['attachment']['tmp_name'][$index])));
      $datamsg .= "--{$mime_boundary}" . PHP_EOL;
      $datamsg .= "Content-Type: application/octet-stream; Name=\"{$file_name}\"" . PHP_EOL;
      $datamsg .= "Content-Disposition: attachment; Filename=\"{$file_name}\"" . PHP_EOL;
      $datamsg .= "Content-Transfer-Encoding: base64" . PHP_EOL . PHP_EOL . $data_file . PHP_EOL . PHP_EOL;
    }
  }
  $datamsg .= "--{$mime_boundary}--";
}
if (@mail($recipient_email, '=?UTF-8?B?' . base64_encode($subject) . '?=', $datamsg, $headers, "-f$from_email")) {
  exit("Files Sent Successfully");
} else {
  exit("Sorry but the email could not be sent. Please go back and try again!");
}

其中$sender_name是发件人的名称，$from_email是发件人的电子邮件，$recipient_email是您的电子邮件的收件人。

您可以从我的代码中举一个例子，并将其集成到您的项目中，我只写了有关附件发送的基本部分。

我希望这会有所帮助。

在添加附件选项之前，我的联系表工作正常。消息不再发送。知道如何验证附件字段吗？
