【问题描述】：
我已经制作了一个包含以下字段的联系表：姓名、电子邮件、消息。一切正常 - 消息已发送到我的电子邮件 - 直到我将附件选项添加到表单中。
我尝试通过搜索教程来验证附件字段，但似乎没有任何效果。我想我只是不确定如何将它实现到我已经存在的代码中。这里有什么帮助吗？
表格如下：
<?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> <input type="file" id="attachment1" name="attachment[]" size="35">
<label for="attachment2">File:</label> <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 $data;
}
点击提交按钮后，它只是将我带到 index.php 页面.. 任何帮助表示赞赏！
【问题讨论】：
-
您以错误的方式使用邮件 php... 使用：
if (mail($to, '=?UTF-8?B?' . base64_encode($subject) . '?=', $datamsg, $headers, "-f$email")) {因为$datamsg已经包含您的$message，请使用末尾的第 5 个参数"-f$email"强制发送... -
使用常量
PHP_EOL而不是\n这将允许服务器调整在服务器的操作系统托管中使用的代码... -
您阅读我的完整答案了吗？
action="<?= $SERVER['PHP_SELF']; ?>"是错误的，您可以在我的回答的第 5) 和 6) 点阅读。 -
我建议采用这种方法...例如：
if (empty($_POST["thename"])) { $error = "Palun sisesta nimi"; include("form.php"); exit(); }。对每个字段重复$email、$message...等...在form.php中，您只需要<div class="error"><span><?php echo $error; ?></span></div>。
