为什么我在从联系表单提交数据时收到“无法打开流"错误? [英] Why am I receiving a 'failed to open stream' error when submitting data from a contact form?

问题描述

我创建了一个 HTML5 联系表单，我目前正在使用 Swiftmailer 在本地主机 (XAMPP) 上测试该表单，单击提交按钮后，我收到以下错误:

I have created a HTML5 contact form that I'm currently testing on a local host (XAMPP) using Swiftmailer, and after clicking the submit button I get the following error:

Warning: require_once(/swift.php): failed to open stream: No such file or directory in /Applications/XAMPP/xamppfiles/htdocs/testsite/sendmessage.php on line 10

第 10 行显然是指我的 PHP 中的 require_once 行，但在我的文件中，它包含在 HTML 标记中.

Line 10 refers, obviously, to the require_once line in my PHP, however in my file it is encased in HTML tags.

我相信这个错误告诉我该文件不存在，但它确实存在，我可以毫无问题地浏览那里.

I believe that this error is telling me that the file does not exist, but it does and I can browse there with no problems.

我的 HTML 文件和 'swift.php' 文件本身都在 /Applications/XAMPP/xamppfiles/htdocs/testsite/ 所以我不确定为什么我收到这个错误.我尝试了以下方法:

Both my HTML file and the 'swift.php' file itself is in /Applications/XAMPP/xamppfiles/htdocs/testsite/ so I'm unsure why I'm getting this error. I have tried the following:

require_once(realpath(dirname(__FILE__).'swift.php')); 没有成功.

我还尝试了许多当前文件路径的排列(即像 ../ 这样的东西，包括完整的文件路径，也没有成功.

I have also tried a number of permutations of present the file path (ie things like ../, and including the full file path, also with no success.

我的 HTML (form.html) 是:

My HTML (form.html) is:

<form id="contactform" name="contact" method="post" action="sendmessage.php">
  <label for="Name">Name: *</label><br>
  <input type="text" name="Name" id="Name"><br>

  <label for="Email">Email: *</label><br>
  <input type="Email" name="Email" id="Email" class="txt"><br>

  <label for="Message">Message: *</label><br>
  <textarea name="Message" rows="20" cols="20" id="Message" class="txtarea"></textarea><br>

  <button type="submit" id="submit-button">Send E-mail</button>
</form>

我的 PHP ('sendmessage.php') 是(同样，这里没有包含在 HTML 和 BODY 标签中):

My PHP ('sendmessage.php') is (again, not encased in HTML and BODY tags here):

require_once("/swift.php");
echo 'Mail sent <br />';

// Grab the post data
$name = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
$usermail = filter_var($_POST['usermail'], FILTER_SANITIZE_EMAIL);
$content = filter_var($_POST['content'], FILTER_SANITIZE_STRING);

// Construct the body of the email
$data = "Name: " . $name . "<br />" . "Email: " . $usermail . "<br />" . "Message: " . $content;

// Create the transport
$transport = Swift_SmtpTransport::newInstance('smtp.gmail.com', 587, 'tls')
    ->setUsername('[e-mail]')
    ->setPassword('GENERATED PASSWORD');
echo 'line 26 <br />';

// Create the mailer using the created transport
$mailer = Swift_Mailer::newInstance($transport);
$message = Swift_Message::newInstance('This is the subject')
    ->setFrom(array('[e-mail]' => 'Feedback Received From User'))
    ->setTo(array('[e-mail]', '[e-mail]' => 'Lead Recipients'))
    ->setSubject('Here is your Feedback subject')
    ->setBody($data, 'text/html');
echo 'line 34 <br />';

// Send the message
$result = $mailer -> send($message);
echo $result;
echo 'line 39<br />';
?>

生成的密码"是​​您使用 Google 的两步验证时所需的特定于应用程序的密码，但这里当然已将其删除.

The 'GENERATED PASSWORD' is the app specific one required when you use Google's Two Step Verification, but this has of course been removed here.

我在这里查看了以下问题，此处，以及这里 但我似乎已经执行了给出的建议.

I have looked at the following questions here, here, and here but I appear to have carried out the advice given.

我尝试将 'require_once("/swift.php");' 修改为 'require_once("swift.php");'，但这给了我以下错误:

I have tried amending 'require_once("/swift.php");' to 'require_once("swift.php");', however this gives me the following error:

Warning: require(/Applications/XAMPP/xamppfiles/htdocs/testsite/classes/Swift.php): failed to open stream: No such file or directory in /Applications/XAMPP/xamppfiles/htdocs/testsite/swift.php on line 20

不同之处在于现在在路径中添加了一个classes"子文件夹.将 'swift.php' 放在这个文件夹中会给我原始错误.

The difference is the addition of a 'classes' subfolder now in the path. Putting 'swift.php' in this folder gives me the original error.

第 20 行供参考:

$data = "Name: " . $name . "<br />" . "Email: " . $usermail . "<br />" . "Message: " . $content;

我查看了以下代码 -

I have looked to check the following code -

在第 10 行的 sendmessage.php 中:

In sendmessage.php on line 10:

require_once(dirname(__FILE__)."/swift.php");

在第 20 行的 swift.php 中:

In swift.php on line 20:

require(dirname(__FILE__)."/classes/Swift.php");

这些都是存在的并且是正确的.检查并重新运行后的错误是:

and these are present and correct. The error following checking and re-running is:

Warning: require(/Applications/XAMPP/xamppfiles/htdocs/testsite/classes/classes/Swift.php): failed to open stream: No such file or directory in /Applications/XAMPP/xamppfiles/htdocs/testsite/classes/Swift.php on line 20

每次我添加其中一个文件夹时，它似乎都在寻找一个额外的类"文件夹.

It appears to be looking for an extra 'classes' folder every time I add one of those folders.

推荐答案

总结一下:

/Applications/XAMPP/xamppfiles/htdocs/testsite/sendmessage.php
/Applications/XAMPP/xamppfiles/htdocs/testsite/swift.php
/Applications/XAMPP/xamppfiles/htdocs/testsite/classes/Swift.php

在第 10 行的 sendmessage.php 中:

In sendmessage.php on line 10:

require_once(dirname(__FILE__)."/swift.php");

在第 20 行的 swift.php 中:

In swift.php on line 20:

require(dirname(__FILE__)."/classes/Swift.php");
