Question

我正在尝试从树屋的博客Click here获取Jquery Ajax联系表单。我试图通过删除“消息字段”来编辑表单。来自HTML和JS

我在表单中提交详细信息后收到错误消息。 Code pen link

以下是我的代码片段。

HTML：

<form id="ajax-contact" class="main-contact submit-fade ajax-form" action="register.php" method="POST">
    <ul class="small-block-grid-2 medium-block-grid-2 hide-form">
        <li>
            <label for="name">Name</label>
            <input type="text" class="form-control" name="name" placeholder="Name" required>
        </li>

        <li>
            <label for="email">Email</label>
            <input type="text" class="form-control" name="email" placeholder="Email">
        </li>
    </ul>
    <input type="submit" class="btn btn-success">
</form>

JS：

var form = $('#ajax-contact');
var formMessages = $('#form-messages');

$(form).submit(function(e) {

    e.preventDefault();
    var formData = $(form).serialize();

    // Submit the form using AJAX.
    $.ajax({
        type: 'POST',
        url: $(form).attr('action'),
        data: formData
    })
    .done(function(response) {
        // Make sure that the formMessages div has the 'success' class.
        $(formMessages).removeClass('error');
        $(formMessages).addClass('success');

        // Set the message text.
        $(formMessages).text(response);

        // Clear the form.
        $('#name').val('');
        $('#email').val('');
        //$('#message').val('');
    })
    .fail(function(data) {
        // Make sure that the formMessages div has the 'error' class.
        $(formMessages).removeClass('success');
        $(formMessages).addClass('error');

        // Set the message text.
        if (data.responseText !== '') {
            $(formMessages).text(data.responseText);
        } else {
            $(formMessages).text('Oops! An error occured and your message could not be sent.');
        }
    });

});

PHP：

<?php
    if ($_SERVER["REQUEST_METHOD"] == "POST") {
        // Get the form fields and remove whitespace.
        $name = strip_tags(trim($_POST["name"]));
        $name = str_replace(array("\r","\n"),array(" "," "),$name);
        $email = filter_var(trim($_POST["email"]), FILTER_SANITIZE_EMAIL);
        $message = trim($_POST["message"]);

        // Check that data was sent to the mailer.
        if ( empty($name) OR empty($message) OR !filter_var($email, FILTER_VALIDATE_EMAIL)) {
            // Set a 400 (bad request) response code and exit.
            http_response_code(400);
            echo "Oops! There was a problem with your submission. Please complete the form and try again.";
            exit;
        }

        // Set the recipient email address.
        // FIXME: Update this to your desired email address.
        $recipient = "hello@example.com";

        // Set the email subject.
        $subject = "New contact from $name";

        // Build the email content.
        $email_content = "Name: $name\n";
        $email_content .= "Email: $email\n\n";
        $email_content .= "Message:\n$message\n";

        // Build the email headers.
        $email_headers = "From: $name <$email>";

        // Send the email.
        if (mail($recipient, $subject, $email_content, $email_headers)) {
            // Set a 200 (okay) response code.
            http_response_code(200);
            echo "Thank You! Your message has been sent.";
        } else {
            // Set a 500 (internal server error) response code.
            http_response_code(500);
            echo "Oops! Something went wrong and we couldn't send your message.";
        }

    } else {
        // Not a POST request, set a 403 (forbidden) response code.
        http_response_code(403);
        echo "There was a problem with your submission, please try again.";
    }

?>

从php文件中删除所有消息变量和条件。您的代码如下所示：

<?php


if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Get the form fields and remove whitespace.
    $name = strip_tags(trim($_POST["name"]));
    $name = str_replace(array("\r","\n"),array(" "," "),$name);
    $email = filter_var(trim($_POST["email"]), FILTER_SANITIZE_EMAIL);


    // Check that data was sent to the mailer.
    if ( empty($name) OR !filter_var($email, FILTER_VALIDATE_EMAIL)) {
        // Set a 400 (bad request) response code and exit.
        http_response_code(400);
        echo "Oops! There was a problem with your submission. Please complete the form and try again.";
        exit;
    }

    // Set the recipient email address.
    // FIXME: Update this to your desired email address.
    $recipient = "hello@example.com";

    // Set the email subject.
    $subject = "New contact from $name";

    // Build the email content.
    $email_content = "Name: $name\n";
    $email_content .= "Email: $email\n\n";


    // Build the email headers.
    $email_headers = "From: $name <$email>";

    // Send the email.
    if (mail($recipient, $subject, $email_content, $email_headers)) {
        // Set a 200 (okay) response code.
        http_response_code(200);
        echo "Thank You! Your message has been sent.";
    } else {
        // Set a 500 (internal server error) response code.
        http_response_code(500);
        echo "Oops! Something went wrong and we couldn't send your message.";
    }

} else {
    // Not a POST request, set a 403 (forbidden) response code.
    http_response_code(403);
    echo "There was a problem with your submission, please try again.";
}

?>

Answer 2

通过在 /volume1/web/ 上设置读/写权限解决了错误（“糟糕！出现问题，我们无法发送您的消息。”）

Synology 支持回复：“与我们的开发人员核实后，通常使用 PHP 邮件功能不需要写权限，也不确定您的网站为什么需要它。

此外，请注意，授予 R/W 权限可能会允许某人写入甚至覆盖 /web 文件夹或子文件夹中的文件。”
