Đối với các câu trả lời khác (đặc biệt là câu trả lời toán học), tốt hơn hết là bạn nên sử dụng trực tiếp một số javascript trên trang để xác thực các câu trả lời trước khi cho phép gửi biểu mẫu? Toán học có thể được thực hiện như thế này if(empty($answerbox))
{
echo "Please answer the math question. ";
}
elseif ($answer!=15)
{
echo "Oh oh, the answer seems wrong...";
}
else
{
// Something else?
}
Tôi nghĩ rằng bạn cũng có thể hiểu sai về vị trí và cách thức PHP chạy. Tất cả mã PHP được thực thi trên máy chủ trước khi nó đến tay người dùng. Bạn không thể kiểm tra câu trả lời thông qua PHP cho đến khi bạn gửi biểu mẫu của mình và xử lý nó trên máy chủ PHP là ngôn ngữ lập trình được sử dụng để tạo các ứng dụng web tương tác. Nó là một ngôn ngữ phía máy chủ phổ biến Trong hướng dẫn này, sẽ xây dựng một biểu mẫu liên hệ bằng PHP. Nó sẽ bao gồm các tính năng như xác thực biểu mẫu, khả năng gửi email bằng máy chủ Gmail SMTP và thư viện PHPMailer Biểu mẫu liên hệ cuối cùng của chúng tôi sẽ trông như hình bên dưới Mục lục- điều kiện tiên quyết
- Tổng quan và thiết lập dự án
- Dự án mới PHP
- Tạo biểu mẫu
- Xác thực mẫu trong PHP
- Gửi Email bằng PHP Mailer và Google Gmail SMTP server
- Phần kết luận
điều kiện tiên quyếtĐể làm theo hướng dẫn này, người đọc nên - Có hiểu biết cơ bản về HTML và PHP
- Đã cài đặt PHP và XAMPP. Chúng tôi sẽ sử dụng XAMPP để chạy PHP cục bộ trên máy của bạn
Sử dụng trang này để tải xuống và cài đặt XAMPP Tổng quan và thiết lập dự ánTrong phần này, chúng tôi sẽ thiết lập dự án của chúng tôi. Lưu ý rằng hướng dẫn này sử dụng XAMPP (môi trường phát triển PHP đa nền tảng miễn phí) Do đó, sau khi cài đặt, hãy khởi động mô-đun <!DOCTYPE html>

Chuyện gì đang xảy ra ở đây - Chúng tôi đã tạo một biểu mẫu cơ bản bằng phương thức POST để cuối cùng gửi yêu cầu trở lại trang này
Để tìm hiểu thêm về các biểu mẫu PHP, hãy xem bài viết tuyệt vời này
Chúng tôi cũng đang sử dụng materializeCSS cho một số kiểu dáng mặc định Chúng tôi đã thêm một số biến PHP trong trang HTML của mình để lặp lại thông báo lỗi hoặc giá trị được nhập vào biểu mẫu. Lưu ý rằng chúng tôi chưa tạo các biến này trong tập lệnh PHP của mình nên nó sẽ tạo ra một số lỗi nếu bạn làm mới trình duyệt của mình
Hàm htmlspecialchars được sử dụng để thay đổi các ký tự đặc biệt thành những ký tự mà HTML có thể hiểu và hiển thị đúng cách. Điều này ngăn chặn các lỗ hổng như tấn công kịch bản chéo trang (XSS) bằng cách thay thế tất cả các ký tự có hại bằng các thực thể HTML vô hại. Do đó, hãy luôn bao gồm chức năng này khi xuất đầu vào của người dùng trong HTML của bạn
Xác thực biểu mẫu trong PHPTrong phần này, chúng tôi sẽ tạo logic của trang web của chúng tôi trong <!DOCTYPE html>

0Bạn nên biết điều gì Trong đoạn mã trên - Chúng tôi đã bao gồm các gói và tệp cho giao thức PHPMailer và SMTP
- Chúng tôi khởi tạo Trình gửi thư PHP, định cấu hình nó để sử dụng giao thức SMTP và thêm thông tin xác thực

2Chuyện gì đang xảy ra ở đây - Chúng tôi đã thêm người gửi email và tên (chức năng setFrom)
- Chúng tôi cũng đã thêm người nhận email (chức năng addAddress)
- Chúng tôi đã thêm chủ đề và nội dung và cuối cùng đã gửi thư
Phần kết luậnTrong hướng dẫn này, chúng ta đã học cách thêm biểu mẫu liên hệ vào trang web PHP. Chúng tôi cũng đã xem xét cách gửi email bằng tài khoản Gmail của Google và thư viện PHPMailer
Làm cách nào để gửi email từ một biểu mẫu trong PHP?
Máy chủ lưu trữ web của chúng tôi chạy máy chủ thư cục bộ mà tập lệnh PHP có thể sử dụng để gửi email. Điều này có thể được thực hiện bằng chức năng thư dựng sẵn của PHP. $headers = "Từ. $email_addressn"; $sent = mail('you@domain. com', 'Gửi biểu mẫu phản hồi', $feedback, $headers); Đảm bảo bạn đặt địa chỉ email của mình ở dòng 2.
Làm cách nào để tạo biểu mẫu liên hệ và gửi email trong PHP?
Biểu mẫu liên hệ qua email PHP . Mã phải khớp với phương thức biểu mẫu Định cấu hình máy chủ thư localhost đúng cách Sử dụng một gói gửi thư khác Bật thư tùy chỉnh của PHP. đăng nhập Sử dụng API/SMTP với nhà cung cấp dịch vụ mail uy tín Làm cách nào để gửi email xác nhận cho người dùng sau khi gửi biểu mẫu bằng PHP?
1 câu trả lời . tạo một trường được kích hoạt trong cơ sở dữ liệu (mặc định là sai) Sau khi đăng ký, email được gửi Điền một liên kết trong email, để bao gồm. a) mã định danh duy nhất của người dùng b) kích hoạt để hoạt động. . Tập lệnh đăng ký của bạn cố lấy người dùng theo id Cập nhật trường đã kích hoạt thành true Làm cách nào để xác thực email bằng PHP?
Bạn có thể thực hiện email xác thực PHP bằng cách sử dụng hàm filter_var() và chuyển email và id bộ lọc đã cho “FILTER_VALIDATE_EMAIL” làm đối số . Id bộ lọc đã nêu sẽ kiểm tra xem định dạng của email có đúng theo cú pháp trong RFC 822 không. |
