How to use PHP to develop FAQ and message board modules in CMS

With the gradual development of websites, more and more companies and organizations have begun to use websites as an important way to promote and provide services. In websites, modules such as FAQ (frequently asked questions) and message boards have also become part of daily operations. Required module. This article will introduce how to use PHP to develop FAQ and message board modules in CMS.

1. FAQ module

1. Database design

The FAQ module is mainly divided into two parts: question list and answer list. In the database, we need to create question tables and answer tables respectively, as well as association tables between questions and answers.

Question table structure:

CREATE TABLE faq_questions (
id INT(11) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
title VARCHAR(255) NOT NULL,
content TEXT,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
is_published TINYINT(1) DEFAULT 0,
user_id INT(11) UNSIGNED NOT NULL,
category_id INT(11) UNSIGNED NOT NULL,
FOREIGN KEY (user_id) REFERENCES users(id),
FOREIGN KEY (category_id) REFERENCES faq_categories(id)
);

Answer table structure:

CREATE TABLE faq_answers (
id INT(11) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
content TEXT NOT NULL,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
is_published TINYINT(1) DEFAULT 0,
user_id INT(11) UNSIGNED NOT NULL,
question_id INT(11) UNSIGNED NOT NULL,
FOREIGN KEY (user_id) REFERENCES users(id),
FOREIGN KEY (question_id) REFERENCES faq_questions(id)
);

Relationship table structure between questions and answers:

CREATE TABLE faq_question_answer (
id INT(11) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
question_id INT(11) UNSIGNED NOT NULL,
answer_id INT(11) UNSIGNED NOT NULL,
FOREIGN KEY (question_id) REFERENCES faq_questions(id),
FOREIGN KEY (answer_id) REFERENCES faq_answers (id)
);

2. Backend management interface

Backend management interface is mainly responsible for managing questions and answers, including adding, modifying, deleting and viewing operations . In the background management interface, we can display the list of questions and answers in a table, and can also perform search and filter operations.

3. Front-end display interface

In the front-end display interface, we can display the list of questions and answers by classification, and we can also quickly find the answers to the required questions through the search function . While the question is displayed, you can click on the question title to expand or collapse the corresponding answers.

2. Message board module

1. Database design

The message board module mainly includes a message list and a reply list. In the database, we need to create a message table and a reply table respectively, as well as an association table between messages and replies.

Message table structure:

CREATE TABLE messages (
id INT(11) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
content TEXT NOT NULL,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
user_id INT(11) UNSIGNED NOT NULL,
is_published TINYINT(1) DEFAULT 0,
FOREIGN KEY (user_id) REFERENCES users(id)
) ;

Reply table structure:

CREATE TABLE replies (
id INT(11) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
content TEXT NOT NULL,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
user_id INT(11) UNSIGNED NOT NULL,
message_id INT(11) UNSIGNED NOT NULL,
is_published TINYINT(1) DEFAULT 0,
FOREIGN KEY (user_id) REFERENCES users(id),
FOREIGN KEY (message_id) REFERENCES messages(id)
);

Association table structure between messages and replies:

CREATE TABLE message_reply (
id INT(11) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
message_id INT(11) UNSIGNED NOT NULL,
reply_id INT(11) UNSIGNED NOT NULL,
FOREIGN KEY (message_id) REFERENCES messages(id),
FOREIGN KEY (reply_id) REFERENCES replies(id)
);

2. Backend management interface

Backend management interface is mainly responsible for Manage messages and replies, including adding, modifying, deleting and viewing operations. In the background management interface, we can display the list of messages and replies in a table, and can also perform search and filter operations.

3. Front-end display interface

In the front-end display interface, we can display the message list in paging, and at the same time, we can view the details of a message and the method of replying to the message. area.

The above is an introduction to using PHP to develop the FAQ and message board modules in CMS. Through the above database design and development of the backend management interface, it can help us develop common modules such as website FAQ and message boards.
