ThinkPHP unlimited classification principle to implement the message and reply function instance, thinkphp instance

The message board program described in this article uses the principle of unlimited classification to enable unlimited messages and replies. The message list gclist retains spaces at the message level, so that the message-reply level is distinct. Share it with you for your reference. The specific analysis is as follows:

Function, this program can provide unlimited messages and replies, that is, reply to messages and reply to messages. Of course, you can also make limited control to only reply to messages. The key is to remove "reply to this message" from the reply message in the template code. Welcome to shoot bricks!

-- Table structure for 'wb _ guestbook'
------------------------------
Drop table if exists 'wb _ guestbook ';
Create table 'eway _ guestbook '(

'Inputtime' int (10) not null,
'Content' text not null,

'Isreply' tinyint (1) not null,
'Status' tinyint (1) not null,
Primary key ('id ')

I hope this article will help you with ThinkPHP framework programming.

The php Message Board provides unlimited replies.

I personally think it is okay to create a special database table. I will reply to each id and write the reply corresponding to this id to the table after each reply!
Reply content table:
Reply Id reply content

Reply to join table:
Reply content id reply Content id

In this way, you can implement unlimited replies!
