How to classify the content of a php article with the article

Write by yourself You can create different tables in the database.

The basic idea: add a field to the comment table to store the ID of the article, and then when querying the database, the comment is taken by the ID of the article, so that the rest of the comments are associated with the article.

The specific implementation involves the following points:

Clause. 3. Display is sufficient.

I hope to be able to give you a basic idea.

When displaying an article, you need to go to the article table to get the information of that article through the primary key of the article, and then go to the comment table through the primary key of the article to get the comment information of the article. The next step is to display the information. God's.

That's it. Simple, right.

Just pass the cid in, get method.

cid = isset($_get['cid']) get['cid'] :0;

post method.

cid = isset($_post['cid']) post['cid'] :0;

cid = 4;

dopage->getpage("select * from `#@__infolist` where (classid=$cid or

parentstr like '%,$cid,%') and delstate='' and checkinfo=true order by

orderid desc",13);

$dopage->getpage("select * from `#@__infolist` where (classid=$cid or parentstr like '%,$cid,%') and delstate='' and checkinfo=true order by orderid desc",13);

classid is already a condition, $cid is it passed from the page?

The OR condition expands the range of options.

You change or to and see.

Yours, click on the title to enter the page, jump to the page that shows the article if($get['act']=="")

nid=$_get["id"];

teachedit=$db->query("select * from notice where id='$id'");

My suggestion is to use the custom sql tag of phpcms to query the v9 type table.

If you want to output categories and contents, or categories and columns, perform a multi-table query.

I don't know what your table structure looks like, the header and content are different fields? If that's the case, you can customize the method, select the title field in the title() method, and echo it out, and select the content field in the content() method, and echo it out, isn't it!

It is also possible to take the same tag tag to get articles with the same tag.

Count it yourself! You can categorize the articles! You can see that the current user is viewing the articles in that category, and then display a few articles in the same category at random!
