In the original `upload\template\default\touch\forum\viewthread.htm` we can see that the title and content are displayed separately, and the final one is `$_G [forum_thread][subject]`This variable

There is a problem at this time, that is, how to get out our theme content! Let’s first look at what the content variables of the source code are.

You can see that `forum.php` is requested first, then we Just open this file

The last line of the file is the file we finally need to enter. You can print the mod variable to see what it is

According to the above Figure, we go directly to the file `upload/source/module/forum/forum_viewthread.php`, and you will see these two variables. Are these two variables very familiar? Aren’t these the two used in our template? Variable?
