DiscuzX3 how a single entry file can be modified to jump to your own. PHP page

Http://localhost/discuz/forum.php?mod=mypost

This is my local file, forum_mypost.php is a new file placed under the module, modified the forum.php below the $modarray array, but is not corresponding to the file, seek expert guidance?

Reply to discussion (solution)

Did not modify the template ah?

Debug, look, there's a problem in that line.

The recommendations are as follows:
1, if you lazy, you directly in the entrance to the mouth to jump directly to your method
2, if you want to study, suggest you to change his bottom of the default configuration

Thank you for the problem. The PHP file itself is a problem

Discuz background navigation can be directly set AH, but also need to change the code it!?

You just create a new navigation, link to the file you want, and then set as the default home page, OK!
