This path should be how to write AH (I am a beginner to the younger brother)

How should this path be written? (I am a rookie ~~~~~)
I use the DEDECMS system built by the website, Php+mysql, under the virtual host has three directories: Web, Data, logo

I now want to move the database folder data under the Web directory to the data directory under the virtual host, the folder has been moved OK


How to change the relative path of the two configuration files?


This is the path for the common.inc.php file to be changed:

Define (' Dededata ', dederoot. '/data ');


This is the path of the system background template cache directory to change:

/data/tplcache
------Solution--------------------
Try $_server[' Document_root ']
Define (' Dededata ', $_server[' document_root '). ' /data ');

------Solution--------------------
Dederoot should be defined to point to the web, and you move the data directory to the Web directory peer directory data. So you can no longer use Dederoot as the path top. You can redefine a constant to the data directory, and then use the new constant to connect to the data directory.
