The admin in this:: In which file is defined?
Reply to discussion (solution)
From the writing point of view, the admin should be a class. The U method is his method of fetching the URL believe you should know, is in no way, you can output it in action.
By convention
The admin class is defined in the portal file admin.php of the Admin group.
No definition file found.
So you're looking at someone else's code?
Yes, in learning, one may be defined in alias.php, one defined in config.php, and another convention. PHP definition, but none of the three files ... Where else could it be defined?
