Change Personal Data (from other users, Front end)

Hello All,

I want to change the ModulePersonalData (into a small module)

What i want to achieve is that i have a url like "getuserprofile.php?user=4"

i want to change the ModulePersonalData from getting the loged in user id to the "$_GET['user']" where "$_GET['user']" will be '4'.

So i can change personal data from other user beside my own data.

What i did,

i copy'd ModulePersonalData to its own folder and changed its name.
Now i'm stuck to set the user id to the GET variable.

This is the module what i copied : https://github.com/contao/core/blob/...rsonalData.php

Hope someone can help me with this.

Is there a way that i can set :

PHP Code:

---

$this->;import('FrontendUser', 'User'); 


---

Where i can set 'User' or 'FrontendUser' to a user id?

What i want to achieve is that i can use the

PHP Code:

---

$this->user-> 


---

that's the easiest way i thank for the obstacle explained above
