This is exactly what happeing :
as someone opens the website,first of all list of all users openup eg First name, last name, address, phone no etc then registered user can modify their details by clciking on their name .
after clciking on name a form opens up and user can modify the details.
Now problem is that:AS user points the mouse on his nmae(clickble link) bottom bar of browser shows:
www.test.com/edit_member.php/?id=john12
same thing happens when user clciks on his name to modify, URL address bar code shows
http://www.test.com/loginn_frm.php?go2url=edit_member.php%3Fid%3Djohn12
