Fir this to work, there are lots of edits needed. but here are the basics:
First you should put your input and submit, in a form with action to admin.php and you should add a name to input.
second on the admin.php you get the results by using php $_GET and use it to show the result.
This is the whole idea. You can search according to this to make your code work.
