Inside testing2 php you should print the   POST array which contains all the data from the post  Also    POST  name   should be available  For more info check   POST on php net

I think you should need to check for isset and not empty value  like form was submitted without input data so isset will be true This will prevent you to have any error or notice   if  isset   POST  name      amp  amp   empty   POST  name            name     POST  name      note i used   POST since you have a post form   method  post        echo  name

In testing2 php use the following code to get the name   if     empty   POST  name           name     POST  name         When you create the next page  use the value of  name to prefill the form field   Name   lt input type  text  name  name  id  name  value   lt  php echo  name    gt   gt  lt br  gt    However  before doing that  be sure to use regular expressions to verify that the  name only contains valid characters  such as    pattern        0-9A-Za-z  -    -                  integers  amp  letters if  preg match  pattern   name     1         continue   else         reload form with error message

You are posting the data  so it should be   POST  But  name  is not the best name to use   name    name    will only cause confusion IMO
