Using page 1 items in page 3

Question

hi, i can't use page 1 items such as P1_USERNAME in page 3 through i write " &P1_USERNAME. " in html region. Is there any way to use page 1 variable or form area in page 3? thanks.

Answer 1

actually, i want to do a login form. But my login form not Apex's default login form. I have an excel document there are employees, i will convert this excel to database table to use in database. Then i want to a login form.
Login form has 2 textfield, username and password. If user press submit button after filling the textfields, i redirect this login page to loginhandle page, this page check password, if it is true, login handle page redirects user to page 4, if it is wrong login handle page redirects user to page5.
So, i have a process in loginhandle page to perform redirection. There is conditionally branch. I've written in conditional expression a pl sql block. This block call a function, that fucntion return true or false. That function get username and password as parameters. If i do this
declare
begin
boola := check_pass(:P1_USERNAME,'1234');
return boola;
end;
the P1_USERNAME value is couldn't understand and the function doesnt work. If i do this:
declare
begin
boola := check_pass('FUAT','1234');
return boola;
end;
everything work perfect. As i mentioned earlier, the above function is written in loginhandle page.
Why do not i get the P1_USERNAME?
Thanks
