Protection of pages

[mmarif4u]

Hi guys:

 

I have 4 pages, i want to protect them from illegal use.

Now take an example a user go to 3rd page and thier he copied the url from address bar

and save it any where.

Next time when he put the url in the adress he will get the required page...

But i dont want this, If he paste the url and click go he see a page where

he is redirected to 1st page or some error thier on the page that u did not fill the from in the

previous pages please click here to start again...

 

I know that this is done by sessions...

I have a little bit idea of sessions i apply also but no luck.

My pages are ready and working.

But only this problem,

How can i do this to protect my pages from illegal use.(specailly when they want

to insert or update a record in db).

 

Any help will be apprecieted.

Thanks

If in fact, you don't want to use sessions, try

 

if (!$_SERVER['HTTP_REFERER']){

  print "This page can't be accessed directly. Please click back to start over.";

  }

else {

DO THIS

}
