title: prevent url access without form submit php
body: <p>Suppose we have a form where we allow user to submit some text or so.... Then the form is submitted which passes the value to another page where we show result based on the input submitted in previous page. Now we know both url so we <strong>may try to access them directly</strong> but <em>first one is ok no problem</em>, when going to <em>acess second page it will not have the parameters or says the value to give result</em> ?????? so i want to <strong>prevent user getting direct access</strong> to this page without filling the form and submitting same from first page.    </p>
  
  <p>Eg  submit a form with text box name and next page we display details of that name from database. url may looks like for second page <code>www.domain.com/page2.php?name=somename</code>   </p>
  
  <p>Any Idea?</p>
  
  <p>*we already checked user to login when try accessing the first page</p>
