I tried to decipher your question. Apparently you want to have a form on a page called 'login.html', then have it be validated by a script called 'page.php' and then return to 'login.html', possibly only if validation failed. This could be accomplished with the header() function. For example, if you want to return to the login.html-page if validation fails:

page.php

//Validation code here

if ($validated == true)
 {
 //Validation succes
 }
else
 {
 header('Location: login.html');
 }

Notice that the header()-function won't work if you already printed something to the page.
