you can use this:

1st page (page1.php)

<form action="page2.php" method="post">     <input type="text" name="firstname" value="" />     <input type="text" name="lastname" value="" />     <input type="submit" value="submit" /> </form> 

2nd (page2.php)

retrieve , validate $_post['firstname'] , $_post['lastname'], create output required data, can use hidden fields or create links, according needs. instance:

$firstname = $_post['firstname']; $lastname  = $_post['lastname'];  // output links can pass data method echo '<a href="page3.php?firstname='.$firstname.'&lastname='.$lastname.'"></a>';  // output hidden fields, can use post or method or javascript/ajax echo ' <form action="page3.php" method="get">     <input type="hidden" name="firstname" value="'.$firstname.'" />     <input type="hidden" name="lastname" value="'.$lastname.'" />     <input type="submit" value="submit" /> </form>'; 

3rd page (page3.php)

if use solution link or form method, can retrieve data in page3.php doing following:

$firstname = $_get['firstname']; $lastname  = $_get['lastname']; 

hope can you!
