sending variables to another page

[spearchilduser]

i have problem :

 

I have a page(page1) that sends details to the login page(page2) to check if the details are correct checks these and if there is a match it directs them to the next page.(page 3)

 

The page1 sends 3 details to the page 2 that are stored into variavles but as there is no submittion when they check the details how do i then send these details onto the page 3 ?

use sessions session_start

 

page2.php

session_start();
$_SESSION['val1'] = $_POST['val1'];
header("location: page3.php");
exit;

 

page3.php

session_start();
echo $_SESSION['val1'];

[spearchilduser]

ok the on page 3 can i then delete this from the session becuase on page 3 i store them into a tbale so i dont need them any more

 

[spearchilduser]

or clear them

[The Little Guy]

you can use unset

 

// unset 1 item
unset($_SESSION['val1']);

// unset multiple items
unset($_SESSION['val1'], $_SESSION['val2'], $_SESSION['val3']);

// unset all session data
unset($_SESSION);

Yeah, as LittleGuy said SESSION variables are the way to go in most cases, but you could also use GET variables depending on the situation. For example using GET variables could allow an external link to submit to the page as well; which could either be incredibly helpful or disastrous.
