You can use $POST, $GET, $_SESSION, etc.

i have two php page (search.php,search_form.php) displaying center and right frame,when user select keyword(year or subject) from search_form.php(example 2008) then it result will display in search.php page and in this page there is paging option (i.e displaying only 10 records /page) for these i have to maintain search keyword there fore i have used session

Compare the incoming search keyword with the one stored in the session. If it is different, reset the page counter in the session.

When I say "keyword" I mean the search subject. It does not necessarily have to be a word.

Actually, it all depends on how you want to do it. A typical pagination method would use links instead, upon which you just process based on the search subject and the page, and thus use $_REQUEST (so it works both by form submission and by the query string of a link) and do not need sessions.

thanks for ur reply

ya ur rite,but whn i use paging option submitted value will get null bcouse page
will get refresh, to maintain this submitted value i m using session,

my doubt is suppose if user whn to search based on other keyword(based on year or subject or both year and subject) then i want to cleary previous session value,
do u know how can i clear a previous session values when user submit other keyword from search_form.php page but session is created on search.php page,

please let to know any idea on this,

thanks for reply

$_SESSION['search_terms'] = '';

That will clear out whatever value. You just set that specific session key to an empty string. You could even set it to null if you wanted.

You shouldn't need to use $POST more than once, and the rest can be done with $GET. What laserlight suggested earlier was creating a URL like this for the page links:

$link = 'http://www.domain.tld/search.php?term=' . urlencode($_POST['term']) . '&page=2';

You'd just use that same setup. Of course you'd need to differentiate between $POST and $GET, or just use $_REQUEST as laserlight pointed out.
