Achilleas: The only way I can see to do this is use either:
Advertising
* GET variables (passed in the URL's query string) * Sessions * Cookies The first one is the easiest to do, I wouldn't worry about "ugly" query strings, if it works it works, and no-ones gonna want to freak the URL of their own search results are they? - even if they do, you can have a default screen that takes them back to the initial search page. You could then use the form method GET instead of POST in the actual search page, then break-up the resulting $_GET[] or $HTTP_GET_VARS[] array (depends on which PHP version you use) and include these array elements in hyperlinks or as hidden field values in another form, whichever method you use to allow users to re-order the results. There is a limit though on the length of query string you can use, something like 256 characters I think. Session would be OK too, and fairly simple to deploy, just make sure you kil off the session each time a new order instruction is given. I havn;t used cookies yet, so consult php.net for that one, but I would have thought that a little overkill! ;-) HTH :-) Russ -----Original Message----- From: Achilleas Maroulis [mailto:[EMAIL PROTECTED]] Sent: Wednesday, August 28, 2002 7:36 PM To: [EMAIL PROTECTED] Subject: [PHP-DB] Reload the page without losing variables Hi. I have a little problem concerning passing variables or reloading the page. I have a search fom page (search.php) which POSTS some variables to another page displaying the results (results.php). What I want to do is to let the users change the order of appearance in the last page. I thought I should use a variable named $order and put it into the select string like this: SELECT fields... FROM tables... WHERE expresions ORDER BY $order ASC and then make a link of the header of each column like this: <a href=\"results.php?order=HEADER_NAME\">HEADER_NAME</a> This would force the page to reload with a new order of appearance of the results but if I do this I will lose all the other variables that came to this page by the previous form. I wonder if there is a better way to refresh the page, without losing my variables, than using sessions or by sending again all my variables through the url (it would become too big and ugly...)
