DarkPrince2005 Posted August 20, 2008 Author Share Posted August 20, 2008 I found another script that also works, but as soon as I add a where clause to the queries it returns an error saying that 'selection' is an undefined index.

akitchin Posted August 20, 2008 Share Posted August 20, 2008 undefined index is not an error, it's a notice. notices won't completely halt your script, they're mostly to point out sloppy coding. does the code actually work, or is there an actual issue apart from the notice?

akitchin Posted August 20, 2008 Share Posted August 20, 2008 sorry, i should have looked closer. $_POST values won't propagate from page to page unless you do something to get them to. that usually requires putting them into the URL as a $_GET parameter. assuming you will always have a selection, you could adjust the links to look like this: echo "<a href=\"".$_SERVER['PHP_SELF']."?page=$prev&selection={$_GET['selection']}\"><<Previous</a> "; this requires that you use $_GET['selection'] rather than $_POST['selection'] in the query, and that you assign it as soon as you've arrived from the form: // set the selection in the GET parameters if it isn't already there $_GET['selection'] = (isset($_POST['selection'])) ? $_POST['selection'] : $_GET['selection']; note that this is a crude fix; it doesn't account for when the page is accessed neither from the form nor the results (in which case neither $_POST['selection'] or $_GET['selection'] are set).
