nsstudio Posted August 3, 2005 Share Posted August 3, 2005 PLEASE HELP! This is sooo frustrating... I've created a search form that allows users to search a variety of fields - the more crietria they type in the narrower the results get. Dreamweaver MX has created the code, and it works, HOWEVER it won't return any results that have a NULL value for any of the query variables. For example, let's say I have a simple mySQL table that has the fields "name_first", "name_last", and "address". And I have 3 records - the first two have values for all three fields, and the third record only has first & last name but the address is NULL. If I do any kind of search, with or without search criteria, that third record doesn't show up. Here's my Dreamweaver-created code for the RESULTS page (only relevant code is included below): <?php require_once('../Connections/bhleadmin.php'); ?> <?php $colnamefirst_rsStaff = "%"; if (isset($HTTP_POST_VARS['name_first'])) { $colnamefirst_rsStaff = (get_magic_quotes_gpc()) ? $HTTP_POST_VARS['name_first'] : addslashes($HTTP_POST_VARS['name_first']); } $colnamelast_rsStaff = "%"; if (isset($HTTP_POST_VARS['name_last'])) { $colnamelast_rsStaff = (get_magic_quotes_gpc()) ? $HTTP_POST_VARS['name_last'] : addslashes($HTTP_POST_VARS['name_last']); } $coladdress_rsStaff = "%"; if (isset($HTTP_POST_VARS['address'])) { $coladdress_rsStaff = (get_magic_quotes_gpc()) ? $HTTP_POST_VARS['address'] : addslashes($HTTP_POST_VARS['address']); } mysql_select_db($database_bhleadmin, $bhleadmin); $query_rsStaff = sprintf("SELECT * FROM staff WHERE name_first LIKE '%%%s%%' AND name_last LIKE '%%%s%%' AND address LIKE '%%%s%%' ORDER BY id ASC", $colnamefirst_rsStaff,$colnamelast_rsStaff,$coladdress_rsStaff); $rsStaff = mysql_query($query_rsStaff, $bhleadmin) or die(mysql_error()); $row_rsStaff = mysql_fetch_assoc($rsStaff); $totalRows_rsStaff = mysql_num_rows($rsStaff); I've been experimenting with variations of "IS NULL" so that if no criteria is submitted for that field in the search form, then it will return both % and NULL fields, but I can't seem to get it to work. Here is one of the many variations I tried (I threw out all of the Dreamweaver code) - in this case the records with NULL fields DID show up, but then my search criteria had no effect - all the records showed up no matter what I searched for. <?php require_once('../Connections/bhleadmin.php'); ?> <?php if (strlen($_POST['address']) <> "") $varaddress = "address LIKE " + $_POST['address']; else $varaddress = "(address LIKE '%' OR address IS NULL)"; $customquery = "$varaddress"; mysql_select_db($database_bhleadmin, $bhleadmin); $query_rsStaff = ("SELECT * FROM staff WHERE $customquery ORDER BY id ASC"); $rsStaff = mysql_query($query_rsStaff, $bhleadmin) or die(mysql_error()); $row_rsStaff = mysql_fetch_assoc($rsStaff); $totalRows_rsStaff = mysql_num_rows($rsStaff); This seems like the most basic function - can anyone out there help? I've gotten this to work in the past using ASP: <%@LANGUAGE="VBSCRIPT"%> <!--#include file="../Connections/clients.asp" --> <% Set rsResults = Server.CreateObject("ADODB.Recordset") rsResults.ActiveConnection = MM_clients_STRING rsResults.Source = "SELECT * FROM Clients" dim appendSymbol appendSymbol = " WHERE " if (Request.Form("Name") <> "") then rsResults.Source = rsResults.Source + appendSymbol + "Name LIKE '%" + Request.Form("Name") + "%'" if (appendSymbol = " WHERE ") then appendSymbol = " AND " end if if (Request.Form("Sex") <> "") then rsResults.Source = rsResults.Source + appendSymbol + "Sex LIKE '" + Request.Form("Sex") + "'" if (appendSymbol = " WHERE ") then appendSymbol = " AND " end if rsResults.CursorType = 0 rsResults.CursorLocation = 2 rsResults.LockType = 1 rsResults.Open() rsResults_numRows = 0 %> Any help is sincerely appreciated, as I'm stuck on this project until I can figure this out!
