biff423 Posted July 25, 2011 Share Posted July 25, 2011 I am trying to query using the results of a search form. One of the fields I have is "state". I would like the user to be able to select multiple states and then get a list of results reflecting all the states selected. This is the code I have used for a single select form element for state. It reflects selecting all records if no selection is made for state, as well as sex, sale and salename: $query = "SELECT *, DATE_FORMAT(saledate,'%m/%d/%Y') as saledatex FROM sdusa WHERE"; if (!empty($state)){ $query .= " state = '$state' AND";} if (!empty($sex)){ $query .= " sex = '$sex' AND";} if (!empty($sale)){ $query .= " breeder = '$sale' AND";} if (!empty($salename)){ $query .= " salename LIKE '%$salename%' AND";} $query .= " saledate >= $salestart AND saledate <= $saleend AND birthdate >= $birthstart AND birthdate <= $birthend AND actbw <= $actbw1 AND adj205ww >= $adj205ww1 AND adj365yw >= $adj365yw1 AND rea >= $rea1AND imf >= $imf1 AND sc >= $sc1$result = mysql_query($query) or die('Error, query failed'); How would I adjust the query to get results from a multiple select list for state that would give me a list of results that reflects all states selected? I think I need to add a "foreach" statement possibly or a counter - but since I am newer to php am not real sure of the code. Current output looks like this: <table align='center' width='780' border='1' cellpadding='0' cellspacing='0' bordercolor='#000000'> <tr><td width='55' class='s11'><div align='center'>Reg #</div></td> <td width='100' class='s11'><div align='center'>Name</div></td> <td width='135' class='s11'><div align='center'>Sire</div></td> <td width='125' class='s11'><div align='center'>MGS</div></td> <td width='180' class='s11'><div align='center'>Breeder</div></td> <td width='25' class='s11'><div align='center'>St</div></td> <td width='60' class='s11'><div align='center'>Sale Date</div></td> <td width='25' class='s11'><div align='center'>BW</div></td> <td width='25' class='s11'><div align='center'>WW</div></td> <td width='25' class='s11'><div align='center'>YW</div></td> <td width='25' class='s11'><div align='center'>M</div></td> </tr> <?php while($row = mysql_fetch_array($result)){ echo "<tr height='20'>"; echo "<td class='s11'><div align='center'><a href='sdindselect.php?registration_num=". $row ['registration_num'] ."'>" . $row['registration_num'] .

AbraCadaver Posted July 25, 2011 Share Posted July 25, 2011 Something like this, using the IN clause in the query: http://www.phpfreaks.com/forums/index.php?topic=339076.msg1598271#msg1598271 Quote Link to comment https://forums.phpfreaks.com/topic/242771-form-multiple-select-use-in-a-mysql-query/#findComment-1246923 Share on other sites More sharing options...
biff423 Posted July 25, 2011 Author Share Posted July 25, 2011 That worked fantastically as long as i am selecting states. Hoever if i don't make a selection - I want it to select ALL states. Used to acomplish this by having: <option value="" selected="selected">All States</option> Then in the query: if (!empty($state)){ $query .= " salestate = '$state' AND"; } Any ideas?

AbraCadaver Posted July 25, 2011 Share Posted July 25, 2011 Following with your previous code, this would do it wouldn't it? if (!empty($_POST['state'])) { $state_list = $makes = "'" . implode("','", array_map('mysql_real_escape_string', $_POST['state'])) . "'"; $query .= " state IN($state_list) AND"; } Quote Link to comment https://forums.phpfreaks.com/topic/242771-form-multiple-select-use-in-a-mysql-query/#findComment-1246964 Share on other sites More sharing options...
biff423 Posted July 25, 2011 Author Share Posted July 25, 2011 First question - do I need to declare the variable at the top: $state=$_POST['state']; Second question - here is the code I used per your suggestion: if (!empty($_POST['state'])) { $state_list = $makes = "'" . implode("','", array_map('mysql_real_escape_string', $_POST['state'])) . "'"; $query .= " salestate IN($state_list) AND";} It give me a correct list when I select multiple states. But if I select this: <option value="">All States</option> ...I get no results. Thoughts?

AbraCadaver Posted July 25, 2011 Share Posted July 25, 2011 Probably because if you don't supply a value it uses the text as the value. Try setting the value to 0 (which will be considered empty). Or you could do this: if (!empty($_POST['state']) && $_POST['state'] != 'All States' ) { $state_list = "'" . implode("','", array_map('mysql_real_escape_string', $_POST['state'])) . "'"; $query .= " state IN($state_list) AND"; } I would just set the All States value to 0.

biff423 Posted July 25, 2011 Author Share Posted July 25, 2011 Thank you for your patience with me!! I changed value of All States to 0 - no results - no rows returned. I used your suggested code - no results- no rows returned. You are so close - just need to be able to be able to select all records if no state is specified.

Psycho Posted July 25, 2011 Share Posted July 25, 2011 The problem is not whether you use an empty string or a "0".. The problem is that you are not checking that value correctly If using an empty string for "All States" (my preference) if ( isset($_POST['state']) && !empty($_POST['state']) ) { $state_list = "'" . implode("','", array_map('mysql_real_escape_string', $_POST['state'])) . "'"; $query .= " state IN($state_list) AND"; } If using "0" for "All States" if ( isset($_POST['state']) && $_POST['state']!='0' ) { $state_list = "'" . implode("','", array_map('mysql_real_escape_string', $_POST['state'])) . "'"; $query .= " state IN($state_list) AND"; } Quote Link to comment https://forums.phpfreaks.com/topic/242771-form-multiple-select-use-in-a-mysql-query/#findComment-1246995 Share on other sites More sharing options...
