techker Posted February 15, 2009 Share Posted February 15, 2009 hey guys i was wondering on how i can get info from my database from a select box. like i tryed this with no luck: <? require "config2.php"; $connection = mysql_connect($dbhost, $dbusername, $dbpass); $SelectedDB = mysql_select_db($dbname); $cat=$_GET['cat']; $QQQ1 = mysql_query(" SELECT id, pic FROM $cat "); if(!$QQQ1) die(mysql_error()); $err = mysql_num_rows($QQQ1); if($err == 0) die("No matches met your criteria."); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <body> <form id="form1" name="form1" method="post" action=""> <label> <select onchange="reload(this.form)" name="cat" id="cat"> <option value="ABS">ABS</option> <option value="ARMS">ARMS</option> </select> </label> </form> <? while ($line = mysql_fetch_array($QQQ1)) { echo "<option value=\"$line[id]\">$line[pic] </option>"; }?> </body> </html> You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1 im shure it's because it is executing the query before i chose the categorie?

fenway Posted February 16, 2009 Share Posted February 16, 2009 That's so very exposed to sql injection... echo your query string. Link to comment https://forums.phpfreaks.com/topic/145310-select-box/#findComment-763209 Share on other sites More sharing options...

fenway Posted February 16, 2009 Share Posted February 16, 2009 The query that's causing the error -- I want to see it (not the php code). Link to comment https://forums.phpfreaks.com/topic/145310-select-box/#findComment-763316 Share on other sites More sharing options...

fenway Posted February 17, 2009 Share Posted February 17, 2009 SELECT DISTINCT pic,id FROM $cat Not exactly... that's _still_ php code... echo that string.

fenway Posted February 18, 2009 Share Posted February 18, 2009 Don't post links to code... no one's going to look at them. "Refreshing" is not a mysql problem... if that's really the issue, but the queries work just fine, then I'll move this thread to the PHP forum.
