alfawolf Posted July 31, 2015 Share Posted July 31, 2015 I'm trying to fetch some value's from a database. The database contains 2 tables, when i try to join the data i get nothing, no output on screen , no text on screen. when i do the query for each, it works. now i tried several examples but nothing works....i just don't get it !? This is the code: <!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /><title>Untitled Document</title></head><body><table width="600" height="100" border="1"> <tr style="color:#00CC00"> <th width="50"></th> <th width="200">Player Name:</th> <th width="50">Player Online:</th> <th width="100">EXP Total</th> <th width="300">Player Playtime:</th> </tr> <?php$servername = "";$username = "";$password = "";$dbname = "";$port = "";// Create connection$conn = new mysqli($servername, $username, $password, $dbname, $port);// Check connectionif ($conn->connect_error) { die("Connection failed: " . $conn->connect_error);} $sql = "SELECT a.player_id, a.online, a.playtime, a.name, b.exp_total"; "FROM stats_players a, stats_misc_info_players b"; "where a.player_id=b.exp_total"; $result = $conn->query($sql); if ($result->num_rows > 0) { while($row = $result->fetch_assoc()) { ?> <tr style="color:#CCCCCC"> <td width="50"><?php echo $row["player_id"];?></td> <td width="200"><?php echo $row["name"];?></td> <td width="50"><?php echo $row["online"];?></td> <td width="100"><?php echo $row["exp_total"];?></td> <td width="300"><?php echo $row["playtime"];}} $conn->close() ?></td> </tr></table></body></html> Link to comment https://forums.phpfreaks.com/topic/297571-simple-mysql-query/ Share on other sites More sharing options...
maxxd Posted July 31, 2015 Share Posted July 31, 2015 You're ending your query string 3 different times. Try $sql = " SELECT a.player_id, a.online, a.playtime, a.name, b.exp_total FROM stats_players a, stats_misc_info_players b where a.player_id=b.exp_total "; Also, add ini_set('display_errors',true); error_reporting(-1); at the top of your script. Blank white pages mean there's an error in the code, and the above lines will force those errors to display.

Barand Posted July 31, 2015 Share Posted July 31, 2015 SELECT a.player_id, a.online, a.playtime, a.name, b.exp_total FROM stats_players a, stats_misc_info_players b where a.player_id=b.exp_total Are sure you really want to match on a.player_id=b.exp_total? Seems strange to match an id against a total, or just bad column naming. If that is the case, why bother to select both columns if you know they are going to be the same in the results Link to comment https://forums.phpfreaks.com/topic/297571-simple-mysql-query/#findComment-1517832 Share on other sites More sharing options...
