whatnow Posted March 2, 2006 Share Posted March 2, 2006 I do intend to minimse on posting stupid threads but please allow me this one...feckin noob that I am. ALL i wanted to do was get a single result from my database. I've searched many online books my uni provide and i've trawled the net but I never got a proper explination of how to use mysql_db_query that I had to ask here. I know how to call it, I just can't get my query right, take a look:[code]$cookie_info = explode("-", $_COOKIE['mysite_username']);$usernameCookie = $cookie_info[0];mysql_connect($server, $db_user, $db_pass) or die (mysql_error()); $result = mysql_db_query($database, "SELECT image FROM $table WHERE username = '$usernameCookie'") or die (mysql_error()); echo "username: $usernameCookie result: $result image: $image";if (mysql_num_rows($result)) { echo "list of users:<ul>"; while ($qry = mysql_fetch_array($result)) { echo "<li>$qry[username]</li>"; } echo "</ul>end list of users."; }[/code]I chose the query becuase I have a table which is $table from my config file, this is read fine. The structure of the table is:usernamepasswordimageI can echo $username so it's read correctly from the cookie but I can't select the user's 'image' variable (URL of a image) from the DB. this is what's outputted from the code:[!--html--][div class=\'htmltop\']HTML[/div][div class=\'htmlmain\'][!--html1--]username: qwerty result: Resource id #5 image: list of users:end list of users.[!--html2--][/div][!--html3--]It's mystified me, after a day learning php this is the thing that i've spent most time on and got nowhere with. After the 3rd hour I had to post on here as I was going around in circles ! tia.

earl_dc10 Posted March 2, 2006 Share Posted March 2, 2006 mysql_db_query has been depreciated, more info here:[a href=\"http://us2.php.net/manual/en/function.mysql-db-query.php\" target=\"_blank\"]http://us2.php.net/manual/en/function.mysql-db-query.php[/a]try this and see if it works[code]<?php$link = mysql_connect......$db_select = mysql_select_db(<database name>, $link);$query = "SELECT image FROM $table WHERE username = '$usernameCookie'";$result = mysql_query($query, $link) or die("Couldn't select result".mysql_error() );echo mysql_result($result, 0);?>[/code] Quote Link to comment https://forums.phpfreaks.com/topic/3951-pulling-a-single-result-from-a-db-using-a-query/#findComment-13728 Share on other sites More sharing options...
