N0L1m1t5 Posted July 21, 2011 Author Share Posted July 21, 2011 My first page only has the basic features so far: (posted below) <html> <body> <form action = 'login.php' method = 'POST'> Username: <input type='text' name = 'username'><br> Password: <input type = 'password' name = 'password'><br> <input type = 'submit' value = 'Log in'> </body> </html> But i keep getting that same error Quote Link to comment Share on other sites More sharing options...
Maknib Posted July 21, 2011 Share Posted July 21, 2011 are you sure there is a $row['username'] ? Quote Link to comment Share on other sites More sharing options...
N0L1m1t5 Posted July 21, 2011 Author Share Posted July 21, 2011 so what exactly does $row['username'] do and mean? is there a replacement code I could enter and test? thanks Quote Link to comment Share on other sites More sharing options...
Maknib Posted July 21, 2011 Share Posted July 21, 2011 so what exactly does $row['username'] do and mean? is there a replacement code I could enter and test? thanks While a row of data exists, put that row in $row as an associative array. If you're expecting just one row, no need to use a loop which im guessing that there wont be more than 1 person with the same username. try changing this $numrows= mysql_num_rows($query); if ($numrows!=0) { while($row = mysql_fetch_assoc($query)) { $dbusername = $row['username']; $dbpassword = $row['password']; } to this $numrows= mysql_num_rows($query); if ($numrows!=0) { $row = mysql_fetch_assoc($query); print_r($row); { } Quote Link to comment Share on other sites More sharing options...
dilum Posted July 21, 2011 Share Posted July 21, 2011 Put you code inside curly brackets : if( isset($_POST['submit']) && $_POST['Log in']) { // you code....... } Quote Link to comment Share on other sites More sharing options...
