hello,
I'm a beginner when it comes to PHP:
I'm working on a log in system but i keep on getting the same errors which makes my system unreliable.
this is the function I'm trying to use:
if(pg_numrows($q) == 1){
echo "<p>Someone took that username</p>";
include "signup.php";
exit;
}
--> I'm using a postgresql database
this is the warning I keep on getting:
Warning: pg_numrows(): supplied argument is not a valid PostgreSQL result resource in /var/ftpdirs/512544/PHP/login/adduser.php on line 13
I have the same problem when I try to look if an username is taken or not... when people try to register
this is my adduser.php file:
<?php
session_start();
include "connectie_db.php";
$User_name = $_POST['user_name'] ;
$User_pass = $_POST['user_pass'] ;
$User_pass2 = $_POST['user_pass2'] ;
$checkUsername= "SELECT user_name from tovanu.users where user_name = '$User_name';";
$q = $db->exec($checkUsername);
if(MDB2::isError($q)){
echo "code: ".$q->getUserInfo();
exit();
}
if(pg_numrows($q) == 1){
echo "<p>Someone took that username</p>";
include "signup.php";
exit;
}
If(strlen($User_name > 32)){
echo "<p>The username is too long</p>";
include "signup.php";
exit;
}
if($User_pass != $User_pass2){
echo "<p>Both passwords must be the same</p>";
include "signup.php";
exit;
}
$password = md5($User_pass);
$add = "INSERT INTO tovanu.users
(user_name,user_pass,user_email,user_date,user_level,naam,adres,plaats,postcode)
VALUES ('$User_name','$password','email',current_date,1,'jef','jonhstraat','maaseik','3687')";
$execute = $db->exec($add) ;
if(MDB2::isError($execute)){
echo "code: ".$q->getUserInfo();
exit();
}
$_SESSION['user'] = $username;
include "index.php";
?>
any help would be appreciated!!!!!!!!!!!
