Thank you for your time.

I get this error:


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 'where Username='admin' and Password='1234' LIMIT 1' at line 1

The code is:

$mysql = mysql_query("SELECT * FROM tblUsers where Username='".$username."' and Password='".$password."' LIMIT 1") or die(mysql_error());
			while($row = mysql_fetch_assoc($mysql)){
				$userId = $row['UserID'];
				$user = $row['Admin'];
			}
	function loggedIn() {
		if(isset($_SESSION['username'])) {
			$username = $_SESSION['username'];
			$password = $_SESSION['password'];
			$mysql = mysql_query("SELECT * FROM tblUsers where Username='".$username."' and Password='".$password."' LIMIT 1") or die(mysql_error());
			$destroy = true;
			while($row = mysql_fetch_assoc($mysql)){
			$_SESSION['dbid'] = $row['UserID'];
		        $_SESSION['mgroup'] = $row['Admin'];
				$destroy  = false;
			}

 

Many thanks.

 

EDIT: I only posted a bit of the code, the area where the problem is.

I think it is the second one which gives the error.

Here is the code:

index.php

<?php
session_start();
		$dbuser="xxx";
		$dbpass="xxx";
		$dbname = "xxx";
		$host = "xxx";
		$chandle = mysql_connect($host, $dbuser, $dbpass) 
		or die("Connection Failure to Database");
		mysql_select_db($dbname, $chandle) or die ($dbname . " Database not found." . $dbuser);
		$user = 0;
		$userId = -1;
			$mysql = mysql_query("SELECT * FROM tblUsers where Username='".$username."' and Password='".$password."' LIMIT 1") or die(mysql_error());
			while($row = mysql_fetch_assoc($mysql)){
				$userId = $row['UserID'];
				$user = $row['Admin'];
			}
	function loggedIn() {
		if(isset($_SESSION['username'])) {
			$username = $_SESSION['username'];
			$password = $_SESSION['password'];
			$mysql = mysql_query("SELECT * FROM tblUsers where Username='".$username."' and Password='".$password."' LIMIT 1") or die(mysql_error());
			$destroy = true;
			while($row = mysql_fetch_assoc($mysql)){
			$_SESSION['dbid'] = $row['UserID'];
		        $_SESSION['mgroup'] = $row['Admin'];
				$destroy  = false;
			}
			if($destroy) {
				echo 'Your password has changed. You must relogin.';
				session_destroy();
				return false;
			}
		echo $user;
		return true;
			} else {
				echo 'Welcome guest, please <a href="index.php?x=login">Login</a>.';
			} 
		return false;
