hi Folks,

 

I have a simple login script that uses PHP/Mysql and i want to expand it slightly.

 

the execution script is below for the login, i was looking to add somthing along the lines of

 

If 'login' equals 'Admin' then redirect to 'custompages/admin/home.php'

 

is this possiable or do i need a completely new script.

 

<?php
//Start session
session_start();

//Include database connection details
require_once('config.php');

//Array to store validation errors
$errmsg_arr = array();

//Validation error flag
$errflag = false;

//Connect to mysql server
$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
if(!$link) {
	die('Failed to connect to server: ' . mysql_error());
}

//Select database
$db = mysql_select_db(DB_DATABASE);
if(!$db) {
	die("Unable to select database");
}

//Function to sanitize values received from the form. Prevents SQL injection
function clean($str) {
	$str = @trim($str);
	if(get_magic_quotes_gpc()) {
		$str = stripslashes($str);
	}
	return mysql_real_escape_string($str);
}

//Sanitize the POST values
$login = clean($_POST['login']);
$password = clean($_POST['password']);

//Input Validations
if($login == '') {
	$errmsg_arr[] = 'Login ID missing';
	$errflag = true;
}
if($password == '') {
	$errmsg_arr[] = 'Password missing';
	$errflag = true;
}

//If there are input validations, redirect back to the login form
if($errflag) {
	$_SESSION['ERRMSG_ARR'] = $errmsg_arr;
	session_write_close();
	header("location: login-form.php");
	exit();
}

//Create query
$qry="SELECT * FROM members WHERE login='$login' AND passwd='".md5($_POST['password'])."'";
$result=mysql_query($qry);

//Check whether the query was successful or not
if($result) {
	if(mysql_num_rows($result) == 1) {
		//Login Successful
		session_regenerate_id();
		$member = mysql_fetch_assoc($result);
		$_SESSION['SESS_MEMBER_ID'] = $member['member_id'];
		$_SESSION['SESS_FIRST_NAME'] = $member['firstname'];
		$_SESSION['SESS_LAST_NAME'] = $member['lastname'];
		session_write_close();
		header("location: member-index.php");//change as appropriate
		exit();
	}else {
		//Login failed
		header("location: login-failed.php");
		exit();
	}
}else {
	die("Query failed");
}
?>

you mean something like this?

<?php
//Start session
session_start();

//Include database connection details
require_once('config.php');

//Array to store validation errors
$errmsg_arr = array();

//Validation error flag
$errflag = false;

//Connect to mysql server
$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
if(!$link) {
	die('Failed to connect to server: ' . mysql_error());
}

//Select database
$db = mysql_select_db(DB_DATABASE);
if(!$db) {
	die("Unable to select database");
}

//Function to sanitize values received from the form. Prevents SQL injection
function clean($str) {
	$str = @trim($str);
	if(get_magic_quotes_gpc()) {
		$str = stripslashes($str);
	}
	return mysql_real_escape_string($str);
}

//Sanitize the POST values
$login = clean($_POST['login']);
$password = clean($_POST['password']);

//Input Validations
if($login == '') {
	$errmsg_arr[] = 'Login ID missing';
	$errflag = true;
}
if($password == '') {
	$errmsg_arr[] = 'Password missing';
	$errflag = true;
}

//If there are input validations, redirect back to the login form
if($errflag) {
	$_SESSION['ERRMSG_ARR'] = $errmsg_arr;
	session_write_close();
	header("location: login-form.php");
	exit();
}

//Create query
$qry="SELECT * FROM members WHERE login='$login' AND passwd='".md5($_POST['password'])."'";
$result=mysql_query($qry);

		$_SESSION['SESS_FIRST_NAME'] = $member['firstname'];
		$_SESSION['SESS_LAST_NAME'] = $member['lastname'];
		session_write_close();
                        switch($login)
                       {
                         case 'user': $direction = 'member-index.php';
                         break;
                         case 'Admin': $direction = 'admin-index.php';
                         break;

                        }

	die("Query failed");
}
?>

Yeah thats the trick, thanks.

 

quick question would i be able to use a simlar way to redirect based on a db entry? for example is member_id '2' logs in it would redirect to a preset page in the db??

yeah, just store the location in the db then once you have confirmed that they have a valid login assign the location to a variable and use it to redirect. for example you had a variable in your table called homepage:

// query run here

if($result) {
	if(mysql_num_rows($result) == 1) {
		//Login Successful
		session_regenerate_id();
		$member = mysql_fetch_assoc($result);
		$_SESSION['SESS_MEMBER_ID'] = $member['member_id'];
		$_SESSION['SESS_FIRST_NAME'] = $member['firstname'];
		$_SESSION['SESS_LAST_NAME'] = $member['lastname'];
		session_write_close();
                        $page = $member['homepage'] ;
		header("location: $page");//change as appropriate
		exit();
	}else {
		//Login failed
		header("location: login-failed.php");
		exit();
	}
}
