flashy 0 Report post Posted April 25, 2008 Hi, i'm new to php. Actually i was handed with a school project which is to create a e-commerce site. However i have no basic knowledge on php. Right now i'm actually trying to create a login/register page. I tried out your tutorial in the 1st page of this thread but ends up with errors here and there. So if you could provide me with more understanding on these coding, i'll be gratful.1) I keep getting this error when trying to register... kept trying.. but all it came out was "Error: User not added to database."2) I have tried creating a user n pass in the database (mysql) and then went on to tried to login.. but all i get was "Sorry, could not log you in. Wrong login information." And also on top of the login box n password box, there are a few error message:3) On the members page as well:4) Logout page display: Notice from rvalkass: Quotes added around error messages. Ahh - i know your problem, it happens in cookies too - when you sendSESSION_START() You need to place it before everything else in your page - so like<?phpblablabla?><html>... Like that - hope it helps Share this post Link to post Share on other sites

And this was really helpful. I hope you wouldn't mind if I copied it Thank you... Share this post Link to post Share on other sites
Sefru 0 Report post Posted May 2, 2008 Everything except the login worked for me here. It says "Sorry, could not log you in. Wrong login information." when I try to login, even when I KNOW I'm using the right username/password combo. Any help?I'm having exactly the same problem. I'm 100% that I'm writing them right, I have tried to register and login many times but everytime when I try to login it just says that I have wrong login information. I have checked my database and every user I have registered is there. Share this post Link to post Share on other sites
enten41 0 Report post Posted March 30, 2009 I have been quite busy lately, trying to design and code my site (far from done XD). And after having learned how to make a simple login, I will try to write my own tutorial, for you the tutorial Step 1: The first step in designing a member system is to plan out exactly what you need. A common impulse among programmers is to jump right in and start coding. I'll be honest and admit that I'm guilty of this more so than anyone. However, since I'm in control of this conversation (yes!), you'll have it all planned out by reading through this before you even see any code. What will you need to start? First of all, you need a server that supports a CGI or Server-side language. For this tutorial, it's PHP. I won't be directing any attention to any other language at this time, so although the concepts will be similar, the code will be entirely different than something you might use in Perl or ASP. As a side note, it is possible to perform a member system simply using JavaScript, but it would not be remotely secure because JavaScript is client-side (thus able to be viewed by anyone), and even if you had a one-way encryption script it would not be feasible because of the pain of hard-coding usernames and encrypted passwords into the HTML document. Second, at least for our purposes, you need a database. Preferably MySQL. PHP and MySQL go hand-in-hand, so a lot of servers tend to match the two up. Thus, since we're talking PHP, we may as well talk MySQL. Third, you will need 4 blank PHP web pages entitled: register.php, login.php, members.php, and logout.php. After you have these pages created and open, we're ready to start. Step 2: Database If we want to design a members system, we'll need a database. So all we need to do in this step is to create the table we will use to manage the user's login information. Note that the schema we use here is quite simple, and is only simplified to help you see how it works. Name the table "dbUsers." It will need 4 fields: [I]Name Type Addition[/I] id int(10) Primary Key, AUTO_INCREMENT username varchar(16) Unique password char(16) email varchar(25) Once you've made the database table, you're ready to design and code the registration page. Create a File to Connect to your Database Create a new file and name it dbConfig.php. This file will contain the PHP code that will connect to the MySQL database, and select the correct database. Make sure you have added users to your MySQL database with read/write or admin access, then place this type of code into the dbConfig.php file: <? // Replace the variable values below // with your specific database information. $host = "localhost"; $user = "UserName"; $pass = "Password"; $db = "dbName"; // This part sets up the connection to the // database (so you don't need to reopen the connection // again on the same page). $ms = mysql_pconnect($host, $user, $pass); if ( !$ms ) { echo "Error connecting to database.\n"; } // Then you need to make sure the database you want // is selected. mysql_select_db($db); ?> Step 3: Register register.php On your registration page, you need to create a web form that will allow the user to plugin a username, password, and their e-mail address. Then, also on your page, add code that runs only when information has been passed via the form. Finally, display a "Registration Successful!" message to the user. <?php // dbConfig.php is a file that contains your // database connection information. This // tutorial assumes a connection is made from // this existing file. include ("dbConfig.php"); //Input vaildation and the dbase code if ( $_GET["op"] == "reg" ) { $bInputFlag = false; foreach ( $_POST as $field ) { if ($field == "") { $bInputFlag = false; } else { $bInputFlag = true; } } // If we had problems with the input, exit with error if ($bInputFlag == false) { die( "Problem with your registration info. " ."Please go back and try again."); } // Fields are clear, add user to database // Setup query $q = "INSERT INTO `dbUsers` (`username`,`password`,`email`) " ."VALUES ('".$_POST["username"]."', " ."PASSWORD('".$_POST["password"]."'), " ."'".$_POST["email"]."')"; // Run query $r = mysql_query($q); // Make sure query inserted user successfully if ( !mysql_insert_id() ) { die("Error: User not added to database."); } else { // Redirect to thank you page. Header("Location: register.php?op=thanks"); } } // end if //The thank you page elseif ( $_GET["op"] == "thanks" ) { echo "<h2>Thanks for registering!</h2>"; } //The web form for input ability else { echo "<form action=\"?op=reg\" method=\"POST\">\n"; echo "Username: <input name=\"username\" MAXLENGTH=\"16\"><br />\n"; echo "Password: <input type=\"password\" name=\"password\" MAXLENGTH=\"16\"><br />\n"; echo "Email Address: <input name=\"email\" MAXLENGTH=\"25\"><br />\n"; echo "<input type=\"submit\">\n"; echo "</form>\n"; } // EOF ?> Step 4: Login login.php Now in PHP, first we need to check the username and password against the information stored in the database. Since when the user registered, we encrypted their password using the MySQL PASSWORD() function, we re-encrypt the password the user supplied in the login form and cross-check this with the existing value in the dBase. If login information is O.K., then we need to use sessions to store the user's ID so they can access member-only content. <?php session_start(); // dBase file include "dbConfig.php"; if ($_GET["op"] == "login") { if (!$_POST["username"] || !$_POST["password"]) { die("You need to provide a username and password."); } // Create query $q = "SELECT * FROM `dbUsers` " ."WHERE `username`='".$_POST["username"]."' " ."AND `password`=PASSWORD('".$_POST["password"]."') " ."LIMIT 1"; // Run query $r = mysql_query($q); if ( $obj = @mysql_fetch_object($r) ) { // Login good, create session variables $_SESSION["valid_id"] = $obj->id; $_SESSION["valid_user"] = $_POST["username"]; $_SESSION["valid_time"] = time(); // Redirect to member page Header("Location: members.php"); } else { // Login not successful die("Sorry, could not log you in. Wrong login information."); } } else { //If all went right the Web form appears and users can log in echo "<form action=\"?op=login\" method=\"POST\">"; echo "Username: <input name=\"username\" size=\"15\"><br />"; echo "Password: <input type=\"password\" name=\"password\" size=\"8\"><br />"; echo "<input type=\"submit\" value=\"Login\">"; echo "</form>"; } ?> Step 5: Members Area members.php Now that the user has logged in successfully, and has his id, username, and login stored in session variables, we can start working with member-only content. A major thing to remember is that any page you want to carry session data over to you must declare a session_start(); at the top of your code. <?php session_start(); if (!$_SESSION["valid_user"]) { // User not logged in, redirect to login page Header("Location: login.php"); } // Member only content // ... // ... // ... // Display Member information echo "<p>User ID: " . $_SESSION["valid_id"]; echo "<p>Username: " . $_SESSION["valid_user"]; echo "<p>Logged in: " . date("m/d/Y", $_SESSION["valid_time"]); // Display logout link echo "<p><a href=\"logout.php\">Click here to logout!</a></p>"; ?> Step 6: Logout logout.php Ah, although it would be nice if our user's never left our web sites, we should give them to opportunity to log out and destroy the session variables if they so choose. It's quite easy to do, and you can just copy and paste this one. <?php session_start(); session_unset(); session_destroy(); // Logged out, return home. Header("Location: index.php"); ?> That's about it!. I used many simple examples hoping that you will learn how the internal systems work so you can expand on them and design a system that's just right for your needs. Have fun! I was able to insert username, password, and e-mail address but when I go to login.php and enter username and password this is not directed to members.php. It just stays on the page. Any ideas?

iGuest 3 Report post Posted September 4, 2009 Solved password problemPhp Simple Login TutorialI could not get the script to allow me to log in, after some troubleshooting I noticed that defining the password field in the DB as 16 chars was limiting the hash, and once I used MD5 with 32 chars defined it worked fine.

iGuest 3 Report post Posted October 1, 2009 php register and loginPhp Simple Login TutorialWith regards to the last comments and the login rejection. I've found a fix! Change the MySQL dbUsers password column to char(60) rather than 16. A simple password like 'test' requires 40 characters after the encryption so if its only possible to return 16, this wont be adequate to read the password correctly. thanks Great script!
