Login Tutorial
Step 1
Requirements
MySQL Database
PHP
Flash
Step 2
Creating a Table
Open PhpMyAdmin
Login to your Database
Then press a button called "SQL".
And a box shall apear.
Now...
Make sure you change *Databasename* to your database name...
Then enter the following;
CREATE TABLE `databasename`.`users` (`id` INT(11) NOT NULL AUTO_INCREMENT,
`username` VARCHAR(300) NOT NULL, `password` VARCHAR(300) NOT NULL, PRIMARY KEY (`id`)) ENGINE = MyISAM;
Step 3
Connecting to Database
First off all in your filemanager create a file called login.php or another name which you could remember and type the following code into the file.
<? $dbhost = 'localhost'; // Usally Localhost use this unless specifyed by host.
$dbuser = 'root'; // The username of the database you create (sometimes the same as databasename)
$dbpass = 'password'; // The database password
$conn = mysql_connect($dbhost, $dbuser, $dbpass) or die('Error connecting to mysql');
$dbname = 'changeme'; // The database name
mysql_select_db($dbname);
?>
Step 4
Setting up the flash side of things.
First draw two text feilds username and password. Set them to a input feild and change the var name on username to 'username' and the var name on password to you guessed it 'password'.
Now create a button.
And open action script and type;
on(press){
this.user = username;
this.pass = password;
loadVariablesNum("http://www.example.com/login.php", 0, "POST");
}
Now on frame of the login we need;
_root.onEnterFrame = function(){
if(_root.loadLogin == "OK"){
_root.gotoAndStop("SUCESS");
}
if(_root.loadLogin == "KO"){
trace("Incorrect username and or password");
}
}
Step 5
Register Page
Unfortiatly to explain how to connect this with flash. After learning all this you should be able to make one your self.
So make a page called register.php or what ever.
Then first make the HTML side of things. So copy the following.
<head><title>YOUR SITE - Register</title></head>
<form action="" method="post">
Username: <input type="input" name="username"><br>
Password: <input type="password" name="password"><br>
<input type="submit" value="Register" name="go">
</form>
Now open the login.php and copy the PHP Database bit from last time and add it to the top (be sure to include the <? ?>).
Now we need to make the PHP bit so under the database bit put the following code.
<?
if($_POST['go']){
$username = $_POST['username'];
$password = $_POST['password'];
$sql = mysql_query("SELECT * FROM users WHERE username='$username'");
$row = mysql_num_rows($sql);
if($row != 0){
echo"Sorry $username that Username Taken!";
}else{
mysql_query("INSERT INTO `users` (`id`, `username`, `password`)VALUES ('','$username','$password')");
echo"Regged";
}
}
?>
Step 6
Completing the login!
Now we have register and the flash and database set up the next thing to do is add the following. After the database connection.
<?
$username = $_POST['username'];
$password = $_POST['password'];
$sql = mysql_query("SELECT * FROM users WHERE username='$username' AND password='$password'");
$row = mysql_num_rows($sql);
if($row != 0){
print"loadLogin=OK";
}else{
print"loadLogin=KO";
}
?>
