Recommended Posts

Hi, everyone.  I have two questions;

1. I want to know whether i can use Dreamweaver to write my PHP scripts. And if yes! Am I going to create a separate file for the PHP script or I will add it to my HTML script.  For example:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />

<title>Authenticaton system</title>

</head>

 

<body>

 

 

<?php

$dbhost = 'localhost';

$dbuser = 'root';

$dbpass = '123dare';

 

$conn = mysql_connect($dbhost, $dbuser, $dbpass) or die                      ('Error connecting to mysql');

 

$dbname = 'mydatabase';

mysql_select_db($dbname);

?>

<?php

$db = mysql_connect ('localhost', 'username', 'password')

    or die ("Unable to connect to Database Server");

?> 

<?php

mysql_select_db ('mydatabase', $db)

    or die ("Could not select database");

?> 

<?php

/* get the incoming ID and password hash */

$user = $_POST["userid"];

$pass = sha1($_POST["password"]);

 

/* establish a connection with the database */

$server = mysql_connect("localhost", "mysql_user",

        "mysql_password");

if (!$server) die(mysql_error());

mysql_select_db("myDatabase");

 

/* SQL statement to query the database */

$query = "SELECT * FROM authentication WHERE user = '$user'

        AND Pass = '$pass'";

 

/* query the database */

$result = mysql_query($query);

 

/* Allow access if a matching record was found, else deny access. */

if (mysql_fetch_row($result))

echo "Access Granted: Welcome, $user!";

else

echo "Access Denied: Invalid Credentials.";

 

mysql_close($server); 

 

if (mysql_fetch_row($result)) {

/* access granted */

session_start();

header("Cache-control: private");

$_SESSION["access"] = "granted";

header("Location: ./secure.php");

} else

/* access denied – redirect back to login */

header("Location: ./login.html");

?> 

<?php

session_start();

header("Cache-control: private");

if ($_SESSION["access"] == "granted")

header("Location: ./secure.php");

else

header("Location: ./login.html");

?> 

 

 

<form action="validate.php" method="post">

<label for="userid">ID</label>

           <input type="text" name="userid" id="userid" />

<br />

<label for="password">Password</label>

<input type="password" name="password" id="password" />

<br />

<input type="submit" name="submit" value="Submit" />

</form> 

 

 

</body>

</html>

 

2. I want to know whether a PHP page should have an Hyperlink, so that for example, in a form, if the submit button is clicked, it can go to the PHP page.

 

Please i really need help.  I will be greatfull if someone can help me out
