Hi guys. Need a little help adapting this php script. Basically I am helping a church update their website. They want a few pages to be password protected.

I found the following script which works does the job, except now I have been asked if it is possible to set up things so that within a browser session, the password is "remembered" so that people won't have to re-enter the password if the browse away from the protected page and then go back again.

This is a little out of my league as I am new to php so I was hoping someone here could help me add the required code.

Here is what I have so far:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
<title>Members Page</title>
<?php $password = "admin";?>

</head>

<body>
<div id="top">
	<div id="header"></div>
</div>
<div id="menu">
	<ul>
		<li><a href="#nogo">Home</a></li>
		<li><a href="#nogo">Sunday Services</a></li>
		<li><a href="#nogo">Activities</a></li>
		<li><a href="#nogo">Gallery</a></li>
		<li><a href="#nogo">Community</a></li>
		<li><a href="#nogo">Youth</a></li>
		<li><a href="#nogo">Letting / Room hire</a></li>
		<li><a href="#nogo">Contact</a></li>	
	</ul>
</div>
<div id="content">
	<div id="content-wrapper">
		<div id="left">
			<div class="inner-wrapper">
				<h2>Members Page</h2>
				<?php 
				if (isset($_POST["password"]) && ($_POST["password"]=="$password")) {
				?>
				<!-- START OF HIDDEN CONTENT -->
				
				  <p>Congratulations you have gained access to the Protected and Secret Area!</p>
				
				<!-- END -->
				<?php 
				}
				else
				{
				if (isset($_POST['password']) || $password == "") {
				  print "<h4>Incorrect Password</h4><h4>Please enter the correct password</h4>";}
				  print "<form method=\"post\" action=\"\"><p>Please enter your password for access<br />";
				  print "<input name=\"password\" type=\"password\" size=\"25\" maxlength=\"10\" /><input value=\"Login\" type=\"submit\" /></p></form>";
				}
				?>
			</div>
		</div>
		<div id="right">
			<div class="inner-wrapper"></div>
		</div>
		<div id="content-footer"></div>
	</div>
</div>
<div id="footer"></div>

</body>
</html>

Here is a link to the demo page as it is working now. LINK

Thanks
Cara

Sounds like maybe you want to set a cookie?
Session cookies will last the length of the browser session, or persistent/permanent cookies are stored for the next visit(s).

Something like this.
Once the user enters the correct username and password, use the info to set a session:

<?php
//get username and password from form
$username=$_POST['username'];
$password=$_POST['password'];

//get data from database
$sql=”SELECT * FROM logins WHERE username=’$username’ and password=’$password’”;
$result=mysql_query($sql);

//mysql num row is counting table row
$count=mysql_num_rows($result);
//if results match, then $count=1

if($count==1){
//register username and password, redirect to login_success.php
session_register(”username”);
session_register(”password”);
header(”location:password_protected_page.php”);
}
else{
echo ‘<a href=”login.php”>Access Denied. You have brought shame on your family, click here to go back</a>’;
}
?>

The on all susequent pages containing restricted content, use the following to filter the users out:

<?php
//check if session is registered, if not then redirect back to main page
session_start();
if(!session_is_registered(username)){
header(”location:login.php”);
}
//rest of the page goes here
?>

This works for me

That works on my localhost. Just added a small bit into your procedural coding
