Hello everyone,
I need a script ( PHP or JAVASCRIPT) that allow a page to be viewed ONCE PER DAY basing on visitor's IP address. Any help ?
Many thanks in advance.

You can do this in either Javascript or PHP.

JavaScript alone would have to rely on the use of a cookie with a 24 hour expiration date. the issue with this is all the user would have to do is clear their cookie and they would be able to view the page.

Using PHP you would have to store the IP address in someway whether it be a flat file or in a database. The latter being the preferred method for quicker retrieval. The catch to limiting a site
by IP is that there are computers that are networked that would externally appear to have the same IP. This would mean not just one persons computer gets locked out but the entire company gets locked out. For this reason it can be problematic to rely on IP.

This is one reason forcing a user to register is preferred that way you actually can determine who is viewing the site and lock it out by user. Still if they setup multiple user accounts they can bypass this. I am not sure of the best complete way to do what you are asking but those are the options and the pitfalls of each method.

PHP Code:

//Set a cookie with a 24 hour exp date such as this:

$one_day = 60 * 60 * 24 + time(); 
setcookie('smitten', "yes", $one_day); 

//Then use a code like this to test if it is set:

if(isset($_COOKIE['lastVisit'])){header('Location: REDIRECT_HERE);}else{} 

Sorry I dont know the tags to make it highlight.

Thanks Nico by the way there is an error in my code

This line:

PHP Code:

if(isset($_COOKIE['lastVisit'])){header('Location: REDIRECT_HERE);}else{} 

Should be

PHP Code:

if(isset($_COOKIE['smitten'])){header('Location: REDIRECT_HERE);}else{}

Create a database with this structure

table name: logs
column 1 name: ip
column 1 type: varchar(15)
column 2 name: time
column 2 type: int

and on the page you want to protect, use this

PHP Code:

<?php



mysql_connect('localhost', 'MYSQLUSERNAME', 'MYSQLPASSWORD');

mysql_select_db('MYSQLDATABASENAME');



mysql_query('DELETE FROM `logs` WHERE ' . (time() - 86400) . ' >= `time`');



if (filter_var($_SERVER['REMOTE_ADDR'], FILTER_VALIDATE_IP)) {

        $result = mysql_query('SELECT `time` FROM `logs` WHERE `ip` = "' . $_SERVER['REMOTE_ADDR'] . '"');

        if (mysql_num_rows($result) === 0) {

                mysql_query('INSERT INTO `logs` VALUES ("' . $_SERVER['REMOTE_ADDR'] . '", ' . time() . ')');



?>



<!-- display your html code here. if you need to use PHP, do it like this -->



<div id="blah">blah, this is some html but wait, I need <?php echo 'PHP!' ?>!</div>



<?php



        } else {

                exit('Sorry, you have already visited this page in the last 24 hours!');

        }

} else {

        exit;

}



?>

That should work

Remember, in a densely populated area, you may have many different visitors coming through the same IP address.

[ruteckycs]

Or different visitors on the same IP via a LAN, That is why I suggest the cookie method. Restrict them by computer.

Working Javascript method (cookie based)

Code:

  <script language ='javascript'>
   function createCookie(name,value,days) {
   	if (days) {
   		var date = new Date();
   		date.setTime(date.getTime()+(days*24*60*60*1000));
   		var expires = "; expires="+date.toGMTString();
   	}
   	else var expires = "";
   	document.cookie = name+"="+value+expires+"; path=/";
   }
   
   function readCookie(name) {
   	var nameEQ = name + "=";
   	var ca = document.cookie.split(';');
   	for(var i=0;i < ca.length;i++) {
   		var c = ca[i];
   		while (c.charAt(0)==' ') c = c.substring(1,c.length);
   		if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
   	}
   	return null;
   }

   /* Check the cookie and redirect if they have it set. */   
   
   sWhere = 'http://google.com';  // replace this with where you want them to be sent when they can't view page. 

   if(!readCookie('viewcheck')){
      createCookie('viewcheck',1,1);
   } else {
      window.location = sWhere;
   }
</script>
