PHP - Unique Visitor Check

I have lists of links in different pages. I want to add an option for the visitors to add favorite ones to a list (like add to cart in shopping sites), and finally see the links selected in a page. This is based on the visitor's browser cookies.

What is the simple way to do this (without database). Actually I need a function to save the items in the browser cookies and then retrieve them.

For debug purposes, I want to see all (each and every possible) variables from a website visitor, e.g.
• their user agent (e.g. cURL)
• the reqest string they used (e.g. "https://example.com/product.php?sku=12345")
• their IP address
• and everything else I haven't thought of

I know how to save the info in a database, I might even have the info emailed to myself, I just can't remember the "one-liner" I used to use to capture this info.

Thank you in advance!

 

Hi, didnt know how to add this to the repository so can an admin move this please.

this updated version will tell you still when you recieve a visitor but to identify who i have included so that it tracks the ip and tells you when its you!!!

<?php
// Script to email you when Google refers traffic to your site.
$name=""; // add your name here
$email_address=""; // add your email address here

$keywords="";
$referrer=$_SERVER['HTTP_REFERER'];

$known_ips = array(
    '01.01.01.01' => 'from the computer your are at now!',
    // etc.
);

$ip = $_SERVER['REMOTE_ADDR'];

if (array_key_exists($ip, $known_ips))
{
    $ip = $known_ips[$ip];
    // you may want to use a different var name here now?
}



if( (stristr($referrer, "google")) && (stristr($referrer, "search")) ) {

   parse_str($referrer, $output);
   $keywords=$output['q'];

   $email_message="A visitor just arrived to the website after searching for '$keywords', Their IP address is '$ip'. ($referrer)";

   mail ("$email_address","Google referred a visitor","$email_message");
  
}
?>


hope it all works... give it a try and let me know.

not sure what to think of this.  my code is:

$time = date("H:i:s", strtotime("+19 hours"));

	mysqli_report(MYSQLI_REPORT_ERROR|MYSQLI_REPORT_STRICT);
	$conn = new mysqli($dbHost, $dbUsername, $dbPassword, $dbName);

	$stmt = $conn->prepare("INSERT INTO tblTraffic (ip, host, page, date, time) 
						  	VALUES (?, ?, ?, ?, ?)");
	$stmt->bind_param("sssss", $ip, $host, $page, $date, $time);

what I get is in the attached image.  as you can see, it returns correct and incorrect values for the same ISP/IP address, but it returns correct values for a google bot.  In the past I was using:

date("H:i:s");

....and I was seeing the same results.  e.g. - some IP addresses were producing both correct returns and incorrect returns.  this correct/incorrect mix was also happening with various google bot /yandex / msn domains as well.  what is up with this guys?

I want to show different content to different users from different states. So, if a visitor is visiting the website from California, I want to show California content. Likewise, if a user is visiting from any other State (say NY, Chicago, or anywhere), I want to show content relating to that State. Any suggestions?

Thanks.

Hello PHP freaks,   my codes dont allow me to log-in to Student Home with unique id. It says "Invalid Login or Password" this is my form

<tr bgcolor="#E1E1E1" class="stylesmall">
              <td width="35%" align="left" class="style7 style1">Learner Id : </td>
                <td width="65%" align="left"><input name="learner_id" type="text" id="learner_id" action="Student_Home.php" method="post"></td>

Hey everyone. I have been working on a cart for my site and I've reached an impasse. I coded up the cart, the add to cart, the delete from cart and the subtract from cart. Problem is I now see a need to put an image for everything that is added to the cart. I think i have devised a way to do it with frames, the left frame being the cart and the main frame is purely for the images. I am having trouble getting the code right between the two pages to work. I need a picture on the right of every item added to the cart. Here is the url for the cart: http://www.theblack44s.com/Merchant%20pages/index3.php

I know this kind of thing can get extensive and I don't mean to take up any more of your time than necessary so if there are any suggestions or ideas of where I can find this information to learn it that would be just as good. Hey thanks for your time!

Hi i'm making a new website based on PHP. I bumped on a problem now...

The problem is that I have a loop where i get all records out of my sql database and get them into a form. Every record has a differend form with a button to. Every button then has a unique ID.

Now i tried everyting i could think of to get the value out of a button when a button is clicked. But nothing worked... here is the part of the code where everything is for the form and the POST.

Code: [Select]
while($record = mysql_fetch_object($result)){
$id = $record->id;
echo"<form action='home.php' method='post'>";
echo"<b>name:</b>".$record->name." <b>Price: </b>".$record->price."";
echo'<input type="hidden" name="id" value='.$id.'>';
echo"<input type='submit' value='Buy' /><br />";
echo"</form>";
}

if($_POST) {
$ID = intval($_POST['id']);
$query1 = "SELECT price FROM items WHERE id = ".$ID."";
$result1 = mysql_query($query1);
list($cost) = mysql_fetch_row($result1);
$gold = getStat('gc',$userID);
if($gold > $cost) {
setStat('gc',$userID,($gold - $cost));
$queryw = "INSERT INTO users_inventory(item_id,user_id, quantity) VALUES ('".$ID."','".$userID."','1')";
$resultw = mysql_query($queryw);
} else {
echo"You can't afford this weapons.";
}
}

The only thing that doesn't seem to work is this part

Code: [Select]
$ID = intval($_POST['id']);
is always gives me this error:

Notice: Undefined index: id in shop.php on line 26


Please help me out here i have no idea what to do from here on...

Need a bit of help with some php and a few kind members helped me in the past.

My code is:
$query = "SELECT names FROM table WHERE type='$type'";
$result = mysql_query($query) or die(mysql_error());

while($row = mysql_fetch_array($result)) { 
foreach(unserialize($row['names']) as $key => $value){ 
echo $value . '<br />'; 
} 
}

Basically, a field on my table is called names. The information in this field is serialized (so many names are together in a single field, for a single row).

I want to be able to search the whole table (where type='$type' - so many rows) for all names and then show unique names only.

My code above unserializes the names from each field and then lists them, but doesn't deal with any duplicates (which I need removing).

I have looked at functions like "unique_array()", and have tried using it in different places but it isn't doing the job.

Any help appreciated.

Hey guys. I need to know how to get a time that is constant. What I want to achieve:
I need to make a clock on my website showing only one time (HH:MM:SS), wherever the page is requested from.
And I need to use this "time" in calculations, like finding the time difference between two time values stored in my MYSQL Databases.
I hope that I am clear with my question.
Thanks for any help in advance! 

hi, im trying to create a website and only now started thinking about the security part(noob mistake). say for example i have home.php page and an index.php page. index.php is where users would sign up/log in. the login and sign up processes are all done but i was thinking of creating a unique id of some sort for when the user logs in. or something like this site (forum.phpfreaks) when we sign in, you are signed but the url stays the same = forums.phpfreaks.com. like if we were signed out we will be permanantly signed out and typing in forums.phpfreaks.com would just land us at the main page where we need to sign in.  right now ,my home.php can be accessed with or without logging in even with sessions.   hope im making sense, thanks in advanced!    **haha that rhymed.    i tried adding:   <?php echo $_SERVER[PHP_SELF] . '?name=' . $userData['name'];?> in the index.php:

<?php
ob_start();
session_start();
 
if(isset($_POST['login']))
{
	$email = $_POST['email'];
	$password = $_POST['pass'];
	 
	 require "connection.php";
	 
	$emails = mysqli_real_escape_string($con, $email);
	$query = "SELECT id, name, email, password, salt FROM users WHERE email = '$emails';";
	 
	$result = mysqli_query($con, $query);
	 
	if(mysqli_num_rows($result) == 0) // User not found. So, redirect to login_form again.
	{
		echo "<script>alert(\"User does not exist!\")</script>";
	}
	 
	$userData = mysqli_fetch_array($result, MYSQLI_ASSOC);
	$hash = hash('sha256', $userData['salt'] . hash('sha256', $password) );
	 
	if($hash != $userData['password'])
	{
		echo "<script>alert(\"Incorrect Password!\")</script>";
	}else{ 
		session_regenerate_id();
		$_SESSION['sess_user_id'] = $userData['id'];
		$_SESSION['sess_name'] = $userData['name'];
		session_write_close();
		header('Location: home.php?user=');
	}
}
ob_flush();
?>
<!DOCTYPE html>
<form name="login" method="post" action="<?php echo $_SERVER[PHP_SELF] . '?name=' . $userData['name'];?>">

but i got access forbidden!     
Edited by noobdood, 19 May 2014 - 10:05 PM.

i have table in my db that has rows of dates, for example...

      id       |                 date                  |                created           |        display     |     group         |
      1        |     2011-05-24 00:00:00     |  2011-05-24 20:00:00    |          Y           |         20          |
      2        |     2011-05-24 00:00:00     |  2011-05-24 22:00:00    |          N           |         20         |
      3        |     2011-05-26 00:00:00     |  2011-05-26 22:00:00    |          N           |         20          |
      4        |     2011-05-27 00:00:00     |  2011-05-26 22:00:00    |          N           |         20          |
      5        |     2011-05-27 00:00:00     |  2011-05-30 22:00:00    |          N           |         20          |

Now i'm trying to make sure that each group has no duplicate dates. If they do delete all but the newest. So in this case, after the code ran, it would have deleted row 2 and row 5 because they both have duplicate dates and they're the oldest of those particular duplicates. I posted in the PHP board and not the MySQL board because it's the logic i can't figure out. I believe array_unique() would come in handy but i can't wrap my head around how to use it to do what i want.

what is the easiest way to get unqiue sub arrays based on date from within my larger array?  here is what i mean in detail.  I have an array that outputs this...

Code: [Select]

 [0] => Array
        (
            [date] => 2010-11-02
            [time] => 7:00 p.m.
            [location] => Illinois
            [team1] =>
            [team1sc] =>
            [team2] =>
            [team2sc] =>
            [winner] => Illinois
        )

    [1] => Array
        (
            [date] => 2010-11-02
            [time] => 7:15 p.m.
            [location] => Purdue
            [team1] => University of Indianapolis
            [team1sc] => 59
            [team2] => Purdue
            [team2sc] => 82
            [winner] => Purdue
        )

    [2] => Array
        (
            [date] => 2010-11-06
            [time] => 3:05 p.m.
            [location] => Southern Illinois
            [team1] => University of Indianapolis
            [team1sc] => 58
            [team2] => Southern Illinois
            [team2sc] => 65
            [winner] => Southern Illinois
        )


I don't need value [ 1 ] because value [ 0 ] already has the same date!  My goal is to get a list of all the unique [date]s from this entire multidemonsional array. (FYI - I know I will be loosing blocks of arrays that have duplicate dates - THATS OK).  But it's a bit of a struggle for me unique array sections out of this...any help or advice would be great!

thanks!

I have a foreach parsing as
foreach ($posttags as $tag) {
$test = $tag->name;
$pattern = "/something/";
if(preg_match($pattern, $test)) {
$test2 = "$test is $test";
echo $test2;
}
}


I selected those containing a given word, but I do not know how to remove duplicates to have uniqueness. I was unable to use array_unique, as I am within a foreach loop.
