PHP - How To Access Symmetric Key?

Hi,

I want to control a variable (decide whether to track click if coming from a specific site oppose to hitting the final site (destination) directly.
For example:

www.portal.com - this will be a management site that will redirect viewers to the the final destination based on variable info - for exmample $a=123 or $a= 567 - which would come in as www.portal.com?a=123 or www.portal.com?a=567

Note: 123 would redirect to www.abc.com?a=123 and/or 567 would redirect to www.xyz.com?a=567 with said variable(s).
------

My question is this: What is the best method to authenticate (both on) www.abc.com and/or www.xyz.com that the referred viewer came from www.portal.com?
I know about the super globals (HTTP_REFERER) but want to know if there are other (more) secure method to manage this interaction between external domains /websites?

Any insight on this appreciated - thanks!

Array
(
    [game] => Array
        (
            [id] => 2011012593950636050
            [name] => Array
                (
                    [us] => Castlevania II: Belmont's Revenge
                    [uk] => Castlevania II: Belmont's Revenge
                )


echo print_r($this->game[0]['name']) but undefined offset error.

I don't want to loop through the first array either.

Thanks

I'm currently learning PHP and I think I have a decent grasp of procedural programming so I'm trying to set it up a little bit and get a hang of OOP. I'm finding it a little tough going but I am making progress, the syntax and coding of it is fine but I don't quite get some theory and the best way to use it yet. It's only my third day in but I have a question relating to access modifiers.

It's a simple one, but what is the point?

That may sound a bit narky but I keep hearing and reading that it's good programming convention but it's never really explained why. What am I missing?

I get how they work but I don't really get why to use them. I've even read that private should only be rarely used, if at all as it makes testing harder and it stops you from being able to extend your classes. I'm not against using them - I want to learn to program to the very best of my ability but I'm eager to learn what benefits it actually has. Is there a technical reason, for example?

Hi guys,

I am making a site where users upload files (like images, pdfs, etc) to the server.

My question is, how does Facebook handle file permissions, restricting access to files uploaded to their servers based on what a user sets?
Because I need to implement a similar thing and have no idea how to do it in a clean way.

I have had two thoughts on storing the files 1) in a DB or 2) in a folder out of the wwwroot, which would prevent access by anyone without knowing the path (or some such) but it is the more "real" permissions implementation I am stuck on.

I obviously would like to achieve this with PHP and MySQL(i).

Any help is much appreciated.

Cheers in advance.

I've got data in a mySql database which is updated daily. I would like to allow webmasters to place this data in a form of a widget on their websites provided they pay for access. If not payment comes through we should be able to block access.   Any suggestions how this project would be designed?

When I send values to the foreach they are not recorded in the array.

$x = $getProductID;
$_SESSION['pColors'] = array();

if(isset($_POST['pColors'])) {

    foreach($_POST['pColors'] as $colorKey => $RColors) {
        $_SESSION['pColors'][$colorKey] = $RColors;
    }
}

var_dump($_SESSION['pColors']);

Send date with AJAX:

                $('.addToCart').click(function(){
                    $.ajax({
                        url:""+realLink+"cart.php",
                        method:"POST",
                        data:{action:action,pColors:pColors},
                            success:function(data){
                               //alert(data);
                            }
                    });
                });

Hello.  Basically I have created a form that you fill in and an email gets sent to your in box and you have an access_level of 1.  Within this email there is one field.  A validation_id.  Now what im trying to do is when you click this link it opens the webpage and updates your access_level to 2.  I have wrote my query and array and i can see exactly which bit is wrong.

Its where i have

validation_id= $validation_id")

Now its not working and I can see the error.  Problem is im too new at this to understand why its wrong and how to fix it can anyone help?  Here is the rest of the code.  Also could you please explain?  I would really like to understand it before i move any further.
p.s.  I have already selected my database in the included file

      <? include('database_name');
session_start();


  $validation_id =$_GET['validation_id'];
  $FullRec__query=sprintf("SELECT * FROM Members WHERE validation_id= $validation_id"); 

  $FullRec = mysql_query($FullRec__query, $database name) or die(mysql_error());

  $FullRecArray = mysql_fetch_array($FullRec);

  $UdateAccessQuery = sprintf("UPDATE Members SET access_level = '2' WHERE validation_id = $validation_id");

  mysql_query($UdateAccessQuery, $database_name) or die(mysql_error());
 ?>

I have a file that an ajax function calls on my site, and I want to make sure only the right pages access it.

For example.

I have page called home (home.php) and on that page i have an ajax call, which calls a file called ajax.php.

I want to make sure that when ajax.php is being executed, it is being executed via an ajax call, which is coming from the home page.

is this possible?

How does a web server, with a database connect to the emails it receives?

How does the web server get the contents of the emails it receives so I can parse it?

Thanks

I am looking to save the user's access of an application.  For instance, when they log in, I create a record in the "track_login" table which includes information such as the requesting IP, the user's ID, the date, (not the user's password), etc.  And then for every page they visit, I store a record in the "track_page_viewed" table which includes a FK to the "track_login" table and also includes additional information about their request.   Both the track_login and track_page_viewed tables are currently in the same database as used by the primary application.   So far, so good.   Next, I want to start tracking when a user does special tasks such as when they forget their password and request that a new one be emailed to them. Or maybe when they attempt to login with an invalid username and password.  Currently, I just included another table called "track_special" which includes the data, the type of special request, etc.   Now, I am thinking of adding three other things to track: General PHP errors MySQL errors Try/Catch errors which I did not expect to happen One option is just to add these to my "track_special" table or maybe make one or three new tables in the same database.   But is this a good idea?  If I have a SQL error, do I really want to store the error in the same database?  Maybe I should use a separate database called "myTrackerDB", and include all the above tables in that database?  Or maybe I should just write the data to a flat file, and parse the file on a regular basis, and then store the information in the database?   Please provide any recommendations, guidance, suggestions, criticism, etc.  Thank you

I am trying in vain to access the numbers in the "sims" array using the code below, I have tried various numbers of nested foreach loops but get errors every time, can anyone help point me in the correct direction please.   Thanks   Gordon

$stock = (array(1)

		{ [0]=> array(2) 
			{ ["operator"]=> string(3) "ECL" 
				["sims"]=> array(51)

} } } )


foreach ($stock as $key1 => $item1)
            { 
                foreach($item1 as $key2 => $item2)
                { 
                		foreach($item2 as $key => $value)
                		{
                    		echo $value[sims] . "</br>";
                		}
            	}

Only thing I really miss from PHP is "internal" access modifier. Before I was making libraries and extensions in C# (like game frameworks, Tiled implementations, GUI loaders). Now, when I am working on my own PHP framework, I really miss internal, I was using it a lot in C#. Is internal planned to be added in PHP 7 or is it already in PHP 5.6 or it will never be added?

I am using WAMP server for my PHP Server and am trying to connect to an Access Database with the extension of accdb, but I keep getting the error "could not find driver". Here is the code I'm trying to run:   $dbName = $_SERVER["DOCUMENT_ROOT"]."/Ridley/RLCompRepair.accdb"; if (!file_exists($dbName)) {      die("Could not find database file."); } try {      $db = new PDO("odbc:Driver={MS Access Database (*.mdb, *.accdb)};Dbq=$dbName"); } catch (PDOException $e) {      echo "Error: ".$e->getMessage(); }   I have enabled the php_pdo_odbc extension, so I'm pretty sure this is not the problem. Could someone please let me know what is wrong?   Chris

 I am trying to get around the login on one page on my server that my developer did but, now has decided to disappear. I know a little C++ but hardly no PHP.
Any one may view the thumbs but, when you click on the thumbnail you will be prompted to login. Which is fine what, I want, except for one page. I separated out the videos that I wanted to be free, created a new database table for them and wrote a function to lay out the thumbs to the screen but, you still get prompted to login.

I thought there was a way to do it using $_SESSION or $_SERVER but, I just can't seem to get it to work.

Any help would be appreciated. I've just spent to much time on this problem and I've got so any more to fix.

Thanks grggfks

I am trying to figure out how to setup cookies so that you can only view certain pages a few times, but then it will take you to a registration page. And if you hit refresh or back it will take you to a second registration page.

I want to be able to allow a new visitor access for a limited time, but then force registration. Does anyone know how to accomplish this?
