trying to have a pop up that is remembered and checked globally

**Baby Jai** · 03-18-2009 11:57 PM

if you view my topic here
http://www.webdeveloper.com/forum/sh...085#post990085

i am trying to have it where once they enter the SITE they have to agree they are 18 years of age or older, no matter what they do, if they click NO it remembers that, how would i make something like this on every page so there is no way of getting around it

Use a session variable. Have the yes link/button set a SESSION value and test for it on every page using an included file or function call.

oh could you help me with that, I dont know much about it

First put this on the page and see if session is auto started

Open a new file and add this code ( just this code) to the very top of the file (no spaces before)

PHP Code:


<?
$_SESSION['test']='testing';
echo $_SESSION['test'];
?>

Save it and visit it in a browser. If you dont see 'testing' then you need to add this

PHP Code:


<?
session_start();
$_SESSION['test']='testing';
echo $_SESSION['test'];
?>

Then you should see 'testing' and the SESSION is good. if you need to start the session the you need to do that on every page using SESSION variables.

Open a new file and add this code.

PHP Code:


<?
$kick_to="/index.php";
if(!isset($_SESSION['over18'])) header("Location: $kick_to");//kicks user to root folder index file. Change to anything you need 
?>

Save this file as kick.php remember the path to where the file is saved

Open a new file and add this code to the top of every page you want to protect.

PHP Code:


<?
include "/path/to/kick.php";//change to the real path
?>
<html>
<head>
etc, etc...

index.php is presumably your site's entry page and where I'm kicking users to. Here have the javascript that handles showing the pop up. I've used a simple confirm but ou could use a pop up, hidden div etc and submit a form that reloads the index.php page.

PHP Code:


<?
//unset($_SESSION['over18']);//uncomment to reset SESSION var
?>
<html>
<head>
<script type="text/javascript">
<!--
function agecheck(){
<?
if(@$_GET['ru18']=="yes")$_SESSION['over18']=1;
if(!isset($_SESSION['over18'])){
?>
    var r=confirm("Are you over 18? If yes click OK")
    if (r==true){
        document.location="<?=$_SERVER['SCRIPT_NAME']?>?ru18=yes";

    }else{
        alert('No pron for you!');
    }
<?
}
?>
}
//-->
</script>

</head>
<body onload="agecheck()">
<?
if(!isset($_SESSION['over18'])) exit;//no session var so stop displaying content.
?>
hello grown ups!
</body>
</html>

Back up your original index.php and save above code as index.php in your root folder.

Please be specific with any problems you have. There never too much details when posting a problem.

This script is untested, but it should work.

PHP Code:


<?
session_start();  // This line must be at the top of the document for sessions to work

function age_check() {

    if (!isset($_SESSION['age'])) {    // Check if the user have answered the question or not
    
        if (isset($_POST['over_18'])) {        // If the user said (s)he was over 18
        
            $_SESSION['age'] = "over";        // Set a session variable that can be accessed anywhere from the script
        
        }
        else if (isset($_POST['under_18'])) {    // If the user said (s)he was under 18
        
            $_SESSION['age'] = "under";
        
        }
        else {        // Show the user the form
            echo "<form name='age_check' method='post' action=''>";
            echo "Are you 18 years of age or older? ";
            echo "<input type='submit' value='Yes' name='over_18'> ";
            echo "<input type='submit' value='No' name='under_18'>";
            echo "</form>";
            exit;  // Exit after the form
        }
        
        $url = $_SERVER['PHP_SELF'].$_SERVER['QUERY_STRING'];   // Get the url of the current page
        header("Location: $url");    // Refresh the page
    }
}

age_check();   //  Call the function

// Lets see if the user is 18+ years old
if ($_SESSION['age'] == "over")
    echo "You are 18 years of age or older";
else
    echo "You are less than 18 years old";
?>

If you don't want to kick then to the index you could just do this.

Create the include with this code

PHP Code:


<?
if(@$_GET['ru18']=="yes")$_SESSION['over18']=1;
if(!isset($_SESSION['over18'])){
?>
    var r=confirm("Are you over 18? If yes click OK")
    if (r==true){
        document.location="<?=$_SERVER['SCRIPT_NAME']?>?ru18=yes";

    }else{
        alert('too young');
    }
<?
}

ANd include it on every page you want to protect like this

PHP Code:


<?
//unset($_SESSION['over18']);//uncomment to reset SESSION var
?>
<html>
<head>
<script type="text/javascript">
<!--
function agecheck(){
<?
include "/path/to/agecheck.php";
?>
}
//-->
</script>

</head>
<body onload="agecheck()">
<?
if(!isset($_SESSION['over18'])) exit;//no session so stop displaying content.
?>
hello grown ups!
</body>
</html>

and be sure to call the js function onload too.

Err, you have 2 solutions (3 now) and I went to great lengths to explain how to use it and mine has your requested pop up and also handles not displaying code to under 18s and determining if auto stat is set. Yet you chose the shorter version and ask how to use it?

I like helping people who like to learn but that just seems lazy to me.

**Baby Jai** · 03-19-2009 02:11 PM

**SyCo** · 03-19-2009 02:12 PM

Set what? Where do I say change a URL? If you don't know what you're doing and you change stuff I'm not surprised it's not working.

What?

Please re read it and follow the instructions more carefully.

**Baby Jai** · 03-19-2009 02:16 PM

ok i followed it to a T!

PHP Code:


<?

$kick_to="index.php";

if(!isset($_SESSION['over18'])) header("Location: $kick_to");//kicks user to root folder index file. Change to anything you need 

?>

that to me MEANS that i can change ANYTHING to i need, if you look at the code on the pages you will see it doesnt work, every link i go to after the main page goes to index.php because i inlcuded this on all the pages I wanted to protect, it works ok in IE but not in Firefox and in Opera

The session part i dont understand, im not that great with php, I mean i dont want it saying testing on every page
