Age verification with cookie in header

[Design75]

if( isset( $_SESSION['age_verification'] ) and $_SESSION['age_verification'] != true ) die( header('Location: http://www.google.com'   ); 

should be:

if( isset( $_SESSION['age_verification'] ) and $_SESSION['age_verification'] != true ) die( header('Location: http://www.google.com'   )); 

You missed a closing )

Thank you for the response Design75. I updated the code and I still receive a 500 internal error after the first instance of this code. I wonder if where I place the code on the index.php file matters. The template I am running is Winchester responsive. Currently I am placing the following at the top of index.php:

    <?php
session_start();
    if(! isset( $_SESSION['age_verification'] ) or $_SESSION['age_verification'] != true ) die( header("Location: checkage.php?url=http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]") );

    // session_destroy(); // uncomment to reset for testing and debugging.

?>

Here is the checkage.php file:

<?php

   
    // checkage.php
    session_start();

    // checkage.php
    if( isset( $_POST['yes'] ) )
    {
        $_SESSION['age_verification'] = true;

        if( isset( $_GET['url'] ) )
        {
            die( header('Location: ' . $_GET['url'] ) ); 
        } 
        else
        {
            die( header('Location: index.php') );
        }
    }
    elseif( isset( $_POST['no'] ) )
    {
        $_SESSION['age_verification'] = false;
    }

    // The below line will check if someone has already said no so you can show them a page which tells them to they are too young.
    if( isset( $_SESSION['age_verification'] ) and $_SESSION['age_verification'] != true ) die( header('Location: http://www.google.com'));

    ?>

    <form method="POST" >
    <fieldset>
    <legend>Are you over 18?</legend>
    <input type="submit" name="yes" value="Yes" /> <input type="submit" name="no" value="No" />
    </fieldset>
    </form>

On a side note, with all the code placed where it is, the form is not presented on a properly setup html page... There's no html, header, or body tags applied from what it looks like...

Also guessing that you don't want your webpage indexed? As how will an SE navigate the page under the current setup?

Hello mc12345678,

Attached is a copy of my index.php . I am not too proficient in PHP. I would like to have SE navigate the page if possible.

<?php
   
session_start(); 
    if(! isset( $_SESSION['age_verification'] ) or $_SESSION['age_verification'] != true ) die( header("Location: checkage.php?

url=http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]") ); 

    // session_destroy(); // uncomment to reset for testing and debugging.
