How do I create a link that sends the user to another page which is then diverted to another page associated with the link?

How do I create a link that sends the user to another page which is then diverted to another page associated with the link?

I would like to create a list of html URLS that as any one of them is clicked, it sends the user to an intermediary page, which asks the user whether they agree to the terms and conditions. If they do they are diverted to that page corresponding to that link they clicked. Similary to this diagram. enter image description here

Link 1 ==> Intermediary Page ==> Page 1,
Link 2 ==> Intermediary Page ==> Page 2,
Link 3 ==> Intermediary Page ==> Page 3,
Link 4 ==> Intermediary Page ==> Page 4,
Link 5 ==> Intermediary Page ==> Page 5

I do not know what process it called. I intend to use HTML and PHP.

HTML

<a href="inter.php?target=1">Some page</a>
<a href="inter.php?target=2">Some page</a>
<a href="inter.php?target=something_else">Some page</a>

PHP: inter.php

<?php
session_start();
$link='#';
switch($_GET['target']) {
 case 1:
       $link = "http://nexttarget.com";
       break;
 case 2:
       $link = "http://nexttarget2.com";
       break;
 case "something_else":
       $link = "http://nexttarget3.com";
       break;
}
$_SESSION['prev_link'] = "http://source_url";
?>

<form action="<?php echo $link; ?>" method="post">
<p>Your T&C here</p>
<input type="checkbox" name="agree" value="agreed" />
<input type="submit" value="go" />
</form>

PHP: target.php

<?php
session_start();
if( !isset($_POST['agreed']) || $_POST['agreed'] != 'agreed' ){
 header("Location: ".$_SESSION['prev_link']);
 exit;
}
?>
Your target page content here

EDIT: Edited to show T&C page instead of directly redirecting.

EDIT 2: Now the intermediate page will redirect automatically upon agreeing/clicking the checkbox.

PHP: inter.php

<?php
session_start();

$link='#';
switch($_GET['target']) {
  case 1:
    $link = "http://nexttarget.com";
    break;

  case 2:
    $link = "http://nexttarget2.com";
    break;

  case "something_else":
    $link = "http://nexttarget3.com";
    break;
}
$_SESSION['prev_link'] = "http://source_url";
?>

<form action="<?php echo $link; ?>" method="post" id="tc_form" >
  <p>Your T&amp;C here</p>
  <input type="checkbox" name="agree" value="agreed" onclick="javascript: this.parentNode.submit();" id="check" />
  <label for="check">I agree to the T&amp;C.</label>
</form>

An approach that's used a lot goes like this:

intermediary-page.php?proceedTo=some/url/to-go-next.php

On the intermediary-page.html (or php or whatever) page you perform the necessary verifications and redirect the user to the url available in proceedTo GET variable.

After that, it depends on your requirements. Do you want security or ensure that the user has accepted the terms and conditions or whatever? Then you should perform additional verifications on each page like so:

Link 1 -> Page 1 (check if the user has accepted the terms already? no? then:) -> intermediary?proceedTo=page1 -> (ask the user to accept! accepted? then:) -> Page 1 (user has accepted the terms now? yes? then:) -> stay here...

The advantages of this approach are:

  1. You are pretty sure that even if a user has bypassed the intermediary page and went straight for the final destination - (s)he will get thrown back to the intermediary page (as if you were authenticating the user).
  2. You don't need to create links like href="intermediary.php?next=abc.php", instead just go with simple href="abc.php" which will handle redirection itself.

You can user GET variables in a URL. eg http://www.mysite.com/intermediary-page?page=page1

So this will link to the Intermediary page. Then on that page you will have a function that looks at the last part of the url page=page1. Then that function will then redirect the user to the correct page.

your HTML link:

<a href="/links.php?page=1">Link 1</a>
<a href="/links.php?page=2">Link 1</a>

your PHP code in links.php:

<?php

$page = !empty($_REQUEST['page']) ? $_REQUEST['page'] : null;

if (!empty($page)) {

    switch ($page) {

        case 1:
            header('Location: abc.php');
            break;

        case 2:
            header('Location: xyz.php');
            break;
    }
}

The other options is:

$pages[1] = 'abc.php';
$pages[2] = 'xyz.php';

header('Location: ' . $pages[$page]);

Note: Try to secure the $page variable, before using it.
