Splashscreen that loads per visit - php

Question

I have built a webpage, splashcreen.html, that when someone loads index.php will automatically go to. But I wish to also have a button, return to index.php, that allows users to go back to the homepage. But if the person closes the browser, this entire process restarts.
So it goes:
Open browser, index.php
Redirect to splashcreen.html
user clicks button, return to index.php
navigate without redirect
User closes browser
reopen and start this whole process again.
Is this possible?
Thanks!

Answer 1

Save a cookie, or send a GET value:
Go Home!.

Answer 2

You could have your index.php as the splash screen. Then the user clicks the button, redirect to home.php which is the "real" homepage.
Then instead of Home links pointing to the root (which implies index.php, therefore splash screen), have them point to home.php instead.
So:
user opens yoursite.com and meets your splash screen
user clicks button to go to home.php
user navigates normally
once user closes and reopens browser to visit yoursite.com, well.. splash screen again!
If later on you get tired of the splash screen and plan not to use it anymore, you can use a simple .htaccess rule to redirect index.php requests to home.php

Answer 3

Yes, just set a cookie with JavaScript when the button is clicked in splashscreen.html, and have the php (or JS, whatever's redirecting) on index.php not rediect if the cookie is set. This is pretty easy, just search for it on Google.

Answer 4

You dont actually need to redirect to splash.html you could just use a session to store if its been seen or just continue to do your index.php
index.php
<?php
session_start();
if(!isset($_SESSION['splash'])){
//Show splash screen
ob_start();
include('./splash.html');
$contents = ob_get_contents();
ob_end_clean();
echo $contents;
$_SESSION['splash']=true;
die;
}
//Do normal index.php
?>
