Showing DIV Splash Just Once Per IP/Visit.

PentaGram

Hello everyone!

I have this code:

<DIV id="Intro" class="Intro">
...
<A href="#" class="ComeIn" style="COLOR: #FFF">Enter on the website</A>
</DIV>
<SCRIPT>
$('.ComeIn').click(function()
{
$(this).parent('#Intro').fadeOut(1000);
});
</SCRIPT>

I need the DIV "Intro" to be shown just once per user's visit or per IP, whichever is better... I just do not want it to be shown every time the visitor reloads the page or restoring it after closing it. The DIV Splash and the main page are the same file.

Probably the simplest way PHP-wise would be to use a session variable, something like...

<?php
session_start();
?>
<!-- first part of the page -->
<?php if(empty($_SESSION['div_shown'])) { ?>
<div>The once-only DIV here</div>
<?php  $_SESSION['div_shown'] = true; } ?>
<!-- rest of page -->

That might indicate a cookie instead of a session var ...

I'd be careful with IP addresses as well because some ISP's these days will serve new IP addresses for each page the user visits. Especially users on mobile hot spots.

One other thought, you could also use the localStorage Object to indicate if the user has seen the splash animation.

Or the document's "cookie" property.

This part doesn’t work.

How does it not work?

I put the <?php
session_start();
?> at the very top of the page and when I load it, it shows that it has an error on the line #2, that is "session_start();".

Yes, but what kind of error???

What is the error?

Incidentally, no spaces, nor whitespace of any kind, can be above [man]session_start/man.

This would include an errant Byte-Order-Mark placed there by well-meaning but misconfigured IDE's or editors.
