This code displays the Welcome modal window on page load on the Landing page, and also when the page is refreshed.

The Visitor only needs to see it once as they navigate the site and return back to the Landing page.

What's the code to have it viewed just once for the Visitor?

</noscript>
<script>
    $('#welcomeModal').modal('show');
	$("#file-3").fileinput({
		browseClass: "btn btn-warning  ",
		showUpload: true,
		showRemove: false,
		showCaption: false,
		
		fileType: "any"
	});
    $(".btn-warning").on('click', function() {
        if ($('#file-4').attr('disabled')) {
            $('#file-4').fileinput('enable');
        } else {
            $('#file-4').fileinput('disable');
        }
    });

	</script>
<noscript>

Use sessions, you need session_start() on every page where you may be calling the modal.

<?php
session_start(); // start a session
...
...
<script>
<?php
// if the session is not set then show the modal
if (!isset($_SESSION['modal'])){
    echo "$('#welcomeModal').modal('show');";
}
$_SESSION['modal']=1; // create the session
?>
...

Gary, can you explain the code.

So within the same browser session, the Visitor will return to the Landing page, but will not see the modal again? Which is the objective.

The Ultimate Checklist to Optimize Your Website

Websites are getting bigger and complicated by the day. Video, images, custom fonts are all great for showcasing your product/service. But the price to pay in terms of reduced page load times and ultimately, decreased sales, can lead to some difficult decisions about what to cut.

not see the modal again
Correct, in any visit they will only see it once

You can also use a cookie or local storage, this makes it a bit more complicated if you still want to show the modal on their next visit - so the session is the easiest way

You may want a longer-term memory of the cookie.  This article gives the general design pattern.  I think it could be adapted for a modal window, just as it is used for a "splash" page.

Gary, so with this approach, on their next visit the User will not see the modal?

1) What if they clear their browser history prior to visiting a second time?

2) Or visit with a different browser on thier second visit?

3) Or view in phone, tablet first time, second time?

PHP sessions are short-term storage.  They are (almost always) cookie-based, and cookies are device+browser specific.

1) What if they clear their browser history prior to visiting a second time?
If the client removes the cookie, the browser cannot send the cookie to the server, therefore the server has lost its "stateful" information and will not know that the client has visited before.

2) Or visit with a different browser on their second visit?
Each browser and each device has its own "cookie jar" and if the browser does not send the cookie with the request, the server will not receive the cookie and will not know that the client has visited before.

3) Or view in phone, tablet first time, second time?
Each device and each browser has its own "cookie jar" and if the browser does not send the cookie with the request, the server will not receive the cookie and will not know that the client has visited before.

4) Or just sits there doing nothing for a while?
PHP sessions have a "garbage collection" algorithm that causes PHP to clean up unused session data after a period of time.  It's a complicated algorithm, but you can research it on php.net to see when it may get invoked (some installation and configuration parameters are involved) and whether it's useful for your application design

5) Or closes the browser and then starts it up again?
PHP Session cookies are normally set with a lifetime of zero, meaning that they disappear when the browser is closed.  So if you're reliant on sessions, your client will lose the session cookie when they close the browser and when they reopen the browser and come back to your site the browser will not be able to send a cookie, hence they will not be able to renew a session.

There are some other long-term persistent client data stores that you may want to consider.  Browser implementation and human acceptance is uneven.

No, they will see the modal on the next visit
If they use a different browser or device then they will see it initially again.
