PLAYING A SOUND FILE ONCE A SESSION - Dec 31st, 2012


I recently had a request to play a greeting message only the first time a visitor accessed my client’s site. My client
was OK with the idea that the “first time” could be defined by opening the visitor’s browser. I wanted to avoid
using Javascript and stick with PHP, so here’s what I found. Hope it proves useful.

This code gets placed a the very head of your page, before the “require once” code.



<?php setcookie("firsttime","no") ?>



And this code gets placed right after your <body> tag



<?php
$firsttime = $_COOKIE[firsttime];
if (@$firsttime != "no") { echo "<embed src='http://www.yoursite.com/yourgreeting.mp3' width=0 height=0 />"; }
?>



The width and height are set to “0" so that the player is invisible on the page.

But what if you wanted to play the sound once a day instead of once a session? The answer is in the next recipe.
