I have a ajax script to a folderwatcher. The folderwatcher will return $dir. The page with the ajax script will later on get the dir and then echo it out later in the php code.
How to i get the variable so i can just echo it out?
Ajax page:
<!DOCTYPE html>
<head>
<script type="text/javascript">
$(document).ready(function(){
setInterval(function(){
//code goes here that will be run every 5 seconds.
$.ajax({
type: "POST",
url: "checkfolder.php",
success: function(result) {
//something that will get the varaible?
}
});
}, 5000);
});
</script>
</head>
<body>
<?php
echo $dir;
?>
</body>
</html>
The folder watcher, that returns the right dir:
