if( isset($_GET['submit']) )
{
$val = htmlentities($_GET['val']);
$tmp = shell_exec("python /opt/lampp/htdocs/dashboard/IR/song.py .$val ");
echo $tmp;
}
?>
<h1 class="register-title">Songs by User-ID</h1>
<form class="register" action = "" method="get">
<input type="text" class="register-input" id="val" placeholder="No of Songs">
<input type="submit" name="submit" value="Retrieve" class="Retrieve-button">
</form>
