Jquery Duplicate Fields Form Submit with PHP.

How to submit jquery duplicate/clone field values to form with PHP. It's very basic level code, I had implemented this using relCopy.js jquery plugin to duplicating the existing field. I hope it's useful for you. Thanks!

Javascript Code
Here input text name hobby[] is array. 

<script type="text/javascript" src="http://ajax.googleapis.com/
ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="reCopy.js"></script>
<script type="text/javascript">
$(function(){
var removeLink = ' <a class="remove" href="#" onclick="$(this).parent().slideUp(function(){ $(this).remove() }); return false">remove</a>';

$('a.add').relCopy({ append: removeLink}); 
});
</script>

//HTML code

<form method="post" action="clonesubmit.php">

<p class="clone"> <input type="text" name="hobby[]" class='input'/></p>

<p><a href="#" class="add" rel=".clone">Add More</a></p>

<input type="submit" value=" Submit " />

</form>

clonesubmit.php
Contains simple PHP Code that extracting array hobby[] values.

<?php

if($_POST['hobby'])
{
$array=$_POST['hobby'];
foreach($array as $hobby)
{

if(strlen($hobby)>0)
{
$sql=mysql_query("insert into hobbies(hobby)values('$hobby')");
}

}
}

?>
