Question

I have four textboxes and when you click on the add one button it will add up another set of textboxes. My problem is how can i pass the json data to the action form. Here is my code:
$("#test").click(function(){
var array = $('.experience').map(function() {
var obj = {};
$(this).next().addBack().find('input:text').each(function() {
obj[this.id] = this.value;
});
return obj;
}).get();
$('#json').text(JSON.stringify(array, null, 2));
});
and my form action
<form action="<?php echo base_url().'resume/update'?>" method="post" id="send_form">
<!-- Experience Start -->
<div class="row">
<div class="col-sm-12">
<p> </p>
<h2>Experience</h2>

Use json_encode and json_decode function example in ref link,
json_encode($arr);
var_dump(json_decode($json));
http://php.net/manual/en/function.json-encode.php
var_dump(json_decode($json, true));
