jquery - How to fetch dynamically generated input fields value in php? - Stack Overflow

You inputs must be array [], otherwise you will not be able to receive them as array fieldA[]

Your jQuery should be like this:

$(document).ready(function(){
var $i = 1;
$('body').on('click','#this
#$_post['fielda'][$i] #name='fieldb["+$i+"]' #[fieldb] #$_post['fieldb'][$i] #inputs
