Using AJAX to pass variable to PHP and retrieve those using AJAX again

Question

I want to pass values to a PHP script so i am using AJAX to pass those  and in the same function I am using another AJAX to retrieve those values    The problem is that the second AJAX is not retrieving any value from the PHP file  Why is this  How can I store the variable passed on to the PHP script so that the second AJAX can retrieve it    My code is as follows   AJAX CODE     document  ready function                 raaagh   click function                  ajax               url   ajax php     This is the current doc             type   POST               data    name  145                success  function data                   console log data                                         ajax               url  ajax php               data                 dataType  json               success function data1                   var y1 data1                  console log data1                                           PHP CODE    lt  php  userAnswer     POST  name        echo json encode  userAnswer         gt

No need to use second ajax function  you can get it back on success inside a function  another issue here is you don t know when the first ajax call finished  then  even if you use SESSION you may not get it within second AJAX call   SO  I recommend using one AJAX call and get the value with success   example  in first ajax call        ajax           url   ajax php     This is the current doc         type   POST           data    name  145            success  function data               console log data               alert data                 or if the data is JSON             var jdata   jQuery parseJSON data
