无法从jquery ajax向php发送数据？

I am trying to send data to PHP using JQuery ajax. However, I am only able to the send the first key=value to PHP, the second key=value echo as blank.

For example: 

functionName="+env works but not username="+username;

How can I pass multiple key value pair to PHP from JQuery AJAX?

Jquery AJAX

var envdata="functionName="+env+",username="+username;
alert(envdata);


if(action == 'R'){
  $.ajax({
type: "GET",
url: 'getdata.php',
data: envdata,
success: function(response) {
                $("#textarea_message").val(response);

}

getdata.php

$env = filter_input(INPUT_GET, 'functionName');
echo $env
$username = filter_input(INPUT_GET, 'username');
echo $username;

我正在尝试使用JQuery ajax将数据发送到PHP。 但是，我只能将第一个 key = value 发送到PHP，第二个 key = value echo作为空白。

例如： 

  functionName =“+ env工作但不是用户名=”+用户名; 
   
 
 
如何 我可以从JQuery AJAX向PHP传递多个键值对吗？ 
 
 
  Jquery AJAX   
 
 
  var envdata =  “functionName =”+ env +“，username =”+ username; 
alert（envdata）; 
 
 
if（action =='R'）{
 $ .ajax（{
type：“GET”，\  nurl：'getdata.php'，
data：envdata，
success：function（response）{
 $（“＃textarea_message”）。val（response）; 
 
} 
   
 
 
  getdata.php   
 
 
  $ env = filter_input（INPUT_GET，'functionName'）; 
echo $ env 
  $ username = filter_input（INPUT_GET，'username'）; 
echo $ username;

    You're building your data wrong. it's basically equivalent to a URL query string, which means you need to use & as the separator, not a ,:

    var envdata="functionName="+env+"&username="+username;
                                 ^---note the &

    commas mean nothing to PHP as far as url query arguments go, so your ,username=foo would become part of the functionname value.

    A simple var_dump($_GET) would show you exactly what PHP is seeing come in. Doing that should've been your first stop when you didn't get your expected data in the script.

    Read about JSON

    $(document).ready(function() {
$('#some_button').on('click', function() {
    var checks = new Array();
    $("input[name='ls_id']:checked").each(function() {checks.push($(this).val());});
    $.ajax({
                type: 'POST',
                url: "some url",
                dataType: 'json',
                cache: false,
                data: {checks: checks, func: 9},
                success: function(data) {
                }
            });
});

    });

    getdata:

    $json = json_decode($_POST['checks'], true);
        print_r ($json);
