Store clicks on each button separately in json - php

Question

I am using jquery, php and json to store and update the clicks on a single download button. It's working flawlessly but now I need to be able to store and update the clicks from multiple download buttons and display them individually.
Can you guys give me a hand with this?
What I have so far is:
jQuery:
$('.download').click(function(event) {
event.preventDefault();
ga('send', 'event', 'Button', 'Clicks', 'Downloads');
var redirectUrl = $(this).attr('href');
$.ajax({
url: "downloads.php",
success: function(response) {
if (response = 'success') {
// The counter file has been updated in the background, but we should update the results on screen to tell the user
var count = $('.small').html();
$('.small').html(parseFloat(count) + 1);
// Then redirect so that file can download
$("#cover").fadeIn(600);
$("body").addClass("hidescroll");
window.location.href = "download/imagins_._ro_free_files_format_icons.rar";
}
}
});
return true;
});
$.ajax({
url: "get-downloads.php",
success: function(data) {
var data = JSON.stringify(data, null, 4);
var data = $.parseJSON(data);
$('.small').html(data.count);
}
});
downloads.php
<?php
$file = "downloads.json";
$json = json_decode(file_get_contents($file), true);
$json['count'] = $json['count'] + 1;
file_put_contents($file, json_encode($json));
echo 'success';
?>
get-downloads.php
<?php
$file = "downloads.json";
$json = json_decode(file_get_contents($file), true);
header('Content-Type: application/json');
echo json_encode($json);
?>
and the downloads.json
{"count":174}

try like this
for example for 3 button
<input type='button' name='btn1' class='download'/>
<input type='button' name='btn2' class='download'/>
<input type='button' name='btn3' class='download'/>
send name of button to server and show count in different .smallbtn1،.smallbtn2،.smallbtn3
$('.download').click(function(event) {
event.preventDefault();
ga('send', 'event', 'Button', 'Clicks', 'Downloads');
var redirectUrl = $(this).attr('href');
//get name of button
var name= $(this).prop('name');
//==================
$.ajax({
url: "downloads.php",
data:{buttonName:name},
method: "POST",
success: function(response) {
if (response = 'success') {
//get count download
$.ajax({
url: "downloadsCount.php",
data:{buttonName:name},
method: "POST",
success: function(response){
$('.small'+name).html(response);
$("#cover").fadeIn(600);
$("body").addClass("hidescroll");
window.location.href = "download/imagins_._ro_free_files_format_icons.rar";
}
});
//===================
}
}
});
return true;
});
in downloads.php open json file
<?php
$buttonName=$_POST["buttonName"];
$file = "downloads.json";
$json = json_decode(file_get_contents($file), true);
$json['count'.$buttonName] = $json['count'.$buttonName] + 1;
file_put_contents($file, json_encode($json));
echo 'success';
?>
downloadsCount.php
<?php
$buttonName=$_POST["buttonName"];
$file = "downloads.json";
$json = json_decode(file_get_contents($file), true);
echo $json['count'.$buttonName] ;
?>
downloads.json
{"countbtn1":0,"countbtn2":0,"countbtn3":0}
this is my test and working for me
