Ajax response from Zend frameword - php

Question

Recently, I've been trying to create an online CRM using jquery/php/xml-rpc and I've had an issue that I just can't seem to find the solution to.
I currently have an ajax request sending an element id to a php document that when opened on its own (as a direct url to the document) returns a response from the API server (either a Boolean or some error like 'wrong data').
However this doesn't come out to my page at all and I am not sure the data I am sending is even getting through to the php document.
This is my jquery code:
$('#SomeElement').on('click', function(){
var id = $('#ELEMENTID').attr('value');
$.ajax ({
type:'POST',
url: 'PHPfile.php',
dataType: 'json',
data: {id:id},
success: function(data) {
if(data.indexOf('YES') === -1){
$('.alert-success').show();
$('.alert-success').html(data);
/*setTimeout(function() {
$('.alert-success').fadeOut('slow');
location.reload();
}, 2000);*/
} else {
$('.alert-danger').show();
$('.alert-danger').html(data);
/*setTimeout(function() {
$('.alert-danger').fadeOut('slow');
location.reload();
}, 2000);*/
}
}
});
});
And this is my PHP code:
require 'init_autoloader.php';
Zend\Mvc\Application::init(require 'config/application.config.php')->run();
$q = mysqli_query($conn, "SELECT * FROM some db WHERE somekey = '$_POST[id]'");
$main = mysqli_fetch_assoc($q);
if($main['someentry'] !== '0') {
echo 'This is FALSE';
} else {
$r = mysqli_query($conn, "SELECT * FROM side_db WHERE side_id = '$_POST[id]'");
$p = mysqli_query($conn, "SELECT * FROM ext_db WHERE ext_id = '$_POST[id]'");
$m = mysqli_query($conn, "SELECT * FROM img_db WHERE img_id = '$_POST[id]'");
$side = mysqli_fetch_assoc($r);
$ext = mysqli_fetch_assoc($p);
if((int)$ext['gt'] === '0' || (int)$ext['gt'] === '1') {
$g = 'yes';
} else {
$g = 'no';
}
foreach($ext as $key => $value) {
if($key === 'somestring') {
continue;
}else if($value === '0' || $value === '1') {
$ext[$key] = 'no';
} else if($value === '2'){
$ext[$key] = 'yes';
}
}
foreach($main as $k => $v) {
if($v === '0' || $v === '1') {
$main[$k] = 'no';
} else if($v === '2'){
$main[$k] = 'yes';
}
}
require 'init_autoloader.php';
Zend\Mvc\Application::init(require 'config/application.config.php')->run();
$appkey = 'appkey';
$someid = id;
$something = 'something';
$else = 'else';
$divarray = Array
(
'HEAL' = Array(
[0] = "WARLOCK",
[1] = "PRIEST",
[2] = "ROGUE",
[3] = "WARRIOR",
[4] = "MAGE"
),
"someENTRY" = 'YES'
);
$oxClient = new \Zend\XmlRpc\Client('http://link-to-server.php');
$somenewrequest = $oxClient->call('class.OfAPI',array($appkey,$someid,$something,$else,$divarray));
$res = $oxClient->getLastResponse();
echo $res;
$client = new \Zend\XmlRpc\Client('http://link-to-server.php');
if($m !== FALSE) {
$j = 1;
while($img = mysqli_fetch_assoc($m)) {
$pather = str_replace('../',"",$img['img_path']);
$url = str_replace('www.', "", $_SERVER['HTTP_HOST']);
$imagedata = file_get_contents('OUR/FILE/PATH/OF/SERVER'.$url.'/'.$pather);
$base64 = base64_encode($imagedata);
$SOMEID = $res;
$image = $base64;
$client->call('CLASS.IMAGESOMETHING',array($appkey,$usr,$psw,$res,$image));
$j++;
}
}
$fin = mysqli_query($conn, "UPDATE our_db SET avalue = '1' WHERE somefield = '$_POST[id]'");
echo 'You succeeded in doing w/e';
}
Excluding all the small errors I might have done due to having to rewrite half of the code to protect sensitive information, I want to know what I can change so that I can see the responses pop up on the page where the ajax is run.
I tried JSON.encode on the $res but that didn't seem to solve anything. Is there something I am missing or something I can do differently to get the responses I need or even see if the ajax variable is getting through to the php document.
Either way I would be happy to know what I am doing wrong so I can improve and not have to run into the problem in the future.
Thanks in advance!

In your $.(ajax) please put id in quotes to make sure it is interpreted as field name:
data: {'id':id},
Use developer-tools of google chrome to inspect your POST-request going to the server. Here a very good intro:
