Hello, the functions are called in the XHR (status 200) but dont return anything as it should,. Even when i put an echo it doesnt return the echo. The path is correct



function userDetails(uid,apiBaseUrl,baseUrl,public_username,msgID,groupID)
    var encodedata=JSON.stringify({"uid": uid,"public_username":public_username,"msgID":msgID});
    var url;

    ajaxPost(url,encodedata, function(data) {

         some code....

When i put an alert before ajaxPost(url,encodedata, function(data) it alerts, if i put it after this line it DOESNT


function publicUserDetailsTest() {
  echo 'xxxx';

Your post doesn't make a lot of sense. What functions don't return anything? Where is ajaxPost defined? Does your API call actually work? Try accessing your API via another program like Postman or HTTPie.

Every single function doesnt return
I call a js file that contains this to call the ajaxPost

function ajaxPost(url, encodedata, success)
data :encodedata,
contentType: 'application/json',
beforeSend :function(data) 

success.call(this, data);

API call? You mean if the path is correct? I dont hav anything on the php function just an echo xxx;

Ok, so if you run this with your browser's developer tools open, what errors do you see in the console?

Nothing not one error or even a warning...

I think that the problem is that it never reaches the php functions. Otherwise it would returt the response right?


/ i am getting a 304 status on some of the files that i call Why is that

Like I said, access your API (even if it is only one function that returns {"hello": "world"}) using something less complicated. The tools I mention above are a good start. When you know that is working correctly and your url param is right, your server is listening on the right port etc, then integrate your JS.

I am getting nothing on Postman too. Response nothing. What should i do?

Hard to tell what's going on without knowing what your server is doing and that you're sending requests to the port it's listening on.

Here's what I'd do, substitute my Ruby for your PHP. First, create a standalone, super-simple API. Here's an example

require 'sinatra'
require 'json'

# world's simplest API
get '/hello' do
  {hello: "world"}.to_json

Now, when I run that file in Ruby, it tells me where it's listening.

== Sinatra (v2.0.0) has taken the stage on 4567 for development with backup from Puma

Finally, I just need to make a sensible request:

http get localhost:4567/hello

And here's the response.

HTTP/1.1 200 OK
Connection: Keep-Alive
Content-Length: 17
Content-Type: application/json
Date: Sun, 27 Aug 2017 17:22:05 GMT
Server: WEBrick/1.3.1 (Ruby/2.4.1/2017-03-22)
X-Content-Type-Options: nosniff

    "hello": "world"

Now, the browser hasn't been involved at all. Everything's simple and visible. If something goes wrong I'll get the feedback right in my terminal window. PHP supports this approach too.

i am getting an error "/hello"' (T_CONSTANT_ENCAPSED_STRING) in your code on line 5

function publicUserDetailsTest() {
  require 'sinatra';
    require 'json';
    # world's simplest API
    get "/hello" do
      {hello: "world"}.to_json

The code I provided is in an entirely different language, you can't just paste Ruby into PHP!

Maybe ignore JavaScript for a while and learn PHP first.
