While receiving data on PHP file code is like -
print_r($_POST);
echo $name = $_REQUEST['name'];
I am getting null array
How to get the value while posting ? Here is the headers I used
use x-www-form-urlencoded while posting data.Then
echo json_encode($_POST);//prints into json format
Try it will works.
NOTE: By default, the $http service will transform the outgoing request by serializing the data as JSON and then posting it with the content- type, "application/json". When we want to post the value as a FORM post, we need to change the serialization algorithm and post the data with the content-type, "application/x-www-form-urlencoded".

How can I read content of Request Payload (POST) using PHP?
I´m using a Angular aplication to send the POST.
I've tried with: $_POST, $_FILES and file_get_contents('php://input') ...
None worked.
If you need view x-www-form-urlencoded post data, just use
print_r($_POST);
If you need view json post data, use this
$data=json_decode(file_get_contents('php://input'),1);
print_r($data);
Try:
$payload = file_get_contents('php://input');
I have this simple code
<?php
$json = array("status" => $_POST['name']);
header('Content-type: application/json');
echo json_encode($json);
?>
and when i send POST data with Advanced REST cliend, allways have an empty $_POST table.
You are using wrong transport method. If you want to read POST data in $_POST array you have to send it either as multipart or www form urlencoded.
To read the request body you have to use following code:
$postdata = file_get_contents("php://input");
Then you can parse the JSON and transform it to object.
If you want to read the data from the request using $_POST array you need to set Content-Type header to application/x-www-form-urlencoded and send the data as:
param-name=param+value
(note that it is url encoded).
I use Postman (the Chrome app) to send POST data to a URL but the POST data are never received by the PHP file, no matter how I change the content-type before sending. Is there a server setting on Apache that stops post data from external sources?
This is the URL:
http://friendesque.com/arranged/handler.php
And this is the content of the handler.php file:
<?php
echo("Inside file");
echo("JSON:");
$json = file_get_contents('php://input');
echo($json);
echo("POST:");
print_r($_POST);
echo("GET:");
print_r($_GET);
?>
In order for data to be available in $_POST array, the following conditions should be met:
Request must be sent with POST HTTP method
Content-Type header must be set to application/x-www-form-urlencoded
Request payload (body) must be in the form of URL-encoded parameters, e.g.
param1=a¶m2=b
I sent to your URL a request that meets those 3 conditions and got my data available in $_POST array.
Use file name like /index.php . It will work !!
I'm just trying to send a POST request with JS to server. But server has empty $_POST array. I could use HTTP_RAW_POST_DATA, but it'll be deprecated in PHP 5.6. Could I have posted data in my $_POST array?
Environment: Chrome, apache2, PHP, AngularJS (I'm using $http.post function).

The POST data must be in query string or multipart/form-data format to get decoded properly. Your data seems to be JSON, so you have to decode it by yourself:
$_POST = json_decode(file_get_contents('php://input'), true);
$_POST is populated by a request that is of type form-urlencoded or multipart/form-data. Typically it looks like:
foo=bar&ipsum=lorm
So kinda like a GET request.
Since you're posting JSON directly (which is awesome!) you can use:
$request_payload = file_get_contents("php://input");
See the docs for more info.
See by default, jQuery transmits data using Content-Type: x-www-form-urlencoded and the familiar foo=bar&baz=moe serialization. AngularJS, however, transmits data using Content-Type: application/json and { "foo": "bar", "baz": "moe" } JSON serialization, which unfortunately some Web server languages—notably PHP—do not unserialize natively.
so you can do this when you define your angular module:
angular.module('MyModule', [], function($httpProvider) {
// Use x-www-form-urlencoded Content-Type
$httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8';
});

looks like json data posting directly without any variable try with
$request = file_get_contents('php://input');
print_r($request);
or use a variable on posting data like
data{'myvar': data}
and will get on POST data like
print_r($_POST['myvar']);
Hi i am having problems with an XHR post request.
in javascript:
self.xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
self.xhr.setRequestHeader("Method", "POST " + url + " HTTP/1.1");
In firebug:
Parametersapplication/x-www-form-urlencoded
{"u":"andrepadez","m":"\n...
JSON
m
"sfdsfsdfdsfdsf"
u
"andrepadez"
Source
{"u":"andrepadez","m":"\nsfdsfsdfdsfdsf"}
In .NET, I post this to an .ASHX, and in the ProcessRequest i do:
StreamReader sr = new StreamReader(context.Request.InputStream, context.Request.ContentEncoding);
javaScriptSerializer.Deserialize<MyClass>(message);
and I have no problems.
I don't know how to get the data in PHP, either $_POST and $_REQUEST are empty arrays.
Any help please?
thanks
You've not set a field name for the data being sent. PHP requires data coming in via POST to be in a fieldname=value format. _POST is an array like any other, and every value stored in a PHP array must have a key (which is the form field name).
You can try retrieving the data by reading from php://input:
$post_data = file_get_contents('php://input');
But the simplest solution is to provide a fieldname in your XHR call.
You are setting the Content-Type to application/x-www-form-urlencoded, but you are setting the content to json. I'm guessing this is confusing your PHP webserver. Try setting your POST contents to what you tell the server it will be (application/x-www-form-urlencoded) or read the raw HTTP contents in php://input.
If you set the Content-Type to application/x-www-form-urlencoded then naturally PHP will want to parse the POST body. But as the data does not actually constitute form data, it is discarded as invalid.
You need to set the correct CT application/json (actually doesn't matter) so PHP will leave it alone. Then it becomes available as php://input or $HTTP_RAW_POST_DATA
