$http angularjs POST don't send my data?

Question

my angularjs $http

userId = '1';

$http({
url: "php/loadTab.php",
method: "POST",
data: userId
}).success(function(data, status, headers, config) {
    console.log(data);
}).error(function(data, status, headers, config) {
});

heck, POST doesn't send the data to my php. I do echo $_POST['userId'] it returned undefined index. I also tried data:'userId':'1'

$http sends data as JSON, that's why there is nothing in PHP's $_POST. There numerous similar questions here on SO. — gkalpak

Angular sends the data as JSON, not form encoded key/value pairs so you can set data to an object. You almost have it on your second try but you need to include the curly braces, which define an object:

data: { 'userId' : userId }

Now, on the PHP side you need to access the raw POST data to decode the JSON like so:

$data = json_decode(file_get_contents('php://input'));
echo $data->userId;

I seem still don't pass the data. still got the same error.

Did you try it and it worked ? Because last time I checked, $http would by default send data as JSON, so nothing would be found in PHP's $_POST variable.

@ExpertSystem so? just now I use params:{'userId','1'} and it worked but it's $_GET; I need $_POST

See my comment above.

@user3522457 see updated answer. ExpertSystem is correct about the JSON, so you need to access it in a different way on the PHP side.
