Angularjs Http Post to PHP and Undefined

AngularJS HTTP post to PHP and undefined

angularjs .post() defaults the Content-type header to application/json. You are overriding this to pass form-encoded data, however you are not changing your data value to pass an appropriate query string, so PHP is not populating $_POST as you expect.

My suggestion would be to just use the default angularjs setting of application/json as header, read the raw input in PHP, and then deserialize the JSON.

That can be achieved in PHP like this:

$postdata = file_get_contents("php://input");
$request = json_decode($postdata);
$email = $request->email;
$pass = $request->password;

Alternately, if you are heavily relying on $_POST functionality, you can form a query string like email=someemail@email.com&password=somepassword and send that as data. Make sure that this query string is URL encoded. If manually built (as opposed to using something like jQuery.serialize()), Javascript's encodeURIComponent() should do the trick for you.

getting undefined while sending http post method

Not entirely sure about the PHP part, but as you have json_decode in PHP, its safe to assume that PHP expects a JSON content-type

If so, here is how to post data to a url

var postUrl = 'insert.php'; // please check whether the url is correct
var dto = {
  'send_id': $scope.id,
  'send_name': $scope.name,
  'send_phone': $scope.phone,
  'send_status': $scope.status
};
$http({
  url: postUrl,
  method: 'POST',
  data: dto,
  headers: {
    "Content-Type": "application/json"
  }
})
//...

Angularjs $http post request data and response with undefined error

The problem may be in your $http call, my $http calls look like:

$http({
            method: 'post',
            url:'http://localhost/php/UpdateLastLogin.php',
            data: {...},
            config: 'Content-Type: application/json;'
        }).then(function (response) {
            console.log(response);
        }, function (response) {
            console.log(response);
        });

If I'm not wrong, you can use both, headers or config, but seems like you aren't using properly the attribute headers, the documentation says:

• headers – {function([headerName])} – Header getter function.
• config – {Object} – The configuration object that was used to generate the request.

So try to change your 'Content-Type' to 'application/json', because that's what you are sending in you http request body. If it doesn't work, change headers to config to test.

If it doesn't work either, I'd use any tool like, 'postman' to check the API, and make sure that it's working, and try to debug the PHP code (I can't help you with this part)

angular js keep showing me undefined value when i use http post

From the Docs:

$_POST

An associative array of variables passed to the current script via the HTTP POST method when using application/x-www-form-urlencoded or multipart/form-data as the HTTP Content-Type in the request.

— PHP Manual - Reserved variable - $_POST

The AngularJS framework does POST request with application/json as the HTTP Content-Type.

Instead use:¹

$data = json_decode(file_get_contents('php://input'), true);

For more information, see

• PHP Manual - Supported wrappers and protocols - php://
• PHP Manual - Function Reference - file_get_contents
• PHP Manual - Function Reference - json_decode

Angular $http post request undefined in PHP

$post = json_decode(file_get_contents('php://input'), true); 

I added this above single line in mailer.php, my problem solved. Thanks for all replies.

AngularJS HTTP Post to PHP

You need to convert your request to php known format.

I use jQuery $.param method to build it. You can write your own.

app.config(['$httpProvider', function($http) {  
    $http.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8';
    $http.defaults.transformRequest = function(data) {
            return $.param(data);
        };
    }]);

urlencoded is followed simple format:

username=Name&password=My%20Password
