Codeigniter + Angular Js: How to receive JSON data
Solution 1
thanks for the reply. solution is as follows
$obj=json_decode(file_get_contents('php://input'));
you can test it by
print_r(json_decode(file_get_contents('php://input')));
Solution 2
$_POST
will be empty in CodeIgniter because it purposely empties it for security reasons. You need to use $this->input->post();
instead.
Solution 3
Use:
$postData = $this->input->post();
It should give you an array with all the post data.
I also advise you to turn on XSS filtering.
Following is the documentation for the Codeigniter Input Class: http://ellislab.com/codeigniter/user-guide/libraries/input.html
Solution 4
the data sent with the request is a name-value pairs so you should write some thing like that:
data : {"myformdata":JSON.stringify({email:$scope.user.email, password:$scope.user.password})}
and in code igniter you can recive the data :
$this->input->post("myformdata"); //should return what
// that JSON.stringify returned
Solution 5
Although this is already answered I quite often have this quick little utility included in many of my applications that need to accept both application/x-www-form-urlencoded
and application/json
POSTs.
if (strcasecmp($_SERVER['REQUEST_METHOD'], 'post') === 0 && stripos($_SERVER['CONTENT_TYPE'], 'application/json') !== FALSE) {
// POST is actually in json format, do an internal translation
$_POST += json_decode(file_get_contents('php://input'), true);
}
After that point you can now just use the $_POST
superglobal as you normally would, all the JSON data will be decoded for you.

This is the situation:
I have a simple app made in Angular JS that comunicate with the server through an API made in codeigniter.
There is a login system in the app. When the user enter email and password, this data are sent to the server, if the email exist and the password match, it return true.
I have made many attempts but not figure out how can i do this properly.
This is the code:
The form:
<form role="form" method="post" novalidate ng-submit="submitForm()"> <div class="form-group"> <label for="exampleInputEmail1">Email address</label> <input type="email" class="form-control" name="email" ng-model="user.name" placeholder="Enter email"> </div> <div class="form-group"> <label for="exampleInputPassword1">Password</label> <input type="password" class="form-control" name="password" ng-model="user.password" placeholder="Password"> </div> <button type="submit" class="btn btn-default">Submit</button> </form>
This is the Angular js controller:
$scope.authorized = false; $scope.user = {}; $scope.submitForm = function() { console.log("posting data...."); $http({ method : 'POST', url : 'http://127.0.0.1/api/main/login', headers: {'Content-Type': 'application/json'}, data : JSON.stringify({email:$scope.user.email, password:$scope.user.password}) }).success(function(data) { console.log(data); $scope.authorized = data; if ($scope.authorized) { $location.path("memberArea"); }; }); }
In the codeigniter method have tried many things. Right now there is just this:
function login() { print json_encode($_POST); }
But i don't know if can receive the data into the $_POST because it seems to be empty.
So the question is:
How can i receive data in the codeigniter method? Is better to send as JSON and then json_decode? I have also tried json_decode($_POST, true); But was null. But if the data are not in $_POST where are? I am little confused..
Thank you for help!
EDIT:
Thanks guys for reply. That was one thing that have tried. But somehow is not working. Now for example the method is like this:
function login() { $email = $this->input->post('email'); var_dump($email); print json_encode($email); }
But what is returned is a boolean false.
