Codeigniter + Angular Js: How to get JSON data

Question

This is the situation:

I have a simple application made in Angular JS that communicates with the server through an API created in the codec.

The application has a login system. When the user enters an email address and password, this data is sent to the server, if there is mail and the password matches, it returns true.

I made many attempts, but did not understand how I can do this correctly.

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"); }; }); } 

We tried a lot in the codeigniter method. Now there is only the following:

 function login() { print json_encode($_POST); } 

But I do not know if it can receive data in $ _POST, because it seems empty.

So the question is:

How can I get the data in the codeigniter method? Better to send as JSON and then json_decode? I also tried json_decode ($ _ POST, true); But it was zero. But if the data is not in $ _POST, where? I'm a little confused.

Thank you for your help!

EDIT:

Thanks guys for the answer. It was one that they tried. But somehow it doesn’t work. Now, for example, the method looks like this:

 function login() { $email = $this->input->post('email'); var_dump($email); print json_encode($email); } 

But what comes back is logical false.

Answer 1

thanks for the answer. the solution is as follows

 $obj=json_decode(file_get_contents('php://input')); 

you can check it on

 print_r(json_decode(file_get_contents('php://input'))); 

Answer 2

$_POST will be empty in CodeIgniter because it intentionally releases it for security reasons. Instead, you need to use $this->input->post(); .

CodeIgniter Input Class

Answer 3

Using:

 $postData = $this->input->post(); 

It should provide you with an array with all the message data.

I also advise you to enable XSS filtering.

The following is the documentation for the Codeigniter input class: http://ellislab.com/codeigniter/user-guide/libraries/input.html

Answer 4

the data sent with the request are name-value pairs, so you should write something like this:

 data : {"myformdata":JSON.stringify({email:$scope.user.email, password:$scope.user.password})} 

and in the code igniter you can get the data:

 $this->input->post("myformdata"); //should return what // that JSON.stringify returned 

Answer 5

Despite the fact that this has already been answered, I often get this little utility included in many of my applications, which should accept both application/x-www-form-urlencoded and application/json tags.

 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 this point, you can now simply use the superclass of $_POST , as usual, all JSON data will be decoded for you.
