Answer 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')));

Answer 2

$_POST will be empty in CodeIgniter because it purposely empties it for security reasons. You need to use $this->input->post(); instead.

Answer 3

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.

Answer 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

Answer 5

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.
