angular how to pass an object in an ajax post - php

Question

I have being battling almost for day now about something that sound quite simple. I'm trying to pass an object using angular post ajax. I'm using PHP with codeigniter framework and I'm not getting any values pass. there have to be something wrong with the way I'm sending the object in angular because php is not getting anything. It's going to the right place because I'm getting a respond error saying "Trying to get property of non-object, line 173" line 173 is $AccessKey = $data->AccessKey;
this is my angular code
app.controller('loginController', function($scope, $http){
//$scope.formData = {};
$scope.processForm = function(){
$http({
method : 'POST',
url : 'http://localhost:8888/employees/login',
data : '{"AccessKey":"candoa01#gmail.com","Password":"candoa21"}'
})
.success(function(data){
console.log(data);
})
};
});
this is my php. i think here maybe I'm not using the right object name to retrieve the values.
public function login()
{
$data = $this->input->post('data');
//$data = '{"AccessKey":"candoa01#gmail.com","Password":"candoa21"}';
$data = json_decode($data);
$AccessKey = $data->AccessKey;
$Password = $data->Password;
$sql = "SELECT *
FROM Employees
WHERE Employees.AccessKey = ?
AND Employees.Password = ?";
$query = $this->db->query($sql, array($AccessKey, $Password));
if($query->num_rows() > 0)
{
$query = json_encode($query->result());
return $this->output
->set_content_type('application/json')
->set_output($query);
}
else
{
return 'Invalid AccessKey Or Password';
}
}
}

Answer 1

Try this, use params instead of data & remove ' in params
$http({
url: 'http://localhost:8888/employees/login',
method: "POST",
params: {"AccessKey":"candoa01#gmail.com","Password":"candoa21"}
})

As per your sever side code you have to pass the data as show below.
$scope.processForm = function(){
$http({
method : 'POST',
url : 'http://localhost:8888/employees/login',
data : {
data: JSON.stringify({
AccessKey: "candoa01#gmail.com",
Password:"candoa21"
})
}
})
.success(function(data){
console.log(data);
})
};

You receiving data wrong way because you are not posting data json format.This should be
$AccessKey = $this->input->post('AccessKey');
$Password = $this->input->post('Password ');
Or you can use this way
$data = $this->input->post();
$AccessKey = $data['AccessKey'];
$Password = $data['Password'];
