POSTING data from Angular UI bootstrap modal window to PHP - mysql

Question

I have a angular-ui modal, that is controlled with below controller:
var emailModal = angular.module('myApp.emailModal', ['ui.bootstrap', 'ui.bootstrap.tpls']);
emailModal.controller('ModalCtrl', ['$scope', '$uibModal', function ($scope, $uibModal) {
$scope.open = function () {
var modalInstance = $uibModal.open({
templateUrl: 'components/emailModal/emailModalView.html',
backdrop: true,
controller: 'modalInstanceCtrl'
});
}
}]);
emailModal.controller('modalInstanceCtrl', function ($scope, $uibModalInstance, $http) {
//create blank object to handle form data.
$scope.user = {};
//calling our submit function.
$scope.submitForm = function() {
//posting data to php file
$http({
method: 'POST',
url: 'components/emailModal/emailInsert.php',
data: $scope.user, //forms user object
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
})
.success(function(data) {
if (data.errors) {
//showing errors.
$scope.errorEmail = data.errors.email;
} else {
$scope.message = data.message;
}
});
};
});
This is the actual modal view:
<form name="userForm" ng-submit="submitForm()">
<div class="modal-header">
<h3 class="modal-title">Register</h3>
</div>
<div class="modal-body">
<div class="form-group">
<label>E-Mail Address</label>
<input type="email" name="email" class="form-control" ng-model="user.email" placeholder="Email address" />
<span ng-show="errorEmail">{{errorEmail}}</span>
</div>
</div>
<div class="modal-footer">
<button type="submit" class="btn btn-default">Submit</button>
</div>
</form>
Modal loads with no problem, bute once clicked to submit, nothing happens. I get no error once so ever in the console. What am I doing wrong? This is my PHP file, as well:
$errors = array();
$data = array();
// Getting posted data and decodeing json
$_POST = json_decode(file_get_contents('php://input'), true);
// checking for blank values.
if (empty($_POST['email']))
$errors['email'] = 'E-Mail erforderlich.';
if (!empty($errors)) {
$data['errors'] = $errors;
} else {
$data['message'] = 'The data should now be inserted into database!';
}
// response back.
echo json_encode($data);
?>
EDIT 1.
The event is triggered in Dev Tools - Network.
This is what I get:
Request URL: http://localhost:63342/url-to/emailInsert.php
Request method: POST
Remote address: 127.0.0.1:63342
Status code: 200 OK
Version HTTP/1.1
The page is not reloading on submit, at all, there is no error in Dev Tools - Console. It gives a OK status even though the email has not been ineserted into input, therefore it should print an error, which it doesn't do.
Any help is greatly appreciated.
