如何使用CodeIgniter和AngularJS从表单中插入值？

<?php
class InsertController extends CI_Controller {
    public function insertData() {
        $data = array(
            'name' => $this->input->post('name'),
            'email' => $this->input->post('email')
        );

        $this->db->insert('users', $data);

        if ($this->db->affected_rows() > 0) {
            $response['status'] = 'success';
            $response['message'] = 'Data inserted successfully.';
        } else {
            $response['status'] = 'error';
            $response['message'] = 'Failed to insert data.';
        }

        echo json_encode($response);
    }
}
?>

<div ng-app="myApp" ng-controller="myCtrl">
    <form ng-submit="insertData()">
        <input type="text" ng-model="name" placeholder="Name" required>
        <input type="email" ng-model="email" placeholder="Email" required>
        <button type="submit">Submit</button>
    </form>

    <div ng-show="message" ng-class="{'success': status == 'success', 'error': status == 'error'}">
        {{message}}
    </div>
</div>

<script>
var app = angular.module('myApp', []);

app.controller('myCtrl', function($scope, $http) {
    $scope.insertData = function() {
        $http.post('/insertController/insertData', {
            name: $scope.name,
            email: $scope.email
        }).then(function(response) {
            $scope.status = response.data.status;
            $scope.message = response.data.message;
        });
    };
});
</script>
