在 CodeIgniter 中确认密码

Question

我正在使用 CodeIgniter 3.1.3 构建博客，我在管理员中有一个功能可以添加新用户。当我尝试添加新用户时，出现以下错误：

密码字段与 confirm_password 字段不匹配。

尽管 password 和 confrom password 字段中给定的密码是相同的。

我不知道是什么原因导致了这个问题。

这是我的模型：

 public function insert($data){
    $this->db->insert('users', $data);
    return true;
}

这是我的控制器

public function add(){
        //Validation Rules
        $this->form_validation->set_rules('first_name','First Name','trim|required');
        $this->form_validation->set_rules('last_name','Last Name','trim|required');
        $this->form_validation->set_rules('email','Email','trim|required|valid_email');
        $this->form_validation->set_rules('username','Username','trim|required|min_length[3]');
        $this->form_validation->set_rules('password', 'Password', 'required|matches[confirm_password]');

        $data['groups'] = $this->User_model->get_groups();

        if($this->form_validation->run() == FALSE){
            //Views
            $data['main_content'] = 'admin/users/add';
            $this->load->view('admin/layouts/main', $data);
        } else {
            //Create Data Array
            $data = array(
                'first_name'    => $this->input->post('first_name'),
                'last_name'     => $this->input->post('last_name'),
                'username'      => $this->input->post('username'),
                'password'      => md5($this->input->post('password')),
                'group_id'      => $this->input->post('group'),
                'email'         => $this->input->post('email')
            );

            //Table Insert
            $this->User_model->insert($data);

            //Create Message
            $this->session->set_flashdata('user_saved', 'User has been saved');

            //Redirect to pages
            redirect('admin/users');
        }

这是我的观点：

 <div class="row">
                        <div class="col-lg-12">
                            <div class="form-group">
                                <label>First Name</label>
                                <input class="form-control" type="text" name="first_name" value="<?php echo set_value('first_name'); ?>" placeholder="Enter First Name" />
                            </div>
                            <div class="form-group">
                                <label>Last Name</label>
                                <input class="form-control" type="text" name="last_name" value="<?php echo set_value('last_name'); ?>" placeholder="Enter Last Name" />
                            </div>
                            <div class="form-group">

                            </div>
                            <div class="form-group">

                            </div>
                            <div class="form-group">
                                <label>Password</label>
                                <input class="form-control" type="password" name="password" value="<?php echo set_value('password'); ?>" placeholder="Enter Password" />
                            </div>
                            <div class="form-group">

                            </div>
                            <div class="form-group">

                            </div>

Answer 1

$this->form_validation->set_rules('first_name','First Name','trim|required');
$this->form_validation->set_rules('last_name','Last Name','trim|required');
$this->form_validation->set_rules('email','Email','trim|required|valid_email');
$this->form_validation->set_rules('username','Username','trim|required|min_length[3]');
$this->form_validation->set_rules('password', 'Password', 'required');
$this->form_validation->set_rules('confirm_password', 'Confirm Password', 'required|matches[password]');

将您的表单验证更改为此，并记住在 config/autoload.php 文件中自动加载表单验证，如 $autoload['libraries'] = array('form_validation'); 。如果它不起作用，请在下面发表评论。

Answer 2

这是实现这一目标的简洁方法。

这是我的 controller 代码：

 public function add_user(){
    $this->form_validation->set_error_delimiters('<p class="text-danger">', '</p>');
    if ($this->form_validation->run('register_user_rules') == FALSE){
        $this->load->template('user/register');
    } else {
        $post = $this->input->post();
        unset($post['pass_confirm']);
        unset($post['submit']);
        if($this->UserModel->addUser($post)){
            $this->session->set_flashdata('feedback', 'Registration Succesfull! Please Sign in to Continue');
            $this->session->set_flashdata('feedback_class', 'alert-success');
        } else {
            $this->session->set_flashdata('feedback', 'Sorry! Please try again.');
            $this->session->set_flashdata('feedback_class', 'alert-danger');
        }
        return redirect('register');
    }
}

现在进行表单验证：

1. 在 config 文件夹中创建一个 form_validation.php --- 文件。

2. 然后在 autoload.php 文件中写入这一行。

$autoload['libraries'] = array('form_validation');

这是我的 form_validation.php 文件的代码。

 <?php

$config = [
        'register_user_rules' => [
                                    [
                                        'field' => 'fullname',
                                        'label' => 'Full Name',
                                        'rules' => 'trim|required|max_length[20]'
                                    ],
                                    [
                                        'field' => 'email',
                                        'label' => 'Email Address',
                                        'rules' => 'trim|required|valid_email'

                                    ],
                                    [
                                        'field' => 'phone',
                                        'label' => 'Phone Number',
                                        'rules' => 'trim|required|numeric|max_length[10]|regex_match[/^[0-9]{10}$/]'

                                    ],
                                    [
                                        'field' => 'password',
                                        'label' => 'Password',
                                        'rules' => 'trim|required'
                                    ],
                                    [
                                        'field' => 'pass_confirm',
                                        'label' => 'Confirm Password',
                                        'rules' => 'trim|required|matches[password]'
                                    ]
                            ]
];

?>
