在 CodeIgniter 中确认密码

Question

I'm building a blog with CodeIgniter 3.1.3 and I have a feature in the admin to add new users. When I try to add a new user I get the following error:

The Password field does not match the confirm_password field.

although the given password in password and confrom password field is the same.

I can't figure out what causes the problem.

Here is my model:

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

Here is my controller

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');
        }

Here is my view:

<div class="row">
                        <div class="col-lg-12">
                            <div class="form-group">

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]');

Change your form validation to this and remember to autoload form validation in config/autoload.php file like $autoload['libraries'] = array('form_validation'); . If it doen't work please comment below.

Answer 2

config/autoload.php:

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

View:

<?php echo form_label('Password:'); ?>
<?php echo form_input(array('placeholder'=>'Enter your password', 'type'=>'password', 'name'=>'password')); ?>

<?php echo form_label('Confirm password:'); ?>
<?php echo form_input(array('placeholder'=>'Confirm your password', 'type'=>'password', 'name'=>'confirm_password')); ?>

Controller:

$this->form_validation->set_rules('password', 'Password', 'required');
$this->form_validation->set_rules('confirm_password', 'Confirm password', 'required|matches[password]');

Answer 3

Here is the clean and simple way to achieve that.

Here is my controller code:

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');    
    }     
}

Now for Form validation:

1. Create a form_validation.php file in config folder.

2. Then inside autoload.php file write this line.

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

Here is my code of form_validation.php file.

<?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]'
                                    ]
                            ]
];

?>

Answer 4

You must use set rules two times for the double password Confirmation

$this->form_validation->set_rules('username','Username','trim|required|min_length[3]|xss_clean');
$this->form_validation->set_rules('password', 'Password', 'required|matches[confirm_password]');

Answer 5

Create the form validation file in

application/config/form_validation.php

write the below code

<?php $config =   [
'add_user'  =>  [

   [
        'field'     =>  'first_name',
        'label'     =>  'First Name',
        'rules'     =>  'trim|required'
    ],
    [
        'field'     =>  'last_name',
        'label'     =>  'Last Name',
        'rules'     =>  'trim|required'
    ],
    [
        'field'     =>  'email',
        'label'     =>  'Email Address',
        'rules'     =>  'required|valid_email'
    ],
    [
        'field'     =>  'username',
        'label'     =>  'Username',
        'rules'     =>  'trim|required|min_length[3]'
    ],
    [
        'field'     =>  'password',
        'label'     =>  'Password',
        'rules'     =>  'required|matches[confirm_password]'
    ]
]];

Controller code

function add(){
$this->load->helper('form');

if($this->form_validation->run('add_user')){
    
    $post   =   $this->input->post();

    $_data  =   array(
        'first_name'       =>   $post['first_name'],
        'last_name'        =>   $post['last_name'],
        'username'         =>   $post['username'],
        'password'         =>   md5($post['password']);
        'group_id'         =>   $post['group'],
        'email'            =>   $post['email']  
    );

    // insert into table
    $_insert = $this->User_model->insert($_data);
    
    if($_insert){
        // if data is saved show the success message.
        $this->session->set_flashdata('user','User has been saved');
    } else {
        // if failed to save show the failed message.
        $this->session->set_flashdata('user','Failed to save the user data');
    }
    // Redirect to users page
    return redirect('admin/users');
} else {
    $data['main_content']   =   'admin/users/add';
    $this->load->view('admin/layouts/main',$data);
}}
