Question

我写了一些注册页面。我想创建成功页面，注册成功信息。这是我的控制器

function register(){
    $data['success']=0;
    $data['error']=0;
    if($_POST){

        $config=array(
            array(
                'field'=>'username',
                'label'=>'Login',
                'rules'=>'trim|required|min_length[3]|max_length[64]|is_unique[users.username]'
            ),
            array(
                'field'=>'email',
                'label'=>'Adres email',
                'rules'=>'trim|required|is_unique[users.email]|valid_email'
            ),
            array(
                'field'=>'password',
                'label'=>'Hasło',
                'rules'=>'trim|required|min_length[3]|max_length[16]'
            ),
            array(
                'field'=>'password2',
                'label'=>'Potwierdź hasło',
                'rules'=>'trim|required|matches[password]'
            ),
            array(
                'field'=>'namePTS',
                'label'=>'Imie i nazwisko',
                'rules'=>'trim|required|max_length[64]'
            ),
            array(
                'field'=>'idPTS',
                'label'=>'ID postaci',
                'rules'=>'trim|required|integer|max_length[10]'
            )
        );
        $this->load->library('form_validation');
        $this->form_validation->set_rules($config);
        if ($this->form_validation->run() == FALSE){
            $data['error']=1;
            $data['errors']=validation_errors();
        } else {
            $data=array(
                'username'=>$_POST['username'],
                'email'=>$_POST['email'],
                'password'=>sha1($_POST['password']),
                'namePTS'=>$_POST['namePTS'],
                'idPTS'=>$_POST['idPTS']
            );

            $this->load->model('user');
            $userid=$this->user->create_user($data);
            if(!$userid){
                $data['success']=1;
                redirect(base_url().'users/success');
            }
        }
    }
    $this->load->view('startHeader');
    $this->load->view('register',$data);
    $this->load->view('startFooter');
}

function success(){
    $this->load->view('startHeader');
    $this->load->view('success',$data);
    $this->load->view('startFooter');
}

这是我的观点样本

<div class="login-form">
    <?php if($success==1){?>
        <!-- BEGIN ERROR BOX -->
        <div class="alert alert-danger">
            <button type="button" class="close" data-dismiss="alert">×</button>
            <p><b>Success!</b></p>
            Registration compleate!.
        </div>
        <!-- END ERROR BOX -->
    <? } ?>
</div>

正如您可以看到$ this-＆gt; user-＆gt; create_user（$ data）;没有返回错误

$data['success']=1;
redirect(base_url().'users/success');

并且在视图中我有判断成功== 1显示成功框。但我的工作不正确。我在用户/成功页面中有这样的错误

Severity: Notice

Message: Undefined variable: data

Filename: controllers/users.php

Line Number: 99

和

Severity: Notice

Message: Undefined variable: success

Filename: views/success.php

Line Number: 16

我怎么能做到这一点？

Answer 1

如果成功则查看成功页面，不要为此创建方法。

 redirect(base_url().'users/success');

=＆GT;

$this->load->view('startHeader');
$this->load->view('success',$data);
$this->load->view('startFooter');

PS：使用$this->input->post('sth')代替$_POST['sth'] 和 Codeigniter建议使用password_hash()或许使用bcrypt代替md5，sha，...

$data['success']=0;在array中设置索引，但该数组尚未定义;这就是你收到这些通知的原因。首先创建它（使用$data = array();;或者将其组合并改为编写：

$data = array('success' => 0, 'error' => 0);
