Question

我正在尝试从一个函数为属性赋值，并在另一个函数中访问它。我认为这应该就这么简单。不幸的是，我似乎无法处理这个简单的任务。

这是我的控制器：

<?php
class Form_Controller extends CI_Controller {

    public $current_user;
    public $pi = 3.14;

    function index() {
        $this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email');

        $this->form_validation->set_rules('username', 'Username');
        $this->form_validation->set_rules('password', 'Password');

        if ($this->form_validation->run() == FALSE) {
            $this->load->view('login_form');
        } else {
            $this->load->model('Admin_Users_Model');
            $is_logged_in = $this->Admin_Users_Model->login();

            if ($is_logged_in) {
                $this->load->view('admin_panel/panel');
                $this->load->view('admin_panel/account_verification_status_form');
            } else {
                $this->load->view('login_form');
            }
        }
    }

    function account_verification() {

        $this->load->model('User_Id_Model');
        $data['user_data'] = $this->User_Id_Model->get_user_credentials();

        $this->current_user = $data['user_data'];

        foreach ($this->current_user as $value) {
            echo $value;
        }

        $this->load->view('admin_panel/panel');
        $this->load->view('admin_panel/account_verification_status_form');
        $this->load->view('admin_panel/account_verification_name_form', $data);
        $this->load->view('admin_panel/account_verification_status', $data);
    }

    function name_verification() {

        $selected_value = $this->input->post('verify-name');

        echo count($this->current_user) . '<br />';

        echo $this->current_user;
        echo $this->pi;
      $this->account_verification();
    }

    private function _write_to_database($user_data) {
        $this->load->model('User_Id_Model');
        $this->User_Id_Model->write_to_database($user_data);
    }

}
?>

当我致电account_verification()时，$current_user会被分配一个值，我可以打印它。之后我打电话给name_verification()，但$current_user没有价值。如果您知道这里发生了什么，请解释。

首先看看你的代码后

1）如果你从url调用name_varification而不是你没有为全局varibale分配任何值，即

    $this->current_user.

2）如果你从url调用account_varification，而不是将你的assigne数据调用到golbal变量

 $this->current_user

并且你没有在account_varification中调用name_varification，所以它再次意味着你是从url调用它的，因此它会丢失它的值，所以正确的代码要么调用first name_varificaton并将其分配给数据。

   $this->load->model('User_Id_Model');
   $data['user_data'] = $this->User_Id_Model->get_user_credentials();
   $this->current_user = $data['user_data'];

之后调用$ this-＆gt; account_verification就像你正在调用两个函数都会有值

我希望你理解。问候伊姆兰卡西姆

PHP Codeigniter，分配属性值并访问它
