Call to undefined function on Codeigniter
提问by softboxkid
I have the class for resetting a user password. But the code is always gives me an error:
我有重置用户密码的课程。但是代码总是给我一个错误：
Fatal error: Call to undefined function newRandomPwd() in
C:\AppServ\www\phonebook\application\controllers\reset.php
on line 32
Here is my code:
这是我的代码：
class Reset extends CI_Controller{
function index(){
$this->load->view('reset_password');
}
function newRandomPwd(){
$length = 6;
$characters = 'ABCDEF12345GHIJK6789LMN$%@#&';
$string = '';
for ($p = 0; $p < $length; $p++) {
$string .= $characters[mt_rand(0, strlen($characters))];
}
return $string;
}
function resetPwd(){
$newPwd = newRandomPwd(); //line 32, newRandomPwd()
//is undefined
$this->load->library('form_validation');
$this->load->model('user_model');
$getUser = $this->user_model->getUserLogin();
if($getUser)
{
$this->user_model->resetPassword($newPwd);
return TRUE;
} else {
if($this->form_validation->run()==FALSE)
{
$this->form_validation->set_message('','invalid username');
$this->index();
return FALSE;
}
}
}
}
How do I make the method newRandomPwdavailable so it's not undefined?
如何使该方法newRandomPwd可用以使其不是未定义的？

newRandomPwd()is not a global function but a object method, you should use $this.
newRandomPwd()不是全局函数而是对象方法，您应该使用$this.
Change $newPwd = newRandomPwd();to $newPwd = $this->newRandomPwd();
更改$newPwd = newRandomPwd();为$newPwd = $this->newRandomPwd();
