Question

我正在使用Codeigniter 3，我提到了各种类似问题的stackoverflow链接，如地雷。但我无法解决这个问题。回调函数customAlpha是从file-＆gt; MY_Form_validation.php调用的，它当前位于我项目的libraries文件夹中。我多次更改正则表达式，但没有用。请帮忙。

我终于能够自己解决这个问题了。以下是有效的解决方案。

MY_Form_validation.php

class MY_Form_validation extends CI_Form_validation 
{

    function __construct($config = array())
    {
      parent::__construct($config);
    }

    public function customAlpha($str)
    {

        if ( !preg_match('/^([a-z]+(-| )?)+$/', $str) )
        {   
            return false;

        }
        else
        {
            return true;

        } 

    } 

}

Login_c.php

    class Login_c extends CI_Controller 
{
    function __construct() 
    { 
        parent::__construct(); 
        $this->load->helper(array('form', 'url'));
        $this->load->library('encrypt');
        $this->load->model('User/login_m');
        $this->load->library('session');
        $this->load->library('form_validation');
    } 

    public function register_user()  
    {


        $this->form_validation->set_rules(
        'uname', 'Full Name',
        'required|min_length[4]',
        array(
                'required'      => 'Please provide %s.'
        )
        );

        $this->form_validation->set_rules('upass', 'Password', 'required|min_length[5]');
        $this->form_validation->set_rules('cpass', 'Password Confirmation', 'required|matches[upass]');
        $this->form_validation->set_rules('uemail', 'Email', 'required|valid_email|is_unique[user.uemail]');

        $this->form_validation->set_rules('umobile', 'Mobile Number', 'required|min_length[10]|max_length[10]');

        $validation = $this->form_validation->customAlpha($this->input->post('uname'));

        if($this->input->post('oemail'))
        {
            $this->form_validation->set_rules('oemail', 'Email', 'required|valid_email|is_unique[user.oemail]');
            $oemail = $this->input->post('oemail');
        }
        else if ($this->form_validation->run()== FALSE) 
        {
            $errors['err'] = validation_errors();
            $this->load->view('User/signup.html',$errors);

        } 
        else if($validation == false)
        {   
            $errors['err'] = "Error in name field";
            $this->load->view('User/signup.html',$errors);
        }
        else 
        {
