无法访问与您的字段名称相对应的错误消息 [英] Unable to access an error message corresponding to your field name

问题描述

我有一个回调函数check_captcha可以看到 $ row 是 == 0 还是 == 1 （此信息从sql查询）。

I have a callback function that check_captcha which sees if $row is ==0 or == 1 (this information is queried from sql).

问题是我不能从 $ self-> gt_ form_validation-> set_rule（'captcha'，'call_back_check_captcha'） ，因为我的函数接受 $ row var。我现在调用它的方式，我得到一个无法访问的错误消息。如何使这项工作？

The problem is that I can not call it from $self->form_validation->set_rule('captcha', 'call_back_check_captcha') due to the fact that my function takes in a $row var. The way I'm calling it now I get a Unable to access error message. How can I make this work?

function check_captcha( $row)
{
    if($row ==0)//didnt find any
    {
        $this->form_validation->set_message('captcha', 'text dont match captcha');
        return FALSE;
    }
    else
    {
        return TRUE;
    }
}


function create_member() 
        {   

            $past = time() - 7200; 

        $this->db->query("DELETE FROM captcha WHERE captcha_time <".$past);                 
        $sql = "SELECT COUNT(*) AS count FROM captcha WHERE word =? AND ip_address =?";     
        $binds = array($_POST['captcha'], $this->input->ip_address(), $past);
        $query= $this->db->query($sql, $binds);

        $row = $query->row(); //row query rows : if it found an entry =1 

            $self->check_captcha($row->count);

        //VALIDATIONS
        $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_address', 'Email Address', 'trim|required|valid_email|unique[user.email_address]');
        $this->form_validation->set_rules('username', 'Username', 'trim|required|min_length[4]|unique[user.username]');
        $this->form_validation->set_rules('password', 'Password', 'trim|required|min_length[4]|max_leng[32]');
        $this->form_validation->set_rules('password2', 'Password Confirmation','trim|required|matches[password]');
        if(!$_POST['captcha']){
        $this->form_validation->set_rules('captcha', 'Captcha','trim|required');}else{
        $this->form_validation->set_rules('captcha', 'Captcha', 'callback_check_captcha');}

        if($this->form_validation->run()==FALSE)
        {   //this -> to the curr obj(UserController) && registraion() points to the the function in controller
            $this->registration();  //reloads reg page so they can fill out right stuff
        }
        else

推荐答案

$this->form_validation->set_message('check_captcha', 'text dont match captcha');

邮件名称对应于函数，而不是字段。因此将其设置为 check_captcha 将修复您的错误。错误讯息将使用正确的栏位名称。

The message name corresponds to the function, not the field. So setting it to "check_captcha" will fix your bug. The error message will use the correct field name.
