我如何验证我没有从表单中得到的东西。我想验证我的变量，我希望这个规则是 is_uniqe() 来检查重复项。

我尝试将 $rules 数组中的规则设置为 array('field' => $this->characterNAME, 'rules' => 'is_unique[members.char_name]) 但没有效果我尝试在其上调用 is_unique()拥有但没有效果，我尝试将变量分配给 $_POST['charNAME'] = $this->characterNAME; 然后将其传递给 set_rules() 但没有效果。

如何验证我的变量？

我的代码：

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Registration extends CI_Controller {

var $characterNAME = "";
var $characterCORP = "";
var $characterALLY = "";
var $characterJDAT = "";

function __construct() {
    parent::__construct();
    $this->load->helper('form');
    $this->load->library('form_validation');
    $this->load->model('Registration_model', 'reg');
}

public function index()
{

    $this->load->view('registration_view');
}

function insert()
{

    $rules = array(
        array(
            'field' => 'username',
            'label' => 'Username',
            'rules' => 'required|min_length[6]|max_length[250]|is_unique[members.username]'
            ),
        array(
            'field' => 'password',
            'label' => 'Password',
            'rules' => 'required|min_length[6]|max_length[250]|md5'
            ),
        array(
            'field' => 'apiid',
            'label' => 'apiid',
            'rules' => 'required|integer|min_length[6]|max_length[250]|callback_api_check[' . $this->input->post('apikey') . ']'
            ),
        array(
            'field' => 'apikey',
            'label' => 'apikey',
            'rules' => 'required|min_length[6]|max_length[255]'
            ),
        );

    $_POST['charNAME'] = $this->characterNAME;
    $this->form_validation->set_rules('charNAME', 'CharacterName', 'is_unique[members.char_name]');
    $this->form_validation->set_rules($rules);

    if($this->form_validation->run() == FALSE) 
    {
        $this->load->view('registration_view'); 
    } else {

        // PROCESS REGISTRATION 
        $this->reg->add_user($_POST['username'], $_POST['password'], $_POST['apiid'], $_POST['apikey'], $this->characterNAME, $this->characterCORP, $this->characterALLY, $this->characterJDAT);
        // REDIRECT
        $this->load->view('registration_done');
    }
}

function api_check($apiid, $apikey) 
{
    $url = 'http://api.eveonline.com/account/Characters.xml.aspx?keyID='.$apiid.'&vCode='.$apikey;

    $xml = new DOMDocument();
    $xml->load($url);

    $chars = $xml->getElementsByTagName('row');

    foreach ($chars as $character) 
    {
        $charid = $character->attributes;
        $curl = 'http://api.eveonline.com/eve/CharacterInfo.xml.aspx?keyID='. $apiid . '&vCode='.$apikey . '&characterID=' . $charid->item(1)->nodeValue;

        $cxml = new DOMDocument();
        $cxml->load($curl);

        $corp = $cxml->getElementsByTagName("corporation");
        $ally = $cxml->getElementsByTagName("alliance");
        $char = $cxml->getElementsByTagName("characterName");
        $jdat = $cxml->getElementsByTagName("corporationDate");

        // Check database instead

        if($this->reg->validate_entity($corp->item(0)->nodeValue) || $this->reg->validate_entity($ally->item(0)->nodeValue)) 
        {
            $this->characterNAME = $char->item(0)->nodeValue;
            $this->characterCORP = $corp->item(0)->nodeValue;
            $this->characterALLY = $ally->item(0)->nodeValue;
            $this->characterJDAT = $jdat->item(0)->nodeValue;
            return true;
        }

    }
    $this->form_validation->set_message('api_check','None of the characters on this account are allowed to join.');
    return false;
}

您可以通过（示例）直接调用 is_unique 函数来验证您的表单输入不是重复的：

$this->form_validation->is_unique($email, 'users.email');

这将返回一个布尔值 true/false。True = 是唯一的——在这种情况下

因此，您可以将其放在 if() 中并以这种方式检查...

希望这可以帮助
