用php验证

我正在尝试使用php验证我的用户服务器端，并且它说我遇到致命错误：在/home/xtremer/public_html/kowmanager/application/models/loggedin.php中调用未定义的函数reGenPassHash（）在第13行现在我有一个包含reGenPassHash函数的模型自动加载所以我认为它可以使用但由于某种原因它不是因为这个消息。有人解释原因吗？

型号：

public function check_login($username, $password)
{
    $generated_password = reGenPassHash($password);
    $query = "SELECT user_id WHERE username = ? AND password = ?";
    $result = $this->db->query($query, array($username, $generated_password));

    if ($result->num_rows == 1)
    {
        return $result->row(0)->user_id;

    }
    else
    {
        return false;
    }

}

控制器：

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

class Usermanagement extends CI_Controller { 

public function __construct()
{
    parent::__construct();
}   

public function index()
{
    //Config Defaults Start
    $msgBoxMsgs = array();//msgType = dl, info, warn, note, msg
    $cssPageAddons = '';//If you have extra CSS for this view append it here
    $jsPageAddons = '';//If you have extra JS for this view append it here
    $metaAddons = '';//Sometimes there is a need for additional Meta Data such in the case of Facebook addon's
    $siteTitle = '';//alter only if you need something other than the default for this view.
    //Config Defaults Start


    //examples of how to use the message box system (css not included).
    //$msgBoxMsgs[] = array('msgType' => 'dl', 'theMsg' => 'This is a Blank Message Box...');

    /**********************************************************Your Coding Logic Here, Start*/

    if(!$this->session->userdata('logged_in'))
    {
        $bodyContent = "login";//which view file
    }
    else
    {
        $bodyContent = "cpanel/index";//which view file
    }

    $bodyType = "full";//type of template

    /***********************************************************Your Coding Logic Here, End*/

    //Double checks if any default variables have been changed, Start.
    //If msgBoxMsgs array has anything in it, if so displays it in view, else does nothing.      
    if(count($msgBoxMsgs) !== 0)
    {
        $msgBoxes = $this->msgboxes->buildMsgBoxesOutput(array('display' => 'show', 'msgs' =>$msgBoxMsgs));
    }
    else
    {
        $msgBoxes = array('display' => 'none');
    }

    if($siteTitle == '')
    {
        $siteTitle = $this->metatags->SiteTitle(); //reads 
    }

    //Double checks if any default variables have been changed, End.

    $this->data['msgBoxes'] = $msgBoxes;
    $this->data['cssPageAddons'] = $cssPageAddons;//if there is any additional CSS to add from above Variable this will send it to the view.
    $this->data['jsPageAddons'] = $jsPageAddons;//if there is any addictional JS to add from the above variable this will send it to the view.
    $this->data['metaAddons'] = $metaAddons;//if there is any addictional meta data to add from the above variable this will send it to the view.
    $this->data['pageMetaTags'] = $this->metatags->MetaTags();//defaults can be changed via models/metatags.php
    $this->data['siteTitle'] = $siteTitle;//defaults can be changed via models/metatags.php
    $this->data['bodyType'] = $bodyType;
    $this->data['bodyContent'] = $bodyContent;
    $this->load->view('usermanagement/index', $this->data);
}

function login()
{
    $this->form_validation->set_rules('username', 'Username', 'trim|required|max_length[50]|xss_clean');
    $this->form_validation->set_rules('password', 'Password', 'trim|required|max_length[12]|xss_clean');

    if ($this->form_validation->run() == FALSE)
    {
        $this->index();
    }
    else
    {
        $username = $this->input->post('username');
        $password = $this->input->post('password');

        $user_id = $this->loggedin->check_login($username, $password);

        if(! $user_id)
        {
           redirect('/'); 
        }
        else
        {
            $this->session->set_userdata(array(
                'logged_in' => TRUE,
                'user_id' => $user_id
            ));
            redirect('cpanel/index');
        }
    }
}

function logout()
{
   $this->session->sess_destroy();
   $this->index();
}       

}

编辑：

我正在努力确保我的逻辑是正确的。我应该在控制器中使用regenPassHash函数调用吗？

编辑2：

这是我的密码函数外观（getfunc模型）的示例：

<?php
function GenPassHash($logPass)
{
    $usersalt = substr(md5(uniqid(rand(), true)), 0, 11);
    $encPass = sha1($logPass);
    $sltPass = $encPass . $usersalt;$encSPass = sha1($sltPass);
    $passArray = array($encSPass,$usersalt);
    return $passArray;
}
function reGenPassHash($postDpass, $storeSalt)
{
    $logPass = $postDpass;
    $encPass = sha1($logPass);
    $sltPass = $encPass . $storeSalt;
    $encSPass = sha1($sltPass);
    return $encSPass;
}

//useage
$logPass = "catcher05";//this could be your posted variable from registration

$passforDB = GenPassHash($logPass);
echo "<pre>";
print_r($passforDB);
echo "</pre>";
echo "Encrypted Password: " . $passforDB[0] . "<br />";
echo "Salted Value: " . $passforDB[1] . "<br />";

echo "----------------------------------<br />";
//in this example I post $passforDB[1] with the below function to stimulate having pulled it from a DB
echo reGenPassHash($logPass, $passforDB[1]); //you would query based on your username being posted and only pull the salt and encrypted pass you would use the salt in this function

?>

控制器：

function login()
{
    $this->form_validation->set_rules('username', 'Username', 'trim|required|max_length[50]|xss_clean');
    $this->form_validation->set_rules('password', 'Password', 'trim|required|max_length[12]|xss_clean');

    if ($this->form_validation->run() == FALSE)
    {
        $this->index();
    }
    else
    {
        $username = $this->input->post('username');
        $password = $this->input->post('password');
        $generated_password = $this->getfunc->reGenPassHash($password);

        $user_id = $this->loggedin->check_login($username, $password);

        if(! $user_id)
        {
           redirect('/'); 
        }
        else
        {
            $this->session->set_userdata(array(
                'logged_in' => TRUE,
                'user_id' => $user_id
            ));
            redirect('cpanel/index');
        }
    }
}

型号：

public function check_login($username, $password)
{
$query = "SELECT * WHERE username = ".$username."";
$result = $this->db->query($query);

if ($result->num_rows == 1)
{
    $passwordDB = $result->row(0)->password;
    $passwordDB2 = $result->row(0)->password2;


    return $result->row(0)->user_id;

}
else
{
    return false;
}

}

4 个答案:

答案 0 :(得分：3)

check_login（）方法看不到reGenPassHash（）函数。用对象调用reGenPassHas。

ex：$object->reGenPassHas()。

这是范围问题

答案 1 :(得分：1)

自动加载只会引发对象方法。你在调用regen函数时没有使用对象表示法，因此它被视为常规函数调用 - 并且没有定义此函数。

答案 2 :(得分：1)

您需要通过模型对象调用reGenPassHash函数，如：

$this->your_model_with_pass_function->reGenPassHash()

答案 3 :(得分：1)

我在您的代码中看到的唯一错误是您以错误的方式调用您的方法。对于任何类方法，您都需要一个对象来访问这些方法。

这可能是$ this。在您的情况下或在其他情况下的其他情况。

尝试使用$this -> reGenPassHash()调用方法仅当它依赖于模型时，否则您将需要相应的对象修饰符。

<强>更新

  1. 包括你的GenPassHash（）＆amp;控制器上的reGenPassHash（）。
  2. 而不是$this->getfunc->reGenPassHash()使用$this->reGenPassHash()
