我試圖驗證我的用戶服務器端與PHP和它說我得到一個致命錯誤：調用未定義的函數reGenPassHash（）在/ home/xtremer/public_html/kowmanager/application/models /第13行的loggedin.php現在我有包含reGenPassHash函數自動加載的模型，所以我認爲它可以使用，但由於某種原因它不是因爲這個消息。有人解釋爲什麼？驗證與php
型號：
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;
}
}

編輯：
我想確保我的邏輯是正確的。我應該在我的控制器中使用regenPassHash函數調用嗎？
編輯2：
這是我的密碼功能如何看待（getfunc模型）的例子：
<?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' => $user_id
));
redirect('cpanel/index');
}
}
}
型號：
public function check_login($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;

return false;

你能告訴我們reGenPassHash（）函數的模型代碼嗎？你確定在check_login函數中包含該文件嗎？ – 2011-12-31 18:02:52
如果它的自動加載不意味着它包含在這個模型之上。 – 2011-12-31 18:04:05
