Moodle php - moodle在哪裏檢查提供的註冊密鑰是否與課程的預定義註冊密鑰相匹配？

Question

我正在創建一個moodle網站。我已經用他們特定的註冊密鑰等設置了我的課程。但是我想知道什麼.php文件以及該文件中的哪些位置（在moodle文件中），Moodle會檢查用戶輸入的註冊密鑰是否與我設置的匹配作爲課程的註冊密鑰...

感謝您的幫助！

UPDATE -------- 我按照羅素英格蘭的建議做了，但是當我進入我輸入我的註冊碼的頁面時，頁面沒有加載或頁面被重定向到我的moodle主頁。我存儲註冊密鑰的表是user_enrolment_keys。

這裏是更新的驗證功能：

public function validation($data, $files) { 
    global $DB, $CFG, $USER; 

    $errors = parent::validation($data, $files); 
    $instance = $this->instance; 

    if ($this->toomany) { 
     $errors['notice'] = get_string('error'); 
     return $errors; 
    } 
     //--------Russell's suggestion-------------- 
if ($instance->password) { 
    $params = array('user_email' => $USER->email, 'course_id' => $instance->courseid,  'enrolment_key' => $data['enrolpassword']); 
    if (!$DB->record_exists('user_enrolment_keys', $params)) { 
     $errors['enrolpassword'] = get_string('passwordinvalid', 'enrol_self'); 
     return $errors; 
    } 
} 
    //What I tried last (did not work either)... 
    /*$uemail = $USER->email; 
    $userscoursekey = 'testing'; 

    $connecty = mysqli_connect("localhost", "...", "...", "..."); 
    mysql_select_db('user_enrolment_keys', $connecty); 

      $var2 = $instance->courseid; 
    $resulty = mysqli_query($connecty, "SELECT * FROM user_enrolment_keys WHERE user_email='$uemail' AND course_id='$var2'"); 
    $numrows = $resulty->num_rows; 

    if($numrows > 0) 
    { 
     while($row = mysqli_fetch_assoc($resulty)) 
     { 
      $userscoursekey = $row['enrolment_key']; 
     } 
    } 


    $instance->password = $userscoursekey; 

    my_sqli_close($connecty); //Close the database connection.*/ 

    if ($instance->password) { 
     if ($data['enrolpassword'] !== $instance->password) { 
      if ($instance->customint1) { 
       $groups = $DB->get_records('groups', array('courseid'=>$instance->courseid), 'id ASC', 'id, enrolmentkey'); 
       $found = false; 
       foreach ($groups as $group) { 
        if (empty($group->enrolmentkey)) { 
         continue; 
        } 
        if ($group->enrolmentkey === $data['enrolpassword']) { 
         $found = true; 
         break; 
        } 
       } 
       if (!$found) { 
        // We can not hint because there are probably multiple passwords. 
        $errors['enrolpassword'] = get_string('passwordinvalid', 'enrol_self'); 
       } 

      } else { 
       $plugin = enrol_get_plugin('self'); 
       if ($plugin->get_config('showhint')) { 
        $hint = core_text::substr($instance->password, 0, 1); 
        $errors['enrolpassword'] = get_string('passwordinvalidhint', 'enrol_self', $hint); 
       } else { 
        $errors['enrolpassword'] = get_string('passwordinvalid', 'enrol_self'); 
       } 
      } 
     } 
    } 

    return $errors; 



    // END DEFAULT BLOCK 
}

它在文件中的自定義自報名表

在功能驗證（）驗證/enrol/self/locallib.php它檢查如果沒有，則密碼匹配並顯示錯誤。

UPDATE：

我可能會做這樣的驗證功能

添加$ USER變量在頂部

global $DB, $CFG, $USER; 

然後檢查中存在的用戶，當然和密碼組合您新創建的許可證表）;

$params = array('userid' => $USER->id, 'courseid' => $instance->courseid, 'password' => $data['enrolpassword']); 
if (!$DB->record_exists('local_licence_table', $params)) { 
    $errors['enrolpassword'] = get_string('passwordinvalid', 'enrol_self'); 
    return $errors; 
}
