auth.php 程式修改

1. 認證程式 auth.php 中 jquery() 函式在 moodle 2.3 版中沒有，所以註解掉，直接在 signup_form.php 加入登入按鈕。

                $PAGE->requires->js_init_code("buttonsCode = '$content';");
   

2. 在 login/index_form.html 的「忘記密碼連結」上方加上 Facebook 及 Google 認證登入按鈕。

   [root@dywang login]# vim index_form.html 
       <center>
   <div class="moreproviderlink">
   <a href="<?php echo $CFG->httpswwwroot; ?>/auth/elcentra/google_request.php">
   <img src="<?php echo $CFG->httpswwwroot; ?>/auth/elcentra/img/google.png"></a>
   <a href="<?php echo $CFG->httpswwwroot; ?>/auth/elcentra/facebook_request.php">
   <img src="<?php echo $CFG->httpswwwroot; ?>/auth/elcentra/img/facebook.png"></a> <br>
   </div>
           <div class="forgetpass"><a href="forgot_password.php">
   <?php print_string("forgotten") ?></a></div>
   

   
   
3. 認證 auth.php 程式判斷登入的社群帳號的 verified 參數是否存在？也就是其 email 是否確認有效？但實際測試 facebook 已確認的 email，並沒有回傳 verified，所以改成只要有從 facebook 取得 email 就接受。
