Question

我已经看了这个问题的答案已经3个小时了但是我不能删除这个恼人的通知......任何人都可以帮助我...它保持pop-ping'注意：未定义的索引：代码。

继承人代码：

 <?php
    function randomcode() {
        $var = "abcdefghijkmnopqrstuvwxyz0123456789";
        srand((double)microtime()*1000000);
        $i = 0;
        $code = '' ;
        while ($i <= 7) {
            $num = rand() % 33;
            $tmp = substr($var, $num, 1);
            $code = $code . $tmp;
            $i++;
        }
        return $code;
    }
    ?>
    <!--scripts ends here-->

    <?php 

    if(isset($_POST['save']))
    {
       $fname = $_POST['fname'];
       $lname = $_POST['lname'];
       $position = $_POST['position'];
       $username = $_POST['username'];
       $password = $_POST['password'];
       $email = $_POST['email'];
       $gender = $_POST['gender'];
       $repcode = $_POST['code'];
       $contact = $_POST['contact'];
       $age = $_POST['age'];
       $dateregistered = date("Y-m-d H:i:s");
       if (!$_POST['fname'] || !$_POST['lname'] || !$_POST['position'] || !$_POST['username'] || !$_POST['password'] || !$_POST['email'] || !$_POST['gender'] || !$_POST['code'] || !$_POST['conctact'] || !$_POST['age'] || !$_POST['code'] ){
           ?>
             <script>
                 $(document).ready(function() {
                    // show a dialog box when clicking on a link

                          $.Zebra_Dialog('<strong>Try Again! </strong>' +
                             'You did not complete all of the required fields!', {

                        });

                 });
              </script>
       <?php
       }
       else
       {
          $query="INSERT INTO users (position, fname, lname, username,password,dateregistered,repcode,email,age,gender,contact)   VALUES ('$position','$fname','$lname','$username','$password',CURRENT_TIMESTAMP,'$repcode','$email','$age','$gender','$contact') ";
          mysql_query($query);
          if($query){
                 // append here your jquery code
            ?>
              <script>
                 $(document).ready(function() {
                    // show a dialog box when clicking on a link
    $.Zebra_Dialog('<strong>Congratulations! </strong> <br> ' +
        'You have successfully registered!', {
        'type':     'confirmation',
        'title':    'Non-uniformed Personnel (NUP)'
    });
                 });
              </script>
             <?php
          }
       }
    }
    //corrected indentation
    ?>

我已经厌倦了许多教程已经删除了这种错误但没有工作...我需要你的帮助人员：（

disabled元素不会发布到服务器。

在这里，您禁用了名为code的输入元素，因此$_POST['code']将导致未定义的索引通知。

<input type="text" name="code" disabled value="<?php echo randomcode() ?>" STYLE="color: #FF3; font-family: Verdana; font-weight: bold; font-size: 12px; background-color: #72A4D2;" >
