Question

每次返回糟糕！必须输入所有输入。仔细检查表格。

它应该返回下一个错误，但我想它不能识别我的POST变量？这是为什么？

以下代码：

PHP脚本：

if(isset($_POST['action'])) {
    switch($_POST['action']) {

        case 'register':

        $email_adress = @$_POST['register_email_address'];
        $password = hash('sha512', @$_POST['register_password']);
        $confirm_password = hash('sha512', @$_POST['register_confirm_password']);
        $safe_pin = @$_POST['register_safe_pin'];

            if(isset($email_address, $password, $confirm_password, $safe_pin)) {

                if(filter_var($email_address, FILTER_VALIDATE_EMAIL)) {

                    if($password == $confirm_password) {

                        if(strlen($safe_pin) == 4 && is_numeric($safe_pin)) {

                            if(strlen($_POST['register_password']) >= 6 && strlen($_POST['register_confirm_password']) >= 6) {

                                $insert_user = $db->prepare("INSERT INTO `users`
                                (`email_address`, `password`, `safe_pin`, `time_registered`, `activated`, `balance`, `last_login, `ip_address`, `last_ip_address`)
                                VALUES (:email_address, :password, :safe_pin, :time_registered, :activated, :balance, :last_login, :ip_address, :last_ip_address)");

                                    $insert_user->execute(array(

                                        ':email_address'        => $email_address,
                                        ':password'             => $password,
                                        ':safe_pin'             => $safe_pin,
                                        ':time_registered'      => time(),
                                        ':activated'            => 0,
                                        ':balance'              => 0,
                                        ':last_login'           => 0,
                                        ':ip_address'           => $_SERVER['REMOTE_ADDR'],
                                        ':last_ip_address'      => $_SERVER['REMOTE_ADDR']

                                    ));

                            }

                            else { echo json_encode(array('result'  => '<strong>Oops!</strong> Your password must be a minimum of 6-characters.')); }
                        }
                            else { echo json_encode(array('result'  => '<strong>Oops!</strong> Your safe-pin must be a 4-character numeric code.')); }
                    }
                            else { echo json_encode(array('result'  => '<strong>Oops!</strong> Your confirmation password must match identically to your password.')); }
                }
                            else { echo json_encode(array('result'  => '<strong>Oops!</strong> Your e-mail address must be valid.  Make sure it\'s typed properly. <br />')); }
            }
                            else { echo json_encode(array('result'  => '<strong>Oops!</strong> All inputs must be entered.  Double-check the form. <br />')); }

        break;
   }
}

jQuery的/使用Javascript

<script type="text/javascript">
  $("#sign_up").on('click', function() {
    $.post('./includes/ajax.php', { action: 'register' } , function(result) {
      var result = JSON.parse(result);
        console.log(result.result);
        $("#register_result").append(result.result);
    });
  });
$("#register_form").submit(function() {
  return false;
});

$(".alert").hide();
$("#sign_up").on('click', function() { $(".alert").show(); });
</script>

HTML代码：

<div id="register_form">
              <form class="bs-example form-horizontal" id="register_form" method="POST" action="./includes/ajax.php">
                <fieldset>
                  <legend>Create a Wallet</legend>
                      <div class="alert alert-dismissable alert-danger">
              <button type="button" class="close" data-dismiss="alert">&times;</button>
             <span id="register_result"></span>
            </div>

              </form>

Answer 1

您没有将表单传递给您的注册脚本。您必须serialize表单内容并发送帖子请求

$("#sign_up").on('click', function() {
    $.post('./includes/ajax.php', $('#register_form').serialize() + '&action=register' , function(result) {
        var result = JSON.parse(result);
        console.log(result.result);
        $("#register_result").append(result.result);
    });
});

Answer 2

我现在更新了我的答案...因为你的代码中有超过1个错误。

首先想一想你要做的是购买一个IDE（软件）来突出显示错误。这可以让你的生活变得如此轻松。

尽可能频繁地显示你的代码，一遍又一遍地阅读这些代码，注释掉一些代码来测试什么是错误的......等等！

我认为这段代码现在完全没有错误和清晰。

我改变了什么：

$email_adress至$email_address
if (strlen($_POST['register_password']) >= 6 && strlen($_POST['register_confirm_password']) >= 6) {...

到

if (strlen($_POST['register_password']) > 5 && strlen($_POST['register_confirm_password']) > 5) {...
:password改为:pwd我改变了，因为这可能是一个保留字而且不是那么明显（根据需要改变它）

和

...`last_login, `ip_address`,...

to（忘记反击）

...`last_login`, `ip_address`,...

和整个代码：

if (isset($_POST['action'])) {

    switch($_POST['action']) {

    case 'register':

        $email_address      = @$_POST['register_email_address'];
        $password           = hash('sha512', @$_POST['register_password']);
        $confirm_password   = hash('sha512', @$_POST['register_confirm_password']);
        $safe_pin           = @$_POST['register_safe_pin'];

        if (isset($email_address, $password, $confirm_password, $safe_pin)) {

            if (filter_var($email_address, FILTER_VALIDATE_EMAIL)) {

                if ($password == $confirm_password) {

                    if (strlen($safe_pin) == 4 && is_numeric($safe_pin)) {

                        if (strlen($_POST['register_password']) > 5 && strlen($_POST['register_confirm_password']) > 5) {

                            $insert_user = $db->prepare("INSERT INTO `users` (`email_address`, `pwd`, `safe_pin`, `time_registered`, `activated`, `balance`, `last_login`, `ip_address`, `last_ip_address`)
                                                         VALUES (:email_address, :pwd, :safe_pin, :time_registered, :activated, :balance, :last_login, :ip_address, :last_ip_address)");

                            $insert_user->execute(array(

                                ':email_address'        => $email_address,
                                ':pwd'                  => $password,
                                ':safe_pin'             => $safe_pin,
                                ':time_registered'      => time(),
                                ':activated'            => 0,
                                ':balance'              => 0,
                                ':last_login'           => 0,
                                ':ip_address'           => $_SERVER['REMOTE_ADDR'],
                                ':last_ip_address'      => $_SERVER['REMOTE_ADDR']

                            ));

                        }

                        else { echo json_encode(array('result'  => '<strong>Oops!</strong> Your password must be a minimum of 6-characters.')); }
                    }
                    else { echo json_encode(array('result'  => '<strong>Oops!</strong> Your safe-pin must be a 4-character numeric code.')); }
                }
                else { echo json_encode(array('result'  => '<strong>Oops!</strong> Your confirmation password must match identically to your password.')); }
            }
            else { echo json_encode(array('result'  => '<strong>Oops!</strong> Your e-mail address must be valid.  Make sure it\'s typed properly. <br />')); }
        }
        else { echo json_encode(array('result'  => '<strong>Oops!</strong> All inputs must be entered.  Double-check the form. <br />')); }

        break;
    }
}

PHP / Ajax没有返回正确的错误而没有识别POST变量？
