表单无法正常工作 PHP JS

  • 772

该站点每隔一段时间工作一次！（如果我写了一个不在数据库中的登录名，那么它不会显示任何内容，如果有这样的登录名，那么它会显示一个错误，但是如果在这个错误之后你输入了一个登录名不在数据库中，则显示“您已注册”）

我是新人，请帮忙。

PHP：

    include 'includes/db.php';
    $data = $_POST;
                        if(isset($data['do-signup']) ){

                            $errors = array();
                            if(R::count('users','login = ? OR password = ?',array($data['login'],password_hash($data['password'],PASSWORD_DEFAULT))) > 0){
                                $errors[] = '<div class="has-error it-error">Такой пользователь или пароль уже существует</div>';
                            }
                            if(empty($errors)){
                                $user = R::dispense('users');
                                $user->login = $data['login'];
                                $user->password = password_hash($data['password'],PASSWORD_DEFAULT);
                                R::store($user);
                                echo 'Вы зареганы';
                                header('Location: /');
                            }else{
                                echo 'Одни ошибки в коде';
                            }
                        }
?>

和 JS：


    var passwordRegex = /^[A-Za-z0-9_-]{6,18}$/;
    var loginRegex = /^[A-Za-z0-9_-]{4,16}$/;
    var validPassword = false;
    var validConfirm = false;
    var validName = false;
    function validationlogin(){
        var name = $('#login').val();
        if(loginRegex.test(name) && name != ''){
        validName=true;
        $('#login').removeClass('has-error').addClass('has-sucsess');
        }else{
        validName=false
        $('#login').removeClass('has-sucsess').addClass('has-error');
        }
        if(name ==''){
            validName = false;
            $('#login').removeClass('has-error').addClass('has-sucsess');
        }
    };
    setInterval(validationlogin , 300);


    function validationpassword(){
        var password = $('#password').val();

        if(passwordRegex.test(password) && password != '' ){
            validPassword=true;
            $('#password').removeClass('has-error').addClass('has-sucsess');
        }else{
            validPassword=false;
            $('#password').removeClass('has-sucsess').addClass('has-error');
        }
        if(password ==''){
            validPassword = false;
            $('#password').removeClass('has-error').addClass('has-sucsess');
        }
    };
    setInterval(validationpassword , 300);

    function validationconfirm(){
        var confirm = $('#confirm_password').val();
        var password = $('#password').val();
        if(confirm == password){
            validConfirm = true;
            $('#confirm_password').removeClass('has-error').addClass('has-sucsess');
        }else{
            $('#confirm_password').removeClass('has-sucsess').addClass('has-error');
        }
        if(confirm == ''){
            validConfirm = false;
            $('#confirm_password').removeClass('has-error').addClass('has-sucsess');
        }
    }
    setInterval(validationconfirm , 300);


    $('.signup-form').submit(function(event){
        event.preventDefault();
        if(validName == true && validPassword == true && validConfirm == true){
            $('.signup-form').unbind('submit').submit();
        }
    });
    $('.login-form').submit(function(event){
        event.preventDefault();
        if(validName == true && validPassword == true){
            $('.login-form').unbind('submit').submit();
        }
    })
});

    通过用户操作和调用取消表单提交事件.submit()，您可以防止name=value按钮进入请求数据，因此阻止

    if( isset($data['do-signup']) ) {

    执行不起作用。

    $('.signup-form').submit(function(event) {
  if (!validName || !validPassword || !validConfirm) {
    return false;
  }
});
