The tag of HTML is the heart of creating user entry form in web application which takes the user input data and finally submit it to server side program for further processing. Data of all the input or hidden field is taken and submitted to the server through form tag. The "submit" button is used to initiate form data submit to the server. You can also use JavaScript code for submitting the form. For example if your form name is "loginForm" then following JavaScript code can be called for submitting the form programmatically.
HTML формы — сложные элементы интерфейса. Они включают в себя разные функциональные элементы: поля ввода и , списки , подсказки и т.д. Весь код формы заключается в элемент .
Большая часть информации веб-форм передаётся с помощью элемента . Для ввода одной строки текста применяется элемент , для нескольких строк - элемент . Элемент создает выпадающий список.
Элемент создаёт надписи к полям формы. Существует два способа группировки надписи и поля. Если поле находится внутри элемента , то атрибут for указывать не нужно.
Last Name Last Name Last Name
Поля формы можно разделять на логические блоки с помощью элемента . Каждому разделу можно присвоить название с помощью элемента .

Рис. 1. Группировка полей формы
Чтобы сделать форму более понятной для пользователей, в поля формы добавляют текст, содержащий пример вводимых данных. Такой текст называется подстановочным и создаётся с помощью атрибута placeholder .
Обязательные для заполнения поля также необходимо выделять. До появления HTML5 использовался символ звездочки * , установленный возле названия поля. В новой спецификации появился специальный атрибут required , который позволяет отметить обязательное поле на уровне разметки. Этот атрибут дает указание браузеру (при условии, что тот поддерживает HTML5), указание не отправлять данные после нажатия пользователем кнопки отправить, пока указанные поля не заполнены.
Для изменения внешний вид текстового поля при получении фокуса, используется псевдокласс focus . Например, можно сделать фон текущего поля более темным или добавить цветную рамку, чтобы оно выделялось среди остальных:
Input:focus { background: #eaeaea; }
Ещё один полезный html5-атрибут — атрибут autofocus . Он позволяет автоматически установить фокус на нужном начальном поле для элементов и (только в один элемент каждой формы).

WordPress versionWe did search the internet for cool login forms but it was very difficult to find good looking ones therefore we decided to have our take on them. We would like to present 20 login forms designed and developer by Colorlib team.
Login Form 1 by Colorlib
Simple, creative and vibrant login form with a gradient background. You can use this one for all sorts of intentions, like web, mobile or desktop applications. But do get creative with it if you like.

Gorgeous, clean and modern form with an option to log in with Facebook or Google. All buttons have a nice hove effect that spices up the experience.
If your page is already super neat and tidy, a login form should be no different. Here is one that will easily meet your expectations if minimalism is your cup of tea.
A form with a three-way option of logging into the account. Either it is Facebook, Twitter or email login they prefer, this is the type of a tool that you need to feature on your page. And if they do not already have an account, you can also link it with your sign up page.
Another contemporary, trendy and enticing login form with rounded everything. This one is especially applicable to mobile users due to its currently very popular rounded corners style.
If you would like to avoid the white or single-color background, this is the login form page that you should consider. Not only does it support a full image background, but it also comes with a gradient overlay and an option to log in with Facebook or Google.
A somewhat complete opposite compared to the previous one is Login Form 10. It almost could not be more minimalistic looking while still having this up-to-the-minute feel to it.
With our collection of the best HTML5 and CSS3 login forms, you save yourself time and effort (money, too). Instead of building one from scratch, here is another killer ready-to-use template for you to employ.
Image background with a blue shadow overlay, name, image and the must-have form, that’s what’s up with Login Form 12. There is also a cool hover effect on the login button and gives you a chance to link it with your registration form for all new users.
A split screen sign up form, where one half is dedicated to an image and the other half to the form. It is a free tool which you can start using this very moment. Just download the layout and go full tilt with it.
In this collection, we have a mixture of simplistic and those a tad more complex and advanced login forms. In short, there is something for everyone and Login Form 14 is more on the minimalistic side. But why even complicate with a login form, right? To each their own.
While still keeping things to the bare minimum, one cool addition to the Login Form 15 is the image banner just above the form. With this little feature, you can make the experience slightly more engaging.
This is a login form with a full-screen image on top of which is placed a form with username and password fields and a gradient button with hover effect. Simple and straightforward.
To make it appear more personal, this framed login form template is the best fit for you. It has an image side and a form side but keeps things to the very minimum while still ensuring professionalism.
If you like to differentiate yourself and keep things original, do consider using Login Form 18. While some enjoy login pages super basic, the others want to have some additional goodies rocking the layout. And if adding a picture is what you are after, this one is for you.
Vibrant, energetic and attention-grabbing, that is what this next login form based on HTML5 and CSS3 is all about. It is also fully responsive and mobile-ready, as well as compatible with all major web browsers.
Gradient background, black sign in button with hover effect, username and password fields along with custom text and “Forgot password?” section, yep, that’s all part of Login Form 20. Sounds overwhelming but in reality, far from it.
The form is hidden unless you click on “Login” option. Really great feature for modern websites that want to avoid having a separate page for the login form. You can display the form anywhere on your website with this powerful tool.

This is in continuation of the tutorial on making a membership based web site. Please see the previous page for more details.
You can download the whole source code for the registration/login system from the link below:
The ReadMe.txt file in the download contains detailed instructions.
Here is the HTML code for the login form.
Login UserName*: Password*:
Logging inWe verify the username and the password we received and then look up those in the database. Here is the code:
function Login() { if(empty($_POST["username"])) { $this->HandleError("UserName is empty!"); return false; } if(empty($_POST["password"])) { $this->HandleError("Password is empty!"); return false; } $username = trim($_POST["username"]); $password = trim($_POST["password"]); if(!$this->CheckLoginInDB($username,$password)) { return false; } session_start(); $_SESSION[$this->GetLoginSessionVar()] = $username; return true; }
In order to identify a user as authorized, we are going to check the database for his combination of username/password, and if a correct combination was entered, we set a session variable.
Here is the code to look up the username and password.
function CheckLoginInDB($username,$password) { if(!$this->DBLogin()) { $this->HandleError("Database login failed!"); return false; } $username = $this->SanitizeForSQL($username); $pwdmd5 = md5($password); $qry = "Select name, email from $this->tablename ". " where username="$username" and password="$pwdmd5" ". " and confirmcode="y""; $result = mysql_query($qry,$this->connection); if(!$result || mysql_num_rows($result) HandleError("Error logging in. ". "The username or password does not match"); return false; } return true; }
Please notice that we must compare the value for the password from the database with the MD5 encrypted value of the password entered by the user. If the query returns a result, we set an “authorized” session variable, and then redirect to the protected content. If there are no rows with the entered data, we just redirect the user to the login form again.
Access controlled pagesFor those pages that can only be accessed by registered members, we need to put a check on the top of the page.
Notice that we are setting an “authorized” session variable in the login code above. On top of pages we want to protect, we check for that session variable. If user is authorized, we show him the protected content, otherwise we direct him to the login form.
Include this sample piece of code on top of your protected pages:
See the file: access-controlled.php in the downloaded code for an example.
Here is the CheckLogin() function code.
function CheckLogin() { session_start(); $sessionvar = $this->GetLoginSessionVar(); if(empty($_SESSION[$sessionvar])) { return false; } return true; }
These are the basics of creating a membership site. Now that you have the basic knowledge, you can experiment with it and add new features, such as a “Forgot password” page to allow the user to retrieve or change his password if he forgets it.
Updates9th Jan 2012
