Registration form
This is in continuation of the tutorial on making a membership based web site. Please see the previous page for more details.
Download the code
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.
The login form
Here is the HTML code for the login form.
Logging in
We 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) <= 0) { $this->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 pages
For 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:
CheckLogin()) { $fgmembersite->RedirectToURL("login.php"); exit; } ?>
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.

Поле для ввода пароля - обычное текстовое поле, вводимый текст в котором в зависимости от браузера отображается звёздочками или точками. Такая особенность предназначена для того, чтобы никто не подглядел вводимый пароль. Хотя вводимый текст и не показывается на экране, на сервер введённая информация передаётся в открытом виде без шифрования. Поэтому использование этого поля не обеспечивает безопасности данных и их можно перехватить.
Синтаксис создания следующий.
Атрибуты совпадают с атрибутами текстового поля и перечислены в табл. 1.
Поле для пароля нашло широкое применение на сайтах для авторизации пользователей и разграничения доступа к разделам сайта, где требуется подтвердить свои полномочия. В примере 1 показано, как создавать подобные поля.
Пример 1. Поле с паролем
В результате получим следующее (рис. 1).
Рис. 1. Вид поля с паролем
К полю с паролем применимы стилевые свойства задающие параметры цвета, фона, рамки и др. В примере 2 показано добавление фоновых картинок к полям формы. За основу возьмём стиль как для текстовых полей.
Пример 2. Добавление изображения в текстовое поле
Результат данного примера показан на рис. 2. Картинки добавляются в качестве фона, поэтому текст обязательно надо сдвинуть вправо через padding-left , в противном случае он будет выводиться поверх изображения.
Всем привет. Итак, мы изучили несколько элементов для создания форм. Пришло время объединить наши знания для решения задачи побольше. Давайте создадим самую простую форму для авторизации на сайте. Для этого нам необходимы два поля, делаем и привязываем к ним подписи.
Первое поле – для логина, второе – для пароля. И вот со вторым не все так просто. Поскольку на текущий момент оно представляет собой просто поле для ввода текста.
Результат в браузере:
Чтобы введенный в нем текст заменялся на звездочки, как это принято для поля такого типа, необходимо сделать одно простое действие. А именно, осуществить замену значения атрибута type на password :
Результат:
Кнопка отправки формы
Ну, вот. Наша форма уже почти готова. Теперь, чтобы завершить ее создание, необходимо сделать кнопку, которой будет осуществляться отправка формы. Задача решается с применением тега с типом submit .
Если на кнопке должна присутствовать какая-то надпись, то ее можно сделать, используя атрибут value . Задавать имя кнопке или нет – на ваше усмотрение, то если вы это сделаете, то сервер будет получать это имя, а также значение кнопки.
Как правило, в имени кнопки отправки формы есть потребность тогда, когда у формы есть несколько кнопок, каждая из которых выполняет определенное действие. Благодаря этому сервер, получая от браузера имя и значение кнопки, понимает, на какую именно кнопку нажал пользователь и что, соответственно, необходимо выполнить.
В итоге код нашей формы получится следующим:
Результат в браузере:
Login forms can be found in websites with forums, shops, WordPress and mostly everything on the internet requires login form somewhere to get access to something. The whole web is incomplete without login forms and registration, signups forms.
HTML forms will be first which most of us come across and with proper CSS which gives style to the HTML structure . In latest HTML versions i guess HTML seems to have opted for CSS3 as their default structure styling option. Anyways what you find here is the pre designed HTML, CSS forms built by front end developers and shared to the public for free to use.
Try to use all these free login form templates as most of them also have pre built HTML validation features as well as some opt jQuery or HTML validation (like the Login/Register form with pass meter below).
