Форма регистрации html код. Форма входа и регистрации с помощью HTML5 и CSS3

Creating a membership based site seems like a daunting task at first. If you ever wanted to do this by yourself, then just gave up when you started to think how you are going to put it together using your PHP skills, then this article is for you. We are going to walk you through every aspect of creating a membership based site, with a secure members area protected by password.

The whole process consists of two big parts: user registration and user authentication. In the first part, we are going to cover creation of the registration form and storing the data in a MySQL database. In the second part, we will create the login form and use it to allow users access in the secure area.

Download the code

You can download the whole source code for the registration/login system from the link below:

Configuration & Upload
The ReadMe file contains detailed instructions.

Open the source\include\membersite_config.php file in a text editor and update the configuration. (Database login, your website’s name, your email address etc).

Upload the whole directory contents. Test the register.php by submitting the form.

The registration form

In order to create a user account, we need to gather a minimal amount of information from the user. We need his name, his email address and his desired username and password. Of course, we can ask for more information at this point, but a long form is always a turn-off. So let’s limit ourselves to just those fields.

Here is the registration form:

So, we have text fields for name, email and the password. Note that we are using the for better usability.

Form validation

At this point it is a good idea to put some form validation code in place, so we make sure that we have all the data required to create the user account. We need to check if name and email, and password are filled in and that the email is in the proper format.

Handling the form submission

Now we have to handle the form data that is submitted.

Here is the sequence (see the file fg_membersite.php in the downloaded source):

function RegisterUser() { if(!isset($_POST["submitted"])) { return false; } $formvars = array(); if(!$this->ValidateRegistrationSubmission()) { return false; } $this->CollectRegistrationSubmission($formvars); if(!$this->SaveToDatabase($formvars)) { return false; } if(!$this->SendUserConfirmationEmail($formvars)) { return false; } $this->SendAdminIntimationEmail($formvars); return true; }

First, we validate the form submission. Then we collect and ‘sanitize’ the form submission data (always do this before sending email, saving to database etc). The form submission is then saved to the database table. We send an email to the user requesting confirmation. Then we intimate the admin that a user has registered.

Saving the data in the database

Now that we gathered all the data, we need to store it into the database.
Here is how we save the form submission to the database.

function SaveToDatabase(&$formvars) { if(!$this->DBLogin()) { $this->HandleError("Database login failed!"); return false; } if(!$this->Ensuretable()) { return false; } if(!$this->IsFieldUnique($formvars,"email")) { $this->HandleError("This email is already registered"); return false; } if(!$this->IsFieldUnique($formvars,"username")) { $this->HandleError("This UserName is already used. Please try another username"); return false; } if(!$this->InsertIntoDB($formvars)) { $this->HandleError("Inserting to Database failed!"); return false; } return true; }

Note that you have configured the Database login details in the membersite_config.php file. Most of the cases, you can use “localhost” for database host.
After logging in, we make sure that the table is existing.(If not, the script will create the required table).
Then we make sure that the username and email are unique. If it is not unique, we return error back to the user.

The database table structure

This is the table structure. The CreateTable() function in the fg_membersite.php file creates the table. Here is the code:

function CreateTable() { $qry = "Create Table $this->tablename (". "id_user INT NOT NULL AUTO_INCREMENT ,". "name VARCHAR(128) NOT NULL ,". "email VARCHAR(64) NOT NULL ,". "phone_number VARCHAR(16) NOT NULL ,". "username VARCHAR(16) NOT NULL ,". "password VARCHAR(32) NOT NULL ,". "confirmcode VARCHAR(32) ,". "PRIMARY KEY (id_user)". ")"; if(!mysql_query($qry,$this->connection)) { $this->HandleDBError("Error creating the table \nquery was\n $qry"); return false; } return true; }

The id_user field will contain the unique id of the user, and is also the primary key of the table. Notice that we allow 32 characters for the password field. We do this because, as an added security measure, we will store the password in the database encrypted using MD5. Please note that because MD5 is an one-way encryption method, we won’t be able to recover the password in case the user forgets it.

Inserting the registration to the table

Here is the code that we use to insert data into the database. We will have all our data available in the $formvars array.

function InsertIntoDB(&$formvars) { $confirmcode = $this->MakeConfirmationMd5($formvars["email"]); $insert_query = "insert into ".$this->tablename."(name, email, username, password, confirmcode) values ("" . $this->SanitizeForSQL($formvars["name"]) . "", "" . $this->SanitizeForSQL($formvars["email"]) . "", "" . $this->SanitizeForSQL($formvars["username"]) . "", "" . md5($formvars["password"]) . "", "" . $confirmcode . "")"; if(!mysql_query($insert_query ,$this->connection)) { $this->HandleDBError("Error inserting data to the table\nquery:$insert_query"); return false; } return true; }

Notice that we use PHP function md5() to encrypt the password before inserting it into the database.
Also, we make the unique confirmation code from the user’s email address.

Sending emails

Now that we have the registration in our database, we will send a confirmation email to the user. The user has to click a link in the confirmation email to complete the registration process.

function SendUserConfirmationEmail(&$formvars) { $mailer = new PHPMailer(); $mailer->CharSet = "utf-8"; $mailer->AddAddress($formvars["email"],$formvars["name"]); $mailer->Subject = "Your registration with ".$this->sitename; $mailer->From = $this->GetFromAddress(); $confirmcode = urlencode($this->MakeConfirmationMd5($formvars["email"])); $confirm_url = $this->GetAbsoluteURLFolder()."/confirmreg.php?code=".$confirmcode; $mailer->Body ="Hello ".$formvars["name"]."\r\n\r\n". "Thanks for your registration with ".$this->sitename."\r\n". "Please click the link below to confirm your registration.\r\n". "$confirm_url\r\n". "\r\n". "Regards,\r\n". "Webmaster\r\n". $this->sitename; if(!$mailer->Send()) { $this->HandleError("Failed sending registration confirmation email."); return false; } return true; }

Responsive HTML5 – jQuery Sign In – Registration Form

Responsive HTML5 Sign In / Registration form , with jQuery effects and CSS3 customization.

В данной статье будет описан процесс реализации возможности регистрации и аутентификации пользователей наиболее простейшим образом.

1. Регистрация

Начнём с регистрации. Django "из коробки" предоставляет форму создания пользователя UserCreationForm , которую мы и будет использовать для регистрации. Плюс ко всему, она автоматически делает все необходимые проверки. Например, зарегистрирован ли уже пользователь с данным именем. Построенное на основе данной формы представление будет иметь следующий вид:

From django.views.generic.edit import FormView from django.contrib.auth.forms import UserCreationForm class RegisterFormView(FormView): form_class = UserCreationForm # Ссылка, на которую будет перенаправляться пользователь в случае успешной регистрации. # В данном случае указана ссылка на страницу входа для зарегистрированных пользователей. success_url = "/login/" # Шаблон, который будет использоваться при отображении представления. template_name = "register.html" def form_valid(self, form): # Создаём пользователя, если данные в форму были введены корректно. form.save() # Вызываем метод базового класса return super(RegisterFormView, self).form_valid(form)

Как видно, зарегистрировать пользователя достаточно просто. Теперь необходимо добавить ссылку на представление в urls.py :

From django.conf.urls import patterns, include, url urlpatterns = patterns("", ... url(r"^register/$", views.RegisterFormView.as_view()), ...)

И тег {{ form }} в шаблон register.html :

Таким образом, перейдя на страницу ваш.сайт/register/ можно будет увидеть форму регистрации, которая, если повезёт, даже будет работать. Однако, выглядеть она будет страшновато. Как применить к ней форматирование и стили CSS можно догадаться из статьи или почитав документацию.

2. Аутентификация

Принципы реализации аутентификации абсолютно те же самые, но реализация немного сложнее (за счёт использования некоторых дополнительных функций). Без лишних слов, смотрим на код и читаем комментарии:

# Опять же, спасибо django за готовую форму аутентификации. from django.contrib.auth.forms import AuthenticationForm # Функция для установки сессионного ключа. # По нему django будет определять, выполнил ли вход пользователь. from django.contrib.auth import login class LoginFormView(FormView): form_class = AuthenticationForm # Аналогично регистрации, только используем шаблон аутентификации. template_name = "login.html" # В случае успеха перенаправим на главную. success_url = "/" def form_valid(self, form): # Получаем объект пользователя на основе введённых в форму данных. self.user = form.get_user() # Выполняем аутентификацию пользователя. login(self.request, self.user) return super(LoginFormView, self).form_valid(form)

Осталось, аналогично регистрации, добавить ссылку в urls.py и создать шаблон login.html (кстати говоря, подойдёт и представленный выше шаблон регистрации без каких-либо изменений).

3. Выход

4. Заключение

Скопировав и склеив всё это, можно получить минимальную систему "чтобы работало" с большим потенциалом для улучшения. Например, можно реализовать страницы восстановления и изменения пароля аналогичным образом на основе форм PasswordResetForm и PasswordChangeForm из django.contrib.auth.forms .

HTML

Теперь о двух хитрых моментах. Вы наверное заметили две ссылки в начале формы. Этот ловкий прием позволит нашей формы вести себя правильно при работе с якорями (anchors).

Второй момент связан с применением шрифта с иконками. Мы будем использовать data-attribute , чтобы отобразить иконки. Устанавливая параметр data-icon=”icon_character” с соответствующим символов в HTML, мы должны назначить лишь одно правило в CSS для установления стиля всех иконок.
