Постановка задачи

Разработать функциональный интернет-магазин по продаже техники.

Теоретическая часть

Для разработки данного интернет-магазина были использованы:

- Язык разметки HTML;

- Каскадные таблицы стилей CSS;

- Языки программирования PHP.

Выполнение работы

Создание базы данных

Для обеспечения функциональных возможностей сайта была создана база данных «Basa» (Рис.1). База данных создавалась при помощи СУБД PhpMyAdmin.

Рис.1

Затем, для регистрации и учёта пользователей, в БД была создана таблица «register» (Рис.2).

Рис.2

Создание форм для регистрации и входа

Для реализации взаимодействия сайта и базы данных было создано 2 файла:

- reg.php

<?php

$db = mysql_connect ("127.0.0.1","root");

mysql_select_db ("Basa",$db);

          if (isset($_POST['Login'])) { $login = $_POST['Login']; if ($login == '') { unset($login);} }

if (isset($_POST['Pass'])) { $pass=$_POST['Pass']; if ($pass =='') { unset($pass);} }

          if (isset($_POST['Email'])) { $email=$_POST['Email']; if ($email =='') { unset($email);} }

          $login = $_POST['Login'];

          $pass = $_POST['Pass'];

          $email = $_POST['Email'];

          if (empty($login) or empty($pass) or empty($email))

{

          setcookie("RegisterError", "Вы оставили пустые поля.",time()+1);

          header( 'Location: /HTML/Glav.php', true, 303 );

          exit ();

}

$login = stripslashes($login);

  $login = htmlspecialchars($login);

          $pass = stripslashes($pass);

$pass = htmlspecialchars($pass);

          $email = stripslashes($email);

$email = htmlspecialchars($email);

$login = trim($login);

$pass = trim($pass);

          $email = trim($email);

          $result = mysql_query("SELECT ID FROM register WHERE Login='$login'",$db);

          $myrow = mysql_fetch_array($result);

if (!empty($myrow['ID'])) {

          setcookie("RegisterError", "Пользователь с таким логином уже существует.",time()+1);

          header( 'Location: /HTML/6strun.php', true, 303 );

exit ();

}

$result2 = mysql_query ("INSERT INTO register (Login,Pass,Email) VALUES('$login','$pass','$email')");

if ($result2=='TRUE')

{

          setcookie("RegisterError", "Регистрация прошла успешно.",time()+1);

          header( 'Location: /HTML/6strun.php', true, 303 );

}

          else {

          setcookie("RegisterError", "Произошла ошибка при регистрации.",time()+1);

          header( 'Location: /HTML/6strun.php', true, 303 );

}        

?>

- sig.php

<?php

           if (isset($_POST['exit']))

           {

           setcookie("login", "");

           header( 'Location: /HTML/6strun.php', true, 303 );              

           exit();

           }

           else

           {

$db = mysql_connect ("127.0.0.1","root");

mysql_select_db ("Basa",$db);

           if (isset($_POST['Logine'])) { $login = $_POST['Logine']; if ($login == '') { unset($login);} }

if (isset($_POST['Passe'])) { $pass=$_POST['Passe']; if ($pass =='') { unset($pass);} }

           $login = $_POST['Logine'];

           $pass = $_POST['Passe'];

           setcookie("login", "");

           if (empty($login) or empty($pass))

{

           setcookie("SignError", "Вы оставили незаполненные поля.",time()+1);

           header( 'Location: /HTML/Glav.php', true, 303 );

           exit ();

}

$login = stripslashes($login);

$login = htmlspecialchars($login);

           $pass = stripslashes($pass);

$pass = htmlspecialchars($pass);

$login = trim($login);

$pass = trim($pass);

$result = mysql_query("SELECT ID FROM register WHERE login='$login'",$db);

           $myrow = mysql_fetch_array($result);

if (empty($myrow['ID'])) {

           setcookie("SignError", "Неверный логин!",time()+1);

           header( 'Location: /HTML/6strun.php', true, 303 );

exit ();

}

$result2 = mysql_query ("SELECT * FROM register WHERE login='$login'");

           $myrow = mysql_fetch_array($result2);

if (!empty($result2))

{

           if ($myrow['Pass'] == $pass) {

           header( 'Location: /HTML/Glav.php', true, 303 );

           setcookie("login", $login);

           }

           else

           {

           setcookie("SignError", "Неверный пароль!",time()+1);

           header( 'Location: /HTML/6strun.php', true, 303 );              

           }

}

           else {

           setcookie("SignError", "Неверный логин или пароль!",time()+1);

           header( 'Location: /HTML/6strun.php', true, 303 );              

}

           }

?>

Затем была создана форма для регистрации и входа пользователя.

<?php

if(!empty($_COOKIE["RegisterError"]))

{

echo "<script type=\"text/javascript\">alert('".$_COOKIE["RegisterError"]."');</script>";

}

if(!empty($_COOKIE["SignError"]))

{

echo "<script type=\"text/javascript\">alert('".$_COOKIE["SignError"]."');</script>";

}

?>

           <body>

                          <title>Muz Torg</title>
