EXERCISE 1: Simple Listing
Develop a web-based application (using PHP script) to list all the contents of the table Books.
The SQL dump for the database (for the database BOOKSHOP),
-- DATABASE NAME: 'bookshop'
-- version 2.11.1
-- http://www.phpmyadmin.net
--
-- Host: localhost
-- Generation Time: Jul 26, 2011 at 06:09 AM
-- Server version: 5.0.45
-- PHP Version: 5.2.4
SET SQL_MODE="NO_AUTO_VALUE_ON_ZERO";
--
-- Database: `bookshop`
--
CREATE DATABASE `bookshop` DEFAULT CHARACTER SET latin1 COLLATE latin1_general_ci;
USE `bookshop`;
-- --------------------------------------------------------
--
-- Table structure for table `books`
--
CREATE TABLE `books` (
`isbn` varchar(15) collate latin1_general_ci NOT NULL,
`title` varchar(100) collate latin1_general_ci NOT NULL,
`authorid` varchar(3) collate latin1_general_ci NOT NULL,
`publisherid` varchar(3) collate latin1_general_ci NOT NULL,
`year` int(4) NOT NULL,
`number` int(11) NOT NULL,
PRIMARY KEY (`isbn`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci;
--
-- Dumping data for table `books`
--
INSERT INTO `books` (`isbn`, `title`, `authorid`, `publisherid`, `year`, `number`) VALUES
('1047154354', 'Computer Security', 'DG', 'JW', 2000, 5),
('7223020711', 'Anti Hacker Toolkit', 'MS', 'MGH', 2003, 3),
('0201440997', 'Computer Art Security and Science', 'MB', 'AW', 2004, 4);
The PHP code;
<?php
//1. establish connection to database server
//since it is on XAMPP, so no password for root
//BAD practice
$db=mysqli_connect("localhost","root","","BOOKSHOP");
//2. check the connection
if($db==false){
echo "Database connection fail!<br>";
echo "Error: ".mysqli_connect_error($db);
}
else{//if can connect
echo "Yeay... Connected to database<br>";
//3. sql command to SELECT all data
$sql="SELECT * FROM books";
//4. send sql command to database server
$rs=mysqli_query($db, $sql);
//5. display records
if ($rs==false){
echo "SQL Error".mysqli_error($db);
}
else{//display SQL error message
//table header
echo "<table border=1>";
echo "<tr><td>ISBN</td>".
"<td>Title</td>".
"<td>Author</td>".
"<td>Publisher</td>".
"<td>Year</td>".
"<td>Quantity</td> </tr>";
while ($record=mysqli_fetch_array($rs)){
echo "<tr>";
echo "<td>".$record['isbn']."</td>";
echo "<td>".$record['title']."</td>";
echo "<td>".$record['authorid']."</td>";
echo "<td>".$record['publisherid']."</td>";
echo "<td>".$record['year']."</td>";
echo "<td>".$record['number']."</td>";
echo "</tr>";
}
echo "</table>";
}
}
?>
EXERCISE 2: Searching
Use the database Bookshop. Develop a web-based application (using PHP script) to find a book based on the book ‘title’ and ‘year’ published.
<html>
<head>
<title>Search Book by Title and Year</title>
</head>
<body>
Search by Title and Year (published)<br>
<form method="get" action="">
Book Title <input type="text" name="txttitle"><br>
Year Published
<select name="cmbyear">
<?php
for($i=1999; $i<date('Y');$i++){
echo "<option value='$i'> $i " .
"</option>\n";
}
?>
</select><br>
<input type="submit" value="Search Book">
</form>
<hr>
<?php
//1. establish connection to database server
//since it is on XAMPP, so no password for root
//BAD practice
$db=mysqli_connect("localhost","root","","BOOKSHOP");
//2. check the connection
if($db==false){
echo "Database connection fail!<br>";
echo "Error: ".mysqli_connect_error($db);
}
else{//if can connect
//echo "Yeay... Connected to database<br>";
//extract the search term
$title=$_GET['txttitle'];
$year=$_GET['cmbyear'];
//3. sql command to SELECT all data
$sql="SELECT * FROM books " .
"WHERE title LIKE '%$title%' ".
"AND year='$year'";
//4. send sql command to database server
$rs=mysqli_query($db, $sql);
//5. display records
if ($rs==false){
echo "SQL Error".mysqli_error($db);
}
else if($title==NULL){
//if no input on title field
echo "Please enter the book title";
}
else if(mysqli_num_rows($rs)==0){
//if no record matched
echo "Sorry, NO Book matched<br>";
echo "Search term - Title: $title; year: $year<br>";
}
else{//there is(are) record(s) found
//table header
echo "Search result - Title: $title; year: $year<br>";
echo "<table border=1>";
echo "<tr><td>ISBN</td>".
"<td>Title</td>".
"<td>Author</td>".
"<td>Publisher</td>".
"<td>Year</td>".
"<td>Quantity</td> </tr>";
while ($record=mysqli_fetch_array($rs)){
echo "<tr>";
echo "<td>".$record['isbn']."</td>";
echo "<td>".$record['title']."</td>";
echo "<td>".$record['authorid']."</td>";
echo "<td>".$record['publisherid']."</td>";
echo "<td>".$record['year']."</td>";
echo "<td>".$record['number']."</td>";
echo "</tr>";
}
echo "</table>";
}
}
?>
</body>
</html>
EXERCISE 3: Application - Insert Record into a Table
Create a page to receive user’s input (as in the image below). Insert to the Table BOOKS all the information provided by the user in the form. Provide the appropriate message to inform the user whether the record has been successfully saved or else.
Use the BOOKSHOP database structure as above.
