Requirements:
- PHP 4+
- MySQL 3+
To start with we need to make a table for storing the guestbook entries, heres how you table structure should be:
Code:
CREATE TABLE `guestbook` ( `entry_id` INTEGER(6) UNSIGNED NOT NULL AUTO_INCREMENT, `fname` VARCHAR(45) NOT NULL, `location` VARCHAR(45) NOT NULL, `email` VARCHAR(60) NOT NULL, `dt` DATETIME NOT NULL, `comments` TEXT NOT NULL, PRIMARY KEY(`entry_id`) ) TYPE = MYISAM;
File gbook.php :
This file will have 2 sections one which collects the form data and the other which shows the form if no data was posted.
This is how we will do it :
PHP Code:
if(isset($_POST['type']))
{
//insert into database
}
else
{
//show the form
}
Lets look at the if block first, heres what all it needs to do :
- Collect the form data into some variables
- Connect to the MySQL server
- Build the SQL query
- Execute the query
- Show the user a message
Here goes the code :
PHP Code:
//collect the posted data
$name=addslashes($_POST['fname']); //addslashes escapes the single quotes
$location=addslashes($_POST['location']);
$email=trim($_POST['email']); //trim removes the leading and trailing whitespaces
$comments=addslashes(nl2br($_POST['comments'])); //nl2br converts the newline characters to <BR/>
//connect to the database
$link=@mysql_connect("localhost","pradeep","password") or die("Could not connect : ".mysql_error());
//@ sign demystified :- the '@' tells the parser not to show any warnings
//select the database to use
@mysql_select_db("db",$link) or die("Could not select DB : ".mysql_error());
//build the query string
$sql="INSERT INTO guestbook(fname,location,email,dt,comments) VALUES('$name','$location','$email',NOW(),'$comments')";
//execute the query
@mysql_query($sql,$link) or die("Could not execute : ".mysql_error());
//show the user some message
echo "<h3>Your entry was successfully inserted into the database,<br/>Thank you.</h3>";
//close the mysql connection
mysql_close($link);
}
File showgbook.php
This file will show the guestbook entries, heres what all it needs to do:
- Connect to the MySQL server
- Bulid SQL query
- Execute the query and fetch the resultset
- Loop through the resultset and display each record in a format
Here the SQL query :
PHP Code:
$sql="SELECT fname,location,email,UNIX_TIMESTAMP(dt),comments FROM guestbook ORDER BY dt";
PHP Code:
while($row=mysql_fetch_array($result)) //loop and fecth a single row everytime
{
echo "<br><table style=\"border:#666666 1px solid;font-family:Georgia;font-size:14px\">" ;//print the table tag into the page
echo "<tr>";
//we will display the name ans date of signing in the first row of the table
echo "<td bgcolor=\"#666666\"><font color=white>Signed by ".$row[0]." on ".date("l dS of F Y h:i:s A",$row[3])."</font></td></tr>";<br>
echo "<tr><td>Location : $row[1]</td></tr>";
echo "<tr><td>Email : $row[2]</td></tr>";
echo "<tr><td>Comments :<br> $row[4]</td></tr>";
echo "</table><br>";
}
Hope you enjoy making your own guestbook.
