Ultimate Guestbook Tutorial: How to build a Guestbook with a honeypot, error checking, IP banning, pagination, e-mail notification and smilies with PHP and mySQL

Meta: April 26th 2008 // PHP // 44,664 views

We’re now at the final stage of our tutorial, pagination. Pagination are those things at the top/bottom of page which allows you to jump to segments of pages. On google you have pagination, page 1, 2, 3, 4, 5 etc. As do you on this website. We will have the same thing for our guestbook; but instead of 1,2,3,4,5 we will have 1-10, 11-20, 21-30 etc. To show blocks of 10 entries. Trust me, you don’t want 2000 guestbook entries on a single page.

Lets being! Open up skin.php and:

Find:

<tr>
		<td valign="top"><?php include('entries.php'); ?></td>
	</tr>

Above it add:

<tr>
		<td valign="top" align="center"><?php pagination($_GET['page'], $items); ?></td>
	</tr>

Correct. We will be using a function for this! But before we make the function, we need to do some setting up. Open up entries and:

Find:

$query = mysql_query("SELECT *, UNIX_TIMESTAMP(`date`) as date FROM `entries` ORDER BY `date` DESC");

Replace it with:

$query = mysql_query("SELECT *, UNIX_TIMESTAMP(`date`) as date FROM `entries` ORDER BY `date` DESC LIMIT ".$page.",".$items."");

This adds in a limit, where we will be able to get a certain number of items, with a certain starting point. For example, we only want to select 10 items after the first 5 items. This lets us do it. We have inserted some variables here, which will automatically calculate what needs to be fetched. So to do so add above it:

if(!isset($_GET['page'])){
		$page = 0;
	} else {
		$page = $_GET['page'] * $items;
	}

This looks at the address bar, and gets the value of ‘page’. We will be setting a numerical value for page. But what about the $items variable. Well this will be how many items we want to display on the page. I stored this value in the config.php file. So open up your config.php file which we put in the includes directory and add:

Add:

$items = 10;

Underneath:

$connect = mysql_connect($host, $username, $password);
	$dbselect = mysql_select_db($dbname);

Excellent! You can try this out straight away. Simply by going to the url and typing in page=1 or what not in the get component of the address bar:

http://www.yourdomain.com/index.php?page=1

Next we want to show some pagination, so that our users can simply click on some page numbers and get taken to the right spot, instead of typing a number up in the address bar. For my pagination i want it to have a link to go to the very first page, and to the very last page. I also want the page numbers to display a range of posts, and not simply a page number. Also i want to know what page i am on, and in turn it should show a different style for the current page. For this we will use another function, so open up your functions.php file and add:

function pagination($page, $items){
		$query = mysql_query("SELECT * FROM `entries`");
		$rows = mysql_num_rows($query);
		$pages = ceil($rows / $items);
		echo '<a href="'.$_SERVER['PHP_SELF'].'?page=0"><<</a> ';
		$tabs = 2;
		for($i=$page-$tabs; $i <= $page+$tabs; $i++){
 
			if(($rows - ($i * $items)) <= $rows && ($rows - ($i * $items)) > 0){
				if(($rows - (($i+1) * $items)+1) < 0){
					$top = 1;
				} else {
					$top = ($rows - (($i+1) * $items)+1);
				}
 
				if($page == $i){
					echo '<span>'.($rows - ($i * $items)).'-'.$top.'</span> ';
				} else {
					echo '<a href="'.$_SERVER['PHP_SELF'].'?page='.$i.'">'.($rows - ($i * $items)).'-'.$top.'</a> ';
				}
			}
		}
		echo '<a href="'.$_SERVER['PHP_SELF'].'?page='.($pages-1).'">>></a> ';
	}

Taking a deep breath? Me too. Let me explain line for line what is going on here. Using the line numbers above:

1: We have touched on functions before. This is no exception. This simply sets up the pagination function, with 2 parameters. This allows us to get the current page and how many items was set in the config.php file. Simple.

2-3: These lines simply select everything in the database and then count up how many rows were returned. This is done so that we can track the page titles, i.e. 51-42, 41, 32 etc.

4: The ceil function and the equation inside is used to calculate how many pages there are. This component would usually get used alot, however for this style of pagination we are only using it once, and that is on line 23.

5: This line sets up the first link, and that is the link to be taken to the newest posts. Notice how we simply create a hyperlink to page 0. That tells the SQL statement back on the entries.php page to select 10 items (set in the config.php file) starting from 0*10, which of course equals 0, so starting from the start.

6: This is a variable that i set up to determine how many pages will be infront and behind of the current page in our pagination. What if we had 1million posts, and we would only limit 10 posts per page, we would have 100,000 links in our pagination navigation bar. Not good. So this way we have a max of 5 at a time, 2 in front, and 2 behind. You can change this to be lower or greater.

7: Now the fun begins. It sets up a loop. But pay attention to

$i=$page-$tabs; $i <= $page+$tabs;

This starts $i off at -2 (2 behind) and stops the loop at +2 the current page. Now you’re thinking what will happen when we get to the first and last posts, won’t extra page titles be displayed? Even negative pages? Well we have taken care of them inside the loop.

9: Does exactly this. It tests if the page is within the max and min pages possible. That way you will never see an option to go higher than the max page, or lower than the first post! This is done with an IF statement which can escape all the display code.

10-14: This section sets up the 2nd number in the pagination. I.e 1 – 10. It sets up the 10. This is for the pages that don’t match up to our defined $items number. For example the last page may only have 1 post on it. So we calculate this, see if it is 0 and if it is under 0 then it knows that this is the last page possible, and in turn will simply display a 1.

The other case simply gets the total number by seeing what value $i is, increasing it by one to match the page under the current page (we dropped its value by 2 remember) multiplying it by the $items, to show the post count, adding 1 to it, otherwise we get an overlap of posts, and then subtracting it from the amount of rows returned. If you didnt follow that, don’t worry. Just think of it as we had some lag, we need always a page lower than the current, but we need to add an extra post otherwise the posts will overlap!

16: Is our style tester. It tests to see if the page display is the one we are looking at in the browser. If it is, it removes the link and makes the text grey. Easy. If it isnt the one on the page, i.e. the two before or behind it, then it make it a link. That should be easy enough to follow

23: Does like on line 5. It shows the very last (oldest) post page!

Also the css for the pagination class is:

.pagination {
	font-size: 14px;
}

Nothing really but smaller text! But you can style it to how you want it.

Now i noticed a potential bug! What happens when you delete an item, say some idiot posted something you don’t like. Then you’re page numbers and post numbers would be totally messed up. Because if you remember, our post numbers were displayed with:

<td valign="top" align="right">#<?php echo $row['id']; ?> Posted on: <?php echo date("d/m/y g:i a", $row['date']); ?></td>

Correct, with the id of the table cell in our database. So lets go back and fix this. Open up your entries.php file and:

Under:

if(!isset($_GET['page'])){
		$page = 0;
	} else {
		$page = $_GET['page'] * $items;
	}

Add:

$query = mysql_query("SELECT * FROM `entries`");
		$rows = mysql_num_rows($query);

It has to be like above, above the other SQL statement.

Next find:

$i++;

Move it to the bottom of the page where you see:

</tr>
	<?php } ?>
</table>

So it looks like:

</tr>
	<?php $i++;} ?>
</table>

Next find:

<td valign="top" align="right">#<?php echo $row['id']; ?> Posted on: <?php echo date("d/m/y g:i a", $row['date']); ?></td>

Change it to:

<td valign="top" align="right">#<?php  echo $rows - ($page)-$i; ?> Posted on: <?php echo date("d/m/y g:i a", $row['date']); ?></td>

Excellent! Test it out if you like. Delete a record and see how it affects the way the items are numbered. That way you should never see a hole in your posts, i.e so it won’t look like 4,5,6,8,12 instead it will always be, 4,5,6,7,8,9,10,11,12. Get me?

Finished! Phew! Oh wait, one more thing? E-mail Notifications!

    Help me, please.
    thank you

  2. VoiDeT // June 02nd 2008

    Hey Vladis,

    Did you make sure you have created the database correctly?

    Please make sure you have done this, otherwise this error would definitely show up.

  3. VLADIS // June 03rd 2008

    I make this TABLE :

    CREATE TABLE `entries` (
    `id` int(8) NOT NULL auto_increment,
    `name` varchar(255) collate latin1_general_ci NOT NULL,
    `email` varchar(255) collate latin1_general_ci NOT NULL,
    `website` varchar(255) collate latin1_general_ci NOT NULL,
    `message` text collate latin1_general_ci NOT NULL,
    `date` timestamp NOT NULL default CURRENT_TIMESTAMP,
    `ip` varchar(15) collate latin1_general_ci NOT NULL,
    PRIMARY KEY (`id`)
    ) ENGINE=MyISAM DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci AUTO_INCREMENT=1 ;

    and this:

    CREATE TABLE `spam` (
    `id` int(8) NOT NULL auto_increment,
    `ip` varchar(15) collate latin1_general_ci NOT NULL,
    PRIMARY KEY (`id`),
    KEY `ip` (`ip`)
    ) ENGINE=MyISAM DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci AUTO_INCREMENT=1 ;

    I have in config.php this code:

    And it doesn’t go.

  4. VLADIS // June 03rd 2008

    I have in config.php this code:

    $host = ‘mysql.webzdarma.cz’;
    $username = ‘medvede48′;
    $password = ‘xxx’;
    $dbname = ‘guestbook’; – - I try also entries
    $email = ‘your@email.com’;
    $connect = mysql_connect($host, $username, $password);
    $dbselect = mysql_select_db($dbname);
    $items = 10;

  5. VoiDeT // June 03rd 2008

    Can you please provide me with your ftp details?
    It could be my end, or it could be your end. But i thought i tested this script without any rows in the database. Let me know

    Hi! I just want to say thank you for a wonderful tutorial. I will probably use this at my website when I have finished it, so I can send the link later. Thank you!

  12. VoiDeT // June 09th 2008

    @ Linnea – Thanks alot for your comment. I would love to see your website when you have finished with it!

    @Vladis – Doesn’t work dude. Maybe you have limited the IP range of access?

  13. VLADIS // June 11th 2008

    My action what I make.

  14. Amanda // June 11th 2008

    Hello. I am trying to make a wedding website and want to add a guestbook feature. Everything seemed to be working okay but now I get two big errors.

    Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/.magdalen/danfrancis/www/attempt/includes/actions.php on line 3

    and

    Fatal error: Call to undefined function: pagination() in /home/.magdalen/danfrancis/www/attempt/templates/skin.php on line 48

    Any clue what is going on? Any help would be great. The site it’s at right now (just testing it out) is: http://www.danfrancisphotography.com/attempt/index.php

    THANKS AGAIN!

  15. Lily // June 11th 2008

    Hello there.

    It doesn’t work at myhomepage.. Can you please tell me, what I’ve done wrong?

    - Lily.

  16. VoiDeT // June 11th 2008

    Hey people,

    I don’t know why you are having these problems. It sounds like an error in the SQL. I am happy to look on your server if you provide me with the correct FTP details or cpanel details.

    I have installed this script from the zip file and it works fine.

    Thank you

  17. Lily // June 12th 2008

    What do you mean with the correct FTP details or cpanel details?

  18. VoiDeT // June 12th 2008

    However you upload the files to your server,
    so i can see what the problem is. Because i cant replicate it

  19. Lily // June 12th 2008

    The only thing I’ve changed is the MySQL otherwise I haven’t touched anything. The same text as Amanda got I have at my page.

  20. VoiDeT // June 12th 2008

    Yep,
    what sql did you change?
    the connection settings?

  21. eHobayyeb // June 22nd 2008

    Amazing!

    Everything works fine.
    I am new PHPier and found many useful tips & tricks!

    Keep it up VoiDeT, I will do all PHP tuts here.

    Thanks

  22. HCF // July 05th 2008

    Hi, awesome tutorial, shows exactly how to use the basics. 2 questions regarding your techniques:
    1. What about using mySQLi instead of the usual mySQL (only PHP5, but way better), since it is faster and more secure.
    2. I guess this was designed for beginner and advanced user, so it would be useful to show a lil bit of object oriented programming, since it makes the source code more accessible and php more flexible.

    Awesome work, greetings from Germany.

  23. VoiDeT // July 05th 2008

    HCF!

    Vielen dank für ihre nette antwort. Du hast auf Englisch geschreiben, so ich werde auf Deutsch antworten. Es freut mich so viel das du die tutorial magst. So danke noch mal. Ich hab noch nicht viele mysqli probiert. Aber ich weiß das es OOP ist. Für dieser tutorial will ich sehr einfach machen, aber vielleicht lern ich MySQLi für meine selber projekte.

    Vielen dank noch mal,

  24. Fredrik // July 07th 2008

    Hi voidet,

    I like the icons you use to identify the country, OS and browser. How did you do that?

  25. VoiDeT // July 07th 2008

    Firestats plugin mate ;)

  26. Akira // July 30th 2008

    Nice guestbook. I like it. :)

  27. Dan Bunyard // August 09th 2008

    Awesome work! I have a guestbook on my existing site but….to put it mildly….it was hacked together to make it work. You have sure a great example here of the things you can do with PHP/MySQL. Keep up the great work, and happy coding!!

  28. Franklyn // August 11th 2008

    I havent read the code in detail but wouldnt it be better to do the error handling client side ?.

  29. VoiDeT // August 12th 2008

    Doing just client side opens you up to attacks.
    This is a server side tutorial anyhow. By just doing client side error checking would be insecure and negligent.

  30. mm // August 24th 2008

    hi – this is really a great tutorial. Im very glad you did this as I was confused about how to add a honeypot.

    listen, do you know how to add an ADMIN page/function to this GB, or is it already there? I was testing mine and managed to ban my own IP! I’m not sure how to manage the database at this point. Any help is appreciated.
    Thanks!

  31. VoiDeT // August 24th 2008

    Hey,

    Simply go into phpmyadmin and delete the entry in the banlist that is associated with your IP address :)

    Thanks for the comments!

  32. Yousha // September 11th 2008

    This form needs CAPTCHA security image.

  33. Pick Nick // January 30th 2009

    Just want to see what kind of icon there is for Linux…

  34. VoiDeT // January 30th 2009

    google

    plenty there!

  35. testinr666 // February 16th 2009

    you can delete my posts now, i needed to know if this supported line breaks, which it does.

    thanks

  36. John // February 26th 2009

    Hi:
    Where is the tutorial? Do I have to login to see it or I’m just blind. Thank you.

  37. Martin Murphy // March 05th 2009

    Hi m8 brilliant tutorial. Just wondering any way of putting the guestbook into the layout of your website? I cant quite get it right always goes into the wrong place :S

  38. VoiDeT // March 05th 2009

    Hey Martin!
    Thanks alot for the reply!
    After seeing some bad comments here from some brainless morons, you make me want to write more tutorials!
    I would need to see your page however, then i can give you some feedback on why it isn’t sitting correctly on your page :D Thanks,
    VoiDeT

  39. Norway // March 22nd 2009

    the same problem i got the error

    Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in C:\AppServ\www\gb\includes\actions.php on line 3

  40. VoiDeT // March 28th 2009

    Norway,
    Try putting some content into your database.
    I really should of built in more tests for this tutorial. However it was a tutorial, not a script give away. I will see if i get some free time soon to patch it up a bit more.

  41. weeman // March 29th 2009

    Hi
    Thanks for the great tutorial!

    I’m just wondering: How do I make a “new line”-character from the form show up as a new line in entries? Just like all entries in this guestbook we’re writing in now show up nicely formatted with new lines.

    new line
    new line
    new line

    instead of
    new line new line new line

  42. VoiDeT // March 30th 2009

    Doesn’t the guestbook show newline characters? I mean doesn’t the text drop down a new line? New line characters are written like “\n” or a return is “\r”. Thanks for the comments Weeman!

  43. Robi Santoso // May 12th 2009

    Great tutorial, thanks a lot for your contributions. I’m newbie in php subject…
    so it’s very useful for me… :)

  44. meg83 // May 20th 2009

    i have the same problem:

  45. Thomas Cherry // May 25th 2009

    I am also having a bit of trouble with setting this guestbook up. I think i’ve tracked the issue to ‘$query’, as this is the one thing that all the errors have in common. Please, i’m new to this. thanks.

  46. Thomas cherry // May 25th 2009

    ok cool, it has to do with the tables??? when i go into myphpadmin i see that there are no tables. could this be the problem….

    guestbook.sql

    CREATE TABLE `entries` (
    `id` int(8) NOT NULL auto_increment,
    `name` varchar(255) collate latin1_general_ci NOT NULL,
    `email` varchar(255) collate latin1_general_ci NOT NULL,
    `website` varchar(255) collate latin1_general_ci NOT NULL,
    `message` text collate latin1_general_ci NOT NULL,
    `date` timestamp NOT NULL default CURRENT_TIMESTAMP,
    `ip` varchar(15) collate latin1_general_ci NOT NULL,
    PRIMARY KEY (`id`)
    ) ENGINE=MyISAM DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci AUTO_INCREMENT=1 ;

    CREATE TABLE `spam` (
    `id` int(8) NOT NULL auto_increment,
    `ip` varchar(15) collate latin1_general_ci NOT NULL,
    PRIMARY KEY (`id`),
    KEY `ip` (`ip`)
    ) ENGINE=MyISAM DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci AUTO_INCREMENT=1 ;

  47. Thomas cherry // May 25th 2009

    well what do you know. i imported the ‘guestbook.sql’ file into the database using phpmyadmin and bingo, alls well that ends well…. thanks for the tutorial. it really helped me a shit load

  48. Ren // June 15th 2009

    Well, at first I have the problem:-
    Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/blazesa/public_html/chamvil/guestbook/includes/actions.php on line 3

    Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/blazesa/public_html/chamvil/guestbook/includes/functions.php on line 12

    But that I change my $dbname to username_guestbook and it works fine. Thanks for the great tutorial. I successfully have created mine.. =)

  49. VoiDeT // June 15th 2009

    I am getting alot of comments about mysql_num_rows errors!
    People, please check that you have the correct database connection settings in order and that your tables have been set up correctly!

  50. Tilak // June 16th 2009

    Hello Friend,….
    Thanx for the nice tutorial its working……

    Hello VOIDET

    I spent last night going through this tutorial and it was great and informative.

    One question I have is that I see your guestbook example has had some spambot action. Is this because there are new techniques that your tutorial doesn’t cover? I’d like to keep this kind of crap off my guest book if possible.

    Thanks for your great tutorial and your feedback.

    Best,
    CGar

    Hey Cgar,

    This is both true and unfortunate.
    I only taught one spam catching technique.
    However more can be applied if need be. Generating a captcha form, or having an ip-ban with 30 day cool off period. Running known ip blocking from black lists.
    The honey pot technique is just one! Surprisingly, it rejects quite alot!

    Let me know if i can help you out further!

    Hi there,

    A great tut! Im trying to put it on my site.

    But there is one little problem. The honeypot.. when is add this link:

    a new text field appears on my guestbook, while you where saying that it was hidden?

    How is that possible?

    Hi there. Thanks for the great tut. Sorry…forgot to read the last side, as I didn’t used all of the tut for my guestbook at the moment. So I implemented the guestbook in my website without asking you first. And…I’m not completly ready, still working on some things as the honeypot and the pagination.

    Hello VOIDET,

    This is the best tutorial on the internet so far! :D

    I’m stuck at stage 7 – 10,
    it looked fine until stage 7 then the succes-message never showed up. :(

    The IP thing didin’t work for me :/ so I jumped that part and now I’m trying to get the entries to work out, but it show me this message:
    Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in C:\xampp\htdocs\guestbook\templates\entries.php on line 6

    do you have a idea of what’s wrong?
    I would be happy for any help, just contact my email!

    Regards Zime

    @Zime:
    Thanks a lot for the kind words.
    That’s a shame that you can’t get the guestbook working. It looks as though your data isn’t being insert correctly. What you can do however is check your database for any records. If they aren’t in there then check what’s going on with data you’re inserting, and the insert commands.
    If you do see the data in there, then check what’s happening when you try and retrieve the records.

    I’m thinking i might rewrite this tutorial to use OOP with PHP5.
    Or maybe save that for a whole new tutorial.
