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
April 26, 2008,
89,569 views
I will get started with this tutorial straight away. So lets build some HTML to show our form. We will do the HTML for displaying the posts of the guestbook at a later stage. So in order to make our form do this:
1. Make a new folder somewhere on your webserver and call it templates. I am working in the folder called guestbook, so it looks like ‘/home/guestbook/templates/’.
2. Next make a file in the templates folder and call it form.php.
3. Open up the file and put this code in:
<form name="guestbook" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" class="guestbookform"> <table width="100%" cellpadding="0" cellspacing="0" border="0"> <tr> <td valign="top">Name:*</td> <td valign="top"><input type="text" name="name" /></td> </tr> <tr> <td valign="top">E-Mail:*</td> <td valign="top"><input type="text" name="email" /></td> </tr> <tr> <td valign="top">Website:</td> <td valign="top"><input type="text" name="website" /></td> </tr> <tr> <td valign="top" colspan="2">Message:</td> </tr> <tr> <td valign="top" colspan="2"><textarea name="message"></textarea></td> </tr> <tr> <td valign="top" colspan="2" align="center"><input type="submit" name="submit" value="Sign Guestbook" /></td> </tr> </table> </form>
This code should be fairly self explanatory. Most of it is just simple HTML code that first declares how the browser passes data to the server (POST) and sets up the user interface elements. The only php in this code is in the action of the form, which tells where the browser should send the request to:
<?php echo $_SERVER['PHP_SELF']; ?>
This simply accesses a predefined PHP variable, which spits out the location where the user currently is. So if you were looking at the page we made in the browser it would output ‘form.php’.
Now if you just looked at the form.php page in your browser you will notice it looks bad. Lets get into the styling of the form before we start giving it some functions. We will achieve this by using a main skin template. This can be achieved simply through a file called skin.php which allows you to simply add bits of code to different sections of the HTML.

It go not me. It always write this errors:
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /3w/wz.cz/m/medvede/5/includes/actions.php on line 3
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /3w/wz.cz/m/medvede/5/includes/functions.php on line 12

i have it on http://medvede.wz.cz/5/index.php
Help me, please.
thank you
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.
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.
I have in config.php this code:
$host = ‘mysql.webzdarma.cz’;
$username = ‘medvede48′;
$password = ‘xxx’;
$dbname = ‘guestbook’; – - I try also entries
$email = ‘[email protected]’;
$connect = mysql_connect($host, $username, $password);
$dbselect = mysql_select_db($dbname);
$items = 10;
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
I have it on: photoshopsk.wz.cz
password: 7754705
I have files from this tutorial.
And your username for me to log in please?
(https://www.webzdarma.cz/)
My username on FTP is : photoshopsk.wz.cz
and password: 7754705
(https://www.webzdarma.cz/mysql/index.php)
And username on mysql server is: photoshopsk
password:ragp3s
Those settings do not work.
I need username, password, and address.
Otherwise i cannot look for you.
Look you:
1) http://photoshopsk.wz.cz/1/1.JPG
2) http://photoshopsk.wz.cz/1/2.JPG
3) http://photoshopsk.wz.cz/1/3.JPG
Do you thing this or no?
If no this, then what you think? What of address?
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!
@ 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?
My action what I make.
1.) I am download this tutorial: http://www.jotlab.com/wp-content/uploads/2008/04/guestbook.zip
2.) I give it on a web all. (http://photoshopsk.wz.cz/)
3.) I am create 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:

4.) I chanqe in config.php on it :
AND IT NO GO.
You know where is mistake???
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!
Hello there.
It doesn’t work at myhomepage.. Can you please tell me, what I’ve done wrong?
- Lily.
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
What do you mean with the correct FTP details or cpanel details?
However you upload the files to your server,
so i can see what the problem is. Because i cant replicate it
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.
Yep,
what sql did you change?
the connection settings?
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

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.
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,
Hi voidet,
I like the icons you use to identify the country, OS and browser. How did you do that?
Firestats plugin mate
Nice guestbook. I like it.
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!!
I havent read the code in detail but wouldnt it be better to do the error handling client side ?.
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.
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!
Hey,
Simply go into phpmyadmin and delete the entry in the banlist that is associated with your IP address
Thanks for the comments!
This form needs CAPTCHA security image.
GL.
Just want to see what kind of icon there is for Linux…
google
plenty there!
you can delete my posts now, i needed to know if this supported line breaks, which it does.
thanks
Hi:
Where is the tutorial? Do I have to login to see it or I’m just blind. Thank you.
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
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
Thanks,
VoiDeT
the same problem i got the error
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in C:AppServwwwgbincludesactions.php on line 3
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.
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
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!
Great tutorial, thanks a lot for your contributions. I’m newbie in php subject…
so it’s very useful for me…
i have the same problem:
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/a9819450/public_html/includes/actions.php on line 3
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.
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

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/blazesa/public_html/chamvil/guestbook/templates/entries.php on line 15
the actual code, in order…..
$spamip = mysql_num_rows($query);
$rows = mysql_num_rows($query);
$rows = mysql_num_rows($query);
while($row = mysql_fetch_array($query)){
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 ;
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
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
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/blazesa/public_html/chamvil/guestbook/templates/entries.php on line 10
Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/blazesa/public_html/chamvil/guestbook/templates/entries.php on line 15
But that I change my $dbname to username_guestbook and it works fine. Thanks for the great tutorial. I successfully have created mine.. =)
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!
Hello Friend,….
Thanx for the nice tutorial its working……
add more matter like this ….
we all are very thankful to you..
Bye
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!
VoiDeT
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?
Dennis
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!
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:xampphtdocsguestbooktemplatesentries.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.
Hi
First great thanks to the author of this tutorial/workshop
Its working great. But there is only a single problem with the website links in the db entrys they re not working.
The link includes the hole file path i.e.(http://htdocs/mywebsite/www.pcsh.it) whats wrong?
thx in advance and best regards
Oli
THX a lot
love this tut

Dude, many thanks for this nice and clean tutorial. Took me about an hour to read it all up and add own commands.
Hi!
Great guide! Many Thanks!
I use it on this page: “(http://www.lindesbergskateboard.se/Gastbook/guestbook/index.php)”
I have a problem, when I have posted something and then refresh the page it posts again without Im pressing the submit button. Probably just a silly code error from my side but could you please help me?
hello … thanks for the guestbook is very nice … but I have a problem.
basically when someone writes a message, I receive the email the new user who has written, but the message is displayed on the screen …. why?
thanks in advance ….
Amazing Tutorial. thanks. I have added free captcha, fully working if your interested I can let you have a link
Cheers again
Dan

by the way the first time i saw any kind of web coding in my life is when i looked at your tutorial
i am very desperate about this. waiting for your help. thanks

Wow! Finally I got a web site from where I know how to actually obtain helpful data concerning my study and knowledge.
Nice code…N design. I m using this code in my site….
I like. and thank u. so much for this code and design.
Please visit the website I entered above. These are the errors I am getting. I have been through your tutorial many times and can not see where I went wrong. If you have a few minutes and might be able to give me suggestions I would appreciate it. I am willing to also email the files so you can read the direct code.
I really appreicate your assistance. This guestbook turtorial is awesome, just wish I could figure out where I went wrong.

JJ
Got this working. But messed up something.
The only time I can see the messages is when I don’t fill the form right.
then the first box shows up with high lighted boxes. Then the entries below that. The a duplicate first box shows up. Any clue?
Thanks.
Does your site have a contact page? I’m having problems locating it but, I’d like to shoot you an e-mail.
I’ve got some recommendations for your blog you might be interested in hearing. Either way, great blog and I look forward to seeing it develop over time.
