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 = ‘your@email.com’;
$connect = mysql_connect($host, $username, $password);
$dbselect = mysql_select_db($dbname);
$items = 10;

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!

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
By Lily
on Jun 12, 2008
What do you mean with the correct FTP details or cpanel details?
By VoiDeT
on Jun 12, 2008
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.
By VoiDeT
on Jun 12, 2008
Yep,

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,

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 ?.
By VoiDeT
on Aug 12, 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.

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!
