A very simple filebased guestbook for PHP-beginners. I wrote this guestbook due to a lack of a database. <br>A very nice feature is the search-engine-like number-of-pages indicator. As administrator, you can delete messages by checking boxes.<br><br>There is a new release (V1.0.1) out now. I fixed some bugs and cleaned up<br> some code.

Simple database application, using MySQL. Supports a customisable frontend and admin panel, index.php and gbookadmin.php included as examples. Actual display of messages is customisable by changing guestbook.msg.tpl, configuration variables are set in code.guestbook.php. The admin panel is by default non-protected. You will need to add your own check that a user is an admin. index.php :: Example frontend <?php //PROJECT guestbook //MODULE index.php //MODULEDESC Frontend (Test Page) require("code.guestbook.php"); $guesttpl= file_get_contents("guestbook.msg.tpl"); ?> <html> <head> <title><?php echo $title; ?></title> </head> <body> <h2>Welcome to My Guestbook!</h2> <br /> <a href="gbookadd.php">Add your message</a> <br /> <?php $db= InitialiseDB(); GetGuestbookMessages($guesttpl, $db); EndDB($db); ?> </body> </html> gbookadd.php :: example add new messages to gbook page <?php //PROJECT guestbook //MODULE add.php //MODULEDESC Add to the guestbook (Test Page) require("code.guestbook.php"); ?> <html> <head> <title><?php echo $title; ?></title> </head> <body> <h2>Add A Message</h2> <?php $db= InitialiseDB(); if(isset($_REQUEST["readytoadd"])){ AddGuestbookMessage($_POST, $db); } else PrepareGuestbookSubmissionForm(); EndDB($db); ?> </body> </html> guestbook.msg.tpl :: how messages are displayed FRAME<table width="100%" style="border-style:solid">MESSAGES</table>ENDFRAME MESSAGEHOLDER <tr> <td align="left"><b>AUTHOR</b></td><td align="right"><b>POSTDATE</b></td> </tr> <tr> <td>TEXT</td> </tr> ENDMESSAGEHOLDER gbookadmin.php : example admin panel <?php //PROJECT guestbook //MODULE gbookadmin.php //MODULEDESC Administration (Test Page) require("code.guestbook.php"); $guesttpl= file_get_contents("guestbook.msg.tpl"); ?> <html> <head> <title><?php echo $title; ?></title> </head> <body> <h2>Guestbook Admin</h2> <br /> <?php if(1){ //check if the user is an admin here.

New Version. This guestbook now includes a date/time stamp. The features as of this release are: 1) AutoLink, when a user adds their website or email to the guestbook, at creates links for the items so users can quickly use that information. 2) Security, No html or php code will work, aso no-one can show things like phpinfo, ect. 3) There are pictures 4) Its still dynamic (no blank fields) 5) about 10% faster 6) STILL NO DATABASE NEEDED 7) now logs, it creates a log and keeps the signers' ip# and date/time as well as browser and computer type. You can match the timestamps and see the data on the person who signed it. All this in a VERY easy to setup NO DATABASE guestbook, for free, go check it out. http://www.pyroxpro.com/guest.php
