Part IV - Error Checking

1) Are you sure that you can run php scripts on your server?  Check with your systems administrator to make sure.

2) Have you changed the permissions of the text file 'GuestBook.txt'.  Make sure their set so you can write to them.

3)  Check to see if you have any errors in your scripts.  Open up the script in your browser window by typing in the full url to the script on your server - If you receive an error message, then you've got a small syntax error in your script.  It's probably a missed ';' or a similar error.  Usually this reports a line number along with the error, this should give you a good start on where to find the error.  If their is a blank screen or a success message then the script is working. 

4) Verify all paths used and try to visually track the variables from the beginning to the end of the process.


This tutorial and script was created with simplicity in mind.  It's my hope that everyone can use this tutorial.  Once you have an understanding of the script it should be possible to develop new uses for it - such as an updateable news section, links or directory's, updateable articles section, and a million other items.  Hopefully at the very least you'll be able to add a Guest Book to your site after reading over this.

» Description: Hmm... what to say about this one? It's reminiscent of the closing notes of the opening music from the Three Stooges done in a church organ style with a closing cymbal crash. I'll give this one away gratis, but feel free to check out my free loops and potential upcoming license-mandated ones over in the respective part of Flashkit.
