The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Reservation script - further modifications

Asked by rowby in Perl Programming Language

Tags: reservation, script

Hello class.

I need further modifications on the reservation script called by this page (it is not live on the site, so feel free to test:

http://www.laxautopark.com/reservations.shtml

(note the years are now hidden fields, and I added two fields phone and comments which are not "live" yet.

First the easy part. I want the two time fields ("Time you will arrive to park your car:" and "Time you will be returning to pick up your car:*" to have the am and pm's built in, as on the following page (which IS live):

http://foxrentacar.com/rates_reservations.html

Also, for some reason if you make a reservation for a date EARLIER than today's date at:

http://www.laxautopark.com/reservations.shtml

...you get the following message:

Can't locate object method "after" via package "current" at /home/sites/site24/web/cgi-bin/reservation.cgi line 151.

Now it *may* be I uploaded an earlier script but I doubt it. So please double check the script which I am posting at the end of this question.

Also if you put in your first name, last name and email address but do NOT enter a date and leave the rest of the form blank, you get the following message:

Day 'Day' out of range 1..31 at /home/sites/site24/web/cgi-bin/reservation.cgi line 134

I would rather a user friendly message appear.

Here is the script as is on the site:

#!/usr/bin/perl

print "Content-type: text/html\n\n";

use CGI;
use Time::Local;

## Full path to the sendmail file.
