Simple Mini Poll class library (SimPoll)
Author: Ilir Fekaj
Contact: tebrino@hotmail.com
Date: January 9, 2004
Version: 1.0
Latest version: http://www.free-midi.org/scripts/
Demo: http://www.free-midi.org
This easy-to-use class library enables you to set up your own survey system in just few minutes.
Package includes dynamically generated form (with number of total votes), detailed result
page, view of old polls, administration page, check for repeated votes.
It's free for all purposes, just please don't claim you wrote it and if you like it
and find it useful please leave link on results page.
If you have any problems, please feel free to contact me.
Also if you use it, please send me the page URL.
INSTRUCTIONS:
1. Execute these queries on your database:
# Table structure for table `poll_check`
CREATE TABLE `poll_check` (
`pollid` int(11) NOT NULL default '0',
`ip` varchar(20) NOT NULL default '',
`time` varchar(14) NOT NULL default ''
) TYPE=MyISAM COMMENT='';
# --------------------------------------------------------
# Table structure for table `poll_data`
CREATE TABLE `poll_data` (
`pollid` int(11) NOT NULL default '0',
`polltext` varchar(50) NOT NULL default '',
`votecount` int(11) NOT NULL default '0',
`voteid` int(11) NOT NULL default '0',
`status` varchar(6) default NULL
) TYPE=MyISAM COMMENT='';
# --------------------------------------------------------
# Table structure for table `poll_desc`
CREATE TABLE `poll_desc` (
`pollid` int(11) NOT NULL default '0',
`polltitle` varchar(100) NOT NULL default '',
`timestamp` datetime NOT NULL default '0000-00-00 00:00:00',
`votecount` mediumint(9) NOT NULL default '0',
`STATUS` varchar(6) default NULL,
PRIMARY KEY (`pollid`)
) TYPE=MyISAM COMMENT='';
# --------------------------------------------------------
2. Copy and paste code bellow in separate files and name them as noted
3. Set up database connection parameters
4. Optionally you can change layout of form and results page
5. Create new poll by starting admin page (in this case test_poll_admin.php)
6. Activate your poll by clicking ACTIVATE
7. Enjoy and send me your comments
