Creating a poll

   Frihost Forum Index -> Scripting -> Php and MySQL
 




KHO
Does anyone know a code to make a poll on a page with as many options as l want? l have to be able to coustomise all colors, and l would like to be able to store it in a seperate document and link to it so it doesn't increase load time for users. And it must only allow one vote per user, and it would be nice if l could set a value for each option already (l am transfering from a previous server and they hosted the poll so l can't take it with me)

Alright the template can be changed any time but I will do the main scripting part for you.
Here Is A PHP Poll.

Open Up phpMyAdmin and run the following code
Quote:
CREATE TABLE `poll` (
`id` int(11) NOT NULL auto_increment,
`question` varchar(40) NOT NULL default '',
`option1` varchar(30) NOT NULL default '',
`option2` varchar(30) NOT NULL default '',
`option3` varchar(30) NOT NULL default '',
`option4` varchar(30) NOT NULL default '',
PRIMARY KEY (`id`)
) TYPE=MyISAM AUTO_INCREMENT=3 ;

CREATE TABLE `pollvotes` (
`id` int(11) NOT NULL auto_increment,
`pollid` varchar(20) NOT NULL default '',
`vote` varchar(20) NOT NULL default '',
`username` varchar(50) NOT NULL default '',
PRIMARY KEY (`id`)
) TYPE=MyISAM AUTO_INCREMENT=11 ;



Name this file config.php
Quote:
<?php
$connection = mysql_connect("HOST",
"USERNAME",
"PASSWORD");
mysql_select_db("DB NAME", $connection);
$date = date("l, F jS, Y");
?>


Call this file newpoll.php
Quote:

With that use tables for each radio box / option.
That shouldwork.
