Poll system as a PHP Smarty plugin

This is a small project (1-2 days for a good coder), but you must have: * PHP with *Postgresql database* * knowledge of the Smarty template system for PHP [login to view URL] - this is important because you will be writing a Smarty plugin [login to view URL] I would like a poll system like described in this tutorial: [login to view URL] This page has a lot of code examples and a nice graphic - this should cut your work down a lot! WHAT IT WILL DO =============== It will be a piece of code using PHP and Smarty (a 'Smarty Plugin') that can be invoked from a Smarty template, which displays a poll such as: "Do you think you can do this project? ( ) Yes - Definitely ( ) No - not at all ( ) Maybe ( ) Not sure, hmmm" If the user clicks, they get to see the percentages that other people have answered, with a bar graph (see above link). Then their IP address $_SERVER['REMOTE_ADDR'] is recorded so that they cannot vote _on this poll_ again for 24 hours. There are two systems (poll admin, and poll participant) ADMIN MODE ========== The poll admin can: * create a poll (give it a name), set a start date +time (or 'immediately'), set an end date (or 'never') * add options to the poll (e.g. "yes definitely", "no - not at all", "maybe", "not sure") * edit/delete options * view how many times a poll has been displayed * view how many people have clicked the poll and numbers of results (and percentages %) * suspend a poll (turn it off) * resume a poll (turn it back on) * see a list of previous finished polls, how many people answered, and what the results were The poll admin can also create _groups of polls_. Polls in the same group are randomly shown, until all the polls in that group have been answered by the person. POLL PARTICIPANT (USER) MODE ============================ A page will include the poll code using the Smarty {include} statement and specifying which *poll group* should be displayed e.g. {poll group="logged_in_users_polls"} * A poll from this group is randomly chosen - but: * it _must not_ be a poll that the user has already answered * it must be enabled * it must be within the start and end times * If the user has already been shown all the polls in this group, the results from a randomly selected poll in this group are shown If the user answers the poll by clicking on one of the options, the result is sent to a PHP page. This page: * records the answer in the poll results and updates the statistics * checks the HTTP_REFERRER and returns to the page which included the poll (the referrer) using header("location: $referrer") * the referrer page (which includes the poll code) will display the result _for this poll_ (not a random poll) so that the user can see the results for the poll they have just answered * If they refresh the page after this, they may see another poll (as long as there are polls left in this group) - otherwise they will see the result of a random poll in this group
