PRO poll !!!

Auteur: sayanora - 25 mei 2005 - 20:24 - Gekeurd door: Mokka - Hits: 26462 - Aantal punten: 4.19 (27 stemmen)



Over PRO PoLL :
- Adminfunctie
- Archieffunctie
- Makkelijke installatie middels instal.php
- Radios worden automatisch gemaakt aan de hand van het aantal antwoorden, maw er zijn erg veel antwoorden mogelijk.
- Ip logging zodat er per poll maar 1x gestemd kan worden
- Grafische en procentuele indicator
- Polls makkelijk te herkennen aan weergegeven nummer en bijhorende datum

Installatie:
- Download of kopier de bestanden naar een map (bijv. poll)
- Verander in database.php de gegevens zodat ze op jouw db van kracht zijn.
- Open de browser en ga naar .../poll/instal.php en de SQL tabellen worden weggeschreven Let op! als de tabellen poll en/of votes al bestaan worden deze overschreven!
- Met de browser nog open ga je naar .../poll/admin.php en type je de vraag en de antwoorden gescheiden door een comma.
- Je poll is nu operationeel!
