Jeg prøvde å teste den på maskinen, der når jeg trykte "vote" ville browseren laste ned filen "poll.php". Må jeg legge den ut på nettet før den skal fungere?

Om du ikke kjører webserver med php selv på din pc.. Så er du nødt til å laste den opp på en server med støtte for php før du kan se om det funker, ja..

 

 

damn... Purfiy var litt for kjapp der.. :p
