Build part of a web site

Hi there, I've this "small" idea in my mind and I'd like to transform it in something real. Web pages, usable also with mobile devices: It is a sort of “old school MUD game”, but for fitness purpose. I live in this town with zillions of steps and dozens of asphalt road/trail connections. I want to create an interactive path generator for my friends and people of the town who wants a workout program. How it works? You choose a starting point then you move through "rooms" via http links, every room represent a piece of the town, precisely a stair, a road, a path and so on. Every room have it's own specs and these specs will be added to the "User workout stats". These specs($variables) are: .$ID [the room unique ID, for linking, ex: "CN001" "CN002" "SG001"] .$TITLE [a title for the room, ex: "Church St part 1 of 5"] .$DESCRIPTION [ex: "you are at the bottom of Church St...."] .$STEPS [number of steps on that room (up to next room), ex: "230"] .$ROAD [meters of road in that room (up to next room), ex: "500"] .$PATH [meters of path/trail in that room (up to next room), ex: "1200"] .$LENGHT [meters of workout in that room (up to next room), ex: "1100"] .$DROPUP [ + diff in height of the room (up to next room), ex: "13"] .$DROPDW [ - diff in height of the room (up to next room), ex: “-13”] .$LOCHEIGHT [height of the room (up to next room), ex: "162"] .$GEOLOC [GPS Position of the room, used only for the 1st & last room] -$variables for user stats- .$TOTSTEPS [total number of steps done in the "workout", ex: "12230"] .$TOTROAD [total meters of road done in the "workout", ex: "1500"] .$TOTPATH [total meters of path done in the "workout", ex: "1700"] .$TOTLENGHT [total meters of "workout", ex: "18000"] .$TOTDROPUP [total + difference in heights of “workout”, ex: “1550”] .$TOTDROPDW [total - difference in heights of “workout”, ex: “-550”] .$LOCHEIGHTSTART [height level start point of the workout] .$LOCHEIGHTEND [height level start point of the workout] A direct example: ==home page== [$ID=HOME] the user have to insert some data (for profiling purpose: name, email…) and then choose the starting point (a simple menu or a simple map should be ok for this purpose) ==chosen starting point== [$ID=CN001] -get variables of the room- .$ID=CN001 [get from DB or text file] .$TITLE=Church plaza [get from DB or text file] .$DESCRIPTION=Center of church plaza [get from DB or text file] .$STEPS=0 [get 0 because is the start point] .$ROAD=0 [get 0 because is the start point] .$PATH=0 [get 0 because is the start point] .$DROPUP=0 [get 0 because is the start point] .$DROPDW=0 [get 0 because is the start point] .$LOCHEIGHT=150 .$GEOLOC=42.12.12 -set variables for user stats- .$TOTSTEPS=0 [set 0 because is the start point] .$TOTROAD=0 [set 0 because is the start point] .$TOTPATH=0 [set 0 because is the start point] .$TOTDROP=0 [set 0 because is the start point] .$TOTDROPUP=0 [set 0 because is the start point] .$TOTDROPDW=0 [set 0 because is the start point] .$TOTLENGHT=0 [set 0 because is the start point] .$GEOLOCSTART=42.12.12 .$LOCHEIGHTSTART=150 -text of the room- hi $user, this is your starting point: //the whole description about the place with some useful information// “1/2 town” neighbourhood, is the center of the town, choose your next step from the below choices: -let the user choose next “room” of workout- go to east [$ID=CN002], you’ll find many stairs along the asphalt road; go to south [$ID=CN003], along the asphalt road, 1st crossroad after 1km; go to west [$ID=CN004], along the asphalt road, 1st crossroad after 2km; go to north [$ID=CN005], 212 steps before next crossroad.
