Parcel access control from within a script

Hi all,

I have a bit of a problem, and can't think of a nice clean way of sorting it out.

Here's some back-ground:

I have written a little php application which enables a user to 'book' / 'reserve' a parcel of land through a little webpage. I've written an LSL script which talks to a MySQL database to determine if (at any point in time) that parcel has been reserved ... and who has access to it. So currently, I have set my parcel of land to 'no public access' ... so everyone sees the 'No Entry' sign around the land - if my parcel-manager script detects the person who made the booking (on the website) then they are granted access to the parcel. So, this means that only the person who has made a booking for the parcel has access to the parcel... - a simple reservation system.

OK, the problem is ... it works the wrong way around. What I really want is .... for the land to have public access ... a part from the times which are booked. So, normally anyone can visit and use the parcel. But, if someone has made a booking ... then only the person who has made the booking can have access (e.g. the public access is removed during the booking period).

So, what I would like to do is to control the public access attribute of a parcel of land from within a script ( in an object which resides in the parcel, and is owned by the same group which owns the parcel).

Does anyone have any ideas ? I've been looking through the LSL library / API and can't see (perhaps I can't see the wood for the trees ) a way of controlling the public access (I can see the 'Get' functions .... appears to not be any 'Set' functions though - grrrrr).

I've thought about trying to work-out the members of a group and adding all members to the access-list (but ... don't appear to be able to do this either). The only approach I can think of at the moment is sensing anyone near the parcel and granting them access (by default) and then removing access for a booking .... though this is really clunky --- I would very much rather not do this.... .... what I want to do is to control the public access attribute from within a script.

Please, if you have any ideas / approaches / experience of this type of problem ... please help - it would be very much appreciated.

Thanks in advance, Eli

The only way is closing the land and use this functions to manage the access on it.

Thanks Papalopulus - this is what I've been fearing ... it's going to make things a little 'clunky'.... Do you know (I haven't tried ... and need to experiment) if the ban list still operates with Public Access set ? .... perhaps the way to do it is to ban people which are not part of a booking (may be use a sensor to detect them) and reset the ban list once the booking is over (I think this is what you are suggesting ?)

Thanks. Eli

Yes if you has the land in open mode , you need to ban them or unban them to get access on it.

here you has an example from Void Singer using the funtion LlOverMyLand

hmmm I need to update that thanks, Papalopulus. the wiki link in the script now goes to the wrong page, and IIRC signing examples is discouraged.

PS. if you post in scripting tips, for scripting question you'll usually get more comprehensive answers to scripting questions, and probably a few off the wall ideas too.

Oppss!!
I forgot to say that
Void has right ,in that place you can get more answers
