Web Form to send messages in-world from a webpage
The following LSL script requests a new LSL Server public URL, then makes an HTTP call that updates a DB with the public URL of the script. A form read the URL from the DB and lets users send a message from a web page to the script.
It supports an automatic system to work around the dynamic URL problem. This requires a web hosting with PHP/MySQL support and a field in a database.
It sort-of works (only in a few sims on the beta grid!), but it's not complete yet; also, it's probably horrible code, I'm not a developer - don't use this if you don't know what you're doing.
LSL code
<lsl>
string my_url; key http_request_id; string base_url = "http://..../update.php?q="; // LA TUA PAGINA PHP
default
{
state_entry()
{
llRequestURL();
}
http_request(key id, string method, string body)
{
if (method == URL_REQUEST_GRANTED)
{
my_url = body;
llOwnerSay("chiamero' questo indirizzo: " + base_url + my_url);
llSetObjectDesc(my_url);
http_request_id = llHTTPRequest(base_url + my_url, [HTTP_METHOD, "POST"], "");
}
else if (method == URL_REQUEST_DENIED)
{
llOwnerSay("Errore: non ricevo il mio URL. " + body);
}
else if (method == "GET")
{
string text = llGetHTTPHeader(id, "x-query-string");
llSetText(text, <1,1,1>, 1);
llHTTPResponse(id,200,"OK!");
llSay(0, "sono stato chiamato da web");
}
else
{
llHTTPResponse(id,405,"Unsupported Method");
}
}
touch_start(integer total_number)
{
llOwnerSay("Il mio URL e': " + my_url);
http_request_id = llHTTPRequest(base_url + my_url, [], "");
}
http_response(key request_id, integer status, list metadata, string body)
