I found an old php/mysql tutorial where apparently the origional author no longer is arround to answer questions or provide assistance. So I am hoping someone on these forums could help.
The below code connects to a mysql dbase gets a players current lonitude and latitude in a game and then display’s where they are located via cross hairs on a game map.
There are also 4 html form buttons on the page to enable the player to move up down left right on the map. So when I go to the page and click one of the buttons I can see the blue cross hairs move. But after a few clicks of any of the buttons the cross hairs seem not to move any further. I am not sure if its an issue with the script not having the correct map size to useas there is a “gamesize” column in the mysql that is set to 250 but when I change it to some other larger or even smaller number the map gets all messed up and the cross hairs wont move at all.
So I am hoping by chance maybe there is just a coding error
here is my code
[code=php]
//lets get the players current lat and lon location to start out at
$sqllatlon = mysql_query(“SELECT map_lati, map_long from player_profiles where pid=’$mypid'”);
$latlonrow = mysql_fetch_array($sqllatlon);
$current_lat = $latlonrow[‘map_lati’];
$current_lon = $latlonrow[‘map_long’];
//lets update the map display
$brx = – $gamesize – $current_lon + 200;
$bry = – $gamesize + $current_lat + 200;
if ($current_lat < 0) { $current_lat = $current_lat * -1 . “S”; } else { $current_lat .= “N”; }
if ($current_lon< 0) { $current_lon = $current_lon * -1 . “W”; } else { $current_lon .= “E”; }
