Had issues with the script Jerret put on Classic iPhone so made my own adaptation which provided some error checking. Depending on jerrets next version, will either improve this or implement changes to his next version.
This is based on what Jerret created but ended up starting from scratch using his as a reference point while scripting with style I am used to. Made my version as a backend, allowing for a simple frontend to be created. Provided example of NPC commands (RC) but can be adapted to be done anywhere.
Ultimately should move the hasright checking to DBNPC itself but that's for the next version =]
PHP Code:
function onCreated() {
const ipbantick = 60;
setTimer(1);
}
function onTimeout() {
for (ip : this.ipban.getdynamicvarnames()) {
if (this.ipban.(@ip)[0] == "permanent")
continue;
this.ipban.(@ip)[0] -= ipbantick;
if (this.ipban.(@ip)[0] <= 0)
unIPBan(ip,"Released by the system","system");
}
setTimer(ipbantick);
}
/* Add/Modify an IP ban */
public function IPBan(ip, time, comment, admin, overwrite) {
/* Work out ban time */
temp.ban = banTime(time);
if (temp.ban[0] == 0)
return "Invalid time specified: "@time;
/* Check IP given */
temp.check = checkIP(ip);
if (temp.check[0] == 0)
return temp.check[1];
if (comment = "")
return "Must provide a reason for the IP ban";
//Checks done: lets ban an IP!
temp.ipstring = iptostring(ip);
if (this.ipban.(@ipstring).size() > 2)
{
if (!overwrite)
{
temp.ret = format("%s has already been banned. Set overwrite as true to overwrite this entry",ip);
return temp.ret;

this.ipban.(@ipstring) = new[4];
