nice work mrmajic!


What is causing your problem is $newhp variable. Somewhere something is wrong. Can you post your battle.php?

[mrmajic]

haha well i am having to fit them in my schedule here and there. Seems to be one of the busiest times for me right now but I think I can get one in tonight or tomorrow night maybe.

just to confirm, you are talking about the players hitpoints .. right?

yes, though I changed that to health... I'll probably change it back to hpoints just to make things easier...

hi,

i tried the script online, and i had one of my friends test out the scripts. . i saw that when he was playing the game, he could run the _add_items_to_shop.php script, so i made it so he couldnt run it if he was in the game ... something like this:

<?php
session_start();
if (isset($_SESSION['player'])) {

echo "You are not authorised to view this page!";
exit;
}
else
{
require_once 'connect.php';
$SQL = "INSERT into store(name, stats, statadd, price, amount, randid, type) VALUES ('Weak healing potion','hpoints','15','12','5','1','healing')";
mysql_query($SQL) or die("could not insert items");
$SQL = "INSERT into store(name, stats, statadd, price, amount, randid, type) VALUES ('Strong healing potion','hpoints','15','18','10','2','healing')";
mysql_query($SQL) or die("could not insert items");
$SQL = "INSERT into store(name, stats, statadd, price, amount, randid, type) VALUES ('Majic healing potion','hpoints','15','30','20','3','healing')";
mysql_query($SQL) or die("could not insert items");
echo "The following items were restocked into the shop: Weak healing potion, Strong healing potion, Majic healing potion";
}
?>


should this be ok??


Mr Majic...

[mrmajic]

ialso made a logout.php file:

<?php
session_start();
session_destroy();
echo "You are now logged out!";
exit(); ?>

so he just ran than to destory the session, then restocked the the shop then logged back in .. i think that i might have to make it so you can only log in x amounts of times a day .. that'll stuff him up

[hallsofvallhalla]

i would go beyond that and make a new field in the players table named admin...if admin then it equals 1

then in that script have it query the players but not select all, only select admin

$selectplayers = select admin from players where player = $player....ect...

then make a if statement

if $selectplayers[admin] = 1
{
run add item code
}
else
{
you are not an admin
}

[fleaky]

My randid never works i have to always for everything put in a manual id for everything evan the md5?? and i haven't done anything wrong.

[hallsofvallhalla]

sounds like you have, I think it might be a database field type issue. Y9ou can export the database as a file and send it to me if you want, then zip up your project and I will take a look.

[adamrain]

its beautiful i wise icould script like you.

btw when have you started learning it? 3years ago?
