if ($view == donate) {
print "Please donate to a player, and help it out financially.";
print "<form method=post action=donate.php?view=donate&step2=donate>";
print "Donate <input type=text size=5 name=amount value=0> <select name=type><option value=credits>Credits</option><option value=platinum>Platinum</option></select>

You only had a mysql query updating ONE persons item amount when the item was transferred. You also didn't do your query right...you were updating the persons type with whatever amount was sent/given. You need to update it by adding/subtacting to what they have.

For example: If they have $1000 you want to do a query that says update money 1000+amount transferred for the person recieving the money.

many thanks i'll let you know if it works

[mandukar]

it works but it has a - infront of the money, which means its taken it away.. and the player can't spend money.

[mandukar]

I got it working, the - and + had to be swoped around. many thanks for the help :D

[mandukar]

another question...

how would I go about giving players money out of thin air kind of thing..

by using admin.php

give me a shout if you need the admin script.

[mandukar]

bumping up.

Just add the money to their total. i.e

$give = mysql_query("UPDATE MEMBERS SET CASH=CASH+$amount WHERE USERNAME='$username'");

[mandukar]

ok, would that go somthing like...

[quote]<?
if ($view == Give) {
print "tgive some members some money.";
print "<form method=post action=admin.php?view=give&step2=give>";
print "Donate <input type=text size=5 name=amount value=0> <select name=type><option value=credits>Credits</option></select>
<input type=text name=aid>
to player. <input type=submit value=give>";
print "</form>";
if ($step2 == give) {
if ($amount > $stat[$type]) {
print "You don't have enough $type.";
} else {
  mysql_query("update players set $type=$type-$amount where id=$stat[id]");
              print "You donated $amount $type to the player.";
$give = mysql_query("UPDATE MEMBERS SET CASH=CASH+$amount WHERE USERNAME='$username'");

            }
        }
      }
?>[/quote]

I am assuming admin.php is just a feature where you can add money to anyones accounts...so this is what you would do.

[code]

<?php

if ($_POST['give']){

$id = $_POST['id'];
$amount = $_POST['amount'];

mysql_query("UPDATE users SET money=money+$amount WHERE playerID='$id'");

echo "Successfully gave money to player #$id.<p>";

}

print<<<HERE

<form action="admin.php" action="post">

Player ID: <input type="text" name="id"><p>
Amount to give: $<input type="text" name="amount">

<input type="submit" name="give" value="Give Money">

</form>

HERE;

?>

[/code]

You might have to set the values in the UPDATE query to match your DB rows. Other then that, I hope this is what you are looking for ^^
