I have quite afew prolems with people putting negative numbers in the fields and it messes with my game, for example when they buy negative mercinates it floods the market with mercinarys and it they get gold they do not deserve...

here is the code please tell me to make it so they cannot put a negative number

<?
include "vsys.php";
if ($cgi['buy_merc']){
$merc=getCommonInfo();

if ($cgi['mercs_attack']){
if ($cgi['mercs_attack']>$merc->attackSpecCount)$cgi['mercs_attack']=$merc->attackSpecCount;
$gold=$cgi['mercs_attack']*$conf["mercenaries"]["atack"]["prise"];
$user=getUserDetails($_SESSION['isLogined']," gold ");
if ($user->gold>$gold){
updateMercenary(" attackSpecCount=attackSpecCount-{$cgi['mercs_attack']} ");
updateUser($_SESSION['isLogined'], " trainedAttackMerc=trainedAttackMerc+{$cgi['mercs_attack']} , gold=gold-$gold ");
}else{
$strErr="You do not have enough money";
}
}
if ($cgi['mercs_defend']){
if ($cgi['mercs_defend']>$merc->defSpecCount)$cgi['mercs_defend']=$merc->defSpecCount;
$gold=$cgi['mercs_defend']*$conf["mercenaries"]["defence"]["prise"];
$user=getUserDetails($_SESSION['isLogined']," gold ");
if ($user->gold>$gold){
updateMercenary(" defSpecCount =defSpecCount -{$cgi['mercs_defend']} ");
updateUser($_SESSION['isLogined'], " trainedDefMerc=trainedDefMerc+{$cgi['mercs_defend']} , gold=gold-$gold ");
}else{
$strErr="You do not have enough money";
}
}
if ($cgi['mercs_general']){
if ($cgi['mercs_general']>$merc->untrainedCount)$cgi['mercs_general']=$merc->untrainedCount;
$gold=$cgi['mercs_general']*$conf["mercenaries"]["untrained"]["prise"];
$user=getUserDetails($_SESSION['isLogined']," gold ");
if ($user->gold>$gold){
updateMercenary(" untrainedCount =untrainedCount -{$cgi['mercs_general']} ");
updateUser($_SESSION['isLogined'], " untrainedMerc=untrainedMerc+{$cgi['mercs_general']} , gold=gold-$gold ");
}else{
$strErr="You do not have enough money";
}
}
header("Location: mercs.php?strErr=$strErr");
}
?>

$str = str_replace("-","",$str);

Simplist way I can think of at this time.

hey, i have exactly the same problem, i have added the $str = str_replace("-","",$str); code into my mercs.php source code but it still allows the negative users to enter a negative number.

here is MY source code, hopefully this helps:

<?
include "vsys.php";
if ($cgi['buy_merc']){
$merc=getCommonInfo();

if ($cgi['mercs_attack']){
if ($cgi['mercs_attack']>$merc->attackSpecCount)$cgi['mercs_attack']=$merc->attackSpecCount;
$gold=$cgi['mercs_attack']*$conf["mercenaries"]["atack"]["prise"];
$user=getUserDetails($_SESSION['isLogined']," gold ");
if ($user->gold>$gold){
updateMercenary(" attackSpecCount=attackSpecCount-{$cgi['mercs_attack']} ");
updateUser($_SESSION['isLogined'], " trainedAttackMerc=trainedAttackMerc+{$cgi['mercs_attack']} , gold=gold-$gold ");
}else{
$str = str_replace("-","",$str);
$strErr="You do not have enough money";
}
}
if ($cgi['mercs_defend']){
if ($cgi['mercs_defend']>$merc->defSpecCount)$cgi['mercs_defend']=$merc->defSpecCount;
$gold=$cgi['mercs_defend']*$conf["mercenaries"]["defence"]["prise"];
$user=getUserDetails($_SESSION['isLogined']," gold ");
if ($user->gold>$gold){
updateMercenary(" defSpecCount =defSpecCount -{$cgi['mercs_defend']} ");
updateUser($_SESSION['isLogined'], " trainedDefMerc=trainedDefMerc+{$cgi['mercs_defend']} , gold=gold-$gold ");
}else{
$str = str_replace("-","",$str);
$strErr="You do not have enough money";

}
}
if ($cgi['mercs_general']){
if ($cgi['mercs_general']>$merc->untrainedCount)$cgi['mercs_general']=$merc->untrainedCount;
$gold=$cgi['mercs_general']*$conf["mercenaries"]["untrained"]["prise"];
$user=getUserDetails($_SESSION['isLogined']," gold ");
if ($user->gold>$gold){
updateMercenary(" untrainedCount =untrainedCount -{$cgi['mercs_general']} ");
updateUser($_SESSION['isLogined'], " untrainedMerc=untrainedMerc+{$cgi['mercs_general']} , gold=gold-$gold ");
}else{
$str = str_replace("-","",$str);
$strErr="You do not have enough money";

The number will always be positive.

take note to the last line :P
The number will always be positive.

okay, so where do i put that...
<?php
abs (-6) ;
//returns a value of 6

abs (12.4) ;
//returns a value of 12.4

abs (-456.2) ;
// returns a value of 456.2
?>

One reason the str_replace thing didn't work for you is that it was an example - you need to actually customize it to your site, by replacing $str with whatever variable it is that you want to be positive.

for the absolute value, if $var is the name of the variable you want to be positive, do this after the user puts his value in for it:

$var = abs($var);

(replacing $var with your variable name of course)

That's actually wrong. It should say that the number will be always non-negative.
