Converting Car mod v1 to v2

[lynm77]

Hello

Looking for some help if possible please i have attempted to convert the following car mob v1 to v2

But as always just have problems i can't figure out how to resolve.

First problem is with tune.php

Fatal error: Call to undefined function power() in /home/swisou/public_html/tune.php on line 9

 

<?php
include "globals.php";
print "<h3>Tuning Shop</h3><hr />
> <a href='garage.php'>Back To Garage</a><hr />";

$q=$db->query("SELECT cp.*,ct.* FROM cars_playercars cp LEFT JOIN cars_types ct ON ct.carID=cp.cpcCAR WHERE cp.cpcID={$_GET['id']} AND cp.cpcPLAYER=$userid", $c);
if($db->num_rows($q) == 0) { die("Invalid Car"); }
$r=$db->fetch_row($q);
$cost['acc']=$r['carACC']*power($r['cpcACCLV']+1,4)*($r['cpcACCLV']*$r['carACC']*10);
$cost['han']=$r['carHAN']*power($r['cpcHANLV']+1,4)*($r['cpcHANLV']*$r['carHAN']*10);
$cost['spd']=$r['carSPD']*power($r['cpcSPDLV']+1,4)*($r['cpcSPDLV']*$r['carSPD']*10);
$cost['shd']=$r['carSHD']*power($r['cpcSHDLV']+1,4)*($r['cpcSHDLV']*$r['carSHD']*10);
if($_GET['buy'])
{
if($_GET['buy'] != "acc" && $_GET['buy'] != "han" && $_GET['buy'] != "spd" && $_GET['buy'] != "shd") { die("Abusers suck."); }
$upgr_cost=$cost[$_GET['buy']];
if($ir['money'] < $upgr_cost) { die("You don't have enough money to tune this stat."); }
$db->query("UPDATE users SET money=money-{$upgr_cost} WHERE userid=$userid", $c);
$stat="cpc".strtoupper($_GET['buy'])."LV";
$db->query("UPDATE cars_playercars SET $stat=$stat+1 WHERE cpcID={$_GET['id']}", $c);
print "Car tuned!<br />

}
else
{
foreach($cost as $k => $v)
{
$costf[$k]='$'.number_format($v);
}
$acc=$r['cpcACCLV']*$r['carACC'];
$han=$r['cpcHANLV']*$r['carHAN'];
$spd=$r['cpcSPDLV']*$r['carSPD'];
$shd=$r['cpcSHDLV']*$r['carSHD'];
print "Current Stats for your {$r['carNAME']}<br />

Any help we be great.

Thank You

1. power() is a function, created by the modification creator, maybe they put it in global_func.php file.

2. global $db;

try pow() ?

Whilst you're probably right that pow() is what the mod creator intended, damn upgrading is going to get expensive on upgradeTypeLevel+1^4 alone. :|

Hello Lads

Thanks for your help worked one problem out with your ideas.

With the tune.php I added to top

function power($num1, $num2)

{

return pow($num1, $num2);

}

session_start();

Still trying to solve the carmarket.php

Cheers

function cmarket_index()

{

global $ir,$c,$userid,$h;

print "

Change the global, so it involves $db.

Hello Sniko

Yes that has worked.

Thank you for your help i changed to

function cmarket_index()

{

global $db,$ir,$c,$userid,$h;

print "
