Please Demonstrate A Standard Trasaction Using NWE Variables

[DungeonMaster]

To avoid using typical PHP I will please like to see an example the NWE way to do the following :

Use a simple form and field to buy an orange and add it to the user's variable.

On a page you have

 

$orange = GetUserVariable(orange);
$cost = 2;

 

At present $orange = 0 now I need a simple form that enables me to input the number of oranges to buy at $cost and then do 2 things:

1. Add the number to $orange

2. Subtract the amount from currency

Thanks in advance.

ill have a go

 

if(isset($_POST["orangeQty"]) + 0)
{
//To make things easier on the eyes I will just make things its own variable
//For get user var @param1 is a constant which is the user variable name, @param2= A useridn if null it returns $userId by default
   $oranges = GetUserVariable(orange);
//Just for the beck of it I will demonstrate the config value, @param1=value name @param2=module name
   $cost = GetConfigValue("orangeCost","thisModule");
//This is just to make the deduction of money easier
   $updateCurrency = $_POST["orangeQty"] * $cost;
//See how much easier that is
   $userStats["!Currency"]->value -=  $updateCurrency;
//Now lets give the player his new orange amount. @param1 is a constant for the user variable name, @param2 will be what you are going to set param1 to, and param3 is just the same and get user variable param2 which is a userid for the user you are working with
   SetUserVariable(orange,$oranges+$_POST["orangeQty"]);
}
TableHeader("We are going to buy some Oranges");
echo "<table>";
echo "<form method='post' name='buyOrange"'>";
echo "<tr><td><b>How Many Oranges?:</b></td>";
echo "<td><input type ='text' name = 'orangeQty' value = '1' /></td></tr>";
echo "</form>";
echo "</table>";

TableFooter();
ButtonArea();
SubmitButton("Buy Orange","buyOrange");
EndButtonArea();

Pretty simple huh? Good luck ;)

Thank you very much Kyle. I will fit this in with my code and see how it works.

[KyleMassacre]

Anytime. Maybe on my blog I don't use I can set up some random stuff with NWE in there like little tuts or something

[DungeonMaster]

You are very helpful, thank you so much. I made some adjustment and that works for me well. I will be sure to open threads when I need further explanation as the Wiki is very sparse.

[KyleMassacre]

Yeah it took me a minute to figure out how to dial in the user variables. But please do post if you have any questions ill do my best to help when I can

BTW You could either use a uservariable or a stat. The stat could be a bit easier to work with and would have the advantage to be loaded all the time for you. All depends what you do with such "oranges" ;)
