[SOLVED] make gold decrease when people buy wood

[berry05]

weird title i know but didn't know how else to explain this...lol

 

here's my html code..

<p>GOLD: 100</p>
<p>WOOD: 0</p>
<p>BUY WOOD:</p>
<p>
  <label>
  <select name="select" id="select">
    <option value="10">10</option>
    <option value="20">20</option>
    <option value="30">30</option>
  </select>
  </label>
</p>
<form id="form1" name="form1" method="post" action="">
  <label>
  <input type="submit" name="Submit" id="Submit" value="Submit" />
  </label>
</form>
<p> </p>

 

I'm trying to make it so when people buy wood there wood count goes up and there gold count goes down....it sounds easy but I'm kind of new to PHP.

<?php
if(isset($_POST['Submit']))
{
    $wood += (int) $_POST['select'];
    $gold = $gold - ($wood / $_POST['select'] *  5);//5 gold per piece?
}
else
{
$gold = 50;
$wood = 0;
}
?>
<p>GOLD: <?php echo $gold;?></p>
<p>WOOD: <?php echo $wood;?></p>
<p>BUY WOOD:</p>
<p>
<form id="form1" name="form1" method="post" action="">
  <label>
  <select name="select" id="select">
    <option value="10">10</option>
    <option value="20">20</option>
    <option value="30">30</option>
  </select>
  </label>
</p>
  <label>
  <input type="submit" name="Submit" id="Submit" value="Submit" />
  </label>
</form>
<p> </p>

Something like that might work, but next time try your self first.

[berry05]

ok i fixed it up a tad and now have this code...

<?php
if(isset($_POST['Submit']))
{
    $wood += (int) $_POST['select'];
    $gold = $gold - ($wood - $_POST['select'] *  10);//5 gold per piece?
}
else
{
$gold = 100;
$wood = 0;
}
?><style type="text/css">
<!--
.style1 {
font-size: 18px;
color: #FF0000;
}
-->
</style>
<p><span class="style1">YOU START OFF WITH 100 GOLD!</span></p>
<p>GOLD: <?php echo $gold;?></p>
<p>WOOD: <?php echo $wood;?></p>
<p>BUY WOOD:</p>
<p>
<form id="form1" name="form1" method="post" action="">
  <label>
  <select name="select" id="select">
    <option value="10">10</option>
    <option value="20">20</option>
    <option value="30">30</option>
  </select>
  </label>
</p>
  <label>
  <input type="submit" name="Submit" id="Submit" value="Submit" />
  </label>
</form>
<p> </p>

 

when i click submit when the thigns on 10 the gold goes down to 90 which is good...but when i choose 20 or 30 it gives the gold a large number...i want it so when i choose 20 the gold goes down by 20 and when i choose 30 the gold goes down by 30 ...i tried and i dont know what to do.. lol

try

<?php
if(isset($_POST['Submit']))
{
$wood += (int) $_POST['select'];
$cost_of_wood = 10;
$amount_of_wood = $_POST['select'];
$cost = $amount_of_wood * $cost_of_wood;
if($cost > $gold)
	echo "Not enough gold";
else
	$gold = $gold - $cost;
}
else
{
$gold = 100;
$wood = 0;
}
?><style type="text/css">
<!--
.style1 {
   font-size: 18px;
   color: #FF0000;
}
-->
</style>
<p><span class="style1">YOU START OFF WITH 100 GOLD!</span></p>
<p>GOLD: <?php echo $gold;?></p>
<p>WOOD: <?php echo $wood;?></p>
<p>BUY WOOD:</p>
<p>
<form id="form1" name="form1" method="post" action="">
  <label>
  <select name="select" id="select">
    <option value="10">10</option>
    <option value="20">20</option>
    <option value="30">30</option>
  </select>
  </label>
</p>
  <label>
  <input type="submit" name="Submit" id="Submit" value="Submit" />
  </label>
</form>
<p> </p>

 

It would be better to use sessions to store the amount of wood and gold though
