Hi I am very new to PHP and was working through a tutorial to learn a little about PHP. I created a simple form that passes form variables to another page to be displayed. It's a coin counter that when the user enters certain amounts of different denominations of coins, it is then passed, added up and output.
I have all the code for both pages, and I dont get any errors, but the totals dont actually add. There is just "0" for the answers.
Here is what I have, please if anyone can tell me whats wrong and why, I would greatly appreciate it.
Here is my simple form:
<form action="fancyCoin.php" method="post">
<table>
<tr>
<th>Pennies:</th>
<td><input type="text" name="pennies" /></td>
</tr>
<tr>
<th>Nickels:</th>
<td><input type="text" name="nickels" /></td>
</tr>
<tr>
<th>Dimes:</th>
<td><input type="text" name="dimes" /></td>
</tr>
<tr>
<th>Quarters:</th>
<td><input type="text" name="quarters" /></td>
</tr>
<tr>
<td colspan="2" align="center"><input type="submit" value="Submit" /></td>
</tr>
</table>
</form>
Here is my code:
<table width="200" border="1">
<tr>
<th colspan="2">Coin Counter</th>
</tr>
<tr>
<th bgcolor="#CCCCCC">Denomination</th>
<td>Number</td>
</tr>
<tr>
<th bgcolor="#CCCCCC">Pennies</th>
<td align="right"><?php echo (int)$_POST['pennies'] ?></td>
</tr>
<tr>
<th bgcolor="#CCCCCC">Nickels</th>
<td align="right"><?php echo (int)$_POST['nickels'] ?></td>
</tr>
<tr>
<th bgcolor="#CCCCCC">Dimes</th>
<td align="right"><?php echo (int)$_POST['dimes'] ?></td>
</tr>
<tr>
<th bgcolor="#CCCCCC">Quarters</th>
<td align="right"><?php echo (int)$_POST['quarters'] ?></td>
</tr>
<tr>
<th bgcolor="#CCCCCC">Total Coins</th>
<td align="right"><?php echo $totalCents='pennies' + ('nickels'*5)+('dimes'*10)+('quarters'*25) ?></td>
</tr>
<tr>
<th bgcolor="#CCCCCC">Total</th>
<td align="right"><?php echo $total= ($totalCents/100) ?></td>
</tr>
<tr>
<th> </th>
<td> </td>
</tr>
</table>
