Let me explain this as best I can. The user enters how many numbers he wants
to add. This form goes to another page. This page loops a form field and
it's name is "num" and after num is the number it is currently on. Here's
the code:
<form name="add" method="post" action="<?php $_SERVER['PHP_SELF']; ?>">
<tr>
<td width="35%">How many numbers to add:</td>
<td><input name="vars" type="text" id="vars" value="2" size="10"
maxlength="2"></td>
</tr>
<tr>
<td colspan="2"><div align="center">
<input name="submit" type="submit" id="submit" value="Next >">
</div></td>
</tr>
</form>
<?php
}
else
{
if(!is_numeric($_POST['vars']) || $_POST['vars'] <= "1")
{
echo "<a href=\"javascript:history.back(-1)\">Go back</a> and enter a
number or something greater then 1. DO NOT enter a letter or symbol.";
}
else
{
?>
<form name="add" action="module.php?id=<?php echo $HTTP_GET_VARS['id'];
?>&show=calculate" method="post">
<input type="hidden" name="vars" value="<?php echo $_POST['vars']; ?>">
<?php
$current = 1;
do
{
?>
<tr>
<td width="35%"><?php echo "Number ".$current.":"; ?></td>
<td><input name="num<?php echo $current; ?>" type="text" id="vars"
value="0" size="25"></td>
</tr>
<?php
$current++;
} while($current <= $_POST['vars'])
?>
<tr>
<td colspan="2"><div align="center">
<input name="add" type="submit" id="add" value="Next >">
</div></td>
</tr>
</form>
This is only a snippet, there is more to it but for simplicities sake...
Then I calculate it. My question is, how would I loop the adding? I hope you
understand this now...
