Based on your description it could litterally be coded one of a hundred
different ways. The way I would code a small problem like this is in a
monolithic logical construct such as the if/else statement below. This
allows you to be a little bit more careless how you construct the page.
Another conditional statement can be put above or below the form to capture
and perform whatever is needed on the $_POST["carmake"] array.
<form method="POST" value="test.php">
<?
if (isset($_POST['numcars']) && is_numeric($_POST['numcars']))
{
for ($i=1; $i<=$_POST['numcars']; $i++)
{
echo "Car # $i
<select name=\"carmake[]\">
<option selected value=''>-- Choose Car Make --</option>
<option>Chrysler</option>
<option>Chevy</option>
<option>Dodge</option>
<option>Ford</option>
</select><br>";
}
}
else
{
echo "How many cars? <input type=\"text\" name=\"numcars\"
value=\"\"><br>";
}
?>
<input type="submit" value="SUBMIT">
</form>
