Maybe I'm doing this wrong. So my main page, test.php, has three
arrays; one for price ($price), one for the names of products ($name)
and one for the quantity the user must input($qty). There's also an
input field for the users address. For the address field, I used solely
HTML: <input type="text" name="address" size="20" maxlength="30">
For the names, prices, and quantity fields, however, I use a for loop to
scroll through the names, prices, and create an input field for qty:
for($i = 0; $i < 3; $i++)
{
echo "<tr><td>$name[$i]</td><td>$price[$i]</td><td
align='center'><input type='text' name=$qty[$i] size='3'
maxlength='3'></td></tr>";
}
Now, for some reason, only the address data sends to the next script
(testprocess.php). Here's what I'm using to call the data for all the
variables:
$name = $_POST[$name];
$price = $_POST[$price];
$qty = $_POST[$qty];
$address = $_POST['address'];
I wonder, am I, passing the $name, $price, and $qty variables to the
testprocess.php page? Can I even pass php variables to another script
in such a manner? I guess I'm also not quite sure as to how to call
them either. Thanks.
