Can $ not register?!?

I am using Dreamweaver MX and when I put in the following code:

<?php

$qty4000 = $HTTP_POST_VARS['qty4000'];
$qty4000-A = $HTTP_POST_VARS['qty4000-A'];
$qtyM4000 = $HTTP_POST_VARS['qtyM4000'];

  echo '<p>Order Processed at';

echo date ('H:i, jS F Y ');
echo '</p>';

echo '<p>Your Order is as follows:</p>';
echo $qty4000.' SCEPTER 4000<br />';
echo $qty4000-A.' SCEPTER 4000-A<br />';
echo $qtyM4000.' SCEPTER M4000<br />';
?>

(the "qty4000" and others are the names of the fields from my input page)

I receive the following error:

"parse error on line 14"

Line 14 ---> $qty4000-A = $HTTP_POST_VARS['qty4000-A'];

But based on some modifications that I have done to the code (such as changing the field names from "qty4000" to "4000", which is what I really wanted anyway), it seems as if it's not recognizing the $ symbol... is that possible?

Here is the error message:

"parse error, expecting T_VARIABLE' or'$'' on line 13"

Line 13---> $4000 = $HTTP_POST_VARS['4000'];

What's a noobie to do?

the problem is most likely $qty4000-A. variables cannot contain "-". Variables can only be made up of letters, numbers, and underscores. from the manual, " Variable names follow the same rules as other labels in PHP. A valid variable name starts with a letter or underscore, followed by any number of letters, numbers, or underscores."

I just changed the 4000-A to 4000A, but I got the same error message:

"parse error, expecting T_VARIABLE' or'$'' in processorder.php on line 13"

Line 13 ---> $4000 = $HTTP_POST_VARS['4000'];

So it's detecting an error before it even gets to the 4000-A, because the 4000-A is on line 14.

Anything else?

oh wait... my bad.

I just put an underscore in front of the 4000, like you quoted from the manual it can't start with a number.

I put _4000 instead of just 4000 and it seems to work now.

Thanks

I think it's also worth pointing out that $HTTP_POST_VARS is outdated and that you should use $_POST now.

Also, be sure to mark this thread resolved.

Oh, good thing you told me that it was outdated. I'm just reading a book that said that it was compatible with all versions, whereas the $_POST[] was not as safe to use.

I'll mark this thread resolved. Thanks for all your guys' help. Feel free to email me about getting a good deal on paintball gear if you're interested. That's my way of thanks. 🙂
