global_variables = Off.....now what?

bjmitts

Ok..so I have PHP 4.3.0 dev up and running on my Apache 2.043 webserver. But the variables in my current code don't work anymore. I see that global_variables is defaulted to 'Off' in the PHP.ini file for security reasons...so I want to learn how to work with my variables with this 'Off'.

Here's what my code looks like now:

<html>
<head>
<title>Form Results</title>
</head>
<body>
<?php
/ This page receives and handles the data generated by "form.html". /
$FirstName = trim($FirstName);
$LastName = trim($LastName);
$Email = trim($Email);
$Comments = trim($Comments);
$Name = $FirstName . " " . $LastName;
print "Thank you $Name for your inquiry. \n";
print "An information packet will be sent to you at $Email shortly. \n";
print "You must be a friggin' moron if you think we're going to address your comments: $Comments";
$CryptName = crypt($Name);
print ("This is the crypt() version of your name: $CryptName\n");
?>
</body>
</html>

The form.html page is using this to send the data:

So...what do I need to change in my code to get the variables to work?

Thanks for any help you guys can provide. I appreciate it.

Ooops... I meant to say that register_globals is set to "off".

Sorry about that 🙂

Depending on how your data was sent to the script, you would use one of the superglobals....

If you're using POST, you would use $_POST['FirstName'] instead of just $FirstName as you have now.

If its GET, then use $_GET['FirstName']

Read: Predefined variables

HI...ok forgive me...I'm new. I've changed the code to the following:

<?php
/ This page receives and handles the data generated by "form.html". /
$FirstName = trim($POST['FirstName']);
$LastName = trim($POST['LastName']);
$Email = trim($POST['Email']);
$Comments = trim($POST['Comments']);
$Name = $POST['FirstName'] . " " . $POST['LastName'];
print "Thank you $POST['Name'] for your inquiry. \n";
print "An information packet will be sent to you at $POST['Email'] shortly. \n";
print "You must be a friggin' moron if you think we're going to address your comments: $POST['Comments']";
$CryptName = crypt($POST['Name']);
print ("This is the crypt() version of your name: $_POST['CryptName']\n");
?>

It still doesn't work 🙁 The page is returned, but the variables are not. POST is the method by the way.

maybe not exactly what you're looking for but deals with globals set to off and form w/ post, and a good example.

hth.

In your second script you may want to use your trimmed $FirstName and $LastName. That way if there are any spaces, they won't be in your $Name variable.

Here's another set of code. I append the Quantity and Discount variables at the end of the URL

.../conditionals.php?Quantity=100&Discount=45

my register_globals = off

What do I need to do to the following code to get this to work?

<?php
$Cost = 11.99;
$Tax = .006;
if ($_GET['Quantity']) {
$Quantity = abs($Quantity);
$Discount = abs($Discount);
$Tax++; // $Tax is now worth 1.06
$TotalCost = ($Cost $Quantity);
if ($TotalCost < 50) AND
($Discount)) {
print ("Unfortunately, your \$$Discount will not be applied because your total is under $50.\n");
}
if ($TotalCost >= 50) {
$TotalCost = $TotalCost - $Discount;
}
$TotalCost = $TotalCost $Tax;
$Payments = round ($TotalCost, 2) / 12;
// Print the Results
print ("You are about to order $Quantity widget(s) at \$$Cost each. \n");
print ("Your total with tax, less the \$$Discount, comes to $");
printf ("%01.2f", $TotalCost);
print (".\nYour monthly payment of $");
printf ("%01.2f", $Payments);
print (" will be due next month.\n");
}
?>

How do I declare variables now?

Example;

$iamdumb = yesiam

Do I need to change the above line of code to include $POST or $GET??

I'm lost. If you can't tell....I'm very new to PHP 🙁 Sorry for my stupidity

kinadian

These are the only 2 lines you need to change:
$Quantity = abs($Quantity);
$Discount = abs($Discount);

They should read:
$Quantity = abs($GET['Quantity'];
$Discount = abs($GET['Discount'];

You need to use $_GET because you are including the variable definitions in the url of the document (the ?quantiy=100&Discount=45 stuff).

If you wanted to use $_POST then use the method POST in your form tag.

Your best bet is to find a nice tutorial online to learn PHP from.

I can suggest this one as a starter: http://www.webmasterbase.com/article/228

Hey Kinadian....thanks for the tip. You were right. That worked. I went to some of my other pages that weren't working properly and got them up and running as well.

Thanks again. I appreciate it.

Later,
