Facebook has an extensive developers API. If they don't have an API for image retreival it's likely what you want to do would be considered illegal.

You'd better read the fine print and make sure you can do this.
I'm finding the only constant in software development is change it self.

That probably would help, eh? . Here ya go....
Also, just to clarify my program, this is a t-shirt order form and the $paypal and $check variables ccorrespond to checkboxes asking if the user wants to pay by check or with paypal.

Here is my corrected version:
1. You are/were including a full HTML document into an already existing defined HTML document. I removed the extraneous HTML from validation_functions.php4 incase they snuck in there by accident somehow.
2. You are testing a variable without the leading '$' which PHP uses to indicate a variable. Although it won't cause a parse error (syntactically it's acceptable) you won't get expected results because there is no constant named 'valid'
<br />
$valid = verifyAlphaNum($name);<br />
if(!valid) {<br />
$error_msg[] = "Name must be letters, spaces, dashes and ' only";<br />
}<br />
You should change these instances to:
<br />
$valid = verifyAlphaNum($name);<br />
if(!$valid) {<br />
$error_msg[] = "Name must be letters, spaces, dashes and ' only";<br />
}<br />
When I run your code I get the following error:
Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' in /var/www/test.php on line 87
Here is a tip: Always include the error information like above when asking for help with source code, and always wrap the source code in a [code] bracket so it's nicely formatted. It saves people from having to copy/psate and run your code like I had to do.
Anyways, with that error message in hand I can quickly jump to line 87 in my editor and immediately spot the problem(s):
echo "<div align="center"><li>" .$err. "<li></li></li></div>";
You using double quotes for the HTML attribute when it's already wrapped in double quotes
Change that code to this:
echo '<div align="center"><li>'.$err.'</li></div>
Notice how I use double quotes for the HTML attribute and single quotes for the PHP string? That was intentional and should be considered a best practice. Why?
PHP parser supports interpolated strings, meaning you can use a PHP variable in a double quoted string, like this:
$test = 'Some Value';
echo "Hello world this is a variable: $test";
The above would output something like:
Hello world this is a variable: Some Value
While this might seem cool (and it is handy in some circumstances) it should be a practice avoided like the plague.
1. It can lead to difficult to find bugs as it's not very explicit.
2. You incur a performance hit because PHP tokenizer needs to process double quoted strings
By using single quoted strings instead od double inside PHP you save yourself from the above problems.
Use concatenation, like you already do:
echo 'This is a '.$test.' string';
Or you can also use the C style sprintf functions, like so:
echo sprintf('This is a string: %s', $test);
One more issue I've spotted:
if (!$error_msg ) && ($paypal == 'on')
Should be:
if (!$error_msg && $paypal == 'on')
Cheers

Thanks Hockey! Yes, I noticed after posting my php4 function that my 'valids' were missing the $s. Also, the help on the concatenation helped a lot. This was throwing me off more than anything. Thanks again! The form (up to the rest of my commented-out code) works great!

You're off-topic. This is the Perl forum. You may want to check out the Python[^] forum. I just took a peak, and a well-known CP regular has already posted there. He can probably give you a hand with your Python questions.

Python, sounds like a pet to me 
but on a more serious note, all i know is that python is a scripting language. What exactly does that mean? why would i as a C# developer use python for?

Some background: I have taken a few measures to prevent SQL injection on my PHP/MySQL setup (currently WAMP for development, but will be LAMP for production server):
- In my users table, I have entered a "bad" user, with all the fields equal to 0.
- this is the first user in the table
- if a hacker tries to enter ' or ''=' in the uname field:
- (theoretically,) "bad" user will be first result, and
- (theoretically,) # of results will also be greater than 1 (more than 1 user)
- (theoretically,) the following code will prevent said hacker from gaining unauthorized access
- mysql_real_escape_string() function will be used to escape input when site is launched, but right now it is not in use to allow testing of common SQL injection methods.
- I have read that mysql_real_escape_string() has some vulnerabilities.
- I know mysql_real_escape_string() is more secure than addslashes().

I dunno... maybe I'm just paranoid... I just want to make sure to CMA to prevent liability problems, since this will be a commercial site.
P.S. I hope the markup helps read my programming - I know my lines tend to be fairly long...

To prevent SQL injection all you need to do is escape and use good validation. Other stuff can be a waste of time.

I usually use this function to prevent SQL injection, maybe it's useful for you :
function quote_smart($value)
{
if (get_magic_quotes_gpc())
{
$value = stripslashes($value);
}
if (!is_numeric($value))
{
$value = mysql_real_escape_string($value);
}
return $value;
}
Sorry for my English. I'm a freshman .
