Usually that is done by generating dynamically a single image using the
GD extension.

You may want to take a look at this forms generation class to perform
that kind of validation. It generates an image with a random text and a
noise image to make the text a little fuzzy and harder to crack by robots.

Here is a screenshot of the text:

Take a look at the test_captcha_input.php example script to learn how
the class can simplify this task for you using this plug-in:

[PHP-DB] Forms with letter security

2006-06-16 Thread Ron Piggott (PHP)
I have a set of graphical letters A to Z.  I want some displayed and
then keyed into a security field to verify a person is submitting the
form.  I have seen these used before on shopping carts.  

I know about creating salts to select which letters to choose.

What I am wondering is if there is a way to join the letters together
instead of having 6 different images displayed.

RE: [PHP-DB] how to get the referrer page details

2006-06-16 Thread Dwight Altman
I use $_SERVER['REMOTE_ADDR'], but the notes at http://us2.php.net/getenv
say you may want to also use HTTP_X_FORWARDED_FOR (and not even getenv but
$_SERVER as you were attempting).

Regards,
Dwight

$query = "INSERT INTO student (ssno,lname,fname) VALUES (12345,'','');"

You pass emtpy strings. ('') Try this

$query = "INSERT INTO student (ssno,lname,fname) VALUES (12345,NULL,NULL);"

That how the things are. Sometimes others do not act like one likes to. You 
should respect that some individuals do not want you to get that information. 
I bet, that is not really a big thing, isn't it?
