You're going to want to use PHP. PHP is the easiest language to use to get input from a form and dynamically generate content (generate content based on the form input).
An example of some PHP code:
PHP Code:
<?php
// if the submit button is clicked
if (isset($_POST['submit']))
{
// capture the variables submitted
$name = $_POST['name'];
$content = $_POST['content'];
// echo them back to the user in a sentence
echo "Hello, $name! $content";
}
?>
There are two great ways to learn PHP. One is to check out the book "Head First PHP & MySQL" from the library, or you can head over to
W3Schools Online Web Tutorials and look at their tutorials.
If you need more help, I'm a veritable expert with PHP and I'll be happy to answer any questions.
Good luck
