8.4.2 User Input - Continued

We entered some text, submitted the form, and our browser now shows this:

Netscape: Untitled

File Edit View Go Communicator

Location:

You entered: Jack & Jill

What happened was:

We submitted the form, with the <INPUT> tag txt set to Jack nbsp;& nbsp;Jill . Vortex automatically copies any form data - GET as well as POST - to Vortex variables of the same name. So our $txt variable is set to Jack nbsp;& nbsp;Jill .
main prints the form - pre-filled with our submitted text because $txt is set.
The main function ends, and the script ends.

HTML escapement

An important feature to note here is that we entered data that needs HTML escapement when printed - the ampersand (& ). Vortex automatically HTML escapes variables when they're printed, so we don't need to worry about it. (We can verify this by looking at the HTML source in our browser - the & is shown as & .)
