With a continuation of their previous article, WebReference has posted part two of their "How to Interact with Web Forms" series - an excerpt from the PHP Phrasebook (Sams).

They build on the previous code, showing how to:

• preselect items from a multiple select list,
• process image submit buttons
• checking the mandatory fields
• checking the values of select lists

They wrap it all up with two handy concepts - how to write out your data to a form and send it off in email form to the location of your choosing and working with the files uploaded via a form.
