Forms with variable outputs?

[JimTheNim]

Hi Everyone,

My first post here having only recently joined. Salut!

I purchased the 'Site Point - Build Your Own Database Driven Website Using PHP & MySQL' book, but was hoping someone would be able to clarify one minor point (major for me!).

I want to create a simple form where the end user selects one option from a drop down list, this selection will then dictate what the following selection would be.

For example - You select 'manufacturer of machine' this will then produce another drop down list with models from that particular company/make.

Can this be done solely in php or do I need to add another application (and ultimately Site Point book!) into the mix?

Thank you in advance for any advice offered.

Jim

Hi there Jim and welcome to Sitepoint

What you are referring to is called a "Chained Select" and it can be done in PHP alone however it is more suited to Javascript.

PHP is a server side language meaning that anything it does has to be sent to the server for processing and then sent back to the browser - and a page refresh.
You will need some Javascript too for the user interaction.

Have a look at: http://www.dynamicdrive.com/dynamici...ects/index.htm or

for 2 good examples.
