PHP中的多步形式 - MVC应用程序

Question

I'm about to program a mutistep form in my MVC App (Self-made MVC framework) in which no data is to be inserted until the last step is finished.

I got the following issues/questions

• I'd really like to find a kind of pattern to solve this problem, is there any?
• I want it to be easy the perform a go back action, and get the data back in the last step. Question: Is a session the only way to pass the data? Are get parameter maybe a better/simpler option?
• How have you solved this problem before

Answer 1

Look how they implemented it in Symfony, it's quite well built in that framework.

You just have to download it and look in your project: /lib/symfony/form

Basically you should create classes for each one of your form inputs;

• you could always create different and complex ones, then;
• you go create validator classes for each of them (maybe configurable),
• you store your data in PHP objects that you save in the session or cookie,

I would not recommend saving using parameters, too many of them, you have to consider URL max size and browser limits.
