design pattern for this case ??

[PHPycho]

Hello forums!!
I would like to know which design pattern would be useful in the following case:
There are many modules and each module consists of many actions(multi stage actions). for example:
Module A consists of action1.1, action1.2, action1.3 etc.
Module B consists of action2.1, action2.2, action2.3 etc.
The actions can be sequential(For example:action1.1-> action1.2-> action1.3) or can be altered as per preferences( For example:action1.1-> action1.3-> action1.2) within a module.

How this can be accomplished using OOP design pattern or else? Any ideas ??
Thanks in advance for the valueable help.

A bit vague, but sounds like it might possibly be a case for the decorator pattern.

• Are modules classes and actions methods?
  -- yes
• Do they need additional Parameters?
  -- may or may not
• Are there requirements to the module configuration?
  -- Class runs the methods as sequence of methods(like i stated: action1.1-> action1.2-> action1.3) in a default but it can be configureable also

Hope this may help.

I think you are looking for method chaining which was introduced in PHP5. If you google "php method chaining" you should find lots of pages and tutorials for this.

I think method chaining is not appropriate for this as the actions mentioned ie action1.1, action1.2 etc may involve form submission .
Any other patterns for such ?
