OOP Class Naming

[spires]

Hi

 

I'm doing some OOP

But can not find a way to make the class name dynamic.

I'm sure there must be a way of doing it, as I use this a lot, i'm sure other must also.

 

This is what I have:

	$wrapperLCID = $newListWrappers->list_category_id;
	$wrapperName = $newListWrappers->name;

		if($wrapperLCID==1){
		   $newParent = Business_solutions_cat::find_all();
		}elseif($wrapperLCID==2){
		   $newParent = Blackberry_cat::find_all();
		}elseif($wrapperLCID==3){
		   $Pcategory = Case_studies_cat::find_all();
		}elseif($wrapperLCID==4){
		   $Pcategory = Stand_alone_cat::find_all();
		}elseif($wrapperLCID==5){
		   $newParent = Reasons_cat::find_all();
		}elseif($wrapperLCID==6){
		   $newParent = Charity_cat::find_all();
		}

 

 

This Is What I want:

	$wrapperLCID = $newListWrappers->list_category_id;
	$wrapperName = $newListWrappers->name;

	$newParent = $wrapperName::find_all();

 

 

Thanks for your help

You need to use the Factory Method here:

 

abstract class WrapperFactory
{
   public static function GetById($id)
   {
      switch($id)
      {
         case 1:
            return new Business_solutions_cat();
            break;

         case 2:
            return new Blackberry_cat();
            break;

         // etc.
      }
   }
}

$wrapper = WrapperFactory::GetById($id);

$newParent = $wrapper::findAll();

The code you posted should work in PHP 5.3.  This is the way in earlier versions:

 

$newParent = call_user_func(array($wrapperName, 'find_all'));

[spires]

$newParent = call_user_func(array($wrapperName, 'find_all'));

 

Works perfect

 

Thanks for that.

 

Do you know when 5.3 will be stable on all hosting?

I'm only on 5.2.17 currently.

 

Thanks Again

I have no idea.  We still get questions about things not working on PHP 4!

Hi.

 

Thanks again.

 

But what If I want to pass the class an ID, or multiple variables?

 

E.G: find_by_id(10);

call_user_func_array()

[spires]

Do you mean like this?

 

$newChild = call_user_func_array(array($className, 'find_by_id'), array($LPlistID));

$newChild = call_user_func_array(array($className, 'find_by_id'), array($LPlistID));

 

Yup. See the manual for more information
