Extensions in product display page..

[sathyashrayan]

I am on the process of learning VM.20.. I understood the following way of customizing a product display page..
 
  a)Copy the following file from [path]/components/com_virtuemart/views/productdetails/default.php to the [path]/templates/[our template]/html/com_virtuemart/productdetails/

  b)Then in the file [path]/templates/[our template]/html/com_virtuemart/productdetails/default.php we have to see the comments so that we can customize the divs for display.

My doubt is.. The new VM 2.0 is MVC based. So i could change the model to make an functionality. But it will get lost in further core update. So how can I face this issue? Abstract and create a plugin? And how can I display that in a template page? May be in the productdetails page? Please guide.. Thanks

what are you trying to do?

Learn By trial and error..On that learning process i just wanted to know what if any extension made and need to be shown? May be some extension (extra functionality)  in product , category ect. Do i need to create a plugin and show it in default.php? I am confused.

it depends

IF the field is a custom column in the product table, you can access it like this

<?php echo $this->product->COLUMN_name ?>

IF the field is a custom column in the category table, you can access it like this

<?php echo $this->category->COLUMN_name ?>

THEN: if its a custom way that product options are displayed. You would create a plugin.

SO< I dont know what u mean by extension made. ( a joomla extension)?
OR, are you talking about extending vmart functionality?

OR, are you talking about customizing the output?

Functionality is ideally altered/enhanced by using plugins - the core should not be edited.

Output is altered by changing views (templates & css), with template overrides.
