[solved] Category info - how to get category parents ID ?

[Paolo Bru]

Hi

in my shop I have 4 levels of depth of the categories.

 

When you are in a category of level 4 I would like to know who is the category of Level 2

The parameter id_parent know the higher category, but how do I know that the level 2?

I have to use this information in the file category.tpl

 

thanks

You mean you want to display the grandfather of category level 4?

Thanks for the replay

 

I have this structure

 

- category one
---->sub-category alpha
=====>sub sub-category beta
- category two
- category Three
- category four

 

when I'm in the sub-category alpha, I know the information of the category one through parameter id_parent.

When you are in the sub sub-category beta, how do I know the information of the category one?

I would go for a module, and use this query

 

'SELECT id_parent from ps_category WHERE id_category = ' . $current_id_parent

 

Where of course the variable is the $id_parent of the current category. You should create a new hook in the category, this way

Then you can either pass a variable to the hook, or grab the current category id like $id_category = Tools::getValue('id_category');

Of course, to get the parent use $category = new Category($id_category) and then $category->parent
