Hi Nemo,

I just created a db table to insert the category_id.Before that i need to get the category_id.
Hope you understand.

It depends on where you try to get the category id. Is it inside the function of a module, a module hooked on a action, a function inside your own Front/Admin controller?

Try to give a more detailed scenario of what you're trying to do.

[vazeem]

Its inside a module.i override the AdminCategoriesController.php to my module.In this php file i want to get the id_category.

 

$id_category = (int)Tools::getValue('id_category');

echo $id_category;

 

I try this.But shows displays none.

The code you are trying is working in renderForm().

It also works in renderList() if you're in a parent category other than Home.

Instead of echo use d($id_category) to output only the variable value.

 

A better alternative to get the category id if you're in a function that is fired after the init() function is:

$this->_category->id;
