get category by id and sub categories and show under another category page

[Abdul]

Hi, i am new to prestashop and using prestashop 1.7. 

I wanna show one parent category with its sub categories data/information into another parent category page in category.tpl file.

I have created frontcontroller
 

public static function getCategoryName($id){

$category = new Category ($id,Context::getContext()->language->id);

return $category->name;

}

and displaying category name by id 

{FrontController::getCategoryName(273)}

273 is category id.

now i can not find the way to show sub categories and their cover images of category id 273

Hi,

Use getChildren() function to retrieve the sub-categories of a category. Refer to Category.php file inside the classes folder to check the details of the funcation.

getChildren(273, Context::getContext()->language->id);

not displaying anything can you guide me how could i use this code in .tpl file

To display the same in .tpl file, you need to assign the variable from the controller file. This function can't be called directly into tpl.

In the controller, write the code like.

$subcategories = getChildren(273, Context::getContext()->language->id);

$this->conext->smarty->assign('subcategories', $subcategories);

In the tpl file, you can access the subcategories using the variable {$subcategories} but you need to run a loop in the tpl to display the subcategories.
