home.tpl中的OpenCart变量

Question

So i'm trying to display the categories on the homepage in a custom theme of OpenCart.

In the header.tpl you can use variables as $categories and so fort, but when I want to use these variables in the home.tpl file, it says it doesn't exists.

Is there any way to make these variables working in the home.tpl file? I can't find any line in the header.tpl that includes a PHP files where all these variables can be found.

Answer 1

You need to look into the controller of header.tpl called header.php In there, you can find the part where categories is assigned ( line 93 to 124 )

Paste this part into the home.php ( on line 18 )

Now the variable categories is available.

Answer 2

(1) search in common/header.php @ class ControllerCommonHeader for the code fragment that constructs categories array, in my project (v 1.5.5.1) I have it like that

 $this->data['categories'] = array(); $categories = $this->model_catalog_category->getCategories(0); foreach ($categories as $category) { ... 

(2) Copy that code snippet to common/home.php @ class ControllerCommonHome @ function index() , now you can use it in home.tpl
