main.php - only certain categories

[spevoli]

Hi

this code I have from @teseo "thanks"

Code: [Select]

<?php
function cust_show_only_selected_categories() {
    if(osc_is_home_page()) {
        $categoriesToShow = array(31, 59, 8, 75); // Put here Id's of parent categories or subcategories (no sub-subcategories)
    
        $categories = Category::newInstance()->toTree();
        foreach ($categories as $key => $cat) {
            if (!in_array($cat['pk_i_id'], $categoriesToShow)) {
                foreach ($cat['categories'] as $key2 => $subcat) {
                    if(!in_array($subcat['pk_i_id'], $categoriesToShow)) {
                        unset($categories[$key]['categories'][$key2]);
                    }
                }
    
                if (!$categories[$key]['categories']) unset($categories[$key]);
            }
        }
    
        View::newInstance()->_exportVariableToView('categories', $categories);
    }
}

osc_add_hook('before_html', 'cust_show_only_selected_categories');
?>
does not display correctly ...
It will display all categories ... continue

someone has a tip?

thanks, spevoli

Works for me on Infinity as well... Did you put this function at the very bottom of infinity/functions.php?

Or maybe you have there another function manipulating categories list just as this function does?

Hi Teseo!

in the "functions.php" I've changed a lot ...

for the area "category" not ...
the code I added at the bottom ...
There will be no error message
