[SOLVED] Getting id_parent in a subcategory

[newuser78]

First things first - I started using Prestashop only a few weeks ago and have found it to be really good so kudos to the developers!

The shop is coming together nicely with new themes, modules, etc. except for one thing that I can't figure out - either because I am tired or can't find it! How do you get the id_parent when you on a subcategory page (when you are not using the tree thing)?

I would like to assign "selected" class to a parent category - this works if you go to a product detail page (product is in a category), e.g.

You are in Home > Laptops > Acer > Acer something - then I would like the Laptops button to be highlighted rather than Acer link (subcategory).

* Accessories
* iphone
* iPods
* Laptops
o Acer
o Toshiba

As far as I can see, the issue is the $currentCategoryId variable

{if $node.id == $currentCategoryId} class="selected"{/if}

Unfortunately, I am struggling to figure out the code in blockcategories.php -particularly line 128 and variable is passed with $smarty->assign('currentCategoryId', intval($_GET['id_category'])); so I guess I need to replace $_GET['id_category'] with something but I just can't figure it out!

Many thanks in advance!

here is how the path thing works for product page for instance:

in product.php you have:
'path' => ((isset($category->id) AND $category->id) ? Tools::getFullPath(intval($category->id), $product->name) : Tools::getFullPath(intval($product->id_default_category), $product->name))

then check Tools->getFullPath and Tools->getPath

you are able to customize the output in the way you like it

Hi Radu

many thanks for your post. I do see the code shown in product.php but how do I use this in modules/blockcategories/blockcategories.php?

Thanks again

[Radu]

sorry I did not understand your question at first. I am checking now to see how can I help you

[newuser78]

No worries Radu - attached is a rough design of the desired effect, I hope this clarifies the situation.

[newuser78]

I also attach another rough idea - a "nice-to-have". so basically, I would be happy to keep the following line in blockcategories.php:

$smarty->assign('currentCategoryId', intval($_GET['id_category']));

... and maybe do another line or two just for the purpose of menu styles? e.g.

$smarty->assign('parentCategoryId', intval(id_parent_from_database));

I don't know how to in the case of Prestashop unfortunately so any advice, etc. would be greatly appreciated!

ok here you go:
here is the demo: I won't keep it online for too long in this form
http://demo.ecommy.com/prestashop/category.php?id_category=4

1. modules/blockcategories/blockcategories.php
after:

$smarty->assign('currentCategoryId', intval($_GET['id_category']));

add:

$currentCategoryId = intval($_GET['id_category']);

after:

$smarty->assign('currentCategoryId', intval($cookie->last_visited_category));

add:

$currentCategoryId = intval($cookie->last_visited_category);

above:

$smarty->assign('blockCategTree', $blockCategTree);

add:

        
$topCategoryId = Category::getTopCategory($currentCategoryId, $resultIds);
$smarty->assign('topCategoryId', $topCategoryId);

2. modules/blockcategories/category-tree-branch.tpl
replace:

{$node.name|escape:htmlall:'UTF-8'}

with:

{$node.name|escape:htmlall:'UTF-8'}

3. themes/prestashop/css/global.css
replace:

div#categories_block_left ul.tree a.selected{
   color: #488c40;
   font-weight: bold;
}

with:

div#categories_block_left ul.tree a.selected{
   font-weight: bold;
}

div#categories_block_left ul.tree a#selected2{
   color: #488c40;
   font-weight: bold;
}

4. themes/prestashop/classes/Category.php
after:

    
public function updateGroup($list)
{
       $this->cleanGroups();
       if ($list AND sizeof($list))
           $this->addGroups($list);
}

add:

    
public function getTopCategory($selected, $cats) {
   if(intval($cats[$selected]['id_parent']) > 1) {
     return Category::getTopCategory($cats[$selected]['id_parent'], $cats);
   }
   else {
       return $selected;
   }
}

Once again thanks very much.

No worries, Radu - thanks very much for your help. It was very much appreciated - a lifesaver (and saved a few hair follicles!)! I shall definitely contribute whatever I can to this forum too.

Hey this is great, but I'm using PS 1.4 and things look different there. How would it be?
