Major Problem with subcategories

[krislicky]

Hey there, I really hope someone can help with this as I'm tearing my hair out!

A client has asked if all the subcategories of the second level of categories can be shown within the 3rd level of subcategories. I think I explained that strangely. Go here:

http://www.yankeestore.co.uk/130-all

As you can see, there are no subcategories for this section, but my client would like the images for all of the other subcategories within this parent group to be displayed i.e. this particular category would always show all, fresh, fruit, floral, food & spice and festive, as would be the same for each of these.

Could anyone shed any light on this?

Ive attached a file to demonstrate how it would look because I dont think im being very clear

[krislicky]

seriously? no-one?

So you want the subcategories of the parent category displayed when there are no subcategories for the current category? To do that, try changing line 50 of category.php from:

$subCategories = $category->getSubCategories(intval($cookie->id_lang));

to:

$subCategories = $category->getSubCategories(intval($cookie->id_lang));
if (sizeof($subCategories) == 0 AND intval($category->id_parent) > 1)
{
  $parentCategory = new Category(intval($category->id_parent), intval($cookie->id_lang));
  $subCategories = $parentCategory->getSubCategories(intval($cookie->id_lang));
}

Once again Rocky... you did it !
Now, on my subcategory page (A1), I can show all other subcategories of parent (A2, A3, A4, ....).

Next question : how can I show this also on a product page ?

[rocky]

You'll need to add similar code to product.php to pass in the subcategories. Something like:

$category = new Category($product->id_category_default, intval($cookie->id_lang));
$subCategories = $category->getSubCategories(intval($cookie->id_lang));
if (sizeof($subCategories) == 0 AND intval($category->id_parent) > 1)
{
  $parentCategory = new Category(intval($category->id_parent), intval($cookie->id_lang));
  $subCategories = $parentCategory->getSubCategories(intval($cookie->id_lang));
}

Then you'll have to copy the subcategory code from category.tpl into product.tpl.

Thank you !

Where should I put your code in product.php ?

I have added it at line 172.
The problem is that now the category ID of a product is its default category ID.
And that's making the breadcrumb and other things go wrong.

Also in $category, some arrays are now x3 when they should be single.

Thanks for your help....

I forgot to include id_lang when creating the Category object above. I've updated the code. It should fix the array instead of single problem.

You could replace $product->id_category_default above with:

intval($cookie->last_visited_category)

They are the only two categories you have access to from the product page.

This could help a lot.
The problem is that my {$cookie} says : Cookie Object (0)
Damn !

Hi Rocky, Emmanuel,

Here I come several months after the topic, am I too late ?
I have the 2 same targets as Emmanuel :

- target 1 : on the page for subcategory=A1, display links list A1,A2,A3... instead of [no subcategories] : done, thanks to the piece of code above, i.e. thanks to you !

- target 2 : on the page for product X in subcat A1, display again links list A1, A2, A3... TO DO !

I tried hard to understand where to insert the code you gave, Rocky, but I am afraid Smarty still remains this far a foreign language to me ... I'm working hard on it !

So if you Emmanuel or Rocky, can indicate me what I did wrong, this is what I did, and how I got... no results :

In product.php, I turned line 170 :

if (!$category)
   $category = new Category($product->id_category_default, intval($cookie->id_lang));    

into :

$category = new Category(intval($cookie->last_visited_category) , intval($cookie->id_lang));
$subCategories = $category->getSubCategories(intval($cookie->id_lang));
if (sizeof($subCategories) == 0 AND intval($category->id_parent) > 1)
{  $parentCategory = new Category(intval($category->id_parent), intval($cookie->id_lang));
   $subCategories = $parentCategory->getSubCategories(intval($cookie->id_lang));
}

and in product.tpl, I added :

>
{if isset($subcategories)}
</pre>
<ul>
       {foreach from=$subcategories item=subcategory}
getCategoryLink($subcategory.id_category, $subcategory.link_rewrite)|escape:'htmlall':'UTF-8'}">{$subcategory.name|escape:'htmlall':'UTF-8'}
       {/foreach}
</ul>
<br>{else} <br>   no subategories defined, go back to school<br>{/if

What did I miss ?...

Hello,

I got the same problem.
I succeed to do the part 1 but in the part 2 the $subcategories still empty while the $category contains data.

Any ideas?

Thanks

[Rom Soul]

Sorry Lagachette,

I sent desperate PMs, but never got my answer for part 2, and eventually had to display something else in my submenu
Good luck : if you find the solution, I am still interested !
