Block Categories - show only current category

[herchri]

Hi Guys,

 

i use julien breux horizontal navigation menu. I search a synchronized version of the block categories modul. My need is the following: If I select a category via the horizontal menu, only the selected category and it's subcategories should appear in the categories block in the left hook.

 

Does anyone know a modul with this functionality or could give me some hints were I need to modify the modul?

 

Merry Christmas to everyone and I appreciate any help. Thanks.

Hi

 

You can take the blocktopmenu from the 1.5 theme and itegrate it in your theme.

 

Merry Christmas

 

EDIT:

sorry, I didn't read your post carefully. Solution in my next post

Hi Snade,

 

thanks for you reply. I already have a horizontal top menu.

I've attached a screenshot of my actual test template. I want to change the left categories block. If I select the category 'iPods' in the horizontal top menu, only iPods and it's 2 subcategories should appear in the left category list.

 

Do you know how to change it?

 

thanks and kind regards

Chris

So, I came up with a solution but I cant get it fully working.

The idea is to have display:none; on all <li> elements in the menu, and change that to display:block, for the selected category.

 

It sounds easy, and it is if you dont have subcategories.

 

So first I added display:none to the #categories_block_left li

and display:block to #categories_block_left li ul li (when you have selected a main category, the subcategories need to show up)

 

then I edited category-tree-branch like that

<li {if isset($last) && $last == 'true'}class="last" {/if}{if isset($currentCategoryId) && ($node.id == $currentCategoryId)}style="display:block"{/if}>

which just add style="display:block" to the <li> when this is the current category.

 

works fine for the main categories.

 

But when you select a subcategory, the parent category <li> no longer get display:block (which is perfectly normal when you think about it.... )

 

Somehow we have to link the currentcategoryid to the parent_id or something...

 

 

Maybe someone else can give a clue how this can be achieved ?

 

 

@herchri Change the name of the topic to "Block Categories - show only current category" or something like that. Probably it will drive more attention than just block categories

many thanks for you help.

I tried editing where condition of the sql statement in the blockcategories.php, but I had no luck with it.

Does anyone have other hints?

[herchri]

Do I understand the modul correctly?

 

blockcategories.tpl delivers the main categories and category-tree-branch.tpl delivers the subcategories and highlights the active category ?

 

Now I tried to add an 'if' condition in block categories.tpl , but I think I'm still on the wrong way ... I tried to add the following:

 

    {if isset($currentCategoryId) && ($node.id == $currentCategoryId)}
    {foreach from=$blockCategTree.children item=child name=blockCategTree}
	    {if $smarty.foreach.blockCategTree.last}
		    {include file="$branche_tpl_path" node=$child  last='true'}
	    {else}
		    {include file="$branche_tpl_path" node=$child}

	    {/if}
    {/foreach}
    {/if}

[Snade]

Both main categories and subcategories are generated in category-tree-branch. That is the problem, we need to make an if statement not only for current category, but for current category and its parent categories.

 

 

Here is an idea, but I want you to try it since I dont have time.

 

{if isset($id_category_parent) && ($node.id == $id_category_parent)}style="display:block"{/if}

(this will not be the final code, just test it to see if its working for parent category)

[Snade]

It looks like we are doing it wrong by trying to trick this only with smarty. Probably there is a way to do it like that, but this guy here has done the job in the blockcategory.php file - http://www.prestashop.com/forums/topic/147686-solved-blockcategory-display-only-from-level1/

 

 

 

cheers

[herchri]

Sounds great ... I'll test it ... thanks

[herchri]

Ok, looks much better now. Great. Now I've only one issue. I want, that the label of the left categories box - at the moment 'Kategorien' - gets automatically exchanged by the highest parent category - in my example 'iPods' -

 

Does anyone have an idea for this?

[herchri]

Does nobody have an idea?

[herchri]

Can anyone help me on this?

Hi

check this topic to see if the solutions there work for you http://www.prestashop.com/forums/topic/117702-solved-display-parent-category-inside-a-category/

[herchri]

Many thanks Snade ... I'll check it and maybe it pushs me in the right direction

That's how I solved it, using Snade's idea + javascript call to parent tags:

 

1) in category-tree-branch.tpl i wrote

<li class="{if isset($last) && $last == 'true'}last {/if} menulist" {if isset($currentCategoryId) && ($node.id == $currentCategoryId)}id="currentli"{/if}>

2) add new javascript function in tools.js (it could be any .js file, called on your page)

function  changevisibility()
{
document.getElementById('currentli').parentNode.parentNode.id = "parid";
}

3) add in <body> tage on header.tpl:

onload="changevisibility()"

 

So this function will be called when our page is just loaded

4) add in global.css

#categories_block_left li {display:none;}
li#parid, li#parid #currentli,  li#parid ul, li#parid ul li, #currentli, #currentli ul li{display: block !important;}

[Guest masquemortal]

well thank you both for sharing that solution!, maybe will test it later on my shop, it could be usefull, thanks again

[uGoGo]

Did it solve your problem?

[Guest masquemortal]

last chuvachon solution for changing the name of categorie block title, didnt work for me.

 

The other one solution for showing only parent categorie in block, works fine on 1.4.6.2

[Shwamateur]

So I wouldn't say I solved this because it doesn't work for all cases.

But I use this modified version of the blockcategories module.

 

Since on my webpage the categories block is only displayed on category pages, this works good, but I know that it doesn't work properly on product pages.

 

In order to solve this you should modify the getTree method on blockcategories_mod.php, assigning the initial category id (the one that conveniences you) to $id_category.

 

I hope this is useful for somebody!

I want to display the home categories for all pages in the left sidebar. It works fine.

 

Then, For one of the category page I need to display the current category in the left sidebar.

 

How can I do? How can I enable current category for one of the category page I have  an  idea. I have to change the home category to a current category for that particular category.

 

But I don't know how to achieve using code?

 

Can anyone help, please..
